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 a car engine rotating speed is lower than an idling speed and when either one of a brake pedal or a manual brake of the car is released after temporary stoppage of the car, a control device having a CPU unit therein issues a control signal to cause a displacement varying wobble plate element of the variable displacement refrigerant compressor to be 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 temporary stoppage thereof at, e.g., an intersection of a vehicle road.
