PROBLEM TO BE SOLVED: To reduce the emergence of such a situation that power supply to a refrigerator is cut off to make it impossible to detect refrigerant leakage.SOLUTION: In a refrigerant circuit 11, inflammable refrigerant is circulated. A compressor 21 receives power supply from the outside for circulating the refrigerant in the refrigerant circuit 11. A refrigerant gas sensor 31 and an outdoor side control device 37, and a refrigerant gas sensor 45 and an indoor side control device 47 receive power supply from the outside for detecting refrigerant leakage from the refrigerant circuit 11. A liquid crystal display device of a remote controller 48 visibly displays transmission information that it is impossible to detect the refrigerant leakage when power supply is stopped.SELECTED DRAWING: Figure 1 |
