Abstract
This vehicle air conditioner includes: a component temperature-adjustment path in which a coolant flows for performing a heat exchange with a vehicle component which needs a temperature adjustment; an engine coolant path in which an engine coolant guided from an engine cooling portion flows; a heater core. The vehicle air conditioner further includes: a first water-refrigerant heat exchanger which performs a heat exchange between a low-temperature and low-pressure refrigerant of a heat pump, the coolant fed to the component temperature-adjustment path, and the engine coolant; a second water-refrigerant heat exchanger which performs a heat exchange between a high-temperature and high-pressure refrigerant of the heat pump, and the engine coolant; and a first switch which can switch between a state where the engine coolant flows to the first water-refrigerant heat exchanger and a state where the refrigerant bypasses the first water-refrigerant heat exchanger.
