Abstract
A refrigeration cycle apparatus is provided with a compressor, a condenser, a pressure-reducing device, and an evaporator. The refrigeration cycle apparatus comprises a refrigeration cycle configured to circulate refrigerant; and a control unit configured to control the refrigeration cycle. The control unit causes the refrigeration cycle to operate when an operation condition is satisfied, the operation condition including elapse of a preset time after the control unit stops the refrigeration cycle. The control unit detects abnormality of the refrigeration cycle based on state data indicating a state of the refrigeration cycle after the control unit causes the refrigeration cycle to operate.
