ABSTRACT:
Defrosting operation is possible by causing refrigerant discharged from a compressor to flow to an outdoor heat exchanger, and returning the refrigerant passed through the outdoor heat exchanger to the compressor through a water-heat exchanger, while operating a pump. Quick defrosting operation is possible by causing refrigerant discharged from a compressor to flow to an outdoor heat exchanger, and returning the refrigerant passed through the outdoor heat exchanger directly to the compressor, while stopping a pump. The temperature of water that has flowed into a water-heat exchanger is detected. According to the detected temperature, the defrosting operation using hot water and quick defrosting operation are selectively executed.
