As a temperature control system equipped with this type of temperature control device and control device, the applicant discloses the invention of a connected operation system equipped with a plurality of chillers and a centralized control device that centrally controls each chiller in the following patent documents. is doing. In this case, each chiller has an internal cooling system that cools the coolant (cooling water) by the refrigeration cycle, an outside air cooling system that cools the coolant by heat exchange with the outside air, and a part to be cooled (to which the coolant is supplied) and a control system (chiller controller) that controls the cooling of the cooling liquid by the internal cooling system and the outside air cooling system and the pumping of the cooling liquid by the pumping pump.

In addition, the centralized control device controls the control system of each chiller according to the load factor of the system, and operates the required number of chillers to supply the required amount of cooling liquid to the cooled part. It is configured to be able to execute processing. Specifically, the centralized control unit monitors the load factor of the system, and operates some chillers (cooling the coolant and supply), and resumes the operation of the stopped chiller when the second monitoring load factor set in advance is exceeded.

In addition, the centralized control device controls each chiller so that the amounts of cooling liquid supplied from the operating chillers to the parts to be cooled become equal to each other. Specifically, when stopping the operation of one of the chillers, the total supply amount of the cooling liquid supplied to the cooled part from the connected operation system before stopping the operation of one of the chillers is Separately supply cooling liquid to all chillers that continue to operate after stopping, and when restarting the operation of any chiller, the part to be cooled from the connected operation system before restarting the operation of any chiller The total supply of cooling liquid being supplied to is divided among all the chillers that will be in operation after the resumption of operation of any chiller to supply cooling liquid to each.

As a result, in the connected operation system disclosed by the applicant, it is possible to reliably supply the required amount of cooling liquid from the connected operation system to the parts to be cooled, and to provide the necessary cooling for the parts to be cooled. By stopping the operation of some chillers when the amount of liquid is small (when the load factor becomes small), it is possible to reduce the power consumption of the connected operation system.

Japanese Patent No. 5685782 (pages 6-14, Figures 1-7)

However, the linked operation system disclosed by the applicant has the following problems to be improved. Specifically, in the linked operation system described above, the centralized control unit regulates the operation of some chillers depending on the load factor of the operating system, i.e., the amount of coolant required in the parts to be cooled. and restarting the operation of the chiller that has been stopped, reducing the waste of power (power consumption by continuing unnecessary chiller operation) due to the linked operation system. configuration is adopted. In this case, the above-described connected operation system employs a configuration in which the centralized control device controls each chiller so that the amounts of cooling liquid supplied from the operating chillers to the parts to be cooled are equal to each other.

On the other hand, in this type of connected operation system, the connection position of the chiller to the supply pipe for supplying the cooling liquid to the cooled part (supply pipe length between the cooled part and each chiller) is different for each chiller. can be In this case, in a chiller with a long supply pipe length, the pressure loss that occurs in the supply pipe (pressure drop due to the presence of resistance when the cooling liquid moves in the supply pipe) is greater than in a chiller with a short supply pipe length. As a result, the amount of pressurization required to pump the cooling liquid to the part to be cooled increases (the cooling liquid needs to be pressurized to a higher pressure), and as a result, the power consumption by the pumping pump increases. tend to be more. In addition, in a chiller with a large amount of pressurization by the pressure pump, compared to a chiller with a small amount of pressure by the pressure pump, the amount of temperature rise of the cooling liquid during pressurization is large, so the cooling liquid is lowered to the target temperature. There is also a tendency for the amount of power consumed by the internal cooling system (blower fan and compressor) and the power consumption per unit time by the external air cooling system (blower fan) to increase.

Furthermore, in this type of linked operation system, the temperature and conditions (progress of wear of mechanical parts, etc.) at the installation location may differ from chiller to chiller. In this case, a chiller installed in a place with a high temperature (for example, a place exposed to direct sunlight, a place with poor ventilation, or a place close to a heat source such as a boiler) should not be placed in a place with a low temperature (a shaded place or Compared to a chiller installed in a good place), the cooling efficiency of the cooling liquid due to the internal cooling system decreases due to the decrease in the condensation efficiency of the refrigerant in the condenser, and the cooling efficiency of the cooling liquid due to the outside air cooling system decreases significantly. Accordingly, the amount of power consumed by the internal cooling system (blowing fan and compressor) and the power consumption of the outside air cooling system (blowing fan) tend to increase. In addition, in a chiller in poor condition, compared to a chiller in good condition, the pumping efficiency of the cooling liquid by the pressure pump and the cooling efficiency of the cooling liquid by the internal cooling system and the outside air cooling system are lowered. Power consumption tends to increase.

However, in the connected operation system disclosed by the applicant, without considering the difference in the individual power consumption of each chiller due to the difference in the supply pipe length as described above and the difference in the temperature and conditions of the installation location A necessary and sufficient number of chillers capable of supplying the required amount of cooling water to the cooled parts are operated under the same operating conditions. For this reason, when stopping the operation of one of the chillers, there is a possibility that the chiller with the lowest individual power consumption among the operating chillers is stopped (that is, stopping the other chillers is more control that can further reduce the overall power consumption of the system). In addition, when restarting the operation of one of the chillers, there is a possibility that the chiller with a large individual power consumption among the stopped chillers is restarting the operation (that is, the other chiller is restarted may be controlled so that the amount of increase in overall power consumption is small).

In this case, considering the difference in supply pipe length and the difference in temperature and conditions at the installation location, adopt a configuration in which the order of stopping the operation of each chiller and the order of restarting the operation of each chiller can be set in advance. It is also possible. However, for those who are not familiar with the operating principle of this type of system, it is necessary to grasp the supply pipe length of each chiller, the temperature and conditions of the installation location, etc., and estimate the individual power consumption of each chiller from the grasped items. It is difficult to determine the preferred order of stopping and the preferred order of restarting. In addition, at the site of use of this type of system, the number of connections of the cooled parts, the operating state, and the wiring configuration of the supply pipes and return pipes may be frequently changed. Therefore, even a person who is familiar with the operating principle of this type of system cannot correctly estimate the individual power consumption of each chiller by grasping the conditions of the parts to be cooled and the installation conditions of each temperature control device. is difficult. Therefore, it is very difficult to further reduce the total power consumption by presetting the order of stopping the operation of each chiller and the order of restarting the operation of each chiller.

In addition, a temperature control system (connected operation system) has been described as an example. A temperature control system that changes both the operation rates of each temperature control device also has the same problem as the above-described connected operation system.

Embodiments of a control device and a temperature control system will be described below with reference to the accompanying drawings.

First, the configuration of temperature control system 100 will be described with reference to the accompanying drawings.

The temperature control system 100 shown in FIG. 1 is a circulating cooling liquid supply system, which is an example of a "temperature control system". ), and configured to be able to supply cooling liquid Wa (antifreeze, tap water, pure water, etc.: an example of "heat transfer liquid") cooled to a preset temperature to supply object X such as manufacturing equipment It is This temperature control system 100 includes a control device 1, a plurality of temperature control devices 2a, 2b, . ), a temperature sensor 3 and a pressure sensor 4 .

In this case, in the temperature adjustment system 100 of this example, the liquid outlet of each temperature adjustment device 2 is connected to the supply pipe Ps for supplying the cooling liquid Wa to the supply object X, and the supply object X A liquid inlet of each temperature control device 2 is connected to a return pipe Pr for recovering the cooling liquid Wa whose temperature is raised by cooling the object (exchanging heat with the object). Further, the temperature sensor 3 and the pressure sensor 4 are connected between the temperature adjustment device 2 (in this example, the temperature adjustment device 2a) connected to the most downstream side of the feed pipe Ps and the supply target X (that is, the feed It is disposed at a portion of the pipe Ps through which all the coolant Wa pressure-fed from each temperature control device 2 passes.

On the other hand, the control device 1 is an example of a “control device” and is configured to be able to control the operation of each temperature adjustment device 2 in a centralized manner. Specifically, as shown in FIG. 2, the control device 1 includes an operation unit 11, a display unit 12, a control unit 13, and a storage unit 14. As shown in FIG. The operation unit 11 controls the temperature of the cooling liquid Wa supplied from the temperature adjustment system 100 to the supply target X (the temperature specified by the user of the temperature adjustment system 100: hereinafter also referred to as “overall target temperature ASvs”), temperature adjustment Operation of setting (designating) operating conditions such as the pressure of the coolant Wa supplied from the system 100 to the supply target X (the pressure designated by the user of the temperature adjustment system 100: hereinafter also referred to as "overall target pressure BSvs") , and an operation switch for instructing start/stop of various processes by the control unit 13, and outputs an operation signal to the control unit 13 according to the switch operation. Under the control of the control unit 13, the display unit 12 displays an operating condition setting screen for setting the operating conditions of the temperature adjustment system 100 and an operation state display indicating the operation state of the temperature adjustment system 100 (each temperature adjustment device 2). Display a screen (neither shown).

The control unit 13 is an example of an “integrated control unit”, and adjusts the temperature of the cooling liquid Wa pressure-fed (supplied) from the temperature adjustment system 100 to the supply target X to the overall target temperature ASvs, and adjusts the temperature. The controllers 28 in the respective temperature adjustment devices 2, which will be described later, are controlled in such a manner that the pressure of the coolant Wa pressure-fed (supplied) from the system 100 to the supply target X is pressurized to the overall target pressure BSvs. Specifically, based on the sensor signal S3 output from the temperature sensor 3, the control unit 13 controls the temperature of the coolant Wa (hereinafter referred to as (also referred to as "actually measured overall temperature APvs") is specified, and each temperature adjustment device 2 (control unit 28) is operated so that the specified measured overall temperature APvs becomes the overall target temperature ASvs. In addition, the control unit 13 controls the pressure of the cooling liquid Wa pumped to the supply target X from the temperature adjustment system 100 through the feed pipe Ps based on the sensor signal S4 output from the pressure sensor 4 (hereinafter referred to as "total actual measurement pressure BPvs"), and operate each temperature adjustment device 2 (control unit 28) so that the specified overall measured pressure BPvs becomes the overall target pressure BSvs.

In this case, the control unit 13 controls the plurality of temperature adjustment devices 2 to operate differently within a range that satisfies the condition that the coolant Wa is adjusted to the overall target temperature ASvs and pressurized to the overall target pressure BSvs. While controlling each temperature adjustment device 2 in a type of control mode, based on the power consumption data Dpc output from each temperature adjustment device 2 as described later, the total power consumption per unit time by the temperature adjustment system 100 (hereinafter referred to as , simply referred to as “total power consumption”) is executed for each control mode. In addition, the control unit 13 controls each temperature adjustment device 2 in the specified control mode in which the overall power consumption is small. It should be noted that various processes executed by the control unit 13 (supply capacity specifying process 50 shown in FIG. 4, optimum control mode specifying process 60 shown in FIG. 7, optimal control mode specifying process 70 shown in FIG. 9, etc.) are specifically described. The contents will be explained in detail later. The storage unit 14 is an example of a “storage unit”, and includes an operation program of the control unit 13, power consumption data Dpc output from the temperature adjustment device 2 as described later, and data generated by the control unit 13. It stores supply capability data Dsc and the like.

The temperature adjustment device 2 is a cooling liquid supply device, which is an example of a "temperature adjustment device", and is configured to adjust the temperature of the cooling liquid Wa and pump it. Specifically, as shown in FIG. 3, the temperature adjustment device 2 includes a liquid storage tank 21, a refrigeration cycle 22, an air cooling mechanism 23, a pressure pump 24, a blower fan 25, temperature sensors 26a to 26c, a pressure sensor 27, It has a control unit 28 and a power supply unit 29, which are accommodated and packaged in a rectangular parallelepiped housing.

The liquid storage tank 21 is configured to be able to store the cooling liquid Wa to be supplied to the supply object X. As shown in FIG. In this case, in the temperature adjustment system 100 of this embodiment, which is a circulation-type cooling liquid supply system, the cooling liquid Wa recovered from the supply target X through the return pipe Pr is supplied to the supply target X. A return pipe Pr is connected to the liquid inlet of the temperature control device 2 so that the liquid can be stored in the liquid storage tank 21 as a liquid storage tank 21 .

The refrigerating cycle 22 is an example of a “regulator” and includes a compressor 31 , a condenser 32 , an expansion valve 33 and a heat exchanger (evaporator) 34 . In this refrigerating cycle 22, the refrigerant pressure-fed by the compressor 31 and condensed in the condenser 32 passes through the expansion valve 33 and is supplied into the heat exchanger 34. As will be described later, the heat exchanger 34 The temperature of the cooling liquid Wa can be adjusted (lowered) by heat exchange between the cooling liquid Wa passing through and the refrigerant. In practice, a pressure sensor for specifying the refrigerant pressure in the refrigerating cycle 22 and a temperature sensor for specifying the refrigerant temperature are provided, but illustration and description of these sensors are omitted.

The air cooling mechanism 23 is another example of the “adjustment unit” and includes a heat exchanger 41 , a heat exchanger 42 and a circulation pump 43 . This air cooling mechanism 23 is supplied to the heat exchanger 42 after the temperature of the cooling liquid Wb pumped by the circulation pump 43 is lowered by heat exchange with the atmosphere (air) in the heat exchanger 41, which will be described later. Thus, the temperature of the cooling liquid Wa can be adjusted (lowered) by heat exchange between the cooling liquid Wa and the cooling liquid Wb that are passed through the heat exchanger 42 .

