PURPOSE:To prevent the discharge temperature from changing sharply and to improve the comfortableness, by shifting an A/M door in accordance with the amount of heat required for air conditioning when a compressor is turned off. CONSTITUTION:Signals of a switch 31, etc. of a control panel are inputted via a waveform shaper 34 into a microcomputer controller 37. Signals of a feedback potentiometer 33, etc. for detecting the positions of a mode door, etc., an A/M door, and sensors 32, etc. for sensing inside and outside temperatures, an insolation, blow-off temperature, evaporator discharge temperature, etc. are selected by a multiplexer 35 to be inputted into the microcomputer controller 37 via an A/D converter 36. The deviation from the predetermined temperature is get by the microcomputer controller 37 to find a required amount X of heat by PI calculation so that a compressor is controlled to be turned on or off. When the compressor is off, the amount of shift of the A/M door is controlled in accordance with said required amount X of heat so as to shift the A/M door. Thus, the discharge amount can be prevented from changing sharply. |
