ABSTRACT:
Refrigerant flowing through each air conditioning unit of a multiple air conditioning system is respectively detected by a refrigerant flow sensor provided in each air conditioning unit and the degree of opening of a refrigerant flow control valve arranged in each air conditioning unit is controlled in response to the detection result of the corresponding refrigerant flow sensor to supply an appropriate amount of refrigerant to each air conditioning unit. The capacity of the compressor of a refrigerant supply unit of the multiple air conditioning system is controlled based on the detection result of each refrigerant flow sensor and the actual opening degree of each refrigerant flow control valve.