The pressure-feeding pump 24 is an example of a “pressure-feeding unit”, and in this example, is configured by a variable pressure-feeding amount pump, and is connected between the liquid storage tank 21 and the heat exchanger 42 . The pressure-feeding pump 24 pressurizes the cooling liquid Wa stored in the liquid storage tank 21 under the control of the control unit 28, thereby cooling the heat exchanger 42 of the air cooling mechanism 23 and the heat exchanger 34 of the refrigerating cycle 22. It is configured to be able to pass through in this order and output to the feed pipe Ps from the liquid outlet of the temperature adjustment device 2 to be pressure-fed (supplied) to the supply target X.

The blowing fan 25 is, for example, a variable blowing amount (variable number of revolutions) fan, and is arranged downstream of the air flow path in the housing. The blowing fan 25 is a fan for introducing air into the housing for lowering the temperature of the coolant Wb by heat exchange in the heat exchanger 41 and condensing the refrigerant by heat exchange in the condenser 32. It is rotated under the control of the control unit 28 to blow (exhaust) the air inside the housing to the outside of the housing so that new air can be introduced into the housing from outside.

A single blower fan 25 blows air to both the condenser 32 of the refrigerating cycle 22 and the heat exchanger 41 of the air cooling mechanism 23 (the blowing fan 25 is shared by the refrigerating cycle 22 and the air cooling mechanism 23). Instead of the configuration of this example, it is also possible to adopt a configuration in which a blower fan for sending air to the condenser 32 and a blower fan for blowing air to the heat exchanger 41 are separately arranged to blow air respectively (not shown). ).

The temperature sensor 26a is arranged in the liquid storage tank 21, detects the temperature of the coolant Wa stored in the liquid storage tank 21, and outputs a sensor signal S26a. As an example, the temperature sensor 26b is disposed between the circulation pump 43 and the heat exchanger 42 in the air cooling mechanism 23, and the temperature of the heat exchanger 41 is lowered by heat exchange with air in the heat exchanger 41 and It detects the temperature of the pumped coolant Wb and outputs a sensor signal S26b. The temperature sensor 26c is arranged near the liquid outlet of the temperature control device 2, and the temperature is lowered by the heat exchanger 42 and/or the heat exchanger 34, and the liquid is pressure-fed from the temperature control device 2 to the supply target X. It detects the temperature of the coolant Wa and outputs a sensor signal S26c. The pressure sensor 27 is arranged near the liquid outlet of the temperature control device 2 and detects the pressure of the cooling liquid Wa pressure-fed from the temperature control device 2 to the supply object X by the pressure pump 24 to output a sensor signal S27. Output.

The control unit 28 is an example of an "individual control unit", and as will be described later, by controlling the pressure feed pump 24 according to the control of the control device 1 (control unit 13), the liquid stored in the liquid storage tank 21 is The cooling liquid Wa is passed through the heat exchanger 42 and the heat exchanger 34 in this order, and pressure-fed to the supply target X via the feed pipe Ps. Specifically, the control unit 28 specifies the pressure of the cooling liquid Wa pressure-fed from the temperature adjustment device 2 to the supply target X based on the sensor signal S27 from the pressure sensor 27, and the specified pressure is determined by the control device. 1 (control unit 13) to change the operation state (rotational speed of the electric motor) of the compressing pump 24 so as to achieve the individual target pressure specified by the controller 13).

In the following description, the individual target pressure designated by the control device 1 to the temperature adjustment device 2a is also referred to as an individual target pressure BSva, and the pressure specified based on the sensor signal S27 in the temperature adjustment device 2a is measured individually. The individual target pressure specified by the control device 1 to the temperature adjusting device 2b is also referred to as the individual target pressure BSvb, and the pressure specified based on the sensor signal S27 in the temperature adjusting device 2b is also referred to as the individual measured pressure BPvb. The individual target pressure designated by the control device 1 to the temperature adjustment device 2c is also called an individual target pressure BSvc, and the pressure specified based on the sensor signal S27 in the temperature adjustment device 2c is also called an individual measured pressure BPvc. The individual target pressure specified by the device 1 for the temperature adjustment device 2d is also called an individual target pressure BSvd, and the pressure specified by the temperature adjustment device 2d based on the sensor signal S27 is also called an individual measured pressure BPvd.

In addition, the control unit 28 controls the air cooling mechanism 23 (circulation pump 43) and the blower fan 25 according to the control of the control device 1 (control unit 13) to control the temperature of the cooling liquid Wb (that is, in the heat exchanger 42). The temperature of the cooling liquid Wa to be heat-exchanged) is adjusted. Furthermore, the control unit 28 adjusts the temperature of the coolant Wa by controlling the refrigeration cycle 22 (compressor 31 and expansion valve 33) and the blower fan 25 under the control of the control device 1 (control unit 13). Specifically, the control unit 28 specifies the temperature of the coolant Wa in the liquid storage tank 21 based on the sensor signal S26a from the temperature sensor 26a, and heat exchange based on the sensor signal S26b from the temperature sensor 26b. The temperature of the coolant Wb pumped to the vessel 42 is specified. In addition, the control unit 28 specifies the temperature of the cooling liquid Wa pressure-fed from the temperature adjustment device 2 to the supply target X based on the sensor signal S26c from the temperature sensor 26c, and the specified temperature is determined by the control device 1 (control The operation states of the refrigerating cycle 22, the air cooling mechanism 23, the blower fan 25, etc. are changed so that the individual target temperature specified by the unit 13) is achieved.

In the following description, the individual target temperature designated by the control device 1 to the temperature adjustment device 2a is also referred to as an individual target temperature ASva, and the pressure specified based on the sensor signal S26c in the temperature adjustment device 2a is measured individually. The individual target temperature designated by the control device 1 to the temperature adjusting device 2b is also referred to as the individual target temperature ASvb, and the pressure specified based on the sensor signal S26c in the temperature adjusting device 2b is also referred to as the individual measured temperature APvb. The individual target temperature designated by the control device 1 to the temperature adjustment device 2c is also called an individual target temperature ASvc, and the pressure specified based on the sensor signal S26c in the temperature adjustment device 2c is also called an individual measured temperature APvc. The individual target temperature specified by the device 1 for the temperature adjustment device 2d is also called an individual target temperature ASvd, and the pressure specified based on the sensor signal S26c in the temperature adjustment device 2d is also called an individual measured temperature APvd.

In this case, the temperature adjustment device 2 of the present example is configured such that the specified individual measured temperatures APva to APvd (hereinafter also referred to as “individual measured temperatures APv” when not distinguished) are the individual target temperatures ASva to ASvd (hereinafter referred to as “ and the specified individual measured pressures BPva to BPvd (hereinafter also referred to as "individual measured pressures BPv" when not distinguished) are the individual target pressures BSva to BSvd (hereinafter referred to as "individual measured pressures BPv" when not distinguished). A configuration is adopted in which the control unit 28 independently controls each temperature adjustment device 2 so that the target pressure BSv” is achieved. For this reason, in addition to the usage pattern in which a plurality of temperature adjustment devices 2 are connected to the feed pipe Ps and the return pipe Pr and operated like the temperature adjustment system 100 of this example, the temperature adjustment device 2 It is also possible to use one temperature control device 2 alone in a mode of use in which it is connected to the feed pipe Ps and the return pipe Pr and operated.

Further, the control unit 28 outputs power consumption data Dpc output from the power supply unit 29 to the control device 1 . The power supply unit 29 supplies power to each unit of the temperature adjustment device 2 under the control of the control unit 28, and generates power consumption data Dpc that can specify the power consumption (instantaneous value) in the temperature adjustment device 2, 28.

When using this temperature control system 100, each temperature control device 2 is installed and connected to the control device 1 as shown in FIG. Regarding the feed pipe Ps and the return pipe Pr, dedicated pipes can be newly laid when installing the temperature adjustment system 100 (pipes dedicated to the temperature adjustment system 100 are prepared), but in this example, As an example, existing feed pipes Ps and return pipes Pr laid as cooling water pipes for the supply target X are used, and description of laying of the feed pipes Ps and return pipes Pr is omitted.

In this case, in the example shown in the figure, the supply pipe length (the length of the feed pipe Ps between the liquid outlet of the temperature adjustment device 2 and the supply target X) and the return pipe length (the liquid inlet of the temperature adjustment device 2 and the supply object X) are different in each temperature adjustment device 2 . Specifically, in this example, the liquid outlet of each temperature control device 2 is connected to the feed pipe Ps so that the supply pipe length gradually increases in the order of the temperature control devices 2a, 2b, 2c, and 2d. At the same time, the liquid inlet of each temperature control device 2 is connected to the return pipe Pr so that the length of the return pipe gradually increases in the order of the temperature control devices 2a, 2b, 2c, and 2d. Moreover, as described above, the temperature sensor 3 and the pressure sensor 4 are arranged between the portion of the feeding pipe Ps to which the liquid outlet of the temperature adjusting device 2a is connected and the supply target X.

In addition, the length of the supply pipe and the length of the return pipe of each temperature control device 2 (hereinafter simply referred to as "pipe length" when not distinguished) are determined by the positional relationship between the installation location of each temperature control device 2 and the supply target X, It changes according to the positional relationship between the installation location of each temperature control device 2 and the installation location of the feed pipe Ps and the return pipe Pr. For example, the temperature adjustment device 2 installed near the supply target X has a short pipe length, and the temperature adjustment device 2 installed at a location far away from the supply target X due to insufficient installation space near the supply target X. As for the device 2, the piping length is long. In addition, in this example using the existing feed pipe Ps and return pipe Pr, the pipe length of the temperature adjustment device 2 installed near the feed pipe Ps and return pipe Pr is shortened, and the feed pipe Ps For the temperature control device 2 installed at a location greatly separated from the return pipe Pr, a long connecting pipe for connecting the liquid outlet to the feed pipe Ps and a long connecting pipe for connecting the liquid inlet to the return pipe Pr The length of the piping is increased by the length of the connecting piping required.

Next, the cooling liquid Wa (for example, antifreeze) is poured into the liquid storage tank 21 of each temperature control device 2, and the cooling liquid Wb is introduced into the flow path of the air cooling mechanism 23 of each temperature control device 2 from an inlet (not shown). (as an example, antifreeze) is poured into each. In addition, when the cooling liquid Wa is poured into each liquid storage tank 21 when the temperature adjustment system 100 is newly installed or the installation location is changed, the flow path of the cooling liquid Wa in the temperature adjustment device 2, the feed pipe Ps and the return pipe Ps It is necessary to perform a degassing operation to remove the air present in the pipe Pr and the like. Although it is necessary to carry out aeration work, since these deaeration work are publicly known, a detailed description thereof will be omitted. As described above, the cooling liquid Wa is circulated between the temperature control system 100 (each temperature control device 2 ) and the supply target X, and the cooling liquid Wb is circulated within the air cooling mechanism 23 .

Next, the process of supplying the coolant Wa to the supply object X by the temperature adjustment system 100 that has been installed will be described. First, the process of specifying the supply capacity of the coolant Wa to the supply target X of each temperature adjustment device 2 (supply capacity of a single unit) will be described.

When specifying the supply capacity of each temperature adjustment device 2, as an example, an instruction to start processing is given by operating the operation unit 11 of the control device 1 ("the predetermined second start condition is satisfied. example). At this time, the control unit 13 starts the supply capability identification process 50 shown in FIG. In this supply capability identification process 50, the control unit 13 first identifies the temperature of the cooling liquid Wa in the feed pipe Ps based on the sensor signal S3 from the temperature sensor 3 (entire measured temperature APvs) from the pressure sensor 4. Based on the pressure of the coolant Wa in the feed pipe Ps (the total measured pressure BPvs) based on the sensor signal S4, the operating state of the temperature adjustment device 2, and the power consumption data Dpc output from the temperature adjustment device 2. The overall power consumption is calculated, and the specified overall measured temperature APvs, overall measured pressure BPvs, operating state, and calculated overall power consumption are stored in the storage unit 14 (step 51).

At this point in time when none of the temperature control devices 2 are in operation, the specified overall measured temperature APvs is about the same as the ambient temperature (about the same temperature as the temperature at the installation location of the feed pipe Ps: 25 as an example). ° C.: At the temperature A0 shown in FIG. 5), the specified overall measured pressure BPvs is 0 kPa (pressure B0 shown in FIG. 6). Further, the control unit 13 specifies the overall measured temperature APvs, specifies the overall measured pressure BPvs, and determines the operation state of each temperature adjustment device 2, which is started in step 51, until it is determined in step 55 described later that the end condition is satisfied. , calculation of the total power consumption, and storage of the identified overall measured temperature APvs, overall measured pressure BPvs, operating state, and calculated total power consumption in the storage unit 14 are continuously executed.

