Abstract
A rear air conditioner is installed at a rear side of a vehicle and supplies conditioned air to a rear seat area of a passenger compartment of the vehicle. The rear air conditioner includes a case, a heat exchanger for cooling, a heat exchanger for heating, and a bypass passage for guiding part of warm air. The case includes an inlet port through which air blown from a blower enters, a vent outlet port, and a floor outlet port. The heat exchanger for cooling and the heat exchanger for heating are installed in an airflow path formed inside the case. The bypass passage extends from an outlet of the heat exchanger for heating to the floor outlet port so that warm air passing through the heat exchanger for heating can be directly discharged to the floor outlet port. Accordingly, the rear air conditioner can offer improved performance to control a vertical difference of temperature in a cold and warm air mixing mode.
