Description

Temperature Control System {CONTROL SYSTEM FOR TEMPERATURE}

The present invention relates to a temperature control system, and more particularly, to a temperature control system capable of controlling at least one air conditioning unit provided in a separate space in a central control unit.

In general, various air-conditioning and heating equipment is provided in buildings and industrial sites. In particular, there are individual rooms in the building that can be used by one or two small people and many people, and each individual space can be equipped with heating and heating facilities.

These individual spaces control the temperature by turning on or off air conditioning equipment. At this time, the heating and cooling equipment is controlled by the central system of the building to control the temperature of the individual space, otherwise the user directly controls the temperature to adjust.

Here, if a plurality of air-conditioning devices are provided in individual spaces, since the air-conditioning devices are all operated, the temperature of the individual space is too low or high, so that the indoor / outdoor temperature difference is greatly increased. As a result, the physical rhythm of the user using the individual space is broken or unnecessary energy is consumed.

In addition, when the air conditioning equipment is controlled by the central heating system, the individual temperature is controlled at a constant temperature irrespective of the temperature of each individual space.

In order to solve the above problems, a patent for controlling the heating and cooling device in the central system has been applied, but there is a lack in controlling the heating and cooling device according to the environment of the individual space.

Temperature control system according to an embodiment of the present invention, it is possible to prevent unnecessary energy waste while operating the heating and cooling equipment.

The temperature control system according to an embodiment of the present invention can easily control the temperature of the individual space by setting the upper limit section temperature and the lower limit section temperature according to the temperature of the individual space.

Temperature control system according to an embodiment of the present invention, by measuring the temperature of the individual space in real time, it is possible to efficiently manage the individual space by collecting the temperature of the individual space.

A temperature control system according to an embodiment of the present invention, provided with at least one individual space of a building provided with a plurality of air conditioning equipment, the sensor unit for measuring the temperature of the individual space in real time; A central controller configured to set an upper limit section temperature and a lower limit section temperature in order to control the operation of the plurality of cooling and heating devices, and control the operation of the plurality of heating and cooling devices by comparing the measured individual space temperature with the upper limit section temperature and the lower limit section temperature; And an individual controller provided in each of the plurality of air-conditioning and heating devices, for receiving and storing the upper and lower section temperatures from the central controller and transmitting the temperature of the individual space measured by the sensor unit to the central controller. It includes.

By the above configuration, it is possible to prevent unnecessary energy use while operating the heating and cooling equipment, and to efficiently manage the temperature of the individual space.

The plurality of air conditioning units are operated as air conditioners, and the central control unit operates all of the plurality of air conditioning units when the temperature of the measured individual space enters the upper limit section temperature, and the temperature of the measured individual space is the upper limit section. When the temperature falls between the lower limit section temperature, the plurality of air conditioning units may be sequentially operated or stopped, and when the measured individual space temperature enters the lower limit section temperature, the plurality of air conditioning units may be controlled to stop.

That is, when the temperature of the individual space rises above the upper and lower section temperature set by the central control unit, the heating and cooling device may be operated to lower the temperature of the individual space. In this case, if the heating and cooling equipment continues to operate, the temperature of the individual space is continuously lowered, so that the set upper limit and lower limit section temperatures may be regained. In order to prevent such a situation, when the temperature of the individual space is out of the upper and lower limit temperature, the operation of the air conditioning equipment is sequentially stopped to maintain the temperature of the individual space within the upper and lower limit temperature.

On the other hand, the plurality of air-conditioning equipment is operated as a heater, the central control unit stops all the plurality of air-conditioning equipment when the temperature of the measured individual space enters the upper limit section temperature, the temperature of the measured individual space is the upper limit When the section temperature and the lower limit section temperature is entered, the plurality of air conditioners are sequentially operated or stopped, and when the measured individual space temperature enters the lower limit section temperature, the plurality of air conditioning units can be controlled to operate.

