Abstract
A vehicle air-conditioning system includes an HVAC unit that blows air whose temperature is adjusted by a refrigerant evaporator and a second refrigerant condenser. The system includes a heat pump cycle in which a refrigerant compressor, a refrigerant circuit changeover section, a first refrigerant condenser, a first expansion valve, and the refrigerant evaporator are sequentially connected. The system includes a second expansion valve and a refrigerant heat exchanger connected in parallel with the first expansion valve and the refrigerant evaporator. The second refrigerant condenser is connected in parallel with the first refrigerant condenser. The system includes a coolant cycle in which a coolant circulating pump, a ventilation-exhaust-heat recovery unit, a motor/battery, an electric heater, and the refrigerant heat exchanger are sequentially connected, and the ventilation-exhaust-heat recovery unit, motor/battery, and electric heater can be selectively used as a heat source.
