作用を行うものであった。2. Description of the Related Art A conventional air conditioner for a fuel-driven vehicle, for example, as shown in FIG. 4, has a cooling function in which a compressor 1 for compressing a refrigerant is driven by an engine and outdoor heat exchange is performed. The refrigerant is condensed and liquefied by radiating heat to the vehicle exterior air by the heat exchanger 2 and the outdoor heat exchanger blower 3, and then the refrigerant is guided to the indoor heat exchanger 5 through the refrigerant expansion device 4, and the indoor blower 6 Thus, the air blown by the evaporator is evaporated while cooling, thereby performing a cooling operation.

連続して変化させることが可能である。The temperature of the air blown from the air outlets 10, 11, and 12 in the vehicle compartment is adjusted by adjusting the opening of a mix damper 16 disposed in a ventilation duct 20.
This is performed by adjusting the amount of warm air flowing through the heater core and the amount of cool air that bypasses the heater core 15. Further, the compressor 1 is driven by the engine, and the air cooled by the indoor heat exchanger 5 is reheated by the heater core 15 to perform dehumidifying heating. Further, by using the mix damper 16, it is possible to continuously change the blowing temperature from cooling to heating and vice versa.

Shown in The cooling operation is the same as above, but the cooling water (warm water) of the engine is not provided for the heating device. Therefore, the refrigerant flow path is reversed by using the four-way switching valve 7 downstream of the compressor 1, and the indoor heat exchanger After the air blown by the indoor blower 6 is heated at 5 to condense and liquefy the refrigerant, the refrigerant is guided to the outdoor heat exchanger 2 via the refrigerant expansion device 4, where the air outside the vehicle is cooled. While the refrigerant absorbs heat and evaporates, heat pump heating is performed. Therefore, since there is no mix damper as in the air conditioner for a fuel-driven vehicle, the blowout temperature is adjusted by controlling the motor driving device 9 that drives the electric motor 8 to adjust the rotation speed of the compressor 1. Become. Switching between heating and cooling is performed by a four-way switching valve 7.
Is used to switch the refrigerant flow path.

曇ることとなり走行安全上不都合となる。In a heat pump heating system in which the refrigerant absorbs heat and evaporates while cooling the air outside the vehicle compartment using an outdoor heat exchanger, the boiling point of the refrigerant approaches as the vehicle exterior temperature decreases. The efficiency is reduced, and the power consumption of the motor driving the compressor is increased. In the case of an electric drive vehicle, if the power consumption of the air conditioner increases, the power consumption of the motor for driving the vehicle is reduced, which affects the driving performance. Therefore, if the heating is performed by circulating the air in the vehicle compartment instead of introducing and heating the air outside the vehicle compartment, the heat load is small and the power consumption of the motor driving the compressor is reduced. However, when circulating vehicle interior air,
Since the vehicle interior humidity rises and the vehicle exterior temperature is low, the window glass becomes cloudy, which is inconvenient for traveling safety.
