PROBLEM TO BE SOLVED: To prevent a lubricant oil returning to a plurality of parallel connected compressors from becoming non-uniform even in the case where the compressors are connected. SOLUTION: An outdoor device 20 (20a, 20b) is formed by a compressor 21 (21a, 21b) compressing refrigerant and an outdoor heat exchanger 22 (22a, 22b) for heat exchanging the refrigerant with outdoor air. A plurality of outdoor devices 20 are connected by a branch device 30. The branch device 30 is provided with a plurality of flow rate adjuster 32 (32a, 32b), thereby adjusting an amount of refrigerant flowing into or discharging out of each of the outdoor devices 20 in compliance with a capability of each of the compressors 21.
