PURPOSE: A refrigerator is provided to remove liquid refrigerant remaining in gas refrigerant flowing to a compressor from an evaporator effectively without depending on the brazing structure. CONSTITUTION: A compressor connecting pipe(52) includes: a first contact unit(5) having nuts at both ends(5a,5b); a second contact unit(57) arranged perpendicular to the first contact unit, having an opening end(57a); and a connecting portion(6) mounted between the first and the second contact unit, having a path for connecting the second contact unit with the second end(5b) of the first contact unit. An evaporator connecting pipe(53) has the same structure as the compressor connecting pipe. A capillary tube(4) is inserted into the opening end of the compressor connecting pipe to reach a second end(5b) of the evaporator connecting pipe via a refrigerant tube(9). Then, the capillary tube is connected to an evaporator inlet pipe via an opening end(57a). The opening end has a packing(8) for preventing leakage of refrigerant flowing through the two connecting pipes. High-temperature high-pressure gas refrigerant of a compressor is liquefied in a condenser and supplied to an evaporator through the capillary tube. The gas refrigerant is heat-exchanged in a storage unit and flowed through the evaporator connecting pipe, the refrigerant tube and the compressor connecting pipe sequentially. Therefore, liquid refrigerant remaining in the gas refrigerant is eliminated by heat transfer with the capillary tube.