Immediately after starting the process of step 51, the control unit 13 controls any one of the temperature adjusting devices 2 to start warm-up operation (step 52). As will be described later, in the supply capacity specifying process 50, each temperature adjustment device 2 is operated individually to generate supply capacity data Dsc that can specify the supply capacity of each temperature adjustment device 2. The order of specifying the capabilities (the order of individual operation) can be arbitrarily defined regardless of the connection positions with respect to the return pipe Pr and the feed pipe Ps. In this example, as an example, it is assumed that the temperature adjustment devices 2a, 2b, 2c, and 2d are set in advance so as to specify their supply capacities in that order. Therefore, at this point immediately after the start of the supply capacity specifying process 50, the control unit 13 controls the temperature adjusting device 2a to start warming up.

Specifically, the control unit 13 sets the temperature A1 shown in FIG. 5 (20° C. as an example) to the individual target temperature ASva, and the pressure B1 shown in FIG. 6 (50 kPa as an example) to the individual target pressure BSva. to instruct the controller 28 of the temperature adjustment device 2a to start operation. In response to this, in the temperature adjustment device 2a, the control unit 28 controls the refrigeration cycle 22 (compressor 31 and expansion valve 33) and the air cooling mechanism 23 (circulation pump 43) in accordance with instructions from the control device 1 (control unit 13). and controls the blowing fan 25 to start cooling the cooling liquid Wa, and controls the pumping pump 24 to start pumping the cooling liquid Wa.

In this case, the control unit 28 first controls the pressure-feeding pump 24 to start pressure-feeding the cooling liquid Wa from the liquid storage tank 21, and the cooling liquid Wa specified based on the sensor signal S27 from the pressure sensor 27. When the pressure reaches the individual target pressure BSva (pressure B1 in FIG. 6 in this example during warm-up operation), the pump 24 is controlled to maintain the operating state (pumping capacity) at that time. In addition, the control unit 28 operates both the refrigerating cycle 22 and the air cooling mechanism 23 in parallel with the pumping of the cooling liquid Wa by the pumping pump 24 to adjust the temperature of the cooling liquid Wa.

At this time, for example, since the outside air temperature is higher than the specified individual target temperature ASva (20° C. in this example), the air cooling mechanism 23 sets the temperature of the coolant Wb to the individual target temperature ASva or the individual target temperature ASva. When the temperature of the coolant Wa cannot be lowered to a temperature close to the individual target temperature ASva or a temperature close to the individual target temperature ASva by heat exchange with the coolant Wb in the heat exchanger 42 ), the control unit 28 reduces the rate of contribution of the air cooling mechanism 23 to the temperature adjustment of the coolant Wa by reducing the rotation speed of the circulation pump 43, and adjusts the temperature based on the sensor signal S26c from the temperature sensor 26c. The temperature of the coolant Wa output from the device 2a (individual measured temperature APva) is specified, and the refrigeration cycle 22 (compressor 31 and expansion valve 33) and the air blower are adjusted so that the specified individual measured temperature APva becomes the individual target temperature ASva. The operating state of the cooling fan 25 is appropriately changed.

Further, when the outside air temperature is lower than the specified individual target temperature ASva and the temperature of the coolant Wb in the air cooling mechanism 23 can be lowered to the individual target temperature ASva (that is, when the coolant Wb in the heat exchanger 42 and (when the temperature of the cooling liquid Wa can be lowered to the individual target temperature ASva by heat exchange), the control unit 28 increases the rotation speed of the circulation pump 43 to adjust the temperature of the cooling liquid Wa. while increasing the contribution rate of the refrigerating cycle 22 and the blower fan 25 so that the temperature of the coolant Wa specified based on the sensor signal S26c (individual measured temperature APva) becomes the individual target temperature ASva. change.

Furthermore, for example, when the outside air temperature is much higher than the designated individual target temperature ASva and the air cooling mechanism 23 cannot even lower the temperature of the coolant Wb to a temperature close to the individual target temperature ASva (that is, when the heat exchange When the temperature of the cooling liquid Wa cannot be lowered to a temperature close to the individual target temperature ASva by heat exchange with the cooling liquid Wb in the vessel 42), the control unit 28 stops the circulation pump 43 so that the air cooling mechanism 23 The temperature adjustment of the cooling liquid Wa by the sensor signal S26c is stopped, and the temperature of the cooling liquid Wa specified based on the sensor signal S26c (individual measured temperature APva) becomes the individual target temperature ASva. Change the operating state accordingly.

Further, when the outside air temperature is much lower than the specified individual target temperature ASva and the temperature of the coolant Wb can be sufficiently lowered to the individual target temperature ASva in the air cooling mechanism 23 (that is, when the heat exchanger 34 When the temperature of the cooling liquid Wa can be sufficiently lowered to the individual target temperature ASva by heat exchange with the cooling liquid Wb in the heat exchanger 42 without heat exchange with the refrigerant, the control unit 28 , the refrigeration cycle 22 (compressor 31 and expansion valve 33) is stopped, and the air cooling mechanism 23 is controlled so that the temperature of the coolant Wa (individual measured temperature APva) specified based on the sensor signal S26c becomes the individual target temperature ASva. and the operating state of the blower fan 25 is changed as appropriate.

By performing the above-described control, as shown in FIG. 5, the individual measured temperature APva of the coolant Wa output from the temperature adjustment device 2a is gradually As shown in FIG. 6, the measured individual pressure BPva of the coolant Wa output from the temperature adjustment device 2a gradually rises from time tb0 at which the warm-up start is instructed.

On the other hand, the control unit 13 determines whether or not the condition for starting the ability-specified operation, which will be described later, is satisfied after the instruction to start the warm-up operation is given in step 52 (step 53). Specifically, the control unit 13 controls the temperature of the coolant Wa specified based on the sensor signal S3 from the temperature sensor 3 (entirely measured temperature APvs) and the sensor signal S4 from the pressure sensor 4. The pressure of the coolant Wa (actually measured overall pressure BPvs) is monitored, and the measured overall temperature APvs reaches the individual target temperature ASva (20° C. in this example) specified for the temperature adjustment device 2a (control unit 28), and When the overall measured pressure BPvs reaches the individual target pressure BSva (50 kPa in this example) specified for the temperature adjustment device 2a (control section 28), it is determined that the start condition is satisfied.

Further, when the control unit 13 determines that the start condition is satisfied, the control unit 13 starts the ability specific operation (step 54). Specifically, the control unit 13 sets the temperature A2 (15° C., for example) shown in FIG. 5 as the new individual target temperature ASva, and performs control to maintain the pressure B1 (50 kPa in this example) shown in FIG. The control unit 28 of the temperature adjustment device 2a is instructed to operate in the mode. Accordingly, in the temperature adjustment device 2a, the control unit 28 controls the refrigerating cycle 22, the air cooling mechanism 23, and the blower fan 25 in accordance with the instruction from the control device 1 (control unit 13) so that the cooling liquid Wa is While cooling to the individual target temperature ASva, the pressure pump 24 is controlled to maintain the pressure of the coolant Wa.

Further, when the overall measured temperature APvs of the cooling liquid Wa specified based on the sensor signal S3 reaches the temperature A2 (15° C. in this example), the control unit 13 maintains the temperature A2 while keeping the temperature A2 as shown in FIG. 2 (for example, 300 kPa) as a new individual target pressure BSva. Accordingly, in the temperature adjustment device 2a, the control unit 28 controls the refrigerating cycle 22, the air cooling mechanism 23, and the blower fan 25 in accordance with the instruction from the control device 1 (control unit 13) so that the cooling liquid Wa is While maintaining the individual target temperature ASva, the pump 24 is controlled to increase the pressure of the coolant Wa to a new individual target pressure BSva. By performing the above-described control, as shown in FIG. 5, the individual measured temperature APva of the coolant Wa output from the temperature adjustment device 2a is gradually As shown in FIG. 6, the measured individual pressure BPva of the coolant Wa output from the temperature adjustment device 2a gradually rises from time tb1 at which the instruction to start the capacity-specific operation is given.

Further, the control unit 13 determines whether or not the condition for ending the ability-specific operation is satisfied after the instruction to start the ability-specific operation is given in step 54 (step 55). Specifically, the control unit 13 controls the overall measured temperature APvs of the coolant Wa specified based on the sensor signal S3 from the temperature sensor 3, and the coolant temperature specified based on the sensor signal S4 from the pressure sensor 4. The overall measured pressure BPvs of Wa is monitored. In addition, the control unit 13 controls the overall measured temperature APvs of the cooling liquid Wa to become the new individual target temperature ASva (15° C. in this example) specified for the temperature adjustment device 2a (control unit 28), and the cooling liquid Wa When a predetermined time has passed since the total measured pressure BPvs reached a new individual target pressure BSva (300 kPa in this example) specified for the temperature adjustment device 2a (control unit 28), Determine if the termination condition is satisfied. Further, when the control unit 13 determines that the termination condition is satisfied, the control unit 13 controls the temperature adjustment device 2a (control unit 28) to stop the operation (step 56).

Next, the control unit 13 determines the time required for the overall measured temperature APvs of the coolant Wa to reach the newly specified individual target temperature ASva from the initially specified individual target temperature ASva for the temperature adjustment device 2a, and In the meantime, the power consumption consumed by the temperature adjustment system 100 (that is, the temperature adjustment device 2a) and the overall measured pressure BPvs of the coolant Wa are newly set from the individual target pressure BSva initially specified for the temperature adjustment device 2a. The time required to reach the specified individual target pressure BSva, the amount of power consumed by the temperature adjustment system 100 (temperature adjustment device 2a) during that time, the overall measured temperature APvs and the overall measured pressure BPvs of the coolant Wa are the new individual target temperature ASva and the new individual target pressure BSva, respectively, and the power consumption consumed by the temperature adjustment system 100 (temperature adjustment device 2a) within the time during which the state is maintained after becoming the new individual target temperature ASva ( step 57).

Specifically, the control unit 13 determines that the overall target temperature ASvs of the coolant Wa is adjusted from the individual target temperature ASva (20° C. in the above example) specified for the temperature adjustment device 2a at the start of the warm-up operation to The time (time Ta from time ta1 to ta2 in the example shown in FIG. 5) required for the individual target temperature ASva (15° C. in the above example) specified at the start of the ability-specific operation is specified. In addition, the control unit 13 measures the amount of power consumed by the temperature adjustment system 100 (the temperature adjustment device 2a) during the time Ta in the example shown in FIG.

Furthermore, the control unit 13 determines that the overall measured pressure BPvs of the cooling liquid Wa is the individual target pressure BSva (50 kPa in the above example) specified at the start of the warm-up operation for the temperature adjustment device 2a. The time (time Tb between times tb1 and tb2 in the example shown in FIG. 6) required to rise to the individual target pressure BSva (300 kPa in the above example) specified at the start is specified. Further, the control unit 13 measures the amount of power consumed by the temperature adjustment system 100 (the temperature adjustment device 2a) during the time Tb in the example shown in FIG.

Furthermore, the control unit 13 determines that the overall measured temperature APvs of the coolant Wa specified based on the sensor signal S3 is the individual target temperature ASva (in the above example, , 15° C.), and the overall measured pressure BPvs of the coolant Wa specified based on the sensor signal S4 reaches the individual target pressure BSva (the above 300 kPa in the example), the temperature control system 100 (the temperature control device 2a ) to measure the amount of power consumed by

Subsequently, the control unit 13 generates the supply capability data Dsc that can specify the supply capability of the coolant Wa to the supply object X of the temperature adjustment device 2a (step 58). Specifically, the control unit 13 changes the initially designated individual target temperature ASva (20° C.), the newly designated individual target temperature ASva (15° C.), and the overall measured temperature APvs from the initial individual target temperature ASva to the new individual target temperature ASva. Unit time for temperature adjustment (cooling) of the coolant Wa by the temperature adjustment device 2a based on the time (time Ta) required to reach the individual target temperature ASva and the power consumption during that time (time Ta) regulating capacity (efficiency) per unit and the total power consumption in performing such temperature regulation (cooling) (at this point in time when only the temperature regulation device 2a is operating, the individual Power consumption: hereinafter, when the overall power consumption of the temperature control system 100 is the individual power consumption of any temperature control device 2, these are simply referred to as “power consumption” without distinction) are calculated respectively. do.

In addition, the control unit 13 changes the initially specified individual target pressure BSva (50 kPa), the newly specified individual target pressure BSva (300 kPa), and the overall measured pressure BPvs from the initial individual target pressure BSva to the new individual target pressure BSva. Based on the time (time Tb) required to reach the temperature and the amount of power consumption during that time (time Tb), the ability to increase the pumped amount per unit time (efficiency ) and the amount of power consumption when performing such an increase in the amount of pumping.

Further, the control unit 13 controls the temperature adjusting device 2a based on the newly specified individual target temperature ASva (15° C.) and the power consumption during the time (time Tc) during which the individual target pressure BSva (300 kPa) is maintained. , the power consumption when continuing the process of pumping the coolant Wa at the individual target temperature ASva (15° C.) at the individual target pressure BSva (300 kPa) is calculated. Subsequently, the control unit 13 records the calculation result as information about the temperature adjustment device 2a to generate the supply capability data Dsc, and causes the storage unit 14 to store the data.