As described above, when the heater is continuously provided in the individual space, the user may feel uncomfortable because the temperature of the individual space increases over time. In order to prevent such a phenomenon, the central control unit controls all operations of the heating and cooling equipment to maintain the temperature of the individual space.

Meanwhile, a plurality of sensor units may be provided, and the individual space may be provided with a collector configured to collect the temperature of the individual space measured by the sensor unit before transmitting the temperature of the individual space from the individual controller to the central controller. The collecting unit may add the temperatures of the individual spaces received to each individual control unit of the plurality of air-conditioning devices provided in the individual spaces and transmit the sums to the central control unit.

In this case, the collector may transmit the measured temperature of the individual space received from the individual controller to the central controller. In this way, even if a plurality of individual control units are provided by the collection unit, the temperature of the individual spaces is transmitted to the central control unit, so it is easy to check whether the individual spaces deviate from the upper and lower limit section temperatures.

On the other hand, the temperature control system according to another embodiment of the present invention is provided with at least one individual space of the building provided with a heating and cooling device, the sensor unit for measuring the temperature of the individual space of the individual space in real time; And a central controller configured to set an upper limit section temperature and a lower limit section temperature for controlling the operation of the air conditioning unit, and transmit upper and lower section temperatures to the air conditioning unit. And an individual control unit provided to the air-conditioning unit, which receives and stores the upper and lower limit section temperatures transmitted from the central control unit, and transmits the temperature of the individual spaces measured by the sensor unit to the central control unit. Outside the upper and lower section temperature, the heating and cooling equipment can be operated to the maximum and minimum to prevent the temperature of the individual space from escaping from the upper and lower section temperatures.

According to the above configuration, even if one air conditioner is provided in the individual space, the air conditioner can be efficiently operated so as not to deviate from the temperature of the individual space, and as a result, unnecessary waste of energy can be saved.

In this case, the individual controller may transmit the temperature of the individual space measured by the sensor unit to the central controller in real time, and the individual controller may include a transmitter for transmitting the temperature of the individual space to the central controller. In addition, the central control unit may include a storage unit for storing the temperature of the individual space transmitted from the transmitter in real time.

As such, the storage unit stores the temperature of the individual space transmitted from the transmitter in real time, so that the temperature of the stored individual space may become a reference value when the upper limit section temperature and the lower limit section temperature are reset.

For example, since the temperature of the individual space may be different for each season, the upper and lower limit section temperatures may be reset for each season. At this time, the set upper limit and lower limit section temperature may be reset based on the temperature of the most recent individual space among the temperatures stored in the storage unit. Since the upper and lower section temperature is set based on the most recent temperature, the temperature of the individual space can be adjusted according to the surrounding environment, and as a result, the user can use the individual space in a comfortable environment.

On the other hand, a plurality of sensor unit may be provided, wherein the individual control unit may transmit the average temperature or the maximum temperature of the current temperature in the plurality of sensor unit to the central control unit. In the sensor unit transmitted to the central control unit, the average temperature or the maximum temperature of the current temperature may be a reference value for setting the upper limit and lower limit section temperature. As described above, the upper limit section temperature and the lower limit section temperature are set based on the reference value. Therefore, the user uses the individual space in a more comfortable environment.

According to an embodiment of the present invention, comparing the upper limit section temperature and the lower limit section temperature set in the central controller with the current temperature in the individual space to control the operation of the heating and cooling device when the temperature of the current in the individual space deviates from the upper and lower limit temperature Therefore, the temperature of the individual space can be kept constant, it is possible to prevent unnecessary operation of the heating and cooling equipment to prevent waste of energy.

According to one embodiment of the invention, by transmitting the temperature of the individual space measured in real time to the central control unit and stored in real time, when setting the upper and lower limit section temperature in the central control unit to set based on the stored upper and lower limit section temperature Can be. As a result, since the central control unit controls the air conditioning unit according to the temperature changing according to the surrounding environment, season, etc. of the individual space, it is possible to minimize the use of unnecessary air conditioning unit, and also to reduce the inconvenience of the user.

