A compressor 1, a first channel switching valve 2, an outdoor side heat exchanger 3, an expansion valve 4, an indoor side heat exchanger 5 and a second channel switching valve 6 are sequentially connected to form a refrigerant circuit. A refrigerant channel of the exchanger 3 is formed of two passes of a first channel 3a and a second channel 3b. The channel 3a and the channel 3b are connected in series through a first opening/closing valve 1. A second opening/closing valve 8 is connected between a connecting point of the valve 7 to the channel 3b and the valve 6, and a third opening/closing valve 9 is connected between the valve 2 and the valve 6.
