Abstract:
An air conditioner for a vehicle having a passenger compartment, said air conditioner comprising:a duct for forming an air passage through which air flows;a blower for blowing air in said air duct into the passenger compartment;an evaporator, disposed in said duct, for cooling air flowing through said air passage by evaporating refrigerant flowing therein;a condenser for heating air passing there through by condensing refrigerant flowing therein, said condenser being disposed in said duct at a downstream air side of said evaporator to form a bypass passage through which air having passed through said evaporator bypasses said condenser;an air mixing door for adjusting a ratio between an amount of air passing through said condenser and an amount of air passing through said bypass passage;a compressor for compressing and discharging refrigerant;a decompressing unit for decompressing and expanding refrigerant;an outside heat exchanger disposed outside said duct, for performing heat-exchange between refrigerant flowing therein and outside air outside the passenger compartment; anda control unit for controlling a flow direction of refrigerant and operation of said air mixing door, in such a manner that refrigerant flows in the order of said compressor, said outside heat exchanger, said decompressing unit, said evaporator and said compressor, and said air mixing door substantially fully opens said bypass passage and closes said condenser so that air bypasses said condenser, during cooling operation for cooling the passenger compartment.
