(Embodiment 1)
The air conditioner control device according to Embodiment 1 estimates the room temperature when the air conditioner performs air conditioning, and sends the estimation result to the air conditioner in order to bring the room temperature closer to the set temperature set by the user. It is a feedback device. This control device uses a thermal energy model of the room in which the indoor unit is installed and a fluid model of the air in the room in order to accurately estimate the indoor temperature in a short period of time.

First, an air conditioner to be controlled will be described with reference to FIGS. 1 to 4. FIG. Next, the configuration of the control device will be described with reference to FIGS. 5 to 12. FIG. Next, the operation of the control device will be described with reference to FIGS. 13 and 14. FIG. Hereinafter, the control device for the air conditioner is simply referred to as the control device.

FIG. 1 is a block diagram of an air conditioner 100, which is an object controlled by a control device 1A according to Embodiment 1. As shown in FIG. FIG. 2 is a cross-sectional view of the indoor unit 130 included in the air conditioner 100. As shown in FIG. FIG. 3 is a conceptual diagram of an example of the direction of the wind blown by the indoor unit 130. As shown in FIG. FIG. 4 is a conceptual diagram of another example of the direction of the wind blown by the indoor unit 130. As shown in FIG. In addition, in FIGS. 3 and 4, for easy understanding, the direction of the wind blown by the indoor unit 130 is indicated by enclosing the area where the wind blows at a specific wind speed with a dotted line.

As shown in FIG. 1, the air conditioner 100 includes a compressor 121, a four-way valve 122, an outdoor heat exchanger 123, an expansion valve 124, and an indoor heat exchanger 131, which are connected by refrigerant pipes 110 and through which refrigerant flows. ing.

Compressor 121 , four-way valve 122 , outdoor heat exchanger 123 and expansion valve 124 are parts of outdoor unit 120 . The compressor 121 has a motor 125 and compresses the refrigerant as the motor 125 rotates. The four-way valve 122 switches the flow of refrigerant in the refrigerant pipe 110 . The outdoor heat exchanger 123 is installed outdoors and blows outdoor air with a fan 126 . As a result, the refrigerant flowing through the outdoor heat exchanger 123 exchanges heat with the outdoor air. Expansion valve 124 expands the refrigerant.

On the other hand, the indoor heat exchanger 131 is a component of the indoor unit 130 . The indoor heat exchanger 131 is installed indoors and blows indoor air with a fan 132 . Thereby, the refrigerant flowing through the indoor heat exchanger 131 exchanges heat with the indoor air.

These members of the outdoor unit 120 and the indoor unit 130 are arranged in the order of the compressor 121, the four-way valve 122, the outdoor heat exchanger 123, the expansion valve 124, the indoor heat exchanger 131, the four-way valve 122, and the compressor 121. 110 are connected. This forms a refrigerant circuit for circulating the refrigerant. The refrigerant circuit cools or heats indoor air by switching the flow of the refrigerant with the four-way valve 122 .

Specifically, when the four-way valve 122 is switched to one direction, the refrigerant flows to the outdoor heat exchanger 123 after being turned into a high-temperature, high-pressure gas by the compressor 121 . Further, the refrigerant exchanges heat with the outdoor air in the outdoor heat exchanger 123 and is cooled, and then expanded in the expansion valve 124 to change into a low-temperature liquid. The low-temperature and liquid refrigerant flows to the indoor heat exchanger 131 and exchanges heat with the indoor air in the indoor heat exchanger 131 . At this time, the refrigerant absorbs the heat of the indoor air. As a result, the room is cooled. After cooling the room, the refrigerant returns to the compressor 121 .

When the four-way valve 122 is switched from this state, the refrigerant flows in the opposite direction. That is, the refrigerant flows from compressor 121 to indoor heat exchanger 131 . The refrigerant is cooled by exchanging heat with indoor air in the indoor heat exchanger 131, and further expanded in the expansion valve 124 to change into a low-temperature liquid. Subsequently, the refrigerant flows to the outdoor heat exchanger 123 , exchanges heat with outdoor air, and returns to the compressor 121 . In this case, the refrigerant releases heat to the indoor air when heat-exchanging with the indoor air in the indoor heat exchanger 131 . As a result, the room is heated.

Thus, the air conditioner 100 operates in cooling or heating mode by switching the four-way valve 122 . In order to realize this operation according to the user's intention, the air conditioner 100 includes a remote controller 140, and an indoor unit control section 150 and an outdoor unit control section 160 that operate based on the output of the remote controller 140. there is

The remote controller 140 has a selection button 141 for the user to select the cooling or heating operation mode of the air conditioner 100, a temperature setting button 142 for the user to set the target temperature of the air conditioning, and a target air volume for the user to set. and a wind direction setting button 144 for the user to set the target wind direction. The remote controller 140 also includes a control section 145 having an MPU (Micro Processing Unit). When any one of the selection button 141, the temperature setting button 142, the air volume setting button 143, and the air direction setting button 144 is pressed, the control unit 145 transmits setting data set by the operation to the indoor unit control unit 150. .

The setting data is the data set by the user by pressing the button, among the data of the operation mode, temperature, air volume and wind direction. Hereinafter, the operation mode, temperature, air volume, and air direction set by the user pressing the selection button 141, temperature setting button 142, air volume setting button 143, and air direction setting button 144 are referred to as setting mode, set temperature, set air volume, and , is called the set wind direction.

The indoor unit control unit 150 controls the number of rotations of the fan 132 based on the setting data every time it receives setting data for any one of the setting mode, the setting temperature, the setting air volume, and the setting air direction. Thereby, the indoor unit controller 150 adjusts the air volume of the fan 132 . As a result, the amount of heat transferred from the refrigerant flowing in the indoor heat exchanger 131 to the indoor air is adjusted, and the cooling or heating temperature is adjusted.

