Abstract

See full text

A vehicular air conditioner includes a dehumidifying and cooling mode, in which a heating capability of a radiator can be acquired without increasing a flow rate of a refrigerant into a heat absorber. The dehumidifying and cooling mode lets the refrigerant discharged from a compressor (2) radiate heat in a radiator (4) and an outdoor heat exchanger (7), decompress the refrigerant by which heat has been radiated, and then let the refrigerant absorb heat in a heat absorber (9). The vehicular air conditioner includes an injection circuit (40) which distributes a part of the refrigerant flowing out from the radiator (4) to return the part of the refrigerant to the compressor (2). In the dehumidifying and cooling mode, the injection circuit (40) is operated to return the refrigerant to the compressor (2) when there is a predetermined radiator capability shortage condition and/or predetermined low outdoor air temperature startup condition.
