Warm air or cold air generated by a heat source is led to each room through a duct by a fan to perform air conditioning (see Patent Document 1). However, in such an air conditioning system, since temperature measurement is performed only in one room with a thermostat, the heat load situation for each room (the amount of solar radiation, the heat load due to indoor facilities, etc.) is not considered. Therefore, there is an individual air conditioning system using an individual distributed air conditioner that provides an air conditioning environment that takes into account the thermal load status of each room.

<< First Embodiment >>
<Overall configuration of air conditioning system>
FIG. 1 shows an air conditioning system 1 according to a first embodiment of the present invention. This air conditioning system 1 is mainly composed of an intermediary device 310a-310c, a thermostat 320a-320c as an air conditioning interface, an outdoor unit 330 having a heat source, and an indoor unit 340a-340c for performing individual air conditioning. Yes. The outdoor unit 330 and the indoor units 340a to 340c are connected via a refrigerant path 333 and a communication line 334. The air conditioner is communicably connected to the mediation devices 310a to 310c via the communication line 335. The two types of communication lines 334 and 335 may be the same type of communication line or different types of communication lines. Further, the intermediary devices 310a to 310c are connected to the thermostats 320a to 320c through control lines. Specifically, as shown in FIG. 1, the intermediary devices 310a-310c are connected to the indoor units 340a-340c on a one-to-one basis. In this embodiment, an example in which an individual air conditioner is most easily introduced is given as a form of introducing an individual air conditioner into a central air conditioning facility using an air conditioning interface such as a thermostat. Hereinafter, the configuration of each unit will be described.

<Function of thermostat>
First, the function of the thermostat 320a-320c will be described.

  FIG. 2A shows an example of the display part of the thermostat 320a-320c. The thermostats 320a to 320c are often used as an air conditioning control interface particularly in homes in Europe and the United States, and have a room temperature holding function, a set temperature setting function, a fan ON / OFF setting function, a cooling / heating setting function, and the like. The thermostats 320a to 320c realize the above-described functions by being operated according to the display interface as shown in FIG. 2A. The thermostats 320a to 320c are compressors provided in the outdoor unit 330 based on the set temperature set by the user and the temperature (corresponding to the first room temperature value) measured by the temperature sensor provided therein. A control signal (operation / non-operation request signal) for requesting operation or non-operation of operation is generated for (not shown). For example, when the air conditioner is operating in a cooling operation and the room temperature detected by the temperature sensor is higher than the set temperature set by the user, the thermostat 320a-320c sends an operation / non-operation request signal requesting operation. On the contrary, when the room temperature detected by the temperature sensor is lower than the set temperature, an operation / non-operation request signal for requesting non-operation is generated.

  FIG. 2B is a table showing correspondence between signals output from thermostats 320a to 320c and operation modes. Thermostats 320a-320c output signals (fan ON / OFF, heating operation, auxiliary heater ON / OFF, compressor ON / OFF, emergency heat ON, heating ON, cooling ON, etc.) as shown in FIG. 2B. Among these, the intermediary device described later includes a compressor ON / OFF signal (Y signal), a cooling / heating signal (cooling signal (O signal) and heating signal (B signal), or cooling / heating signal (O / B signal)), Using fan ON / OFF signal (G signal), operation / stop, operation mode (cooling, heating, air blowing), set temperature, air volume (strong, weak, Auto), capacity control (100%, 70%, 40%) , 0%), etc., can be used to control individual distributed air conditioners.

<Schematic configuration of air conditioner>
The outdoor unit 330 and the indoor units 340a to 340c are air conditioners for realizing individual air conditioning. Individual air conditioning for each room is performed by adjusting the flow rate of the refrigerant sent from the outdoor unit 330 via the refrigerant path 333. Each indoor unit 340a-340c is provided with a suction temperature sensor 341a-341c. Suction temperature sensors 341a-341c measure a suction temperature value (corresponding to a second room temperature value) when each indoor unit 340a-340c sucks indoor air into the casing. Furthermore, each of the indoor units 340a to 340c adjusts the flow rate of the refrigerant by adjusting the valve opening degree according to the air conditioning target temperature value transmitted from the intermediary device 310a to 310c connected thereto. The air conditioning target temperature value is a parameter used when the indoor units 340a to 340c operate. The indoor units 340a to 340c are controlled so that the indoor environment becomes the air conditioning target temperature value. The mediating devices 310a-310c will be described below.

