Abstract: An outdoor unit control unit includes a degree-of-dryness calculating unit that calculates the degree of dryness of a refrigerant flowing into an heat exchanger (an indoor heat exchanger at the time of a cooling operation, and an outdoor heat exchanger at the time of a heating operation) disposed on the downstream side of a liquid pipe, and performs an inhibition mode of inhibiting, when the degree of dryness exceeds a threshold A, control that is performed in the direction of decreasing the degree of opening of the expansion valve (an indoor expansion valve at the time of the cooling operation, and an outdoor expansion valve at the time of the heating operation) disposed on the upstream side of the liquid pipe.
