段１８を設けたことを特徴とする空気調和装置。 It is equipped with a compressor 1, a four-way switching valve 2, an indoor heat exchanger 3, a pressure reducing mechanism 4, and an outdoor heat exchanger 5, and by switching the four-way switching valve 2, heating operation is performed as a heating cycle, In an air conditioner that performs a defrosting operation as a cooling cycle when the outdoor heat exchanger 5 is frosted, the refrigerant absorber 9 is installed in the refrigerant pipe 8 that becomes a low-pressure gas pipe in the cooling cycle and becomes a high-pressure gas pipe in the heating cycle. Refrigerant piping 8
A connecting pipe 11 is connected to the refrigerant absorber 9 and a refrigerant pipe 10, which becomes a high-pressure liquid pipe in the cooling cycle, with a solenoid valve 12 interposed therebetween. , the solenoid valve 1
2, outputs an open operation command for a predetermined time before the switching operation of the four-way switching valve 2 due to the return of heating operation by the heating cycle in the latter half of the defrosting operation, and also outputs an open operation command for a predetermined time after this switching operation. An air conditioner characterized in that a valve control means 18 is provided.
