More Information
Summary:A vehicle air conditioner includes an air-heating switching portion that switches between a first air-heating mode of heating ventilation air by a heating heat exchanger and a second air-heating mode of heating the ventilation air by a condenser. The vehicle air conditioner includes a heat-exchange adjustment portion that adjusts an amount of heat exchange between the high-pressure refrigerant and the ventilation air in the condenser, and a heat-exchange control unit that controls the heat-exchange adjustment portion. The heat-exchange control unit controls the heat-exchange adjustment portion to decrease the amount of heat exchange between the high-pressure refrigerant and the ventilation air in the condenser if a condition satisfies in which temperature of the refrigerant in the condenser is equal to or lower than temperature of the ventilation air heated by a heating heat exchanger before passing through the condenser, when the air-heating switching portion switches from the first air-heating mode to the second air-heating mode.
