Abstract
A refrigeration cycle apparatus includes a refrigerant circuit, a fan configured to send air to a heat exchanger, and a controller. The controller is configured to switch among a first operation, a second operation, and a third operation. In the first operation, the heat exchanger is caused to act as an evaporator. In the second operation, the heat exchanger is caused to act as a radiator to defrost the heat exchanger. In the third operation that is performed after the second operation, a compressor is stopped and the fan is operated at a constant rotational speed. The controller is configured to finish the third operation and start the first operation when a physical value positively correlated with electric power supplied to the fan falls to or below a threshold value during the third operation.