In addition, the indoor unit control unit 150 adjusts the direction of the air blown by the fan 132 based on the setting data every time it receives any setting data of the setting mode, the setting temperature, the setting air volume, and the setting air direction. do.

Specifically, as shown in FIG. 2, the indoor unit 130 includes a wind direction control plate 133 that can change the vertical direction of the wind W generated by the fan 132 by tilting the plate surface in the vertical direction. The indoor unit 130 also includes a wind direction control plate 134 that can change the direction of the wind W generated by the fan 132 in the left-right direction by tilting the plate surface in the left-right direction. The indoor unit control section 150 adjusts the inclination of the plate surface of the wind direction control plate 133 or 134 based on the setting data each time the setting data is received. Thereby, the indoor unit controller 150 adjusts the wind direction of the fan 132 as shown in FIGS. 3 and 4 .

Further, the indoor unit control unit 150 transmits the setting data to the outdoor unit control unit 160 every time it receives any setting data of the setting mode, the setting temperature, the setting air volume, and the setting air direction.

The outdoor unit control unit 160 switches the four-way valve 122 according to the received setting data. Thereby, the air conditioner 100 operates in the mode set by the user, that is, in the cooling or heating mode.

Also, the outdoor unit control unit 160 controls the rotation frequency of the motor 125 based on the received setting data. Thereby, the outdoor unit control unit 160 adjusts the degree of compression of the refrigerant by the compressor 121 . As a result, the temperature of the coolant is adjusted.

The outdoor unit control unit 160 controls the opening degree of the expansion valve 124 based on the received setting data. Thereby, the outdoor unit control unit 160 adjusts the degree of pressure reduction of the refrigerant. As a result, the temperature of the coolant is adjusted.

The outdoor unit control unit 160 controls the rotation speed of the fan 126 based on the received setting data. Thereby, the outdoor unit control section 160 adjusts the amount of heat transferred from the outdoor air to the refrigerant in the outdoor heat exchanger 123 . As a result, the cooling or heating temperature is adjusted.

In addition, the air conditioner 100 includes an indoor temperature sensor 170 that measures the indoor temperature and transmits the measurement result to the indoor unit controller 150 . The indoor unit control unit 150 controls the rotational speed of the fan 132 and the inclination of the plate surface of the airflow direction control plate 133 or 134 based on not only the setting data but also the indoor temperature data measured by the indoor temperature sensor 170 . The indoor temperature sensor 170 is an example of the indoor thermometer referred to in this specification.

In addition, the indoor unit controller 150 transmits indoor temperature data from the indoor temperature sensor 170 to the outdoor unit controller 160 . The outdoor unit control unit 160 controls the rotation frequency of the motor 125 of the compressor 121, the opening degree of the expansion valve 124, and the rotation speed of the fan 126 based on the indoor temperature data as well as the setting data.

As described above, in the air conditioner 100, the outdoor unit 120 and the indoor unit 130 operate based on the set mode, set temperature, set air volume, set wind direction, and indoor temperature data set in the remote controller 140. . Accordingly, the outdoor unit 120 and the indoor unit 130 operate in the setting mode set by the user. In addition, the outdoor unit 120 and the indoor unit 130 harmonize the air in the room based on the set temperature, set air volume, and set wind direction set by the user.

However, the size of the room to be air-conditioned is often different for each room in which the air conditioner 100 is installed. As a result, when the room is air-conditioned by the air conditioner 100, the room temperature may not reach the set temperature by the target time desired by the user. Also, the room temperature at the position where the user is in the room may not reach the set temperature. Against this background, it is desirable to simulate in advance what the temperature of an arbitrary position in the room will be at a target time, and to control the operation of the air conditioner 100 based on the result.

Therefore, in the air conditioner 100, when the air conditioner 100 operates at the user's set temperature, set air volume, and set wind direction, the temperature distribution in the room after that is estimated, and based on the estimation result, the air conditioner A controller 1A is provided for coordinating the operation of 100. FIG. Next, the configuration of the control device 1A will be described with reference to FIGS. 5 to 12. FIG.

FIG. 5 is a block diagram of control device 1A for air conditioner 100 according to Embodiment 1. As shown in FIG. 6 to 10 are schematic diagrams of a data table 51, heat conduction data 52, room data 53, indoor airflow distribution data 54, and judgment data 55 stored in the storage unit 50 of the control device 1A. FIG. 11 is a schematic diagram of a cell 210 in a room 200 used for calculation by the temperature distribution estimator 30 provided in the control device 1A. FIG. 12 is a hardware configuration diagram of the control device 1A. In order to facilitate understanding, FIG. 5 also shows the main configuration of the air conditioner 100 in addition to the configuration of the control device 1A.

As shown in FIG. 5 , the control device 1A includes a parameter identifying unit 10 that identifies the wind characteristic parameter that the indoor unit 130 blows into the room, and when the indoor is air-conditioned with the wind of the wind characteristic parameter identified by the parameter identifying unit 10: A representative temperature estimating unit 20 that estimates the representative temperature in the room after a certain period of time, and a temperature for estimating the subsequent indoor temperature distribution when air conditioning is performed from the temperature at the representative point in the room estimated by the representative temperature estimating unit 20. A distribution estimating unit 30, an air conditioning condition adjusting unit 40 that adjusts the air conditioning conditions of the outdoor unit 120 and the indoor unit 130 according to the temperature distribution estimated by the temperature distribution estimating unit 30, and various data are stored. and a wireless communication module 60 for communicating with the indoor unit controller 150 .

