Beschreibung
Zusammenfassung:	A refrigeration cycle apparatus includes: a refrigerant circuit in which refrigerant is circulated; a water circuit in which a heat medium is circulated; a water heat exchanger configured to cause heat exchange to be performed between the refrigerant and the heat medium; and a controller configured to control circulation of the refrigerant and circulation of the heat medium. The water circuit includes: a water pump configured to circulate the heat medium; an inlet-side pressure sensor provided on an inlet side of the water heat exchanger for the heat medium, and configured to detect an inlet-side water pressure that is a pressure of the heat medium which flows into the water heat exchanger; and an outlet-side pressure sensor provided on an outlet side of the water heat exchanger for the heat medium, and configured to detect an outlet-side water pressure that is a pressure of the heat medium that flows out from the water heat exchanger. The controller is configured to determine whether air enters the water circuit or not based on the inlet-side water pressure and the outlet-side water pressure.