According to one embodiment of the invention, the central control unit can monitor in real time the operation and shutdown of the heating and cooling equipment provided in the individual space. In this way, by checking the operation and shutdown of the air conditioning equipment in real time, if the air conditioning equipment cannot be controlled due to a defect in the central control unit, the air conditioning equipment is controlled individually so that the air conditioning equipment is not used excessively or is not used when necessary. It is possible to optimize the environment of users who use individual spaces.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited or limited by the embodiments. Like reference numerals in the drawings denote like elements.

1 is a view schematically showing a temperature control system according to an embodiment of the present invention, Figure 2 is a block diagram according to the configuration of the temperature control system of Figure 1, Figure 3 is an embodiment of the present invention It is a graph showing the operation of the heating and cooling equipment according to the temperature change.

Prior to describing the drawings, the individual space 140 may be an office, a room in a house, and the like, and for convenience of description, in one embodiment of the present invention, an office and The same individual space will be described by way of example.

Temperature control system 100 according to an embodiment of the present invention may be provided with a plurality of air conditioning equipment 160 in the individual space 140, the central control unit 120 for controlling the temperature of the plurality of air conditioning equipment 160 And provided in the individual space 140, and includes a sensor unit 150 for measuring the temperature of the individual space 140.

The central control unit 120 may be referred to as a central system for controlling the air conditioners 160 provided in each individual space 140 in a building, a site, and the like. 160 can be controlled remotely.

The central control unit 120 may monitor in real time the state of the individual space 140 that is remotely controlled through the main controller 122 and the main controller 122 that can control the plurality of air conditioning and heating device (160). It may include a central PC (124).

The main controller 122 may be provided with various operation buttons (not shown) and a display (not shown) for checking a user's operation state to adjust the temperature of the individual space 140.

On the other hand, the central control unit 120 may control the air conditioning unit 160 using various communication models. For example, the central control unit 120 controls the plurality of air-conditioning devices 160 by changing the communication model of the air-conditioning device 160 according to the model of each air-conditioning device such as TIP / IP, 485 communication, Zigbee communication. Can be.

In addition, the central controller 170 may set the upper limit section temperature and the lower limit section temperature of the individual space 140. The upper limit section temperature and the lower limit section temperature may be reference values at which the air conditioning and heating device 160 may operate, and the upper and lower limit sections may be changed according to the surrounding environment and the occupants.

For example, the central controller 120 may set the upper limit section temperature to 26 ° C ~ 28 ° C, the lower limit section temperature to 18 ° C ~ 20 ° C. On the basis of the upper limit and the lower limit section temperature set as described above, the heating and cooling device 160 may be operated within a temperature that does not deviate from the set temperature. As such, when the central control unit 120 sets the upper limit section temperature and the lower limit section temperature, the temperature of the individual space 140 may be kept constant so that the user's use environment may be optimized. In addition, by minimizing the difference between the temperature of the individual space 140 and the outdoor temperature it is possible to minimize the energy consumed by the plurality of air conditioning equipment (160).

At this time, the central control unit 120 may set the upper and lower limit section temperature according to the season, group, schedule. For example, it can be set by changing the upper limit section temperature and the lower limit section temperature in response to the selection of air conditioning equipment according to the summer and winter. For example, since the upper limit section temperature in summer may be lower than the upper limit section temperature in winter, it is possible to optimize the environment of the individual space 140 by setting the upper limit section temperature and the lower limit section temperature differently according to each season. In addition, the upper limit section temperature and the lower limit section temperature may be changed according to the user's group. In the case of industrial zones, the amount of activity may be higher than that of clerical workers, so the upper limit section temperature can be set lower to prevent the heating and cooling equipment from rising to higher temperatures.

