SOLUTION: Outside units 11A, 11B respectively having compressors 16A, 16B, and inside units 12A, 12B respectively having an electric expansion valves 28A, 28B and inside heat exchangers 27A, 27B are connected with each other by piping 42 between units. The number of operating outside units 11A, 11B is controlled according to an inside air conditioning load. In this air conditioner, a control device 13 is provided, which limits the opening of the electric expansion valves 28A, 28B of the inside units 12A, 12B to specified values when the number of the operating outside units is changed at cooling operation.
