WIPO Patent Application WO/2023/002520
Kind Code:
A1
Abstract:
Provided is a refrigeration cycle device having a refrigerant circuit in which a compressor, a condenser, a pressure-reducing device, and an evaporator are connected via piping, and a refrigerant circulates through the piping. The refrigeration cycle device comprises: a refrigerant leak detector that detects a refrigerant leak from the refrigerant circuit and transmits a detection signal; and a control device. The control device performs, on the basis of the detection signal from the refrigerant leak detector, detection of a refrigerant leak from the refrigerant circuit, and performs, on the basis of the state of the refrigerant or a device of the refrigerant circuit, a refrigerant leak determination process for the refrigerant so as to perform detection of a refrigerant leak.
