In a dehumidification-air heating mode, a refrigerant circuit is configured such that a refrigerant outlet side of an exterior heat exchanger communicates with a heating side refrigerant suction port of a heating side ejector as a refrigerant decompression means, and that a refrigerant inlet side of an interior evaporator communicates with an outlet side of a heating side diffuser of the heating side ejector. A refrigerant evaporation temperature in the exterior heat exchanger is set lower than that of the interior evaporator by a pressurizing effect of the heating side ejector. Thus, the amount of heat absorption by the refrigerant at the exterior heat exchanger is increased to improve the heating capacity of the air in an interior condenser.
