A VARIABLE VOLUME COMPRESSURE CONTROL METHOD FOR A VEHICLE'S AIR CONDITIONER

摘要

PURPOSE: A variable capacity type compressor control method for a vehicle air-conditioning device is provided to increase the capacity of a variable capacity type compressor using table map which is proportional to difference between evaporator freezing temperature and evaporator pass temperature. CONSTITUTION: A vehicle air-conditioning device comprises an indoor air conditioning unit with a refrigerant cooling system and an evaporator, an evaporator temperature sensor which feeds back the discharge temperature of the evaporator, an remote-controllable variable capacity type compressor capable of electrically controlling variable capacity, and a controller which can control all actuators of the indoor air conditioning unit and the remote-controllable variable capacity type compressor. The capacity of the variable capacity type compressor is increased by a table map which is proportional to difference between evaporator freezing temperature and evaporator pass temperature using fuel injection amount, vehicle speed, and brake signals.