Next, the control unit 13 determines whether or not there is another temperature adjustment device 2 that has not completed the generation of the supply capacity data Dsc (step 59). At this time, since the supply capacity data Dsc for the temperature adjusting devices 2b to 2d are not completed, the control unit 13 returns to the above-described step 51, Identification, identification of the overall measured pressure BPvs of the coolant Wa in the feed pipe Ps, identification of the operating state of the temperature adjustment device 2, and calculation of the overall power consumption are performed, and the identified overall measured temperature APvs and overall measured pressure BPvs Then, a process of storing the operating state and the calculated total power consumption in the storage unit 14 is started.

Further, the control unit 13 similarly executes the above-described processes of steps 52 to 58 executed for the temperature adjustment device 2a for the temperature adjustment device 2b. Further, when the control unit 13 determines in step 59 that there is no other temperature adjustment device 2 for which generation of the supply capability data Dsc has not been completed (the supply capability data Dsc for all the temperature adjustment devices 2a to 2d is generation is completed), this supply capacity identification process 50 ends. Thus, the generation of the supply capability data Dsc for each temperature adjustment device 2 is completed, and preparations for supplying the coolant Wa to the supply target X by the temperature adjustment system 100 (each temperature adjustment device 2) are completed. In this example, each of the processes of steps 54 to 58, which is executed while each temperature adjustment device 2 is individually operated, is performed by "operating each temperature adjustment device individually and sequentially to This corresponds to "second specifying process for specifying individual power consumption per hour".

In this case, at the time of execution of the above-described supply capacity identification process 50, for example, the temperature adjustment device 2 installed near a heat-generating device, the temperature adjustment device 2 installed in a sunny or poorly ventilated place, and the condition If the temperature adjustment device 2 is bad (the movable parts are worn out, etc.), the processing efficiency of adjusting (lowering) the temperature of the cooling liquid Wa by the refrigeration cycle 22 or the air cooling mechanism 23 is reduced, so the control device 1 (control The time required to adjust the coolant Wa to the individual target temperature ASv in accordance with the instruction from the unit 13) increases, and the individual power consumption required to complete such temperature adjustment (cooling) also increases. Further, in such a temperature adjustment device 2, the individual power consumption required to maintain the coolant Wa at the individual target temperature ASv according to the instruction from the control device 1 (control unit 13) also increases.

On the other hand, in the temperature adjustment device 2, which is installed in a well-ventilated shade sufficiently away from the heat-generating equipment and in good condition, the temperature of the coolant Wa is adjusted (reduced) by the refrigeration cycle 22 and the air cooling mechanism 23. Since the processing efficiency is improved, the time required to adjust the coolant Wa to the individual target temperature ASv according to the instruction from the control device 1 (control unit 13) is shortened, and such temperature adjustment (cooling) It also reduces the individual power consumption required to complete the Further, in such a temperature adjustment device 2, the individual power consumption required to maintain the temperature of the coolant Wa at the individual target temperature ASv according to the instruction from the control device 1 (control unit 13) is also reduced.

In addition, the temperature control device 2 with a long feeding pipe Ps connected thereto, the diameter of the connected feeding pipe Ps being small, or the existence of a large number of joints or the like may cause an effective disconnection in the pipe. In the temperature adjustment device 2 having a small area and the temperature adjustment device 2 installed at a lower position than the supply target X, the processing efficiency of pressure-feeding the cooling liquid Wa by the pressure-feeding pump 24 is reduced. 13), the time required for the coolant Wa to be pumped at the individual target pressure BSv becomes longer, and the individual power consumption required until the pump can be pumped at the individual target pressure BSv. quantity will also increase. Further, in such a temperature adjustment device 2, the individual power consumption required to maintain the pressure of the coolant Wa at the individual target pressure BSv according to the instruction from the control device 1 (control section 13) also increases.

In addition, in the temperature adjustment device 2 with low pumping efficiency of the cooling liquid Wa, the rotation speed of the pumping pump 24 is sufficiently increased in order to achieve the individual target pressure BSv designated by the control device 1 (control unit 13). As a result of the necessity, the amount of heat generated from the pumping pump 24 tends to increase when the coolant Wa is pumped. Therefore, in the temperature control device 2 in which the pumping efficiency of the cooling liquid Wa is low, the temperature of the cooling liquid Wa rises when passing through the pumping pump 24 . Therefore, it is necessary to sufficiently adjust (cool) the temperature of the cooling liquid Wa in the refrigerating cycle 22 and the air cooling mechanism 23 by this temperature rise, and as a result, the temperature of the cooling liquid Wa is adjusted and maintained at the individual target temperature ASv. The individual power consumption required to do so will also increase further.

On the other hand, the pipe length of the connected feed pipe Ps is short, the effective cross-sectional area in the pipe of the connected feed pipe Ps is sufficiently wide, and the height and the supply target are about the same as the supply target X. In the temperature adjustment device 2 installed at a higher place than X, the processing efficiency of pumping the cooling liquid Wa by the pumping pump 24 is improved, so the cooling liquid Wa is individually pumped according to the instruction from the control device 1 (control unit 13). The time required for pumping at the target pressure BSv is shortened, and the individual power consumption required for pumping at the individual target pressure BSv is reduced. Further, in such a temperature adjustment device 2, the individual power consumption required to maintain the pressure of the coolant Wa at the individual target pressure BSv according to the instruction from the control device 1 (control section 13) is also reduced.

In addition, in the temperature adjustment device 2 having a high pumping efficiency of the cooling liquid Wa, the rotation speed of the pumping pump 24 is increased more than necessary in order to achieve the individual target pressure BSv specified by the control device 1 (control unit 13). Therefore, the amount of heat generated from the pumping pump 24 tends to be small when the coolant Wa is pumped. Therefore, in the temperature control device 2 with high pumping efficiency of the cooling liquid Wa, the amount of temperature rise of the cooling liquid Wa when passing through the pumping pump 24 is small. Therefore, the temperature adjustment (cooling) of the coolant Wa by the refrigerating cycle 22 and the air-cooling mechanism 23 does not cause a large increase in individual power consumption.

In this case, the installation environment of each temperature adjustment device 2 constituting the temperature adjustment system 100 and the laying environment of the feed pipe Ps are different for each user. Further, when the temperature adjustment system 100 is configured by newly installing each temperature adjustment device 2, there is no big problem. When configured, there is a possibility that the condition of the existing temperature control device 2 and the condition of the added temperature control device 2 will be different. Therefore, by performing a process such as the above-described supply capacity specifying process 50 to specify the processing capacity of each temperature adjustment device 2 individually, during the actual operation described below (when the four temperature adjustment devices 2 are in operation) ), it is possible to suitably adjust the individual supply capacities.

Next, the process of supplying the cooling liquid Wa to the supply target X using the four temperature adjusting devices 2a to 2d will be described.

In a state where the acquisition of the supply capacity data Dsc for each temperature adjustment device 2 is completed as described above, the control device 1 controls each temperature adjustment device according to the overall target temperature ASvs and overall target pressure BSvs specified by the user. 2. Specifically, as an example, when 15° C. is specified as the overall target temperature ASvs and 300 kPa is specified as the overall target pressure BSvs by a switch operation on the operation unit 11 of the control device 1 (“predetermined "When at least one of a new target temperature and a new target pressure is designated" which is an example of "when the first start condition is satisfied"), the control unit 13 detects the sensor from the temperature sensor 3 The conditions are that the overall measured temperature APvs specified based on the signal S3 matches the overall target temperature ASvs and the overall measured pressure BPvs specified based on the sensor signal S4 from the pressure sensor 4 matches the overall target pressure BSvs. Control each temperature adjustment device 2 in various control modes within a range that satisfies the above, specify a control mode with low overall power consumption, and control and supply each temperature adjustment device 2 (control unit 28) in the specified control mode The cooling liquid Wa is supplied to each of the targets X.

Note that in the temperature adjustment system 100 (control device 1) of the present example, each temperature adjustment device 2 is controlled by specifying a control mode in which the overall power consumption is low under the condition that the overall measured temperature APvs matches the overall target temperature ASvs. (control processing related to temperature adjustment), and processing (pressure adjustment control processing) are executed in parallel. Hereinafter, in order to facilitate understanding of the control of each temperature adjustment device 2 by the control device 1 (control unit 13), first, an optimum control mode identification process 60 (see FIG. 7), which is an example of control processing related to temperature adjustment, will be described. Next, an optimum control mode specifying process 70 (see FIG. 9), which is an example of control process related to pressure adjustment, will be described.

When the user designates the overall target temperature ASvs as described above, the control unit 13 starts the optimum control mode specifying process 60 shown in FIG. In this optimum control mode identification process 60, the control unit 13 first identifies the temperature of the coolant Wa in the feed pipe Ps based on the sensor signal S3 from the temperature sensor 3 (entirely measured temperature APvs). and calculates the overall power consumption based on the power consumption data Dpc output from the temperature adjustment device 2, and the specified overall actual measured temperature APvs and the operating state are combined with the calculated overall power consumption. It is stored in the storage unit 14 (step 61). Note that the control unit 13 specifies the overall measured temperature APvs, specifies the operating state of each temperature adjustment device 2, and specifies the operating state of each temperature adjustment device 2 and the overall temperature starting in step 61 until the control in the optimum control mode is executed in step 65, which will be described later. Calculation of power consumption, and processing of storing the specified overall measured temperature APvs, the operating state, and the calculated overall power consumption in the storage unit 14 are continuously executed.

Next, as shown in FIG. 8(a), the control unit 13 sets the individual target temperature ASv (15° C. in this example) that is the same as the specified overall target temperature ASvs to each temperature adjustment device 2 in a control manner. (control unit 28) to adjust the temperature of the coolant Wa (step 62). At this time, in each temperature adjustment device 2, the control unit 28 specifies the individual measured temperature APv of the cooling liquid Wa output to the feed pipe Ps based on the sensor signal S26c from the temperature sensor 26c, and the specified individual Refrigerating cycle 22 (compressor 31 and expansion valve 33), air cooling mechanism 23 (circulating pump 43) and The temperature of the coolant Wa is adjusted (cooled) by controlling the blower fan 25 .

In practice, the pressure-feeding pump 24 is controlled according to the individual target pressure BSv specified by the control device 1 (control unit 13) as described above. do. The control for changing the operating states of the refrigerating cycle 22, the air cooling mechanism 23, and the blower fan 25 according to the difference in the outside air temperature and the difference in the condition of each part is the same as the control described in the supply capacity specifying process 50 described above. Since it is the same as the procedure, detailed description is omitted.

After the control device 1 designates the individual target temperature ASv for the temperature adjustment device 2 by executing the temperature adjustment corresponding to the individual target temperature ASv designated as described above in each temperature adjustment device 2, After a while, as shown in FIG. 2(a), the overall measured temperature APvs of the cooling liquid Wa output from each temperature control device 2 to the feed pipe Ps and pressure-fed to the supply target X reaches the overall target temperature ASvs. will be in a state consistent with

Next, the control unit 13 controls each temperature adjustment device 2 in a control mode that specifies an individual target temperature ASv higher than the specified overall target temperature ASvs for the temperature adjustment devices 2 selected according to a predetermined selection criterion. (control unit 28) to adjust the temperature of the coolant Wa (step 63). In this case, in the temperature adjustment system 100 (control device 1) of the present example, in this step 63, the criterion that "the amount of power consumption during the temperature adjustment (cooling) of the cooling liquid Wa is large" is set to "predetermined selection One of the temperature adjusting devices 2a to 2d is selected as a reference, and the individual target temperature ASv specified for the selected temperature adjusting device 2 is set to the overall target temperature specified by the user. Each temperature adjustment device 2 is controlled in a control mode in which the temperature is higher than ASvs.

Specifically, the control unit 13 maintains a state in which the individual measured temperature APv and the individual target temperature ASv are matched based on the supply capacity data Dsc for each temperature adjustment device 2 generated in the supply capacity identification process 50 described above. The temperature adjustment device 2 that consumes the most power at the time is specified. At this time, as an example, when the power consumption of the temperature adjustment device 2d is the highest, the control unit 13 sets the individual target temperature ASvd specified for the temperature adjustment device 2d as shown in FIG. is set to a temperature higher than the overall target temperature ASvs, and each of the temperature adjusting devices 2a to 2c is controlled in a control mode that designates the same temperature as the overall target temperature ASvs.

In such a control mode, the operation rate of the refrigerating cycle 22, the air cooling mechanism 23, the blower fan 25, etc. is lower than when the individual target temperature ASvd, which is the same as the overall target temperature ASvs, is specified in the temperature adjustment device 2d. Therefore, the overall power consumption of the temperature adjustment system 100 is reduced by the amount of reduction in the individual power consumption of the temperature adjustment device 2d. However, when the individual measured temperature APvd of the coolant Wa output from the temperature adjustment device 2d to the feed pipe Ps becomes an individual target temperature ASvd higher than the overall target temperature ASvs, the sensor signal Overall measured temperature APvs specified based on S3 is slightly higher than overall target temperature ASvs.

Therefore, in order to compensate for the increase in the individual measured temperature APvd of the coolant Wa from the temperature adjustment device 2d, the control unit 13 sets the temperature adjustment device 2d to a temperature higher than the overall target temperature ASvs, as shown in FIG. 8(c). A control mode in which the individual target temperatures ASva to ASvc specified for the temperature adjustment devices 2a to 2c are slightly lower than the overall target temperature ASvs while maintaining a state in which a high individual target temperature ASvd is specified ("each temperature adjustment Each temperature control device 2 is controlled in an example of "control mode in which the operating state of the control unit in at least one of the devices is different from that of the other temperature control devices").

