Claim:
A rear air conditioner installed at a rear side of a vehicle and supplying conditioned air to a rear seat area of a passenger compartment of the vehicle, the rear air conditioner comprising: a case including an inlet port through which air blown from a blower enters a vent outlet port, and a floor outlet port; a heat exchanger for cooling and a heat exchanger for heating installed in an airflow path formed inside the case; a mixing room which is formed between the two heat exchangers and the two outlet ports and in which cooled air at an outlet of the heat exchanger for cooling and heated air at an outlet of the heat exchanger for heating are mixed together to form mixed air that is to be delivered to the two outlet ports; and a single bypass passage formed inside the case to extend though said mixing room from the outlet of the heat exchanger for heating to the floor outlet port so that a part of the heated air can bypass the mixing room and be directly discharged to the floor outlet port through said bypass passage so as to re-mix said part of the heated air with the mixed air passing through the mixing room and to increase the temperature of air at the floor outlet port to be higher than the temperature of air at the vent outlet port; wherein said bypass passage is suffounded at least partially by the mixed air that is being mixed in the mixing room.
