Abstract
A refrigeration cycle apparatus includes an indoor heat exchanger, a water heat exchanger, a pump, an outdoor heat exchanger, a compressor, an expansion valve, a four-way valve, a third pipe, and an open/close valve, and configured to enable hot-gas defrosting and reverse cycle defrosting. A controller selects, based on the indoor load, either one of the hot-gas defrosting and the reverse cycle defrosting to be performed. In this way, defrosting can be performed with a minimum decrease of the chiller water temperature.
