PROBLEM TO BE SOLVED: To raise the cooling capacity and also, raise the work efficiency at setup, by arranging a part of a capillary tube close to a cooler. SOLUTION: One end of a capillary tube 42 is connected through a coupling 40 to the refrigerant pipe 38 led out of the refrigerant outlet of a condenser 22. The capillary tube 42 is led in a storage room 14 through the through hole in a bulkhead 16 from a machine room 18 and is arranged properly within the storage room 14, and then its other end is connected to the refrigerant inlet of a cooler 28. A difference part 42a covering the specified length of the capillary tube 42 is arranged in bellow shape close to the cooler 28, between the air suction side of the fan 36 within a storehouse and the cooler 28. Hereby, the liquefied refrigerant circulating within the capillary tube 42 exchangers its heat with the cooler 28, and the liquefied refrigerant is supercooled.