<Configuration of mediation device>
Intermediary devices 310a-310c receive control signal inputs from thermostats 320a-320c, convert the signals into predetermined signals described later, and transmit the signals to indoor units 340a-340c. Since all of the mediation devices 310a to 310c have the same configuration, the mediation device 310a will be described below with reference to FIG. The intermediary device 310 a includes a reception unit 311, a storage unit 312, a control unit 313, and a transmission unit 314. The receiving unit 311 receives an input of a control signal from the thermostat 320a and receives an input signal from an air conditioner. Signals received by the receiving unit 311 from the air conditioner include those related to the suction temperature value acquired by the room temperature acquiring unit 313a described later. The control signal received by the receiving unit 311 from the thermostat 320a includes the above-described compressor ON / OFF (Y signal), cooling / heating signal (cooling signal (O signal) and heating signal (B signal), or cooling / heating signal ( O / B signal)) and fan ON / OFF signal (G signal).

  The storage unit 312 includes an internal memory such as a RAM and a ROM, and an external memory such as a hard disk. The storage unit 312 stores a control program 312a for executing control processing by an intermediary device 310a described later. Furthermore, a predetermined temperature value storage area 312b and an air conditioning target temperature value storage area 312c are secured in the storage unit 312. In the predetermined temperature value storage area 312b, a suction temperature value acquired by a room temperature acquisition unit 313a described later when the receiving unit 311 receives an input of an operation / non-operation request signal, or an upper limit during cooling operation as an initial value A value (for example, 35 ° C.) and a lower limit value for heating operation (for example, 15 ° C.) are stored. Specifically, a predetermined temperature as an initial value is stored in the predetermined temperature value storage area 312b at the start of operation, but the receiving unit 311 is activated / non-activated in the predetermined temperature value storage area 312b after the start of operation. The suction temperature value acquired by the room temperature acquisition unit 313a when the input of the operation request signal is received is stored. The suction temperature value stored in the predetermined temperature value storage area 312b is overwritten each time the room temperature acquisition unit 313a acquires the suction temperature value. The air conditioning target temperature value storage area 312c stores air conditioning target temperature values determined by a parameter determination unit 313b described later and transmitted to the air conditioner.

  The control unit 313 mainly includes a room temperature acquisition unit 313a and a parameter determination unit 313b, and is configured by a CPU or the like. The room temperature acquisition unit 313a acquires the suction temperature value detected by the suction temperature sensor 341a from the indoor unit 340a after the reception unit 311 receives the input of the operation / non-operation request signal. The parameter determination unit 313b determines a parameter used by the indoor unit 340a for operation based on the suction temperature value detected by the suction temperature sensor 341a. Specifically, the parameter determination unit 313b calculates an average value of the suction temperature value detected by the suction temperature sensor 341a and the value stored in the predetermined temperature value storage area 312b, and further, the air conditioning target temperature value storage area described above. The air conditioning target temperature value used for the operation of the indoor unit 340a is determined with reference to the value stored in 312c.

  For example, when the cooling operation is started, since the upper limit value (35 ° C. in the present embodiment) during the cooling operation is stored in the predetermined temperature value storage area 312b, the parameter determination unit 313b sets the upper limit value (35 ° C.) and An average value with a temperature value (for example, 20 ° C.) acquired by the room temperature acquisition unit 313a when the reception unit 311 receives an input of an operation / non-operation request signal requesting non-operation after the operation is started is calculated. After calculating the average value, the parameter determination unit 313b then compares the calculated average value with the value stored in the air conditioning target temperature value storage area 312c. Here, when the difference between the calculated average value and the value stored in the air conditioning target temperature value storage area 312c exceeds 0.5 ° C., the parameter determination unit 313b determines the average value as the air conditioning target temperature. The value is transmitted to the indoor unit 340a via a transmission unit 314 described later. When the difference between the average value and the value stored in the air conditioning target temperature value storage area 312c is within 0.5 ° C., it is stored in the air conditioning target temperature value storage area 312c for the indoor unit 340a. Send value. Therefore, the newly calculated value is not transmitted to the indoor unit 340a, and the indoor unit 340a maintains control at the current air conditioning target temperature value. As described above, the predetermined temperature value storage area 312b stores the suction temperature value acquired by the room temperature acquisition unit 313a when the reception unit 311 receives the input of the operation / non-operation request signal. Therefore, the air conditioning target temperature value calculated by the parameter determination unit 313b next is calculated using the suction temperature value acquired by the room temperature acquisition unit 313a and the temperature value stored in the predetermined temperature value storage area 312b. .