Although detailed description is omitted, the control unit 13 appropriately adjusts the degree to which the individual target temperatures ASva to ASvc are slightly lower than the overall target temperature ASvs based on the overall target temperature ASvs. As a result, when an individual target temperature ASv as shown in FIG. The overall measured temperature APvs of the cooling liquid Wa that is output to the pipe Ps and pressure-fed to the supply target X is brought into a state of matching with the overall target temperature ASvs.

Subsequently, the control unit 13 specifies the overall power consumption when controlled in the control mode of step 62 and the overall power consumption when controlled in the control mode of step 63 ("first specified process"), and it is determined whether or not the change in the control mode has reduced the overall power consumption (step 64).

At this time, when the overall power consumption does not decrease due to the change in the control mode, that is, when each temperature adjustment device 2 is controlled in a control mode that designates the same individual target temperature ASv as the overall target temperature ASvs. When the total power consumption is less in the second mode or when there is no change in the total power consumption before and after changing the control mode, the control unit 13 changes the control mode immediately before step 63 (in this example, each temperature Each temperature adjustment device 2 is operated in a control mode in which the same individual target temperature ASv as the overall target temperature ASvs is specified for the adjustment device 2 ("a control mode in which the total power consumption specified by the first specifying process is small to control the individual control units respectively": step 65).

In addition, the control unit 13 controls the individual target temperature ASv (control mode for each temperature adjustment device 2) specified in step 62, and the total power consumption when each temperature adjustment device 2 operates according to the individual target temperature ASv, Also, the overall target temperature ASvs specified at that time, the individual target temperature ASv (control mode for each temperature adjusting device 2) specified in step 63, and each temperature adjusting device 2 operate according to the individual target temperature ASv. The overall power consumption and the overall target temperature ASvs specified at that time are recorded to generate power consumption data Dpc (an example of "power consumption data"), and the generated power consumption data Dpc is recorded. It is stored in the storage unit 14 (an example of "power consumption learning process": step 66), and this optimum control mode specifying process 60 is terminated.

On the other hand, when the overall power consumption is reduced by changing the control mode, that is, an individual target temperature ASvd higher than the overall target temperature ASvs is specified for the temperature adjustment device 2d, and the temperature adjustment devices 2a to 2c When the overall power consumption is less when controlled in a control mode that specifies individual target temperatures ASva to ASvc that are slightly lower than the overall target temperature ASvs, the control unit 13 directs the temperature adjustment device 2d to the overall target temperature. An individual target temperature ASvd higher than the temperature ASvs is specified, and for the temperature adjusting device 2 selected according to a predetermined selection criterion from among the temperature adjusting devices 2a to 2c, the temperature adjusting device 2 is higher than the specified overall target temperature ASvs Each temperature adjustment device 2 (control unit 28) is controlled in a control mode that designates a higher individual target temperature ASv to adjust the temperature of the coolant Wa (step 67).

In this case, in the temperature adjustment system 100 (control device 1) of the present example, even in this step 67, the reference that "the amount of power consumption during temperature adjustment (cooling) of the cooling liquid Wa is large" is set to "predetermined One of the temperature adjusting devices 2a to 2c is selected as a selection criterion, and the individual target temperature ASv specified for the selected temperature adjusting device 2 is set to the overall target specified by the user. Each temperature adjustment device 2 is controlled in a control manner to set the temperature higher than the temperature ASvs.

Specifically, the control unit 13 has already specified an individual target temperature ASvd higher than the overall target temperature ASvs based on the supply capacity data Dsc for each temperature adjustment device 2 generated in the supply capacity specifying process 50 described above. Among the temperature control devices 2 other than the temperature control device 2d, the temperature control device 2 that consumes the most power when maintaining the state in which the individual measured temperature APv matches the individual target temperature ASv is specified. At this time, as an example, when the power consumption of the temperature adjustment device 2c is the highest, the control unit 13 sets the individual target temperature ASvd specified for the temperature adjustment device 2d as shown in FIG. is the same as the individual target temperature ASvd specified in step 63, and the individual target temperature ASvc specified for the temperature adjustment device 2c is lower than the individual target temperature ASvd and higher than the overall target temperature ASvs, and temperature adjustment As for the devices 2a and 2b, each temperature adjusting device 2 is controlled in a control mode that specifies the same temperatures as the individual target temperatures ASva and ASvb specified in step 63. FIG.

In such a control mode, the operation rate of the refrigerating cycle 22, the air cooling mechanism 23, the blower fan 25, etc. is lower than when the individual target temperature ASvd, which is the same as the overall target temperature ASvs, is specified in the temperature adjustment device 2d. The operation rate of the refrigerating cycle 22, the air cooling mechanism 23, the blower fan 25, etc. is lower than when the state is maintained and the individual target temperature ASvc, which is the same as the overall target temperature ASvs, is designated in the temperature adjustment device 2c as well. Therefore, the overall power consumption of the temperature adjustment system 100 is reduced compared to the operation in the control mode in step 63 by the amount corresponding to the reduction in the individual power consumption of the temperature adjustment device 2c. However, when the individual measured temperature APvc of the coolant Wa output from the temperature adjustment device 2c to the feed pipe Ps becomes an individual target temperature ASvc higher than the overall target temperature ASvs, the sensor signal Overall measured temperature APvs specified based on S3 is slightly higher than overall target temperature ASvs.

Therefore, in order to compensate for the increase in the individual measured temperature APvc of the coolant Wa from the temperature adjustment device 2c, the control unit 13 sets the temperature adjustment devices 2c and 2d to the overall target temperature as shown in FIG. 8(e). Control to make the individual target temperatures ASva and ASvb specified for the temperature control devices 2a and 2b sufficiently lower than the overall target temperature ASvs while maintaining the state in which the individual target temperatures ASvc and ASvd higher than ASvs are respectively specified. Each temperature control device 2 is controlled in a mode (another example of "a control mode in which the operating state of the control unit in at least one of the temperature control devices is different from that of the other temperature control devices"). As a result, when an individual target temperature ASv as shown in FIG. The overall measured temperature APvs of the cooling liquid Wa that is output to the pipe Ps and pressure-fed to the supply target X is brought into a state of matching with the overall target temperature ASvs.

Subsequently, the control unit 13 specifies the overall power consumption when controlled in the control mode of step 63 and the overall power consumption when controlled in the control mode of step 67 ("first specified (another example of the process), it is determined whether or not the change in the control mode has reduced the total power consumption (step 68).

At this time, if the overall power consumption does not decrease by changing the control mode, the control unit 13 changes the control mode immediately before step 67 (in this example, the individual target temperatures ASva to ASvc to the overall target temperature ASvs). Each temperature adjustment device 2 is operated in the control mode of step 63 in which the temperature is set slightly lower and the individual target temperature ASvd is set to a temperature higher than the overall target temperature ASvs ("total power consumption specified by the first specifying process It is another example of the process of "controlling each individual control unit in a control mode with a small amount of individual power consumption", and the individual power consumption Control each individual control unit in a control mode in which the amount of adjustment of the temperature of the heat transfer liquid by the temperature adjustment device with a large amount is smaller": step 65).

In addition, the control unit 13 controls the individual target temperature ASv (control mode for each temperature adjustment device 2) specified in step 62, and the total power consumption when each temperature adjustment device 2 operates according to the individual target temperature ASv, Also, the overall target temperature ASvs specified at that time, the individual target temperature ASv (control mode for each temperature adjusting device 2) specified in step 63, and each temperature adjusting device 2 operate according to the individual target temperature ASv. and the overall target temperature ASvs specified at that time, the individual target temperature ASv specified in step 67 (control mode for each temperature adjustment device 2), and its individual target temperature ASv The overall power consumption and the overall target temperature ASvs specified at that time are recorded to generate power consumption data Dpc when each temperature adjustment device 2 operates according to the above, and the generated power consumption data Dpc is stored. It is stored in the unit 14 (another example of the "power consumption learning process": step 66), and this optimum control mode specifying process 60 ends.

On the other hand, when the overall power consumption decreases due to a change in the control mode, the control unit 13 designates individual target temperatures ASvc and ASvd higher than the overall target temperature ASvs for the temperature adjusting devices 2c and 2d, and further, Each temperature adjustment is performed in a control mode that specifies an individual target temperature ASv higher than the specified overall target temperature ASvs for the temperature adjustment device 2 selected according to a predetermined selection criterion from among the temperature adjustment devices 2a and 2b. The device 2 (control unit 28) is controlled to adjust the temperature of the coolant Wa (step 67). Since each process after step 67 is the same as the above-described process, a detailed description thereof will be omitted.

In this way, the control unit 13 of the control device 1 determines that the operating states of the refrigeration cycle 22, the air cooling mechanism 23, and the blower fan 25 in at least one of the temperature adjustment devices 2 are different from those of the other temperature adjustment devices 2. executing a "first identification process" for sequentially controlling the control unit 28 of each temperature adjustment device 2 in a plurality of types of control modes to specify the total power consumption by the temperature adjustment system 100 for each control mode, By executing the optimum control mode specifying process 60 for controlling the control unit 28 of each temperature adjustment device 2 in the specified control mode with the lowest overall power consumption, the cooling liquid at the overall target temperature ASvs specified by the user It is possible to sufficiently reduce the overall power consumption of the temperature adjustment system 100 while reliably supplying Wa to the supply target X.

Although the optimum control mode identification process 60 has been described as an example of a process for identifying a control mode with a low overall power consumption, instead of the "predetermined selection criteria" in the optimum control mode identification process 60 (or , in addition to such selection criteria), any one of the temperature adjustment devices 2a to 2d is selected with the criterion of "low power consumption during temperature adjustment (cooling) of the coolant Wa" as the "selection criteria". A temperature control device 2 is selected, and each temperature control device 2 is controlled in a control mode in which an individual target temperature ASv specified for the selected temperature control device 2 is lower than the overall target temperature ASvs specified by the user. can be controlled individually. By controlling the control unit 28 of each temperature adjustment device 2 in such a control manner, the temperature of the cooling liquid Wa can be lowered below the overall target temperature ASvs by the temperature adjustment device 2 with a small individual power consumption. Since the individual target temperature ASv of the other temperature adjustment devices 2 can be set to a temperature higher than the overall target temperature ASvs, the individual power consumption of the temperature adjustment devices 2 operated at the individual target temperature ASv higher than the overall target temperature ASvs can be reduced, and as a result, the overall power consumption of the temperature adjustment system 100 can be reduced.

On the other hand, as described above, in the control device 1 of the present embodiment, the control processing related to pressure adjustment is executed in parallel with the control processing related to the temperature adjustment by the control device 1 . Specifically, when the user designates the overall target pressure BSvs as described above, the control unit 13 starts the optimum control mode identifying process 70 shown in FIG. In this optimum control mode identification process 70, the control unit 13 first identifies the pressure of the cooling liquid Wa in the feed pipe Ps based on the sensor signal S4 from the pressure sensor 4 (entirely measured pressure BPvs). and calculates the total power consumption based on the power consumption data Dpc output from the temperature adjustment device 2, and the specified overall measured pressure BPvs and the operating state, and the calculated total power consumption It is stored in the storage unit 14 (step 71). Note that the control unit 13 specifies the overall measured pressure BPvs, specifies the operating state of each temperature adjustment device 2, and specifies the overall pressure BPvs, which is started in step 71, and the overall The processing of calculating the power consumption, and storing the specified overall measured pressure BPvs and operating state, and the calculated overall power consumption in the storage unit 14 is continuously executed.

Next, as shown in FIG. 10(a), the control unit 13 controls each temperature adjustment device 2 ( The controller 28) is controlled to adjust the pressure of the coolant Wa (step 72). At this time, in each temperature adjustment device 2, the control unit 28 specifies the individual measured pressure BPv of the cooling liquid Wa output to the feed pipe Ps based on the sensor signal S27 from the pressure sensor 27, and the specified individual The pressure pump 24 is controlled to adjust the pressure of the coolant Wa so that the measured pressure BPv and the individual target pressure BSv designated by the control device 1 (control unit 13) match. Regarding the control for changing the operating state of the pressure pump 24 according to the difference in pipe length and effective cross-sectional area in the pipe, the difference in the height difference of the installation location, and the difference in the condition of each part, the above-mentioned supply capacity specifying process 50 Since it is the same as the control procedure described in , detailed description will be omitted.

After the control device 1 designates the individual target pressure BSv for the temperature regulation device 2 by executing the pressure adjustment corresponding to the designated individual target pressure BSv in each temperature regulation device 2 as described above, After a while, as shown in FIG. 2(a), the total measured pressure BPvs of the cooling liquid Wa output from each temperature control device 2 to the feed pipe Ps and pressure-fed to the supply object X reaches the total target pressure BSvs. will be in a state consistent with

Next, the control unit 13 controls each temperature adjustment device 2 in a control mode that specifies an individual target pressure BSv that is lower than the specified overall target pressure BSvs for the temperature adjustment device 2 selected according to a predetermined selection criterion. (control unit 28) is controlled to adjust the pressure of the coolant Wa (step 73). In this case, in the temperature adjustment system 100 (control device 1) of this example, in this step 73, the reference that "the amount of power consumption is large when adjusting the pressure of the cooling liquid Wa" is set as the "predetermined selection reference". One of the temperature adjusting devices 2a to 2d is selected, and the individual target pressure BSv specified for the selected temperature adjusting device 2 is higher than the overall target pressure BSvs specified by the user. Each temperature adjustment device 2 is controlled in a control mode for low pressure.

