Original Abstract Submitted
A refrigerant leak determination apparatus is provided with a refrigeration cycle device, connection devices, and a control device. The refrigeration cycle device is configured with an indoor unit and an outdoor unit. The refrigeration cycle device includes a refrigerant circuit. Each of the connection devices has a communication opening to an internal space of the refrigerant circuit, and is connected to a pressure sensor that measures a refrigerant pressure in the internal space. The control device causes the refrigeration cycle device to perform oil recovery operation to collect oil inside the refrigerant circuit in a compressor, and determines a leak of the refrigerant from the refrigerant circuit, by comparing a reference pressure with the refrigerant pressure measured by the pressure sensor after the oil recovery operation.
