冷房作用を行う。In the apparatus configured as described above, FIG. 3 shows that when the maximum cooling capacity is required during the cooling operation, that is, the air blown out from the vehicle interior outlet 13 to air-condition the vehicle interior is It shows a configuration in which heat exchange is performed only in the first vehicle interior air heat exchanger 3, and heat exchange in the second vehicle interior air heat exchanger 4 is not required. The flow of the refrigerant is indicated by arrows, and the first damper 14 and the second damper 15 are in the positions shown by solid lines so that heat does not enter and leak. Therefore, the high-temperature and high-pressure refrigerant discharged from the compressor 1 is not heat-exchanged in the second vehicle interior air heat exchanger 4, but is radiated by the vehicle exterior air heat exchanger 2 to condense and liquefy the refrigerant. . And
The pressure is reduced by the refrigerant expansion device 5, and is guided to the first vehicle interior air heat exchanger 3. Further, by exchanging heat with the air blown by the air blower 10 for the vehicle interior air heat exchanger, the refrigerant evaporates while cooling and dehumidifying and returns to the compressor 1 to perform a cooling operation.

力が引き出せなくなる。However, in the above structure, the second damper 15 located behind the second vehicle interior air heat exchanger 4 is installed in the ventilation circuit 12 in the limited space of the vehicle. Moreover, it is very difficult to make it variable. Further, as shown in FIG. 4, it is assumed that only the first damper 14 in front of the second vehicle interior air heat exchanger 4 is used. In this case, the air cooled and dehumidified by the first vehicle interior air heat exchanger 3 does not pass through the second vehicle interior air heat exchanger 4 by the first damper 14. However, since the high-temperature refrigerant always flows through the second vehicle interior air heat exchanger 4, heat leaks from the leeward side and the temperature of the cooled air rises, so that the maximum cooling capacity cannot be drawn out. .
