AIR CONDITIONING DEVICE FOR VEHICLE

WIPO Patent Application WO/2012/108240

A1

Provided is an air conditioning device for a vehicle, configured so that frost does not form on the heat absorber even in an environment in which the temperature outside the vehicle interior is low. In a dehumidifying heating operation, when the temperature (Tam) outside a vehicle interior is lower than or equal to a predetermined temperature (T1) or when the temperature (Thex) of a refrigerant flowing out from an outdoor heat exchanger (22) is lower than or equal to a predetermined temperature (T2), if the temperature (Te) detected by a cooling air temperature sensor (44) is lower than or equal to a temperature (Tet-β), a third solenoid valve (25c) is closed. As a result, the flow of the refrigerant to the heat absorber (14) is stopped when frost is likely to form on the heat absorber (14) during the dehumidifying heating operation, and therefore frosting on the heat absorber (14) is prevented.
