Zusammenfassung:	Refrigerant flowing through each air conditioning unit (C1..Cn) of a multiple unit air conditioning system is respectively detected by a refrigerant flow sensor 45 in each unit and the degree of opening of a respective refrigerant flow control valve 49 is controlled so as to bring the refrigerant flow to a target value determined, for example, in response to detected room temperature. The capacity of the compressor 23 of a refrigerant supply unit A of the system is controlled according to the total of the respective target values of refrigerant flow. In a second embodiment (Fig 9) a distribution unit (B), remote from a group of air conditioning units (C1-C3) communicates therewith via a wireless remote controller (65a). The system may be used in respective rooms of a building or (second embodiment) in respective areas of a room wherein the capacity of each unit is small.
