Abstract
A refrigeration cycle apparatus includes a compressor, first and second heat exchangers, an expansion valve, a four-way valve, and a controller. The four-way valve is configured to switch a direction of flow of the refrigerant between a first direction and a second direction. The controller is configured to control the four-way valve to switch an operation from a defrosting operation in which the refrigerant flows in the second direction, to a heating operation in which the refrigerant flows in the first direction, to perform a heating preparation control for increasing a degree of superheat of the refrigerant output to the compressor from the second heat exchanger, and thereafter to start the heating operation.