Specifically, the control unit 13 maintains a state in which the individual measured pressure BPv is matched with the individual target pressure BSv based on the supply capacity data Dsc for each temperature adjustment device 2 generated in the supply capacity identification process 50 described above. The temperature adjustment device 2 that consumes the most power is specified by the controller 13 at the time. At this time, as an example, when the power consumption of the temperature adjustment device 2d is the highest, the controller 13 sets the individual target pressure BSvd specified for the temperature adjustment device 2d as shown in FIG. is lower than the overall target pressure BSvs, and the temperature adjusting devices 2a to 2c are controlled in a control mode that designates the same pressure as the overall target pressure BSvs.

In such a control mode, in the temperature adjustment device 2d, since the operation rate of the pressure pump 24 and the like is lower than when the individual target pressure BSvd that is the same as the overall target pressure BSvs is specified, the individual consumption of the temperature adjustment device 2d The overall power consumption of the temperature adjustment system 100 is reduced by the amount of power reduction. However, when the individual measured pressure BPvd of the coolant Wa output from the temperature adjustment device 2d to the feed pipe Ps becomes an individual target pressure BSvd lower than the overall target pressure BSvs, the sensor signal The overall measured pressure BPvs specified based on S4 is slightly lower than the overall target pressure BSvs.

Therefore, in order to compensate for the increase in the individual measured pressure BPvd of the coolant Wa from the temperature adjustment device 2d, the control unit 13 causes the temperature adjustment device 2d to increase the total target pressure BSvs to the temperature adjustment device 2d as shown in FIG. A control mode in which the individual target pressures BSva to BSvc specified for the temperature adjustment devices 2a to 2c are slightly higher than the overall target pressure BSvs while maintaining the state in which the low individual target pressure BSvd is specified ("Each temperature adjustment Each temperature control device 2 is controlled in an example of "control mode in which the operating state of the pumping unit in at least one of the devices is different from that of the other temperature control devices").

Although detailed description is omitted, the control unit 13 appropriately adjusts the degree to which the individual target pressures BSva to BSvc are slightly higher than the overall target pressure BSvs based on the overall target pressure BSvs. As a result, when an individual target pressure BSv as shown in FIG. The overall measured pressure BPvs of the cooling liquid Wa that is output to the pipe Ps and pressure-fed to the supply target X is brought into a state of matching with the overall target pressure BSvs.

Subsequently, the control unit 13 specifies the overall power consumption when controlled in the control mode of step 72 and the overall power consumption when controlled in the control mode of step 73 ("first specified (another example of the process), it is determined whether or not the change in the control mode has reduced the overall power consumption (step 74).

At this time, when the overall power consumption does not decrease due to the change in the control mode, that is, when the individual target pressure BSv that is the same as the overall target pressure BSvs is controlled for each temperature adjustment device 2 in a control mode that designates the same individual target pressure BSv. When the total power consumption is less in the second mode or when there is no change in the total power consumption before and after changing the control mode, the control unit 13 changes the control mode immediately before step 73 (in this example, each temperature Each temperature adjustment device 2 is operated in a control mode in which the same individual target pressure BSv as the overall target pressure BSvs is specified for the adjustment device 2 ("a control mode in which the overall power consumption specified by the first specifying process is small to control the individual control units respectively": step 75).

In addition, the control unit 13 controls the individual target pressure BSv (control mode for each temperature adjustment device 2) specified in step 72, and the total power consumption when each temperature adjustment device 2 operates according to the individual target pressure BSv, Then, the overall target pressure BSvs specified at that time, the individual target pressure BSv specified in step 73 (control mode for each temperature adjustment device 2), and each temperature adjustment device 2 operate according to the individual target pressure BSv. The total power consumption and the total target pressure BSvs specified at that time are recorded to generate power consumption data Dpc (an example of "power consumption data"), and the generated power consumption data Dpc is recorded. It is stored in the storage unit 14 (an example of "power consumption learning process": step 76), and this optimum control mode specifying process 70 is terminated.

On the other hand, when the overall power consumption decreases due to a change in the control mode, that is, an individual target pressure BSvd lower than the overall target pressure BSvs is specified for the temperature adjustment device 2d, and for the temperature adjustment devices 2a to 2c When the overall power consumption is less when controlled in a control mode that specifies individual target pressures BSva to BSvc that are slightly higher than the overall target pressure BSvs, the control unit 13 directs the temperature adjustment device 2d to the overall target pressure For a temperature control device 2 that specifies an individual target pressure BSvd that is lower than the pressure BSvs and that is selected from among the temperature control devices 2a to 2c according to a predetermined selection criterion, the specified overall target pressure BSvs Each temperature adjustment device 2 (control section 28) is controlled in a control mode that designates a lower individual target pressure BSv to adjust the pressure of the coolant Wa (step 77).

In this case, in the temperature adjustment system 100 (control device 1) of the present example, in this step 77 as well, the criterion that "the amount of power consumption during pressure adjustment of the coolant Wa is large" is the "predetermined selection criterion". to select one of the temperature adjusting devices 2a to 2c as the individual target pressure BSv specified for the selected temperature adjusting device 2 from the overall target pressure BSvs specified by the user. Each temperature adjustment device 2 is controlled in a control mode in which the pressure is also low.

Specifically, the control unit 13 has already specified an individual target pressure BSvd lower than the overall target pressure BSvs based on the supply capacity data Dsc for each temperature adjustment device 2 generated in the supply capacity specifying process 50 described above. Among the temperature control devices 2 other than the temperature control device 2d, the temperature control device 2 that consumes the most power when maintaining the state in which the individual measured pressure BPv matches the individual target pressure BSv is specified. At this time, as an example, when the power consumption of the temperature adjustment device 2c is the highest, the controller 13 sets the individual target pressure BSvd specified for the temperature adjustment device 2d as shown in FIG. 10(d). is the same as the individual target pressure BSvd specified in step 73, and the individual target pressure BSvc specified for the temperature adjustment device 2c is higher than the individual target pressure BSvd and lower than the overall target pressure BSvs, and the temperature adjustment As for the devices 2a and 2b, each temperature adjusting device 2 is controlled in a control mode that specifies the same pressure as the individual target pressures BSva and BSvb specified in step 73. FIG.

In such a control mode, in the temperature adjustment device 2d, a state is maintained in which the operation rate of the pumping pump 24 and the like is lower than when the individual target pressure BSvd, which is the same as the overall target pressure BSvs, is designated, and the temperature is adjusted. In the device 2c as well, the operation rate of the pressure pump 24 and the like is lower than when the individual target pressure BSvc, which is the same as the overall target pressure BSvs, is specified. The overall power consumption of the temperature adjustment system 100 is lower than when operating in the control mode in step 73 . However, when the individual measured pressure BPvc of the coolant Wa output from the temperature adjustment device 2c to the feed pipe Ps becomes the individual target pressure BSvc lower than the overall target pressure BSvs, the sensor signal The overall measured pressure BPvs specified based on S4 is slightly lower than the overall target pressure BSvs.

Therefore, in order to compensate for the drop in the individual measured pressure BPvc of the coolant Wa from the temperature adjustment device 2c, the control unit 13 sets the temperature adjustment devices 2c and 2d to the overall target pressure as shown in FIG. 10(e). Control to make the individual target pressures BSva and BSvb specified for the temperature control devices 2a and 2b sufficiently higher than the overall target pressure BSvs while maintaining the individual target pressures BSvc and BSvd lower than BSvs, respectively. Each temperature control device 2 is controlled in a mode (another example of "a control mode in which the operating state of the pumping unit in at least one of the temperature control devices is different from that of the other temperature control devices"). As a result, when an individual target pressure BSv as shown in FIG. The overall measured pressure BPvs of the cooling liquid Wa that is output to the pipe Ps and pressure-fed to the supply target X is brought into a state of matching with the overall target pressure BSvs.

Subsequently, the control unit 13 specifies the overall power consumption when controlled in the control mode of step 73 and the overall power consumption when controlled in the control mode of step 77 ("first specified (another example of "process"), it is determined whether or not the change in the control mode has reduced the overall power consumption (step 78).

At this time, if the overall power consumption does not decrease by changing the control mode, the control unit 13 changes the control mode immediately before step 77 (in this example, the individual target pressures BSva to BSvc to the overall target pressure BSvs). the pressure is slightly higher and the individual target pressure BSvd is lower than the overall target pressure BSvs) to operate each temperature adjusting device 2 ("total power consumption specified by the first specifying process It is another example of the process of "controlling each individual control unit in a control mode with a small amount of individual power consumption", and the amount of individual power consumption is lower than the adjustment amount of the pressure of the heat transfer fluid by the temperature adjustment device with small individual power consumption. Control each individual control unit in a control mode in which the adjustment amount of the pressure of the heat transfer fluid by the temperature adjustment device having a large amount is smaller": step 75).

In addition, the control unit 13 controls the individual target pressure BSv (control mode for each temperature adjustment device 2) specified in step 72, and the total power consumption when each temperature adjustment device 2 operates according to the individual target pressure BSv, Then, the overall target pressure BSvs specified at that time, the individual target pressure BSv specified in step 73 (control mode for each temperature adjustment device 2), and each temperature adjustment device 2 operate according to the individual target pressure BSv. and the overall target pressure BSvs specified at that time, the individual target pressure BSv specified in step 77 (control mode for each temperature adjustment device 2), and its individual target pressure BSv The total power consumption and the total target pressure BSvs specified at that time are recorded to generate power consumption data Dpc, and the generated power consumption data Dpc is stored. It stores it in the unit 14 (another example of "power consumption learning process": step 76), and ends this optimum control mode specifying process 70. FIG.

On the other hand, when the overall power consumption decreases due to a change in the control mode, the control unit 13 designates individual target pressures BSvc, BSvd lower than the overall target pressure BSvs for the temperature adjustment devices 2c, 2d, and further, Each temperature adjustment in a control mode that specifies an individual target pressure BSv that is lower than the specified overall target pressure BSvs for the temperature adjustment device 2 selected according to a predetermined selection criterion from among the temperature adjustment devices 2a, 2b. The device 2 (control section 28) is controlled to adjust the pressure of the coolant Wa (step 77). It should be noted that each processing after this step 77 is the same as the above-described processing, so a detailed description thereof will be omitted.

In this way, the control unit 13 of the control device 1 controls each temperature in a plurality of types of control modes in which the operation state of the pressure pump 24 in at least one of the temperature adjustment devices 2 is different from that of the other temperature adjustment devices 2 . The control unit 28 of the adjustment device 2 is sequentially controlled to perform a "first specific process" for specifying the overall power consumption by the temperature adjustment system 100 for each control mode, and the specified overall power consumption is the smallest. By executing the optimum control mode specifying process 70 for controlling the control unit 28 of each temperature adjustment device 2 in the control mode, the cooling liquid Wa is reliably supplied to the supply object X at the overall target pressure BSvs specified by the user. , the overall power consumption of the temperature adjustment system 100 can be sufficiently reduced.

Although the optimum control mode identification process 70 has been described as an example of a process for identifying a control mode with a low overall power consumption, instead of the "predetermined selection criteria" in the optimum control mode identification process 70 (or , in addition to such a selection criterion), any one of the temperature regulating devices 2a to 2d with the criterion of ``low power consumption when adjusting the pressure of the coolant Wa'' as the ``selection criterion''. 2 is selected, and each temperature adjustment device 2 is controlled in a control mode in which the individual target pressure BSv specified for the selected temperature adjustment device 2 is higher than the overall target pressure BSvs specified by the user. You can also By controlling the control unit 28 of each temperature adjustment device 2 in such a control mode, the pressure of the coolant Wa is raised above the overall target pressure BSvs by the temperature adjustment device 2 with a small individual power consumption. Since the individual target pressure BSv of the other temperature adjustment devices 2 can be set to a pressure lower than the overall target pressure BSvs, the individual power consumption of the temperature adjustment devices 2 operated at the individual target pressure BSv lower than the overall target pressure BSvs can be reduced, and as a result, the overall power consumption of the temperature adjustment system 100 can be reduced.

When the individual target pressure BSv specified for each temperature adjustment device 2 is increased in the same manner as when the supply capacity specifying process 50 described above is executed, the cooling liquid Wa temperature tends to rise. Therefore, the execution of the optimum control mode identification process 70 causes an increase in the individual measured temperature APv of the coolant Wa due to an increase in the operation rate of the pressure feed pump 24 of any temperature adjustment device 2, or an increase in the temperature adjustment When the individually measured temperature APv of the cooling liquid Wa decreases due to a decrease in the operation rate of the pressure pump 24 of the device 2, the temperature change caused by this pressure change is taken into account and specified for each temperature adjustment device 2. The individual target temperature ASv is finely adjusted.

