AIR CONDITIONER FOR VEHICLE

摘要

PURPOSE: An air conditioner for a vehicle is provided to utilize a heating device by dividing the same into two parts without a separate heat source when reproducing a humidifying rotor, thereby reducing the number of parts and the entire size. CONSTITUTION: An air conditioner for a vehicle comprises a blower and an air conditioning case(110). A dehumidifying rotor(120) is installed in the upstream of an evaporator(101) in a direction where air flows inside the air conditioning case. One side of the dehumidifying rotor is utilized as a dehumidifying unit(121) dehumidifying the air flowing inside the air conditioning case. The other side of the dehumidifying rotor is utilized as a reproducing unit(122) which dries and reproduces the moisture adsorbed by the dehumidifying unit. A heater(102) heats the air flowing inside a bypass passage(130) and a cold air passage(P1). The air has passed through the bypass passage after passing through a reproducing passage which is supplied to the reproducing unit of the dehumidifying rotor.
