Abstract:
A refrigerator having improved cooling system comprising:a compressor;a condenser for condensing a refrigerant from the compressor into a liquid state;an evaporator for evaporating the liquid refrigerant into a gaseous state through heat exchange with air within a storage area;a capillary tube positioned between the evaporator and the condenser;a connection pipe positioned between the evaporator and the compressor; andfirst and second coupling members, positioned between the evaporator and the connection pipe and positioned between the connection pipe and the compressor, respectively, for directing the capillary tube to the inside of the connection pipe,each of the coupling members comprising a first coupling element functioning as a passage for the refrigerant, a second coupling element functioning as a passage for the capillary tube, and a connecting element for connecting the first coupling element and the second coupling element,the axes of the second coupling elements of the coupling members extending parallel to the axes of the respective first coupling elements of the coupling members,the first coupling element of the second coupling member having a first end screw-coupled to an inlet of the compressor and a second end screw-coupled with the connection pipe,the first coupling element of the first coupling member having a first end connected to an outlet of the evaporator and a second end screw-coupled to the connection pipe, andthe second coupling element of each of the coupling members having an open end sealingly coupled to the capillary tube and a closed end.
