摘要:
According to the present invention, when leakage of refrigerant is detected during operation of an air conditioning apparatus for a vehicle, air outlets for a passenger and a solenoid valve for an air passage are closed. Accordingly, a compressor is stopped after a predetermined time has elapsed since the solenoid valve is closed. In this way, refrigerant within an evaporator is sucked and discharged. Consequently, an amount of refrigerant leaking from an air conditioner casing due to damage of the evaporator can be reduced.
