Abstract
In a control apparatus for automobile air-conditioners including a variable displacement compressor and a fast idling device, the operation of the fast idling device is retarded until a predetermined discharge pressure of the variable displacement compressor is detected by a pressure sensor. With this retarded operation, it is possible to prevent the engine from rotating at an undue speed when the engine is operating under the fast idling mode.
