As shown in the refrigeration cycle diagram of FIG. 3, a compressor 1, a four-way valve 2, an indoor heat exchanger 3, a decompressor 4, and an outdoor heat exchanger 5 are sequentially connected to form a refrigerant circuit. As indicated by the dotted arrow, the high-temperature gas on the discharge side of the compressor 1 is switched by the four-way valve 2 to flow into the outdoor heat exchanger 5 for defrosting. However, during this defrosting operation, the cold refrigerant condensed in the outdoor heat exchanger 5 and blown out from the decompressor 4 flows into the indoor heat exchanger 3, and the indoor heat exchanger 3 is cooled. At the end of the heating operation, cold air is blown out, which causes a problem of giving the user discomfort. Conventionally, in order to prevent the indoor heat exchanger 3 from being cooled during the defrosting operation, as shown in the refrigeration cycle diagram of FIG. A bypass pipe 6 is connected to the bypass pipe 6, and an electromagnetic on-off valve 7 is interposed in the bypass pipe 6, and the four-way valve is switched to a heating operation when the outdoor heat exchanger 5 is frosted as shown by an arrow. Without opening the electromagnetic on-off valve 7, the high-temperature gas from the compressor 1 bypasses the indoor heat exchanger 3 and flows into the outdoor heat exchanger 5 for defrosting as shown by the dotted arrow. A refrigerant circuit has been considered. However, in this refrigerant circuit, at the time of defrosting, a refrigerant circuit circulated to the compressor 1 through the compressor 1, the bypass pipe 6, the outdoor heat exchanger 5 and the four-way valve 2 is formed. Since the resistance of the compressor 1 is not included, the load on the compressor 1 is reduced. On the other hand, once the refrigerant gas is not compressed and heat is released, the refrigerant does not become hot and dehumidification occurs. There is a problem that the efficiency is reduced. In addition, when the electromagnetic on-off valve 7 is closed to end the defrosting operation, the load on the compressor 1 increases sharply, and a sudden load is applied to the compressor 1 to shorten the life of the compressor 1. there were.
