Abstract

A controller is configured to decide whether liquid refrigerant is unevenly distributed among a plurality of outdoor units and then adjust an outlet subcooling degree of an outdoor heat exchanger or an outlet sub cooling degree at a high-pressure outlet of a high-low pressure heat exchanger, and a discharge superheating degree of a compressor in a low capacity-side outdoor unit to match lower heat exchange capacity of the outdoor heat exchanger in the low capacity-side outdoor unit with higher heat exchange capacity of an outdoor heat exchanger in a high capacity-side outdoor unit, the low capacity-side outdoor unit being one of the plurality of outdoor units in which the outdoor heat exchanger has the lower heat exchange capacity, the high capacity-side outdoor unit being another of the plurality of outdoor units in which the outdoor heat exchanger has the higher heat exchange capacity.
