ABSTRACT:
A vehicle air conditioner selectively switches one of a cooling mode in which an interior heat exchanger of a refrigerant cycle is operated as an evaporator for cooling air, and a heating mode in which the interior heat exchanger is operated as a radiator for heating air. In the vehicle air conditioner, an accumulator, for separating gas refrigerant and liquid refrigerant from each other and for storing the separated liquid refrigerant therein, is disposed between an outlet of the interior heat exchanger and a suction port of a compressor. Further, the accumulator includes a heating device for heating the liquid refrigerant stored in the accumulator in the heating mode. Therefore, heating performance for heating air in heating mode can be efficiently improved.