  The transmission unit 314 is used when transmitting a signal generated by the mediation device 310a, such as an air conditioning target temperature value as a parameter determined by the parameter determination unit 313b, to the indoor unit 340a.

<Processing flow of mediation device>
FIG. 4 shows the flow of the cooling operation of the air conditioner using the thermostats 320a to 320c. Here, the flow of processing in the mediation device 310a when the indoor unit 340a is operated using the thermostat 320a and the mediation device 310a will be described. In addition, as described above, the upper limit value (at the time of cooling operation) and the lower limit value (at the time of heating operation) are stored in advance in the predetermined temperature value storage area 312b as described above.

  First, the intermediary device 310a determines whether or not there is a change in the operation / non-operation request signal for the compressor input from the thermostat 320a (step S301). In this embodiment, a change in the compressor ON / OFF signal, that is, the Y signal that was set to ON is set to OFF, or conversely, the signal of the compressor that was previously set to OFF is set to ON. Determine whether it was done. If there is no change in the control signal, the process returns to the beginning. When it is determined in step S301 that there is a change in the Y signal, the parameter determination unit 313b determines that the temperature value M stored in the predetermined temperature value storage area 312b and the room temperature acquisition unit when there is a change in the Y signal. An average value (air conditioning target temperature value A) with the suction temperature value T of the suction temperature sensor 341a acquired by 313a is calculated (step S302).

  Next, the parameter determination unit 313b determines whether or not there is a value (stored value S) stored in the air conditioning target temperature value storage area 312c (step S303). Here, when the stored value S is stored in the air conditioning target temperature value storage area 312c, the parameter determination unit 313b compares the previously calculated air conditioning target temperature value A with the stored value S to determine the air conditioning target. It is determined whether or not the difference between the temperature value A and the stored value S is within 0.5 ° C. (step S304). Here, when the difference between the air conditioning target temperature value A and the stored value S is within 0.5 ° C., the stored value S is transmitted to the indoor unit 340a as the air conditioning target temperature value (step S306). On the other hand, if the stored value S is not stored in step 303 and if the difference between the air conditioning target temperature value A and the stored value S is greater than 0.5 ° C. in step S304, the air conditioning target temperature The value A is recorded as the stored value S in the air conditioning target temperature value storage area 312c (step S305), and the value stored in the air conditioning target temperature value storage area 312c is transmitted to the indoor unit 340a as the air conditioning target temperature value (step S306). After that, the temperature T of the suction temperature sensor grasped by the current room temperature acquisition unit 313a is recorded in the predetermined temperature value storage area 312b (step S307).

  FIG. 5 shows the ON / OFF state of the Y signal that changes in relation to the temperature (set temperature) set by the thermostat 320a during cooling operation and the room temperature grasped by the temperature sensor of the thermostat 320a, and the intermediary device when the Y signal changes The suction temperature value acquired at 310a and the air conditioning target temperature value A calculated based on the value (stored value M) stored in the predetermined temperature value storage area 312b are shown. As shown in the figure, when the room temperature exceeds the set temperature, the Y signal (Y signal ON) set to ON from the thermostat 320a is input to the intermediary device 310a, and set to OFF when the room temperature falls below the set temperature. Y signal (Y signal OFF) is input. When the Y signal is changed, the intermediary device 310a calculates the average value of the suction temperature value and the stored value M at that time, and sets it as the air conditioning target temperature value A. At this time, the intermediary device 310a calculates the calculated air conditioning target temperature value A, the previously calculated air conditioning target temperature value A, and the value (stored value S) stored in the air conditioning target temperature value storage area 312c. If the difference is within 0.5 ° C., the stored value S is commanded to the indoor unit 340a as the air conditioning target temperature value. That is, the air conditioning target temperature value is maintained in the indoor unit 340a.