The parameter specifying unit 10 is a part that specifies parameters necessary for calculation from the air conditioning conditions of the outdoor unit 120 and the indoor unit 130 . As will be described later, the representative temperature estimating unit 20 and the temperature distribution estimating unit 30 use a thermal energy model of the room 200 instead of an operation model for estimating the indoor temperature from the air conditioning conditions of the outdoor unit 120 and the indoor unit 130. and a fluid model to estimate the room temperature. Therefore, the computation requires thermal energy and fluid parameters instead of the air conditioning conditions of the outdoor unit 120 and the indoor unit 130 . The parameter identification unit 10 identifies this parameter from the air conditioning conditions of the outdoor unit 120 and the indoor unit 130 .

Specifically, the control device 1A and the indoor unit control section 150 have wireless communication modules 60 and 151, respectively. The parameter identification unit 10 is connected to the indoor unit control unit 150 via the network 70 by wireless communication modules 60 and 151 . The parameter identification unit 10 acquires data on the air conditioning conditions of the outdoor unit 120 and the indoor unit 130 from the indoor unit control unit 150 .

Here, the air conditioning conditions of the outdoor unit 120 and the indoor unit 130 are the switching direction of the four-way valve 122 provided in the outdoor unit 120, the rotation frequency of the compressor 121, the opening degree of the expansion valve 124, and the rotation of the fan 126. number, the number of revolutions of the fan 132 provided in the indoor unit 130, and the inclination of the wind direction control plates 133 and 134.

The air conditioner 100 includes an outdoor temperature sensor 180 that measures the outdoor temperature and transmits the outdoor temperature to the indoor unit controller 150 in addition to the indoor temperature sensor 170 described above. The parameter identification unit 10 acquires the indoor temperature measured by the indoor temperature sensor 170 and the outdoor temperature measured by the outdoor temperature sensor 180 via the wireless communication modules 60 and 151 . The outdoor temperature sensor 180 is an example of the outdoor thermometer referred to in this specification.

The storage unit 50 stores a data table 51 obtained in advance through experiments. In the data table 51, as shown in FIG. 6, the data of the air conditioning conditions, the indoor temperature and the outdoor temperature, and the wind of the wind blown into the room by the indoor unit 130 under the air conditioning conditions, the indoor temperature and the outdoor temperature. are associated with characteristic parameters.

Here, the wind characteristic parameter is each parameter of air volume, wind direction, and wind temperature for specifying the wind blown into the room by the indoor unit 130 .

The parameter specifying unit 10 reads the data table 51 from the storage unit 50 shown in FIG. The parameter specifying unit 10 transmits the specified wind characteristic parameters to the representative temperature estimating unit 20 and the temperature distribution estimating unit 30 .

The representative temperature estimating unit 20 is a part that estimates the representative temperature in the room at the initial stage when the air conditioner 100 conditions the air. Since the temperature distribution estimating unit 30, which will be described later, estimates the indoor temperature using a fluid model, if the entire operation time of the air conditioner 100 is calculated, the amount of calculation will be large and the calculation time will be long. The representative temperature estimating unit 20 uses a thermal energy model of the room 200 to estimate the room temperature at the initial stage of the air conditioner 100 in order to reduce the amount of calculation and shorten the calculation time.

Here, the thermal energy model is a model for estimating the room temperature from the thermal energy of the room 200 . The thermal energy model has T d as the relative temperature of the outdoor temperature T _out to the indoor temperature T _in , that is, the temperature difference, _t as the elapsed time from the start of operation of the air conditioner 100, R as the thermal resistance from the indoor to the outdoor, and C is the heat capacity of the indoor unit, Q is the amount of heat that the indoor unit supplies to the room, that is, diffuses indoors, ρ is the density of the air, _{C is} the specific heat of the air, and _{A is} the air volume that the indoor unit blows into the room. When the temperature of the wind is T _W and the room temperature is T _in , they are represented by the following Equations 1 and 2.

The units of heat capacity C, heat resistance R, and heat quantity Q in Equation 1 are W/°C, °C/W, and W. The unit of the temperature difference _Td is degrees Celsius. The units of air density ρ, air specific heat C _p , and air volume A _q in Equation 2 are kg/m ³ , (W·s)/(kg·°C), and m ³ /sec. The units of the air temperature T _W and the room temperature T _in are both degrees Celsius. The unit of elapsed time t in Equations 1 and 2 is seconds.

In addition, the thermal resistance R and the thermal capacity C in Equation 1 are expressed as follows, where h is the thermal conductivity of the wall of the room 200, S is the wall area of the room 200, c is the specific heat of the wall, and _{Vo is} the volume of the wall. is represented by Equations 3 and 4 of

Here, the units of thermal conductivity h and wall area S in Equation 3 are W/(m ² ·°C) and m ² . The unit of the specific heat c of the wall and the volume V _o of the wall in Expression 4 is W/(°C·m ³ ), m ³ .

The representative temperature _estimating unit 20 using this thermal energy model will be described in detail. Get the indoor temperature and outdoor temperature at the time. Then, the representative temperature estimator 20 subtracts the outdoor temperature from the indoor temperature to obtain the initial value of the temperature difference _Td of the thermal energy model. Also, the representative temperature estimating unit 20 sets the acquired room temperature as the room temperature T _in of the thermal energy model.

The representative temperature estimator 20 also receives the wind characteristic parameters from the parameter identifier 10 in order to obtain the initial values of the air volume A _q and the wind temperature _TW of the thermal energy model. The representative temperature estimator 20 sets the air volume and the wind temperature of the wind characteristic parameters to the air volume A _q and the wind temperature _TW of the thermal energy model.