Also, as in the above example, when antifreeze is used as the cooling liquid Wa (heat transfer fluid), the expansion coefficient of the antifreeze is higher than that of water, so the amount of change in volume due to temperature changes is large. Therefore, when the antifreeze liquid is used as the cooling liquid Wa, when the individual measured temperature APv of the cooling liquid Wa in any of the temperature adjustment devices 2 changes significantly due to the execution of the optimum control mode specifying process 60, the temperature change The individual target pressure BSv designated for each temperature adjusting device 2 is finely adjusted in consideration of the pressure change according to the accompanying change in volume.

On the other hand, as described above, each temperature adjustment device 2 is operated in a state in which the coolant Wa having the same overall measured pressure BPvs as the overall target pressure BSvs and the overall measured temperature APvs as the overall target temperature ASvs is supplied to the supply target X. Even if it is operated, the amount of cooling liquid Wa required in the supply target X may change greatly, and the overall measured pressure BPvs may change greatly. When such a change occurs, in the control device 1 in the temperature adjustment system 100 of the present example, the control unit 13 assumes that the "first start condition" is satisfied, and the optimum control mode identification process 60 and Optimal control mode specifying processing 70 (first specifying processing) is executed to control each temperature adjustment device 2 in the newly specified optimal control mode (control mode in which the overall power consumption is low).

In this case, in order to maintain a state in which the total target temperature ASvs specified by the user and the total actual measured temperature APvs match and the total target pressure BSvs and the total actual measured pressure BPvs match, the individual target temperature ASv and the individual target pressure When each temperature adjustment device 2 is controlled in a control mode in which BSv is changed to various values, the processing of step 66 (power consumption learning processing) in the optimum control mode identification process 60 or the step 76 in the optimal control mode identification process 70 In the process (power consumption learning process), the overall power consumption corresponding to various control modes (various individual target temperatures ASv and individual target pressures BSv) is calculated based on the overall target temperature ASvs specified at that time and the overall measured temperature. It will be recorded in the power consumption data Dpc in association with APvs.

Also, a new overall target temperature ASvs and a new overall target pressure BSvs may be specified (the specified overall target temperature ASvs and overall target pressure BSvs may be changed) during operation of the temperature adjustment system 100. (Another example of "when at least one of a new target temperature and a new target pressure is specified"). At this time, in the control device 1 in the temperature adjustment system 100 of the present example, the control unit 13 assumes that the "first start condition" is satisfied, and performs the optimum control mode identification process 60 and the optimum control mode identification process 70 described above. (First specified process) is executed, and each temperature adjustment device 2 is controlled in the newly specified optimal control mode (control mode in which the operating state in which the overall power consumption is low).

In this case, each temperature adjustment device 2 is controlled in such a manner that the individual target temperature ASv and the individual target pressure BSv are changed to various values corresponding to the new overall target temperature ASvs and the new overall target pressure BSvs designated by the user. is controlled, various control modes ( The overall power consumption corresponding to various individual target temperatures ASv and individual target pressures BSv) is recorded in the power consumption data Dpc in association with the newly specified overall target temperature ASvs and overall measured temperature APvs. .

Therefore, in the temperature adjustment system 100 (control device 1) of the present example, the control unit 13 designates any overall target temperature ASvs or overall target pressure BSvs in a state where the power consumption data Dpc is stored in the storage unit 14. and the control mode (individual target temperature ASv and individual target pressure BSv) associated with the specified overall target temperature ASvs and overall target pressure BSvs is recorded in the power consumption data Dpc, the specified overall target A control mode with low overall power consumption is specified from among the "control modes" recorded in association with the temperature ASvs and the overall target pressure BSvs, and each temperature adjustment device 2 is controlled in the specified control mode. As a result, the total power consumption when each temperature adjustment device 2 is operated under the same control mode without specifying the power consumption again in the same control mode under the same conditions. can be specified based on the information recorded in the power consumption data Dpc, the optimum control mode (control mode with low overall power consumption) can be easily specified in a short time to control each temperature adjustment device 2 It becomes possible to

Further, in the temperature adjustment system 100 (control device 1) of this example, the control unit 13 designates any of the overall target temperature ASvs and the overall target pressure BSvs in a state where the power consumption data Dpc is stored in the storage unit 14. and the control mode (individual target temperature ASv or individual target pressure BSv) associated with the specified overall target temperature ASvs and overall target pressure BSvs is not recorded in the power consumption data Dpc, the optimum control mode is determined. A "control mode prediction process" to predict is executed.

In this "control mode prediction process", first, the control unit 13 controls the overall target temperature ASvs close to the specified overall target temperature ASvs (the overall target temperature ASvs that is slightly lower/slightly higher than the specified overall target temperature ASvs) and The control mode recorded in the power consumption data Dpc in association with the specified overall target pressure BSvs, the specified overall target temperature ASvs, and the overall target pressure BSvs close to the specified overall target pressure BSvs (the specified overall target The control mode recorded in the power consumption data Dpc in association with the overall target pressure BSvs slightly lower/slightly higher than the pressure BSvs, and the overall target temperature ASvs close to the specified overall target temperature ASvs (specified overall target associated with a global target temperature ASvs slightly lower/slightly higher than the temperature ASvs) and a global target pressure BSvs close to the specified global target pressure BSvs (a global target pressure BSvs slightly lower/slightly higher than the specified global target pressure BSvs) At least one of the three types of control modes recorded in the power consumption data Dpc is specified.

Next, based on the identified control mode, control unit 13 predicts the optimum control mode (control mode with low overall power consumption) corresponding to specified overall target temperature ASvs and specified overall target pressure BSvs. Note that when only one of the three types of control modes is recorded in the power consumption data Dpc, that one type of control mode is identified as "at least one type of control mode." An optimum control mode corresponding to the designated overall target pressure BSvs is predicted based on the controlled object. Further, when two of the three types of control modes or all three types of control modes are recorded in the power consumption data Dpc, as an example, among the specified plural types of control modes, Based on one type of control mode in which the difference between the associated overall target temperature ASvs and the specified overall target temperature ASvs or the difference between the associated overall target pressure BSvs and the specified overall target pressure BSvs is the smallest. , predicts the optimum control mode corresponding to the designated overall target pressure BSvs.

In this case, in the optimum control mode identifying process 60 described above, at least two control modes are recorded in the power consumption data Dpc in association with the overall power consumption corresponding to one designated overall target temperature ASvs (step 66 processing). Therefore, for example, when various control modes corresponding to the overall target temperature ASvs close to the specified overall target temperature ASvs are recorded in the power consumption data Dpc, the control mode with the lowest overall power consumption is selected from those control modes. A mode is specified, and based on the specified control mode, a control mode corresponding to the specified overall target temperature ASvs and with low overall power consumption (for any temperature adjustment device 2, individual target temperature It is possible to predict whether the overall power consumption can be reduced by setting ASv to a temperature higher/lower than the overall target temperature ASvs.

Specifically, as a control mode corresponding to the overall target temperature ASvs close to the specified overall target temperature ASvs, for example, only the individual target temperature ASvd for the temperature adjustment device 2d is set to the individual target temperatures ASva~ for the temperature adjustment devices 2a to 2c. When the power consumption data Dpc records that the overall power consumption can be reduced at a temperature slightly higher than ASvc, the individual target temperature for the temperature adjustment device 2d is set as the control mode corresponding to the specified overall target temperature ASvs. By setting only ASvd to a temperature slightly higher than the individual target temperatures ASva-ASvc for the temperature adjusting devices 2a-2c, it is possible to reduce the overall power consumption. Therefore, the control unit 13 makes the optimal control mode the individual target temperature ASvd for the temperature adjusting device 2d that is slightly higher than the individual target temperatures ASva to ASvc for the temperature adjusting devices 2a to 2c.

Similarly, in the optimum control mode identifying process 70 described above, at least two control modes are recorded in the power consumption data Dpc in association with the overall power consumption corresponding to one designated overall target pressure BSvs ( processing of step 76). Therefore, for example, when various control modes corresponding to the overall target pressure BSvs close to the designated overall target pressure BSvs are recorded in the power consumption data Dpc, the control mode with the lowest overall power consumption is selected from those control modes. A mode is specified, and based on the specified control mode, a control mode corresponding to the designated overall target pressure BSvs and with low overall power consumption (for any temperature adjustment device 2, an individual target pressure It is possible to predict whether the overall power consumption can be reduced by making BSv higher/lower than the overall target pressure BSvs.

Specifically, as a control mode corresponding to the overall target pressure BSvs close to the designated overall target pressure BSvs, for example, only the individual target pressure BSvd for the temperature adjustment device 2d is set to the individual target pressure BSva~ for the temperature adjustment devices 2a to 2c. When the power consumption data Dpc records that the overall power consumption can be reduced when the pressure is slightly lower than BSvc, the control mode corresponding to the specified overall target pressure BSvs is the individual target pressure for the temperature adjustment device 2d. By setting only BSvd to a pressure slightly lower than the individual target pressures BSva-BSvc for the temperature control devices 2a-2c, it is possible to reduce the overall power consumption. Therefore, the control unit 13 sets the optimum control mode to set the individual target pressure BSvd for the temperature adjusting device 2d to a pressure slightly lower than the individual target pressures BSva to BSvc for the temperature adjusting devices 2a to 2c.

Subsequently, the controller 13 controls each temperature adjustment device 2 in the predicted control mode. As a result, when operating under an operating environment close to the operating environment of the previously executed "first specific process", the power consumption amount specification, etc. in the same control mode under the same conditions will not be executed again. Even so, it is possible to operate each temperature adjustment device 2 in an operating state in which the overall power consumption is sufficiently small according to the control mode predicted based on the information recorded in the power consumption data Dpc.

Further, during the operation of the temperature control system 100, the operating environment of each temperature control device 2 (the amount of heat emitted from a heat source installed in the vicinity of the sunlight, the state of ventilation, etc.) changes. The condition of the temperature adjustment device 2 (state of consumable parts, etc.) may change. In this case, in each temperature adjustment device 2, regardless of the environmental changes as described above, the controller 28 controls the specified individual target temperature ASv to match the individual measured temperature APv, and the specified individual target pressure The refrigerating cycle 22, the air cooling mechanism 23, the blower fan 25, and the pumping pump 24 are controlled to keep the BSv and the individually measured pressure BPv in agreement, thereby continuing to adjust the temperature and pressure of the coolant Wa.

Therefore, for example, even if the temperature adjustment device 2 that has been operating without sunlight is exposed to sunlight and the temperature adjustment efficiency (cooling efficiency) of the coolant Wa by the temperature adjustment device 2 deteriorates, The individual actual measured temperature APv of the coolant Wa output from the temperature adjustment device 2 is kept in agreement with the individual target temperature ASv designated by the control device 1 . However, in the temperature adjustment device 2 with deteriorated temperature adjustment efficiency, even if the cooling liquid Wa at the same individual measured temperature APv can be output, the operation rate of the refrigeration cycle 22 and the air cooling mechanism 23 increases to compensate for the deterioration in efficiency. Individual power consumption increases only by Therefore, the overall power consumption of the temperature adjustment system 100 including such a temperature adjustment device 2 also increases.

In addition, contrary to the above example, the temperature control device 2, which had been operating in the sunlight, is no longer exposed to the sunlight, and the temperature control efficiency (cooling efficiency) of the coolant Wa by the temperature control device 2 is improved. Even so, the individual measured temperature APv of the coolant Wa output from the temperature adjustment device 2 is maintained in a state of matching the individual target temperature ASv designated by the control device 1 . However, in the temperature adjustment device 2 with improved temperature adjustment efficiency, the individual power consumption is reduced by the amount that the operation rate of the refrigeration cycle 22 and the air cooling mechanism 23 is lowered according to the improvement in efficiency. Therefore, when the temperature adjustment device 2 in a state where the individual power consumption is small is operated in a control mode with a low operation rate, the temperature adjustment system 100 is operated by increasing the operation rate of the temperature adjustment device 2 overall power consumption can be further reduced.

Therefore, in the temperature adjustment system 100 (control device 1) of the present example, when the total power consumption greatly changes beyond the predetermined amount of change (a large increase or a large decrease time), assuming that the "first start condition" is satisfied, the optimal control mode specifying process 60 and the optimal control mode specifying process 70 (first specifying process) are executed, and the newly specified optimal control Each temperature adjustment device 2 is controlled in a mode (a control mode in which the overall power consumption is low). As a result, even if the environment changes during operation, the coolant Wa can be pressure-fed to the supply target X in a state where the overall power consumption is sufficiently small in the environment after the change.

Furthermore, when the temperature adjustment system 100 is operated, the model and number of devices that make up the supply target X are changed, the feed pipe Ps and the return pipe Pr are replaced or expanded, and the temperature adjustment device 2 that makes up the temperature adjustment system 100 is changed. Replacement, number change, and type change of cooling liquid Wa to be used may be performed. Also, the temperature adjustment system 100 (the control device 1 and each temperature adjustment device 2) may be moved and used. In this case, when the usage environment is changed as described above, the operation rate of each temperature adjustment device 2 when each temperature adjustment device 2 is controlled in the control mode recorded in the power consumption data Dpc changes. , the total power consumption associated with the control mode recorded in the power consumption data Dpc does not match the actual state of the usage environment after the change. Therefore, even if a control mode in which the total power consumption is small is specified according to the information recorded in the power consumption data Dpc after the usage environment is changed, the total power consumption when each temperature adjustment device 2 is controlled in the specified control mode There is a possibility that the amount of electric power cannot be sufficiently reduced.