<Characteristics of the air conditioning system according to the first embodiment>
(1) In the air conditioning system 1 according to the first embodiment, based on the control signal input from the thermostat 320a-320c, the mediation device 310a-310c is an air conditioning target temperature value as a parameter necessary for the individual air conditioning control of the air conditioner. Therefore, an individual air conditioner can be introduced using the existing air conditioning interface for central air conditioning, and a comfortable air conditioning environment corresponding to the unbalance of the air conditioning load can be provided.

  (2) When controlling an air conditioner using an existing air conditioning interface in a conventional air conditioning system, the air conditioner ON / OFF control is performed in synchronization with the ON / OFF signal generated by the air conditioning interface, and the cooling operation mode Then, the operation is performed at the lower limit value of the cooling operation mode and at the upper limit value of the heating operation mode in the heating operation mode, respectively. Then, when the ON / OFF signal of the air conditioning interface changes from ON to OFF or from OFF to ON, the energy load of the air conditioner is very large. In addition, comfort is not sufficient due to large temperature fluctuations. However, in the air conditioning system 1 according to the present embodiment, it is possible to operate an individual air conditioner that performs inverter control of the compressor by calculating the air conditioning target temperature value using an existing air conditioning interface. That is, by controlling the compressor with an inverter, the room temperature can be maintained at an approximate value of the room temperature desired by the user. Therefore, temperature fluctuations are reduced and the energy load of the air conditioner can be suppressed. Furthermore, the comfort of the indoor environment can be improved.

  (3) Although the output signal of the thermostat varies depending on the type, in this embodiment, the air conditioning target temperature value is determined using the basic output signal, and therefore, it can be applied to any type of thermostat.

  (4) In the air conditioning system 1 according to the present embodiment, the intermediary devices 310a to 310c determine the air conditioning target temperature value using values obtained by the suction temperature sensors 341a to 341c provided in the indoor units 340a to 340c. The suction temperature sensors 341a to 341c are sensors that a standard indoor unit has, and therefore it is not necessary to attach a new sensor separately, which is preferable in terms of appearance and cost.

  (5) In this embodiment, when the parameter determination unit 313b determines the air conditioning target temperature value A, the difference is over 0.5 ° C. compared with the value S stored in the air conditioning target temperature value storage area 312c. In this case, the newly calculated air conditioning target temperature value A is designed to be used for controlling the indoor units 340a to 340c. Thereby, since it is not necessary to frequently change the target temperature value in the indoor units 340a to 340c, the processing load of the air conditioner can be suppressed.

<Modification of First Embodiment>
(A) Although the cooling operation has been described as an example in the first embodiment, it can be similarly applied to the heating operation. In the heating operation, the suction air temperature value can be measured at the output timing of the control signal of the heater of the thermostat 320a-320c to determine the air conditioning target temperature value.

  (B) In the present embodiment, a plurality of thermostats 320a-320c and a plurality of mediation devices 310a-310c are connected to the indoor units 340a-340c on a one-to-one basis, and the thermostats 320a-320c converted by the mediation devices 310a-310c Individual air conditioning is performed by transmitting a control signal to one indoor unit 340a-340c connected to each unit. As shown in FIG. 6, one intermediary device and one thermostat are provided in the property. A control signal from the thermostat 320 that is installed and converted by the mediating device 310 may be transmitted to the indoor unit 340. In this case, the central control of the plurality of indoor units 340 can be performed using the thermostat 320. Further, in the air conditioning system in which one mediating device 310 and one thermostat 320 are provided in the property, as shown in FIG. 7, the control signal from the thermostat 320 converted by the mediating device 310 is transmitted to the outdoor unit 330. Also good. Also in this case, the central control of the plurality of indoor units 340 can be performed using the thermostat 320.