The storage unit 50 stores thermal conductivity data including wall thermal conductivity, wall area, wall specific heat, wall volume, air density, and air specific heat of the room 200 in which the indoor unit 130 is installed, as shown in FIG. 52 are stored. The representative temperature estimating unit 20 reads the heat conduction data 52 from the storage unit 50 in order to obtain the air density ρ and the air specific heat _Cp of the thermal energy model. Then, the representative temperature estimating unit 20 sets the air density and air specific heat data included in the read heat conduction data 52 as the air density ρ and air specific heat C _p of the thermal energy model.

In addition, the representative temperature estimator 20 uses the thermal conductivity of the wall, the area of the wall, the specific heat of the wall, and the volume of the wall included in the read heat conduction data 52 and Equations 3 and 4 to calculate the thermal resistance and the heat capacity. Ask for Then, the representative temperature estimator 20 sets the determined thermal resistance and thermal capacity as the thermal resistance R and thermal capacity C of the thermal energy model.

The representative temperature estimating unit 20 uses each parameter such _as the obtained temperature difference T _d and the obtained T _in and a thermal energy model to determine the time t ₁ , the temperature difference T _d (t ₁ ) between the indoor temperature T _in and the outdoor temperature T _out is obtained. The representative temperature estimator 20 adds the outdoor temperature T _out to the temperature difference T _d (t ₁ ) thus obtained to obtain the indoor temperature T _in (t ₁ ) after a certain period of time has elapsed. The representative temperature estimating unit 20 sets the determined indoor temperature T _in (t ₁ ) as a representative temperature representing the indoor temperature, and transmits the representative temperature to the temperature distribution estimating unit 30 .

The temperature distribution estimator 30 is a part that estimates an accurate indoor temperature distribution after the room temperature estimated by the representative temperature estimator 20 . The temperature distribution estimating unit 30 uses a fluid model of indoor air to estimate an accurate temperature distribution. Thereby, the temperature distribution estimator 30 estimates the indoor temperature distribution at the time after the representative temperature estimator 20 estimates. Note that the temperature distribution estimator 30 is an example of the indoor temperature distribution estimator referred to in this specification.

Here, the fluid model is a model for estimating the indoor temperature distribution by estimating the temperature at any location in the room from the flow of air in the room and the thermal energy of the air. The fluid model is expressed by the following Equations 5 to 8, where p is the air pressure in the room, V=(u, v, w) is the air flow velocity vector, and T _in is the room temperature.

Note that Re in Equations 5 and 6 is the Reynolds number. Pr in Equation 6 is the Prandtl number.

The temperature distribution estimator 30 determines the temperature estimation locations in the room 200 in order to estimate the temperature distribution using the fluid model described above. Specifically, the storage unit 50 stores room data 53 including three-dimensional data of the room 200 shown in FIG. The temperature distribution estimation unit 30 reads the room data 53 and obtains the shape and size of the room 200 from the three-dimensional data of the room 200 in the read room data 53 . Based on the obtained shape and size, the temperature distribution estimating unit 30 obtains the center coordinates of each cell 210 when the room 200 shown in FIG. 15 is partitioned into cubic cells 210 . Thereby, the temperature distribution estimation unit 30 determines the temperature estimation locations in the room 200 . The center coordinates of each cell 210 are hereinafter referred to as cell coordinates.

In order to determine the initial value of the indoor temperature T _in of the fluid model represented by Equations 5 to 8, the temperature distribution estimating unit 30 also receives from the representative temperature estimating unit 20 the indoor representative temperature obtained by the thermal energy model. to get Then, the temperature distribution estimating section 30 assigns the representative temperature obtained from the temperature distribution estimating section 30 to the coordinates of each cell 210 described above. Accordingly, the temperature distribution estimator 30 assumes that the air temperature of all the cells 210 is the representative temperature obtained from the temperature distribution estimator 30 . Thereby, the temperature distribution estimator 30 determines the initial value of the temperature T _in of the fluid model for all the cells 210 .

Furthermore, the temperature distribution estimator 30 determines boundary conditions and an initial value of the air flow velocity vector V of the fluid model in each cell 210 .

Specifically, the room data 53 shown in FIG. Contains location data. The temperature distribution estimator 30 reads the air outlet position data and the air inlet position data from the room data 53, and from the data, specifies the cell coordinates of the cell 210 where the air outlet and the air inlet are arranged.

The temperature distribution estimator 30 also receives wind characteristic parameters, that is, data on the air volume, wind direction, and wind speed of the outlet from the parameter identifier 10 . On the other hand, the storage unit 50 contains outlet air distribution data indicating the air distribution in the vicinity of the outlet and suction outlet air distribution data indicating the air distribution in the vicinity of the air outlet obtained by experiments. Distribution data 54 are stored. The temperature distribution estimating section 30 reads the indoor airflow distribution data 54 from the storage section 50 .

Here, as described above, the parameter specifying unit 10 uses the wind characteristic parameters, that is, the data of the air volume, the wind direction, and the wind speed of the air blown out from the outlet, as the air volume, the wind direction, and the air conditioning conditions in the data table 51 . and wind speed. On the other hand, the indoor unit airflow distribution data 54 stores outlet airflow distribution data and intake airflow distribution data for each combination of airflow, wind direction and wind speed in the data table 51 at that air volume, wind direction and wind speed. It is

The temperature distribution estimating unit 30 corresponds to the received data of the air volume, wind direction and wind speed of the outlet based on the data of the air volume, wind direction and wind speed of the outlet received from the parameter specifying unit 10 and the read indoor unit wind distribution data 54 . Identify the outlet draft distribution data and the inlet draft distribution data. Then, the temperature distribution estimating unit 30 uses the specified air outlet air distribution data and air inlet air distribution data and the above-mentioned cell coordinates where the air outlet and the air inlet are arranged to determine the air outlet and the air inlet. The wind direction and wind speed of the cells 210 located nearby are obtained.

