Abstract
A method for controlling the operation of a variable displacement refrigerant compressor arranged in a car air-conditioner circuit and driven by a car engine via a solenoid clutch is carried out in a manner such that, when either an air-conditioner OFF signal or an ignition OFF signal is received by a control device having a CPU unit therein prior to a start of a long time stoppage of the car, a displacement varying wobble plate element is always moved angularly to a predetermined position to obtain a minimum displacement condition of the compressor so that the compressor is restarted from the minimum displacement condition when the car is restarted after a long time stoppage thereof.
