Abstract
An air-conditioning apparatus includes a refrigerant circuit, an indoor fan, a temperature sensor provided in an area adjacent to a seam in a refrigerant pipe of the refrigerant circuit, and a controller configured to determine the presence of refrigerant leakage on the basis of a decrease in the temperature measured by the temperature sensor. The controller is configured to determine the presence of refrigerant leakage while the indoor fan is stopped, and stop the determination of the presence of refrigerant leakage while a defrosting operation is performed.