The temperature distribution estimator 30 obtains an air flow velocity vector V from the obtained wind direction and wind velocity, and assigns the flow velocity vector V to the cell coordinates of the cells 210 located near the air outlet and the air inlet. Moreover, the temperature distribution estimation unit 30 assigns a flow velocity vector V with a magnitude of 0 to the cell coordinates of the cells 210 other than those near the outlet and the suction port. As described above, the temperature distribution estimating unit 30 obtains the initial value of the flow velocity vector V and the boundary conditions of the fluid model represented by Equations 5 to 8 for all the cells 210 .

The temperature distribution estimator 30 also obtains the pressure p of the fluid model in each cell 210 . Specifically, the temperature distribution estimator 30 obtains the dynamic pressure from the magnitude of the flow velocity of the allocated flow velocity vector V for each cell 210 . Then, the temperature distribution estimator 30 obtains the total pressure of each cell 210, that is, the pressure p, with the static pressure being 1 atmospheric pressure. The temperature distribution estimator 30 assigns the determined pressure p of each cell 210 to the cell coordinates of each cell 210 . Thereby, the temperature distribution estimator 30 obtains the initial value of the pressure p of the fluid model for all the cells 210 .

The temperature distribution estimating unit 30 uses the temperature T _in of each cell 210, the flow velocity vector V, and the pressure p obtained in the above process as initial values, and solves the equations 5 to 8 for all the cells 210 to obtain the value at the target time. obtain the temperature of the air in each cell 210 of . Thereby, the temperature distribution estimator 30 obtains the indoor temperature distribution at the target time. The temperature distribution estimator 30 transmits the obtained temperature distribution, that is, the air temperature of all the cells 210 to the air conditioning condition adjuster 40 .

The temperature distribution estimating unit 30 calculates only the time obtained by subtracting the fixed time calculated by the representative temperature estimating unit 20 from the target time. Time is an example. Also, the temperature distribution estimator 30 is an example of the indoor temperature distribution estimator referred to in this specification.

The air-conditioning condition adjustment unit 40 receives the air temperature data of all the cells 210 from the temperature distribution estimation unit 30, and the air temperature of the cell 210 at the set position among all the cells 210 reaches the target time. to determine whether or not it is within the permissible range from the set temperature.

Specifically, the air conditioning condition adjustment unit 40 acquires setting data from the indoor unit control unit 150 via the wireless communication modules 60 and 151 . In addition, as shown in FIG. 10, the storage unit 50 stores determination data 55 including the coordinates of a specific position in the room where the room temperature should be determined and the threshold value of the temperature difference between the room temperature and the set temperature. remembered. The air-conditioning condition adjustment unit 40 reads the determination data 55 from the storage unit 50 and identifies the cell 210 including the specific position based on the coordinates of the specific position in the read determination data 55 . The air-conditioning condition adjustment unit 40 obtains the absolute value of the temperature difference between the specified room temperature of the cell 210 and the set temperature included in the acquired set data. The air-conditioning condition adjustment unit 40 determines whether or not the obtained absolute value exceeds the threshold.

When determining that the absolute value exceeds the threshold, the air conditioning condition adjustment unit 40 calculates the temperature difference between the set temperature and the room temperature of the cell 210, and adjusts the set temperature based on the calculated temperature difference. fix it. For example, the air conditioning condition adjusting unit 40 raises or lowers the set temperature by the temperature difference. Then, the air conditioning condition adjusting unit 40 transmits the corrected set temperature to the indoor unit control unit 150 via the wireless communication modules 60 and 151 .

Further, when determining that the absolute value does not exceed the threshold value, the air conditioning condition adjustment unit 40 does not transmit data to the indoor unit control unit 150 .

Indoor unit control section 150 controls the rotation speed of fan 132 based on the corrected set temperature received from air conditioning condition adjustment section 40 . Also, the indoor unit controller 150 transmits the corrected set temperature to the outdoor unit controller 160 . Thereby, the outdoor unit control unit 160 controls the rotation frequency of the motor 125 provided in the compressor 121, the opening degree of the expansion valve 124, and the rotation speed of the fan 126 based on the corrected set temperature. As a result, the air conditioning of the air conditioner 100 is adjusted more accurately.

As shown in FIG. 12, the control device 1A includes a CPU (Central Processing Unit) 300 and an I/O port (Input/Output Port) 310 to which the wireless communication module 60 is connected. The storage unit 50 also stores an air conditioner control program. The parameter identifying unit 10, the representative temperature estimating unit 20, the temperature distribution estimating unit 30, and the air conditioning condition adjusting unit 40 described above are realized by the CPU 300 executing the air conditioner control program stored in the storage unit 50. there is

Next, the operation of the control device 1A will be described with reference to FIGS. 13 and 14. FIG. In the following description, the control device 1A is realized using an information processing device such as a personal computer or a server, which is connected to the air conditioner 100 via the network 70 and has a CPU 300 and an I/O port 310. and

FIG. 13 is a flowchart of the air conditioner control process performed by the control device 1A. FIG. 14 is a conceptual diagram of cells when estimating the temperature distribution in the air conditioner control process.

