Claim:
1. An air conditioner for a vehicle comprising: an air blowing device; an air-conditioning case having an air inflow port formed on one side for introducing the air blown from the air blowing device into the air-conditioning case, a plurality of air outflow ports formed on the other side for discharging out air, a cold air passageway which is formed between the air inflow port and the air outflow ports and in which an evaporator is mounted, and a warm air passageway in which a heater is mounted; a desiccant rotor mounted at the upstream side of the evaporator in an air flow direction inside the air-conditioning case, one side of the desiccant rotor relative to the air-conditioning case being used as a desiccant part for dehumidifying the air flowing inside the air-conditioning case, the other side of the desiccant rotor being used as a regeneration part for drying and regenerating moisture absorbed at the desiccant part; a bypass passageway and a regeneration passageway formed below the cold air passageway and the warm air passageway inside the air-conditioning case, the bypass passageway being adapted to let some of the air passing through the desiccant part of the desiccant rotor bypass the cold air passageway and the warm air passageway, the regeneration passageway being adapted to supply the air passing through the bypass passageway to the regeneration part of the desiccant rotor; a communication chamber formed at an outlet of the bypass passageway inside the air-conditioning case for communicating the rear side warm air passageway of the heater, the bypass passageway and the regeneration passageway with one another, and a door mounted inside the communication chamber for selectively opening and closing the rear side warm air passageway of the heater, the bypass passageway and the regeneration passageway relative to the communication chamber, wherein the heater has one side area arranged on the bypass passageway and the other side area arranged on the warm air passageway in order to heat the air flowing the bypass passageway and the warm air passageway, and heats the dehumidified air passing the bypass passageway through the desiccant part of the desiccant rotor, and then, supplies the heated air to the regeneration part of the desiccant rotor so as to regenerate the desiccant rotor.
