This vehicle air-conditioning device is provided with a hot-water heater core, a heat pump, an electric heater, and a control device. The hot-water heater core is provided in a hot-water circuit that causes a coolant to circulate to a heat source so as to collect waste heat from the heat source. The hot-water heater core heats air by exchanging heat between the coolant heated by the waste heat from the heat source and the air and uses the heated air to heat the vehicle interior. The heat pump heats air by causing an indoor heat exchanger to exchange heat between a refrigerant discharged from a refrigerant compressor and the air and uses the heated air to heat the vehicle interior. The electric heater heats the vehicle interior by heating air. The control device performs heating by selecting some or all of the hot-water heater core, the heat pump, and the electric heater. |
