Abstract
In an apparatus for controlling a variable displacement compressor incorporated in an automobile air-conditioner, the displacement of the compressor is varied with a change in the target cooling temperature. The change rate of the target cooling temperature thus changed is limited to such an extent that a sudden change in displacement of the compressor is prevented to maintain the drivability of an automobile and to change the cooling power of the evaporator gently, thereby keeping a pleasant feeling during the temperature regulating operation. The change rate of the target cooling temperature can be selected from a plurality of predetermined values to meet a current controlling condition so that the reliability of the air-conditioner is improved.