When the air conditioner control program is started up in the information processing apparatus described above, the air conditioner control program is executed by the CPU 300 . As a result, the flow of the air conditioner control process is started.

When the flow of the air conditioner control process is started, first, as shown in FIG. 13, the control device 1A determines whether the indoor unit control section 150 has received setting data (step S1). Specifically, the indoor unit control section 150 transmits a setting data reception completion signal to the control device 1A each time the remote controller 140 transmits setting data. The control device 1A determines whether or not this setting data reception completion signal has been received.

When the controller 1A determines that the indoor unit controller 150 has not received the setting data (No in step S1), the process returns to before step S1.

On the other hand, when the control device 1A determines that the indoor unit control unit 150 has received the setting data (Yes in step S1), the air conditioning conditions of the outdoor unit 120 and the indoor unit 130, that is, the four-way valve provided in the outdoor unit 120 122 switching direction, the rotation frequency of the compressor 121, the degree of opening of the expansion valve 124, the rotation speed of the fan 126, the rotation speed of the fan 132 provided in the indoor unit 130, and the inclinations of the wind direction control plates 133 and 134 are acquired. Further, the control device 1A acquires the indoor temperature T _in and the outdoor temperature T _out (step S2).

Subsequently, the control device 1A determines the wind characteristic parameter of the air blown by the indoor unit 130 (step S3). Specifically, the control device 1A reads out the data table 51 from the storage unit 50, and based on the data table 51 and the air conditioning conditions, the indoor temperature, and the outdoor temperature acquired in step S2, the airflow of the indoor unit 130 is determined. Identify characteristic parameters. It should be noted that steps S2 and S3 are an example of parameter identification steps referred to in this specification.

After determining the wind characteristic parameter, the control device 1A estimates the representative temperature in the room using the thermal energy model (step S4).

Specifically, the control device 1A reads the heat conduction data 52 from the storage unit 50, and uses the read heat conduction data 52 to calculate the thermal resistance R from indoors to outdoor and the indoor heat capacity C of Equations 3 and 4. Calculate The control device 1A converts the calculated thermal resistance and heat capacity, the indoor temperature T _in and the outdoor temperature T _out obtained in step S2, and the wind characteristic parameter determined in step S3 to formulas 1 and 2 of the thermal energy model described above. , the temperature difference T _d (t ₁ ) between the indoor temperature T _in and the outdoor temperature T _out at time t ₁ after a certain period of time has passed since the start of operation of the air conditioner 100 is calculated.

Here, the fixed time is set to a time shorter than the target time for which temperature estimation is desired. For example, if the target time is 1 or 2 hours, the fixed time is 30 minutes or 1 hour. In order to shorten the overall calculation time of the representative temperature estimating section 20 and the temperature distribution estimating section 30, it is desirable that the certain time is sufficiently long enough to saturate the temperature difference T _d (t ₁ ). For example, it is desirable that the certain time is 2 to 3 times the time constant represented by the product of the thermal resistance R and the thermal capacity C expressed by Equations 3 and 4. It should be noted that the certain period of time is an example of the first period of time referred to in this specification.

The temperature difference T _d (t ₁ ) calculated using the thermal energy model is the relative temperature of the outdoor temperature T _out (t ₀ ) to the indoor temperature T _in as described above. Therefore, the control device 1A adds the outdoor temperature T _out (t ₀ ) obtained in step S2 to the calculated temperature difference, and calculates the indoor temperature T _in (t ₁ ) after a certain period of time has passed since the start of operation. Calculate Then, the control device 1A sets the room temperature T _in (t ₁ ) as a representative temperature representing the room. Thereby, the control device 1A estimates the representative temperature. Note that step S4 is an example of the representative temperature estimation step referred to in this specification.

Subsequently, the control device 1A estimates the indoor temperature distribution using the fluid model (step S5).

More specifically, the control device 1A solves the above-described Equations 5 to 8 using the MAC (Marker And Cell) method to estimate the temperature distribution. More specifically, the control device 1A reads the room data 53 from the storage unit, and based on the room data 53, obtains the central coordinates of each cell 210 when the room 200 is partitioned into cubic cells 210. .

Control device 1A assigns the representative temperature estimated in step S4 as the temperature of each cell 210 . Further, the control device 1</b>A uses the indoor unit airflow distribution data 54 stored in the storage unit 50 to find the air flow velocity vector for each cell 210 and assigns the found flow velocity vector to each cell 210 . Furthermore, the control device 1</b>A uses the indoor unit wind distribution data 54 stored in the storage unit 50 to obtain the air pressure for each cell 210 . The controller 1A assigns the obtained pressure to each cell 210. FIG.

Subsequently, the controller 1A uses the representative temperature, flow velocity vector, and pressure assigned to each cell 210 to solve Equations 5-8. Thereby, the control device 1A calculates the temperature of all the cells 210 after the predetermined time in step S4 has elapsed since the operation of the air conditioner 100 was started. Thereby, control device 1A obtains the temperature of all cells 210 when the target time has elapsed.

In this calculation, the control device 1A should desirably set the size of the cells 210 assuming that they are divided into cells 210 smaller than each part of the human body, such as the head, body, and legs. For example, the control device 1A obtains the central coordinates of each cell 210 on the assumption that the room 200 is partitioned by cubes each side of which is 20 cm.

Further, the control device 1A performs calculation at the time step Δt at which the Courant number represented by Equation 9 is 1 or less. For example, the control device 1A sets the time step Δt to 0.04 seconds or less when the cell size is 20 cm and the wind speed of the outlet of the indoor unit 130 is 5 m/sec.

