Abstract:
An automotive air conditioner, comprising:a duct defining a passageway for conditioned air to a room of an automobile;a blower for blowing air toward the room of the automobile by way of said duct;an evaporator disposed in said duct for evaporating refrigerant to cool air;a heater disposed on the downstream side of said evaporator in said duct for causing refrigerant of a high temperature and air to exchange heat with each other to heat the air;a compressor for compressing and discharging refrigerant;an outside heat exchanger disposed outside said duct for causing air outside said duct and refrigerant to exchange heat with each other;an accumulator disposed at an upstream refrigerant side of said compressor, for accumulating liquefied refrigerant therein and for leading gaseous refrigerant into said compressor; andexpanding means for decompressing and expanding refrigerant, said expanding means including an electric expansion valve which varies the throttling amount of a flow of refrigerant in response to an electric signal so that a sub-cool amount of refrigerant passing through said expanding means is varied in accordance with an air-conditioning load of the automotive air conditioner.
