Abstract

The present disclosure provides a refrigeration cycle apparatus that can restrain the internal temperature of a compressor from excessively rising at the start of the compressor. The refrigeration cycle apparatus in the present disclosure includes: a first bypass refrigerant circuit providing communication between a main refrigerant circuit on a downstream side of a compressor and the main refrigerant circuit on an upstream side of the compressor; a first bypass valve provided in the first bypass refrigerant circuit, the first bypass valve being configured to open and close the first bypass refrigerant circuit; a water temperature sensor configured to detect a temperature of water flowing into a use side heat exchanger from a water pipe; and a controller configured to recognize an operating state of the compressor based on the temperature detected by the water temperature sensor at start of the compressor and bring the first bypass refrigerant circuit into an open state using the first bypass valve when recognizing that the compressor is in a predetermined insufficient refrigerant discharge state.
