ABSTRACT:
An apparatus for controlling the operation of an automobile air-conditioner of the type including a variable displacement compressor capable of controlling the discharge rate of a refrigerant in response to an externally supplied compressor displacement signal, wherein a total signal is calculated based on at least a vehicle compartment temperature, an outside air temperature, a solar radiation quantity, and a setting signal from a temperature setter, and when a rapid cooling is designated by the total signal, the displacement of the compressor is fixed at a maximum level for a predetermined period of time so as to preclude an undesired drop of the cooling power which would otherwise occur from the middle to the final stage of the rapid cooling operation.
