Abstract
A vehicle air conditioner is controlled so a target control value of a pressure control valve controlling tilt angle of a swash-plate of a swash-plate type variable capacity compressor is variably controlled according to temperature deviation between target evaporator temperature and actual evaporator temperature, thereby controlling the compressor discharge capacity. Target heat discharge quantity is calculated. Target heat discharge quantity is calculated for high thermal load control or low thermal load control. The control value of the pressure control valve is compulsively controlled. Then the control value is normally controlled. The actual evaporator temperature can reach the target evaporator temperature at an initial operating stage, and temperature stability is secured.
