Abstract
A method of and a device for controlling an air conditioning system in which an air-flow proportioning door is positioned between a heater unit and a refrigerant evaporator unit and is movable into and out of an angular position shutting off the flow of air from the evaporator unit to the heater unit and in which a refrigerant compressor unit associated with the evaporator unit is operated to alternately stop and start depending upon the temperature of the air delivered from the evaporator unit, wherein the angular position of the air-flow proportioning door and the compressor stop and start temperatures are controlled depending upon a target blowoff temperature calculated from decided and detected temperatures of the space to be air conditioned and a detected ambient temperature so as to reduce the duty cycle of the compressor unit.
