REFRIGERATION CYCLE APPARATUS

摘要

Refrigeration cycle equipment includes a compressor 6, an indoor heat exchanger 16, an expansion valve 12, and an outdoor heat exchanger 14, all connected to one another via refrigerant piping. The refrigeration cycle equipment also includes a heat storage device having a heat storage material 36 disposed around the compressor 6 to store heat generated by the compressor 6 and a heat storage heat exchanger 34 for heat exchanging between heat stored in the heat storage material 36 and a refrigerant. In a defrosting operation, a refrigerant discharged from the compressor 6 is partly introduced to the outdoor heat exchanger 14 via a pipe 28, and a refrigerant discharged from the indoor heat exchanger 16 is introduced to the heat storage heat exchanger 34 via a pipe 38. Also, a refrigerant discharged from the heat storage heat exchanger 34 joins a refrigerant discharged from the outdoor heat exchanger 14.