The individual space 140 may be provided with a sensor unit 150 that can measure the temperature of the individual space 140. The sensor unit 150 according to an embodiment of the present invention is described with an example provided in the individual space 140, but in some cases, the sensor unit may be provided in the air conditioning unit 160.

The sensor unit 150 may measure the temperature of the individual space 140 in real time (S410). The measured temperature of the individual space 140 may be transmitted to the central controller 170, and the temperature of the transmitted individual space may be a reference value of the upper limit and lower limit section temperatures set by the central controller 170.

In this case, at least one sensor unit 150 may be provided in the individual space 140. For example, when one sensor unit 150 is provided in the individual space 140, the temperature B of the individual space measured by the sensor unit 150 may be transmitted to the individual control unit 170 in real time. Unlike this, when a plurality of sensor units 150 are provided in the individual space 140, the individual controller 170 measures the temperature of the individual space 140 measured by the sensor unit 150 at either the average temperature or the maximum temperature. The control unit 120 may transmit. Here, the average temperature or the maximum temperature transmitted by the individual controller 170 may be changed according to the user's setting.

On the other hand, at least one air-conditioning device 160 may be provided in the individual space 140, and in the following, an example of providing a plurality of air-conditioning devices 160 will be described. In addition, the air-conditioning device 160 according to an embodiment of the present invention may be a temperature control device such as a heater, air conditioner, etc. In the present invention, for the convenience of description, the air conditioner (for example) will be described below. The present invention is not limited by the type of 160).

The air conditioning and heating device 160 may include an individual controller 170 that receives the temperature of the individual space 140 measured by the sensor unit 150, and the individual controller 170 centralizes the temperature of the received individual space. The control unit 170 may transmit.

At this time, since each air conditioner 160 may be provided with a separate control unit 170, it is preferable to transmit the temperature of the individual space received from each individual control unit 170 as a signal to the central control unit 170. . Therefore, the individual space 140 may be provided with a collection unit 190 that can collect the temperature of the individual space transmitted to each individual control unit 170.

The collection unit 190 may add the temperatures of the individual spaces transmitted by the individual controller 170 to the central controller 170, and the central controller 170 may receive the temperature of the individual spaces in a predetermined range. have. For example, two air-conditioning devices may be provided in the individual space 140. At this time, if the temperature of the individual space received from each individual controller is 26 ° C, 29 ° C, respectively, the collection unit 190 to transmit a temperature in the range of 26 ° C ~ 29 ° C to the central control unit 170 Can be. As such, when the central controller 170 receives a predetermined range of temperature, the range of the upper limit section temperature and the lower limit section temperature can be efficiently adjusted.

On the other hand, the central control unit 170 may include a storage unit 130 that can store the temperature of the individual space transmitted from the collection unit 190. The storage unit 130 may be a reference value when the upper limit section temperature and the lower limit section temperature are reset by the central controller 170 by storing the temperature of the individual space of the individual space 140.

For example, the individual space 140 may change in temperature according to season, weather, or the like. In particular, the temperature difference of the individual space measured by the sensor unit 150 may change because the interval between the upper limit and the lower limit of the individual space 140 is much different depending on the season. Since the upper and lower section temperature can be adjusted according to the changing temperature, the user can use the individual space 140 in a more comfortable environment.

When the temperature of the individual space 140 deviates from the upper and lower limit temperature, the central control unit 170 simultaneously controls the plurality of air conditioning and heating devices 160 so that the temperature of the individual space 140 does not deviate from the upper and lower limit temperature ranges. Can be operated. At this time, if the temperature of the individual space 140 is again out of the upper and lower limit temperature, the operation of the air conditioning equipment 160 is sequentially stopped to maintain the temperature of the individual space 140 within the upper and lower limit temperature. have.

