ABSTRACT:
An automobile air-conditioner of the type having a variable displacement compressor, wherein a desired degree to which an evaporator is cooled is calculated by a desired cooling degree calculation means, and a desired rotational speed of a blower is calculated by a desired rotational speed calculation means. The results of calculation by both of the calculation means are used for controlling the displacement of the variable displacement compressor. Thus, the displacement of the compressor is corrected in immediate response to a change of thermal loads.
