Abstract

See full text

There is disclosed a vehicle air conditioner which can realize a desirable outlet temperature even when a refrigerant subcool degree of a radiator varies. A controller executes a heating mode to let a refrigerant discharged from a compressor 2 radiate heat in a radiator 4, decompress the refrigerant by which heat has been radiated, and then let the refrigerant absorb heat in an outdoor heat exchanger 7, thereby heating the vehicle interior. The controller controls the compressor 2 on the basis of a radiator target pressure, and corrects the radiator target pressure in such a direction as to heighten when a target subcool degree enlarges, on the basis of the target subcool degree (the refrigerant subcool degree) of the radiator 4.
