Abstract
A refrigeration cycle apparatus includes a refrigerant circuit, a water circuit, a water heat exchanger, and a controller. The water circuit includes: a water pump; an inlet-side pressure sensor 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 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.
