A refrigerant/heat medium heat exchanger that heats a heat medium which circulates in a heater core of an HVAC unit is provided in a discharge pipe of a cooling refrigerant circuit, a heating bypass circuit that extends to a receiver is connected to a downstream side of the refrigerant/heat medium heat exchanger through a switching means, a second circuit having a second decompression means is provided between an outlet of the receiver and a first end of a vehicle exterior heat exchanger, and a third circuit having a solenoid valve is provided between a second end of the vehicle exterior heat exchanger and an intake circuit. In a vehicle air-conditioning system, a heating refrigerant circuit is configured by an electric compressor, a refrigerant/heat medium heat exchanger, a switching means, a heating bypass circuit, a receiver, a second circuit, a vehicle exterior heat exchanger, and a third circuit. Consequently, while simplification of a configuration and the like are attained by diverting cooling refrigerant circuit and an HVAC of a current system, cooling/heating capacity can be ensured by diversifying heating heat sources, and operation in a frost formation delay mode or the like is possible during heating.