  (C) Each of the indoor units 340a to 340c may include a remote controller. When the remote control is set for the indoor units 340a-340c, the control of the indoor units 340a-340c can select either the air conditioning target temperature value based on the output signal from the thermostat 320 or the set temperature input by the individual remote control You may do it. Thereby, a comfortable air-conditioning environment can be realized flexibly.

  (D) In the present embodiment, the intermediary devices 310a to 310c determine the air conditioning target temperature value using the control signal (Y signal) for the compressor of the outdoor unit 330, but other output signals as shown in FIG. 2B. May be used to estimate the air conditioning target temperature value.

  (E) In the predetermined temperature value storage area 312b in the present embodiment, when a compressor ON / OFF signal (ON signal) set to ON is input to the intermediary device 310a-310c after the start of operation, the suction temperature at that time When the compressor ON / OFF signal (OFF signal) set to OFF is input after that, the suction temperature value at that time is overwritten and stored. That is, the air conditioning target temperature value is calculated based on any one of the suction temperature values or initial values stored in the storage unit 312 and the newly acquired suction temperature value. It is possible to store both the suction temperature value at the time of input and the suction temperature value at the time of input of the OFF signal, and after obtaining both values, the average value may be used as the air conditioning target temperature value.

  In addition, the air conditioning target temperature value determined by using the method described in the present embodiment or the air conditioning target temperature value determined by the method exemplified in Modification E is corrected, and the air conditioner is based on the corrected value. May be designed to operate. Furthermore, the air conditioning target temperature value obtained in this embodiment and this modification E may be averaged or moving average. That is, instead of using the obtained average value as it is, a value obtained by calculating the average value or moving average may be used as the air conditioning target temperature value.

  (F) In the flow described with reference to FIG. 4, the storage temperature S or the average value is commanded to the air conditioner as the air conditioning target temperature value, and then the suction temperature value T is recorded in the predetermined temperature value storage area 312b in step S307. The timing at which the suction temperature value T is stored in the predetermined temperature value storage area 312b may not be step S307. For example, it may be after step S302 or before step S306.

  In the present embodiment, after the air conditioning target temperature value is recorded as the stored value S in the air conditioning target temperature value storage area 312c in step S305, the value is transmitted to the indoor unit 340a as the air conditioning target temperature value in step S306. By adding a step of “send air conditioning target temperature value A to indoor unit 340a” before step S305 and executing step S307 after step S305, the air conditioning target temperature value is stored in the air conditioning target temperature value storage area 312c. The step of recording can be executed after the value is transmitted to the indoor unit 340a.

  In this embodiment, it is determined whether or not there is a value (stored value S) stored in the air conditioning target temperature value storage area 312c in step S303, but an initial value (for example, 0) is given in advance. It may be determined whether the stored value S is equal to an initial value (for example, 0).

  (G) In this embodiment, the mediating devices 310a to 310c determine parameters using Celsius (° C.), but Fahrenheit (° F.) may be used instead of Celsius.

  (H) In the air conditioning system 1 according to the present embodiment, the intermediary devices 310a to 310c determine the air conditioning target temperature value using the values of the suction temperature sensors 341a to 341c grasped by the indoor units 340a to 340c. 310a-310c can also determine the air conditioning target temperature value using a value obtained by another temperature sensor grasped by the indoor units 340a-340c instead of the suction temperature sensors 341a-341c. For example, the blowout temperature sensor of the indoor units 340a-340c, the temperature sensor of the remote controller connected to each of the indoor units 340a-340c, the remote sensor that is a temperature sensor provided extending from the main body of the indoor units 340a-340c, etc. The air conditioning target temperature can also be determined by using the value obtained by the above.

  The present invention has an effect of providing a comfortable air-conditioning environment that realizes individual air-conditioning and copes with imbalance of air-conditioning load by using an existing air-conditioning interface for central air-conditioning such as a thermostat. It is useful as an intermediary device, an air conditioning control system, an air conditioning control method, and an air conditioning control program.
