A heat-pump-type vehicular air-conditioning that includes a cooling refrigerant circuit. The circuit has a base for connecting an onboard condenser provided on the downstream side of an onboard evaporator inside an HVAC unit. The circuit includes a second decompression unit between the outlet side of a receiver and one end side of a vehicle-mounted external heat exchanger. Also included is a second circuit having a solenoid valve opened during heating between the other end side of the vehicle-mounted external heat exchanger and the intake circuit of an electric compressor. The vehicular air-conditioning system being provided with a heating refrigerant circuit in which the electric compressor, a switching unit, the onboard condenser, the receiver, the first circuit, the vehicle-mounted external heat exchanger, and the second circuit are connected in the stated order.
