In this example, the outdoor unit 21 is provided with the expansion valve 53, but the present invention is not limited to this, and for example, the indoor unit 22 may be provided with the expansion valve 53.

(Indoor unit)
The indoor heat exchanger 61 exchanges heat between the air in the first space 5a (hereinafter, appropriately referred to as “indoor air”) supplied by the indoor blower 62 such as a fan and the refrigerant. As a result, heating air or cooling air, which is conditioned air supplied to the first space 5a, is generated. The indoor heat exchanger 61 functions as an evaporator that evaporates the refrigerant during the cooling operation and cools the indoor air by the heat of vaporization at that time. Further, the indoor heat exchanger 61 functions as a condenser that dissipates the heat of the refrigerant to the indoor air and condenses the refrigerant during the heating operation.

The low-temperature, low-pressure gas-liquid two-phase refrigerant that has flowed into the indoor heat exchanger 61 exchanges heat with the indoor air to absorb and evaporate, and becomes a low-temperature, low-pressure gas refrigerant that flows out of the indoor heat exchanger 61. The low-temperature low-pressure gas refrigerant flowing out of the indoor heat exchanger 61 passes through the refrigerant flow path switching device 52 and is sucked into the compressor 51.

(Heating operation mode)
In the heating operation mode, the refrigerant flow path switching device 52 is switched to the state shown by the broken line in FIG. Then, the low-temperature and low-pressure refrigerant is compressed by the compressor 51 and discharged as a high-temperature and high-pressure gas refrigerant. The high-temperature and high-pressure gas refrigerant discharged from the compressor 51 flows into the indoor heat exchanger 61 via the refrigerant flow path switching device 52.

The high-temperature and high-pressure gas refrigerant that has flowed into the indoor heat exchanger 61 exchanges heat with the indoor air taken in by the indoor blower 62, condenses while radiating heat, becomes a high-pressure liquid refrigerant, and flows out of the indoor heat exchanger 61. .. The high-pressure liquid refrigerant flowing out of the indoor heat exchanger 61 is depressurized by the expansion valve 53 to become a low-temperature low-pressure gas-liquid two-phase refrigerant, which flows into the outdoor heat exchanger 54.

The low-temperature, low-pressure gas-liquid two-phase refrigerant that has flowed into the outdoor heat exchanger 54 exchanges heat with the outdoor air, absorbs heat and evaporates, becomes a low-temperature, low-pressure gas refrigerant, and flows out of the outdoor heat exchanger 54. The low-temperature low-pressure gas refrigerant flowing out of the outdoor heat exchanger 54 passes through the refrigerant flow path switching device 52 and is sucked into the compressor 51.

Next, the centralized traffic control device 3 _{determines whether or not the temperature difference between the indoor temperature Ta} and the set temperature T _set in the first space 5a is lower than the preset temperature difference A (step S3). In this process, the cooling operation of the air conditioner 2, whether the indoor temperature T _a of the first space 5a has reached the set temperature T _set is determined. The temperature difference A at this time is set to, for example, about 0.5 ° C.

As a result of the determination, if the temperature difference between the indoor temperature _{T a} and the set temperature _{T set} of the first space 5a is lower than the temperature difference A; (step S3 YES), the process proceeds to step S4. On the other hand, when the temperature difference between the indoor temperature _{T a} and the set temperature _{T set} of the first space 5a is equal to or greater than the temperature difference A (step S3; NO), the central control apparatus 3, the first in the total heat exchanger 1 2 All the second fans 17 provided in the air supply pipe 11 communicating with the space 5b are turned off (step S7), and the process returns to step S1.

Next, the central control apparatus 3, the temperature difference between the indoor temperature T _{2, n} of the room temperature T _a and the n-th second space 5b of the first space 5a determines whether higher than the temperature difference B (Step S4). In this process, whether or not the indoor temperature T _{2, n} of the n-th second space 5b becomes similar temperature and the indoor temperature T _a of the first space 5a is determined. The temperature difference B at this time is set to, for example, about 0.5 ° C.

As a result of the determination, if the temperature difference between the indoor temperature _{T 2, n} of the room temperature _{T a} and the n-th second space 5b of the first space 5a is higher than the temperature difference B (Step S4; YES), the centralized control unit In step 3, the second fan 17 provided in the air supply pipe 11 communicating with the nth second space 5b is turned on (step S5). Then, the centralized control device 3 exchanges heat between the indoor air in the first space 5a and the indoor air in the nth second space 5b.

On the other hand, when the temperature difference between the indoor temperature _{T 2, n} of the room temperature _{T a} and the n-th second space 5b of the first space 5a is equal to or less than the temperature difference B (Step S4; NO), the central control apparatus 3 , The second fan 17 provided in the air supply pipe 11 communicating with the nth second space 5b is turned off (step S6), and the process returns to step S1. The process of step S4 is performed on all the second spaces 5b.

As described above, in the first embodiment, in the case of the cooling operation, when the temperature of the first space 5a in which the air conditioner 2 is installed reaches the set temperature, the heat of the indoor air in the first space 5a is reached. Is used to cool the indoor air in the second space 5b, which has a higher temperature than the first space 5a. As a result, the indoor temperature of each space can be made uniform, and the temperature barrier-free can be performed.

In this example, the temperature control during the cooling operation has been described, but the present invention is not limited to this, and the temperature control during the heating operation can also be performed. For example, during the heating operation, the central control apparatus 3, higher than the room temperature _{T a} is the set temperature _{T set} of the first space 5a, and the indoor temperature _{T 2, n} of the second space 5b indoor of the first space 5a It is lower than the temperature T _a, the second fan 17 in the air supply pipe 11 that communicates with the second space 5b turned oN. As a result, even during the heating operation, the indoor temperature of each space can be made uniform and the temperature barrier-free can be performed.

Further, the centralized traffic control device 3 starts the precooling operation of the air conditioner 2 based on the predicted operation start time (FIG. 6 (c)). The start time of the precooling operation is, for example, 30 minutes before the predicted operation start time.

At time t _1, when the room temperature T _a of the first space 5a becomes higher by A ° C. than the set temperature, the central control apparatus 3 starts the operation of the total heat exchange device 1 (Figure 6 (c)). As a result, the indoor air in the second space 5b exchanges heat with the indoor air in the first space 5a. The indoor temperature of the second space 5b is lowered, at time _{t 2, the} indoor temperature _{T 2, n} of the second space 5b reaches the set temperature _{T The set.} Here, the centralized control device 3 sets in advance a permissible temperature range for _{the room temperatures T2 and n of the second space 5b.} Then, at time t _3, when the indoor temperature T _{2, n} of the second space 5b exceeds the allowable range, the central control unit 3 stops the operation and operation of the total heat exchange device 1 of the indoor unit 22 (FIG. 6 (C)).
