PROBLEM TO BE SOLVED: To solve the problem of increasing a refrigerant leakage amount in case of refrigerant leakage due to an accident when using a combustible refrigerant to cause an excess refrigerant to be needed in a sealed refrigerant necessary for operating a refrigerating operation from the result of staying the refrigerant without flowing of a liquid phase refrigerant by different flowing speeds of vapor phase and the liquid phase refrigerants and vertical flow of the refrigerant according to a flowing state or flowing speed in two phase of vapor and liquid phase flows of the refrigerant in tubes in the case of moving the refrigerant during upward piping of a condenser. SOLUTION: The refrigerator comprises a refrigerating cycle having a body 20, a compressor 21 installed in the body 20, a condenser 22, a capillary tube 23, and an evaporator 24 sequentially annularly connected, and a combustible refrigerant 25 such as a butane, an isobutene, a propane or the like sealed in the cycle. In this case, refrigerant piping 26 for constituting the condenser 22 is disposed on a horizontal surface.