Therefore, in the temperature adjustment system 100 (control device 1) of this example, when the reset operation is performed on the operation unit 11, the control unit 13 stores the power consumption data Dpc assuming that the "reset condition" is satisfied. Delete from part 14. As a result, when the device is operated in a new usage environment, new power consumption data Dpc is generated in accordance with the environment after the change, and information on various control modes is gradually accumulated. By using the power consumption data Dpc, it is possible to easily identify a suitable control mode (a control mode with a low overall power consumption) that is suitable for the usage environment after the change in a short period of time.

Thus, in the control device 1, the control unit 13 causes the “adjustment unit (main In the example, at least one of the refrigerating cycle 22, the air cooling mechanism 23, and the blowing fan 25) and the pressure-feeding unit (pressure-feeding pump 24 in this example) operates in a plurality of types different from those of other temperature control devices 2. The control unit 28 is sequentially controlled in the control mode of to execute a "first specification process" for specifying the total power consumption per unit time by the temperature adjustment system 100 for each control mode, and the "first specification The control unit 28 is controlled in the control mode in which the overall power consumption amount specified by "processing" is small. Moreover, the temperature control system 100 includes the control device 1 and a plurality of temperature control devices 2 .

Therefore, according to the control device 1 and the temperature adjustment system 100, the pipe length between each temperature adjustment device 2 and the supply target X, the temperature at the installation location of each temperature adjustment device 2, and the condition of each temperature adjustment device 2 without specifying differences in various operating environments such as, or estimating the individual power consumption per unit time of each temperature adjustment device 2 based on the specified operating environment. When the "start condition of" is satisfied, the "first specific process" is executed to automatically specify the total power consumption according to the operating environment of each temperature adjustment device 2 for each of the various control modes. In addition, each temperature adjustment device 2 is controlled in a control mode in which the overall power consumption of the temperature adjustment system 100 is sufficiently low based on the specified overall power consumption, so that the specified overall target The cooling fluid Wa adjusted to the temperature ASvs is pressure-fed to the supply target X at the specified overall target pressure BSvs, and the operation is reliably and easily performed in an operating state in which the overall power consumption per unit time is sufficiently small. be able to.

In addition, in the control device 1, the control unit 13 maintains the temperature of the cooling liquid Wa pressure-fed from the temperature adjustment system 100 to the supply object X at the overall target temperature ASvs, and pressure-fed from the temperature adjustment system 100 to the supply object X. When changing the control mode in order to maintain the pressure of the coolant Wa at the overall target pressure BSvs, the predetermined "first start condition" is satisfied, and the "first specific process" is executed. do. Therefore, according to the control device 1 and the temperature adjustment system 100, when the individual power consumption of each temperature adjustment device 2 is likely to change, a switch operation or the like for instructing the start of processing is performed. Since the "first specific process" is automatically executed even if it is not performed, the coolant Wa whose temperature has been adjusted to the specified overall target temperature ASvs is supplied to the target X at the specified overall target pressure BSvs. It is possible to reliably and easily continue the operating state in which the pumping is carried out and the overall power consumption per unit time is sufficiently small.

Furthermore, according to the controller 1 and the temperature adjustment system 100, when the controller 13 is designated at least one of the new overall target temperature ASvs and the new overall target pressure BSvs, the predetermined "first By executing the "first specific process" assuming that "1 start condition" is satisfied, "new overall target temperature ASvs and new overall When the target pressure BSvs is specified, the "first specific process" is automatically executed without any switch operation to instruct the start of the process. An operating state in which the adjusted cooling liquid Wa is pressure-fed to the supply object X at the specified overall target pressure BSvs and the overall power consumption per unit time is sufficiently low can be reliably and easily continued.

In addition, in the control device 1, when the control unit 13 executes the "first specific process", the total power consumption and the corresponding control mode specified in the "first specific process", and the "first Execution of a "power consumption learning process" for generating power consumption data Dpc in which the overall target temperature ASvs and the overall target pressure BSvs specified at the start of the "specifying process" are mutually associated and stored in the storage unit 14 In addition, when any overall target temperature ASvs and overall target pressure BSvs are specified, and the control mode associated with the specified overall target temperature ASvs and overall target pressure BSvs is recorded in the power consumption data Dpc, Among the control modes recorded in the power consumption data Dpc in association with the specified overall target temperature ASvs and overall target pressure BSvs, a control mode with low overall power consumption is specified to control each controller 28 .

Therefore, according to the control device 1 and the temperature adjustment system 100, the "first specific process" can be executed again when operating under the same operating environment as when the "first specific process" was executed in the past. However, based on the information recorded in the power consumption data Dpc, each temperature adjustment device 2 can be reliably and easily operated in an operating state in which the overall power consumption is sufficiently low. As a result, it is possible to reduce the frequency of changing the control mode in order to specify the control mode in which the total power consumption is small, and as a result, it is possible to stably supply the coolant Wa to the supply target X.

In addition, in the control device 1, the control unit 13 is configured so that the overall target temperature ASvs and the overall target pressure BSvs are specified, and the control mode associated with the specified overall target temperature ASvs and the specified overall target pressure BSvs is consumed. When not recorded in the power data Dpc, the overall target temperature ASvs close to the specified overall target temperature ASvs and the control mode associated with the specified overall target pressure BSvs, the specified overall target temperature ASvs and the specified Control mode associated with overall target pressure BSvs close to overall target pressure BSvs, and control associated with overall target temperature ASvs close to specified overall target temperature ASvs and overall target pressure BSvs close to specified overall target pressure BSvs At least one of the three control modes is specified, and based on the specified at least one control mode, a control mode corresponding to the specified overall target temperature ASvs and the specified overall target pressure BSvs. A "control mode prediction process" for predicting a control mode with low overall power consumption is executed, and each control unit 28 is controlled in the predicted control mode.

Therefore, according to the control device 1 and the temperature adjustment system 100, the "first specific process" is executed when operating under an operating environment close to the operating environment of the "first specific process" executed in the past. Therefore, each temperature adjusting device 2 can be reliably and easily operated in an operation state in which the total power consumption is sufficiently small according to the control mode predicted based on the information recorded in the power consumption data Dpc. As a result, it is possible to reduce the frequency of changing the control mode in order to specify the control mode in which the total power consumption is small, and as a result, it is possible to stably supply the coolant Wa to the supply target X.

Furthermore, according to the control device 1 and the temperature adjustment system 100, the control unit 13 erases the power consumption data Dpc from the storage unit 14 when the predetermined "reset condition" is satisfied, thereby reducing the operating environment By erasing the power consumption data Dpc from the storage unit 14 when the total power consumption and the corresponding control mode recorded in the power consumption data Dpc become different from the actual state due to a large change in Also, it is possible to preferably avoid a situation in which each temperature adjustment device 2 is controlled in a control mode that makes it difficult to reduce the overall power consumption in the changed operating environment. Further, the "first specific process" is executed after the operating environment is changed, and new power consumption data Dpc is generated according to the operating environment after the change. Each temperature adjustment device 2 can be reliably and easily operated in an operating state in which the

In addition, in the control device 1, the control unit 13 causes the temperature adjustment devices 2 to operate individually and sequentially when the predetermined "second start condition" is satisfied, and the unit While executing the "second specific process" for specifying the individual power consumption per hour, when pumping the cooling liquid Wa to the supply object X, the cooling liquid Wa by the temperature adjustment device 2 with a small individual power consumption Each control unit 28 is controlled in a control mode in which the adjustment amount of the temperature of the coolant Wa by the temperature adjustment device 2 with a large individual power consumption is smaller than the adjustment amount of the temperature of . In addition, in the control device 1, the control unit 13 causes the temperature adjustment devices 2 to operate individually and sequentially when the predetermined "second start condition" is satisfied, and the unit While executing the "second specific process" for specifying the individual power consumption per hour, when pumping the cooling liquid Wa to the supply object X, the cooling liquid Wa by the temperature adjustment device 2 with a small individual power consumption Each control unit 28 is controlled in a control mode in which the adjustment amount of the pressure of the coolant Wa by the temperature adjustment device 2, which has a large individual power consumption, is smaller than the adjustment amount of the pressure of .

Therefore, according to the control device 1 and the temperature adjustment system 100, it is possible to reliably and easily specify in what operating state each temperature adjustment device 2 should be operated in order to reduce the overall power consumption. In addition, since it is possible to reliably and easily identify which temperature adjustment device 2 is to have its operating state different from that of the other temperature adjustment devices 2 in the "first identification process", the total power consumption is sufficiently reduced. Each temperature control device 2 can be reliably and easily operated in a relatively small number of operating states.

Furthermore, according to the control device 1 and the temperature adjustment system 100, the control unit 13 sets the predetermined "first start condition ” is satisfied, and when the individual power consumption of at least one temperature adjustment device 2 changes and “the overall power consumption greatly changes”, the process Since the "first specific process" is automatically executed without performing a switch operation or the like to instruct the start of the cooling liquid Wa whose temperature has been adjusted to the specified overall target temperature ASvs, the specified overall target temperature It is possible to reliably and easily continue the operating state in which the supply target X is pumped at the pressure BSvs and the overall power consumption per unit time is sufficiently small.

The configurations of the “control device” and the “temperature adjustment system” are not limited to the configuration examples of the control device 1 and the temperature adjustment system 100 described above. For example, in a state in which all the temperature adjusting devices 2 (in the above example, four temperature adjusting devices 2a to 2d) constituting the temperature adjusting system 100 are operated, the individual target temperature ASv of any one of the temperature adjusting devices 2, An example of operating each temperature adjustment device 2 in a control mode that makes the individual target pressure BSv different from that of the other temperature adjustment devices 2 has been described, but one of the temperature adjustment devices 2 is stopped in the "various control modes". and a control mode for resuming the operation of the temperature adjustment device 2 in a stopped state.

Also, when the temperature adjustment system 100 is newly installed or the installation location is changed, the supply capacity specifying process 50 is executed assuming that the "second start condition" is satisfied when the start is instructed by the switch operation of the operation unit 11. Although an example has been described, the timing of executing the supply capacity specifying process 50 and the "second start condition" for executing the supply capacity specifying process 50 are not limited to this example. Specifically, as an example, when the power supply to the temperature adjustment system 100 (control device 1) is turned on, the supply capacity specifying process 50 is executed assuming that the "second start condition" is satisfied. The supply capacity specifying process 50 can be executed assuming that the "second start condition" is satisfied when the date and time arrive or when the operating time reaches a preset time.

Similarly, the timing for executing the optimum control mode identification process 60 and the optimum control mode identification process 70 and the "first start condition" for executing these are not limited to the above examples, and as an example, the temperature adjustment system 100 (control device 1) is powered on, the optimum control mode specifying process 60 and the optimum control mode specifying process 70 are executed assuming that the "first start condition" is satisfied, or a preset date and time arrives. or when the operating time reaches a preset time, the optimum control mode specifying process 60 and the optimum control mode specifying process 70 can be executed assuming that the "first start condition" is satisfied. can.

In addition, although the configuration including the temperature adjustment device 2 having two systems of the refrigeration cycle 22 and the air cooling mechanism 23 as the "adjustment unit" has been described as an example, only one of the refrigeration cycle 22 and the air cooling mechanism 23 is used as the "adjustment unit". It is also possible to configure a "temperature adjustment device" by providing it as an adjustment unit. Furthermore, in place of (or in addition to) either or both of the refrigeration cycle 22 and the air cooling mechanism 23 of the temperature adjustment device 2, a heat pump may be provided to constitute an "adjustment section." . Further, the temperature adjustment of the "heat transfer liquid" is not limited to cooling, and the "adjustment section" may be configured with a heater, a boiler, or the like that adjusts the temperature by heating. In this case, since the temperature of the "heat transfer liquid" is increased by pressurizing it, it is also possible to employ a configuration in which the "pumping section" is used as one element of the "adjustment section (heating section)."

Furthermore, the configuration in which the circulation pump 43 that adjusts the pressure of the cooling liquid Wa by changing the rotation speed has been described as an example, but instead of such a configuration (or such a configuration In addition to ), a variable flow rate control valve is placed at the liquid outlet of the "temperature adjustment device", and a "pumping part" that adjusts the pressure of the "heat transfer liquid" by changing the opening of the control valve is adopted. can also The control device 1 is configured to specify the overall measured pressure BPvs based on the sensor signal S4 from the pressure sensor 4, and the temperature control device is configured to specify the individual measured pressure BPv based on the sensor signal S27 from the pressure sensor 27. 2 was described as an example, but for specifying the "pressure of the heat transfer fluid," a flow sensor is used instead of the pressure sensor, and the flow rate specified based on the sensor signal from the flow sensor is replaced with the pressure. can also be used to control each part.

Further, the configuration of the temperature adjustment system 100 including four temperature adjustment devices 2a to 2d has been described as an example, but the number of “temperature adjustment devices” that constitute the “temperature adjustment system” is two, three, and so on. It can be a single unit, or a multiple of five or more units.
