A vehicle air conditioner includes a refrigeration cycle unit, a heater core, a cool air bypass passage, an air volume ratio regulator, and an auxiliary heat exchanger. The heater core is disposed in a heating passage located downstream of an evaporator with respect to an airflow. The auxiliary heat exchanger is provided in the refrigeration cycle unit. The evaporator includes a cold energy storage. The cold energy storage stores cold energy when the compressor is in operation, and dissipate cold energy while the compressor stops. The auxiliary heat exchanger is located downstream of the evaporator and upstream of the heater core with respect to the airflow. The auxiliary heat exchanger changes enthalpy of refrigerant by heat exchange between the refrigerant and air having been cooled by the evaporator and to be heated by the heater core.