If there are three-dimensional objects such as furniture and refrigerators in the room 200, the three-dimensional objects are assumed to be the inner wall shape of the room 200, and the three-dimensional data of the room 200 having the three-dimensional object as the inner wall shape is stored in the room data 53 in advance. It is good if it is registered with 50. In this case, as shown in FIG. 14, the control device 1A should assume that a room 200 having three-dimensional objects as inner walls is divided into cubic cells 210, and obtain the center coordinates of each cell 210. FIG. Further, step S5 is an example of the indoor temperature distribution estimation step referred to in this specification.

After estimating the temperature distribution in the room, the control device 1A determines whether the difference between the temperature at a specific position in the room and the set temperature exceeds a threshold (step S6). Specifically, the control device 1A reads out the determination data 55 from the storage unit 50, and from the coordinates of the specific position included in the determination data 55, identifies the cell 210 including the coordinates. The control device 1A obtains the absolute value of the temperature difference between the room temperature of the cell 210 and the set temperature, and determines whether or not the absolute value of the temperature difference exceeds the threshold.

When the control device 1A determines that the absolute value of the temperature difference exceeds the threshold value (Yes in step S6), the relative temperature of the room temperature with respect to the set temperature of the cell 210, that is, the temperature difference is calculated. , the set temperature data is corrected by the temperature difference (step S7). Subsequently, the control device 1A transmits the corrected set temperature data to the indoor unit 130 (step S8). After that, the control device 1A terminates the air conditioner control process. Note that steps S6 to S8 are an example of the air conditioning condition adjustment step referred to in this specification.

On the other hand, if it is determined that the absolute value of the temperature difference does not exceed the threshold (No in step S6), the control device 1A determines that the indoor temperature is within the allowable range from the set temperature, and does not correct the set temperature data. Then, the control device 1A terminates the current air conditioner control process, prepares for the user to input the next setting data to the remote controller 140, and returns to step S1.

In step S7, the controller 1A corrects the set temperature data by the temperature difference between the set temperature and the room temperature. However, the operation of the control device 1A is not limited to this, and the control device 1A may correct the set air volume data based on the temperature difference between the set temperature and the room temperature. In this case, the relationship between the set air volume before correction, the set temperature, the temperature difference, and the air volume to be set should be obtained by experiment, and the data table created from the experiment should be stored in advance in the storage unit 50 . Based on the data table, the set air volume, the set temperature, and the temperature difference, the control device 1A should correct the set air volume data.

Further, in step S7, if there is a temperature difference between the set temperature and the room temperature and the set wind direction is not in the direction from the air outlet of the indoor unit 130 toward the specific position in step S6, the control device 1A changes the set wind direction to that direction. You can correct the direction.

The flow of the air conditioner control process continues until the air conditioner control program is stopped by the information processing device described above. Thereby, the control device 1A continues the simulation of the temperature distribution in the room and the adjustment of the setting data based on the simulation result.

As described above, the control device 1A according to Embodiment 1 includes the representative temperature estimating unit 20 using the thermal energy model and the temperature distribution estimating unit 30 using the fluid model. distribution can be estimated.

In addition, since the air conditioning condition adjustment unit 40 corrects the set temperature data using the estimated indoor temperature distribution, the air conditioner 100 can perform air conditioning more accurately.

(Embodiment 2)
The control device 1A according to Embodiment 1 corrects the set temperature based on the temperature difference between the estimated room temperature and the set temperature. However, the control device 1A is not limited to this. The control device according to Embodiment 2 calculates the sensible temperature from the estimated room temperature, and corrects the set temperature data based on the difference between the calculated sensible temperature and the set temperature. Hereinafter, a control device according to Embodiment 2 will be described with reference to FIG. 15 . In addition, in Embodiment 2, a configuration different from that in Embodiment 1 will be described.

FIG. 15 is a block diagram of remote controller 190 included in air conditioner 100 controlled by the control device according to Embodiment 2. As shown in FIG.

As shown in FIG. 15, the remote controller 190 has adjustment setting buttons 196 . The adjustment setting button 196 is a button for turning on and off an adjustment mode in which the control device adjusts the room temperature to the sensible temperature. When the adjustment setting button 196 is pressed, the remote controller 190 transmits ON/OFF of the adjustment mode to the indoor unit control section 150 .

In the control device, the air conditioning condition adjustment unit 40 receives the ON/OFF of the adjustment mode from the indoor unit control unit 150 .

On the other hand, as described in Embodiment 1, the temperature distribution estimator 30 calculates the flow velocity vector of the air in the room when estimating the temperature distribution using the fluid model. Therefore, the temperature distribution estimator 30 not only estimates the room temperature at the target time, but also estimates the flow velocity vector at the target time. Thereby, the temperature distribution estimator 30 estimates the wind speed.

When the air conditioning condition adjusting unit 40 determines that the absolute value of the temperature difference between the room temperature estimated by the temperature distribution estimating unit 30 and the set temperature exceeds the threshold when the adjustment mode is on, the temperature distribution From the room temperature and the wind speed estimated by the estimation unit 30, the sensible temperature of a person in the cell 210 at the determined specific position is calculated. For calculating the sensible temperature, the Linke equation is used because the temperature distribution estimator 30 does not predict the humidity. Here, the Linke's formula is a formula for obtaining the sensible temperature from wind speed and air temperature.

The air conditioning condition adjustment unit 40 obtains the relative value of the calculated sensible temperature to the set temperature, and corrects the set temperature data according to the obtained relative value. Specifically, the air conditioning condition adjusting unit 40 raises or lowers the set temperature by a relative value.