That is, referring to FIG. 3, when the temperature of the individual space 140 is increased to exceed the upper limit section temperature, all the heating and cooling devices 160 may be operated to control this. When all of the heating and cooling device 160 is operated, the temperature of the individual space 140 can be rapidly lowered. When the temperature is lowered and the temperature (B) of the individual space is out of the lower limit section temperature (C), the air-conditioning device ( The operation of the 160 is stopped to control the temperature of the individual space 140. Here, the air-conditioning and heating device 160 may stop the operation sequentially so as not to increase the temperature of the individual space 140 temporarily, but to sequentially adjust the temperature. As such, since the cooling and heating device 160 is sequentially stopped, the temperature of the individual space 140 is not temporarily changed, and energy saving can be optimized by controlling the operation of the cooling and heating device 160 unnecessarily.

For example, when the plurality of air conditioners 160 are operated as air conditioners, the central controller 120 operates all of the plurality of air conditioners 160 when the temperature B of the individual space enters the upper limit section temperature A. When the temperature (B) of the individual space enters the lower limit section temperature (C), all of the plurality of heating and cooling devices 160 may be stopped. At this time, when the temperature (B) of the individual space enters the upper and lower limit temperature (A, C), it is possible to control the temperature (B) of the individual space by stopping or operating the plurality of air conditioning equipment 160 sequentially. .

In addition, when the plurality of air conditioning equipment 160 is operated as a heater, the central control unit 120 may stop all of the plurality of air conditioning equipment 160 when the temperature (B) of the individual space enters the upper limit section temperature (A). Alternatively, when the temperature of the individual space 140 enters the lower limit section temperature (C), all of the plurality of heating and cooling devices 160 may be operated. At this time, when the temperature (B) of the individual space enters between the upper and lower limit temperature (A, C), the plurality of air-conditioning devices 160 can be stopped or operated sequentially to maintain the temperature (B) of the individual space. do.

On the other hand, Figure 4 is a diagram showing a temperature control system according to another embodiment of the present invention.

Prior to describing other embodiments according to the present invention, the same or equivalent components as those described above will be denoted by the same or equivalent components, and detailed description thereof will be omitted.

Referring to FIG. 4, the central control unit 170a of the temperature control system 100a according to another embodiment of the present invention sets the upper and lower limit section temperatures C of the individual space 140a to the air conditioner 160a. I can send it. In this case, the sensor unit 150a may measure the temperature B of the individual space of the individual space 140a in real time, and measure the temperature of the individual space measured by the individual control unit 170a provided to the air conditioner / heater 160a. B) and the upper and lower interval temperatures C transmitted from the central controller 170a may be compared.

For example, when the temperature of the individual space 140a is to be lowered, the temperature of the individual space 140a may be lowered by maximally operating the air conditioning and heating device 160a. When the temperature of the individual space (140a) is lowered out of the lower limit section temperature (C), it is possible to re-adjust the temperature of the individual space (140a) by minimizing the operation of the air conditioning equipment (160a).

Thus, even if one air-conditioning device 160a is provided in the individual space 140a, the temperature of the individual space 140a can be maintained at the temperature B of the individual space by maximizing or minimizing the operation of the air-conditioning device 160a. Will be. As a result, the environment of the user using the individual space 140a may be optimized, and energy saving may be maximized by reducing unnecessary use of the air conditioning and heating device 160a. On the other hand, the temperature control system (100, 100a) according to an embodiment of the present invention and the description will be described by taking an example of lowering the temperature of the individual space (140, 140a), the individual space ( It is applicable also when raising the temperature of 140 and 140a).

By the above configuration, the central control unit, which is a central remote system, can individually control the air conditioning equipment of the individual space to finely adjust the temperature of the individual space, thereby optimizing the environment of the individual space.

In addition, it controls air-conditioning equipment according to the surrounding environment, and can stop and operate the air-conditioning equipment according to the upper and lower section temperature set in the central control unit, thereby preventing unnecessary heating and cooling equipment to prevent waste of energy. Can be.

Although the preferred embodiments of the present invention have been described above by way of example, the scope of the present invention is not limited to these specific embodiments, and may be appropriately changed within the scope described in the claims.
