    摘要： A multi-system air conditioner comprises an exterior unit including a compressor and a plurality of interior units, each being installed in a room and including a heat exchanger and an expansion valve therefor. An opening degree of the expansion valve in an interior unit is controlled based on not only the superheat degree of the compressor but also the room temperature difference. Further, the control based on the superheat degree is carried out by means of the fuzzy logical calculation on superheat degree value. A rotational speed of the compressor is controlled based on not only the load capacity of the room but also the room temperature difference. Further, a control based on the fuzzy logical calculation on the pressure value is added. A feed forward control is also added so as to shorten the transient time.