The air conditioning condition adjusting unit 40 transmits the corrected set temperature data to the indoor unit control unit 150 . As a result, the control device brings the temperature of air present at a specific position in the room close to the sensible temperature.

As described above, the control device according to Embodiment 2 calculates the sensible temperature at a specific position from the indoor temperature and the wind speed estimated by the temperature distribution estimation unit 30, and based on the sensible temperature, the air conditioner 100 It has an air conditioning condition adjustment unit 40 that adjusts the set temperature. Therefore, the control device can bring the indoor temperature closer to the sensible temperature when the air conditioner 100 performs air conditioning. As a result, the controller can enhance user comfort.

For example, in Embodiments 1 and 2, the air-conditioning condition adjusting unit 40 determines the room temperature at a specific position in the room 200 estimated by the temperature distribution estimating unit 30 and the set temperature set by the remote controllers 140 and 190. The set temperature, that is, the set data is adjusted according to the difference between .

However, the air conditioning condition adjustment unit 40 is not limited to this. The air-conditioning condition adjusting unit 40 may adjust the air-conditioning conditions of the indoor unit 130 and the outdoor unit 120 according to the temperature difference without using the setting data. That is, the air conditioning condition adjustment unit 40 adjusts the rotation frequency of the compressor 121, the opening degree of the expansion valve 124, the rotation speed of the fan 126, the rotation speed of the fan 132 provided in the indoor unit 130, and the inclination of the wind direction control plates 133 and 134. can be adjusted directly.

For example, data that associates the above difference and setting data with the rotation frequency of the compressor 121 to be corrected, the opening degree of the expansion valve 124, the rotation speeds of the fans 126 and 132, and the inclinations of the wind direction control plates 133 and 134. is preferably stored in the storage unit 50 . Then, the air conditioning condition adjustment unit 40 reads this data from the storage unit 50, and based on this data, determines the rotation frequency of the compressor 121, the opening degree of the expansion valve 124, the rotation speeds of the fans 126 and 132, and the wind direction control plate. The slopes of 133 and 134 may be obtained. Furthermore, the air conditioning condition adjustment unit 40 may transmit the obtained conditions to the indoor unit control unit 150 or the outdoor unit control unit 160 .

In Embodiments 1 and 2, the air conditioning condition adjustment unit 40 adjusts the setting data using the indoor temperature at a specific position in the room 200 . However, the air conditioning condition adjustment unit 40 is not limited to this. The air-conditioning condition adjustment unit 40 may adjust the setting data using a representative value, which is a numerical value that serves as a measure of the temperature distribution in the room 200 .

FIG. 16A is a conceptual diagram of areas A1 and A2 of room 200 for which representative values are obtained when air-conditioning condition adjusting section 40 adjusts setting data. FIG. 16B is a graph showing changes in average temperature in each region A1 and A2. Note that FIG. 16B shows changes in the estimated indoor temperature during the period P1 during which the representative temperature estimating unit 20 estimates the indoor temperature in the initial stage and the subsequent period P2 during which the temperature distribution estimating unit 30 estimates the indoor temperature. . The estimated indoor temperature is the average temperature of the entire room 200 during period P1. In the period P2, the temperature distribution estimator 30 estimates the temperature distribution in the room, and in FIG. 16B, the temperature distribution is converted into an average temperature T1 of the area A1 and an average temperature T2 of the area A2.

The air-conditioning condition adjusting unit 40 may obtain the average temperature shown in FIG. 16B as a representative value of the indoor temperature distribution of the area A1 or A2 when the room 200 shown in FIG. 16A is divided into two areas A1 or A2. . Then, the air conditioning condition adjusting section 40 may adjust the set temperature according to the difference between the obtained average temperature and the set temperature set by the remote controllers 140 and 190 . In this case, the storage unit 50 preferably stores division data of the room 200 and region designation data indicating which region's average temperature is used to adjust the set temperature. Based on these data, the temperature distribution estimating section 30 of the air conditioning condition adjusting section 40 preferably determines the area and obtains the average temperature of the determined area. Note that the representative value of the indoor temperature distribution is, for example, the median value and the maximum value of the indoor temperature distribution in addition to the average temperature.

In Embodiments 1 and 2, control devices 1A and 1B cause representative temperature estimating section 20 to estimate the representative temperature, and then directly output the representative temperature to temperature distribution estimating section 30. Temperature distribution estimating section 30 The representative temperature is used to estimate the indoor temperature distribution. However, the control devices 1A and 1B are not limited to this. The control devices 1A and 1B may further include a calculation management section that causes the representative temperature estimating section 20 to calculate for a specified time and inputs the representative temperature estimated by the representative temperature estimating section 20 to the temperature distribution estimating section 30 . Here, the specified time is the time specified by the calculation management unit, and has a period corresponding to the fixed time described in the first embodiment.

In Embodiments 1 and 2, the parameter specifying unit 10 uses the data table 51 to specify the air conditioning conditions of the outdoor unit 120 and the indoor unit 130, the indoor temperature, and the wind characteristic parameters corresponding to the outdoor temperature data. .

For example, when the indoor unit 130 operates under specific air conditioning conditions with respect to the temperature difference between the indoor temperature and the outdoor temperature, the parameter identifying unit 10 determines the wind volume, wind direction, and temperature for the specific air conditioning conditions. The parameters may be specified using an approximation function that represents. In this case, it is preferable that an approximation function representing the air volume, wind direction, and temperature for the air conditioning conditions of the indoor unit 130 is obtained in advance by experiment, and the obtained approximation function is stored in the storage unit 50 . Then, the parameter specifying unit 10 preferably reads the approximation function from the storage unit 50 .
