A control device (27) determines whether a refrigerant has been unevenly distributed among a plurality of outdoor units (10), and, if the refrigerant is determined to be unevenly distributed among the plurality of outdoor units (10), adjusts the degree of supercooling at an outlet of an outdoor heat exchanger (5) or the degree of supercooling at an outlet on the high pressure side outlet of a high-and-low pressure heat exchanger (6) and adjusts the degree of superheating discharge from a compressor (1) so that the heat capacity rate of the outdoor heat exchanger (5) for the high capacity side outdoor unit (10), with a high heat capacity rate for the outdoor heat exchanger (5), and the heat capacity rate of the outdoor heat exchanger (5) for the low capacity side outdoor unit (10), with a low heat capacity rate for the outdoor heat exchanger (5), are matched to the higher of the heat capacity rates. |
