Disclosed is an evaporation gas reliquefaction system capable of removing condensed or coagulated lubricating oil simply and economically. The evaporation gas reliquefaction system includes: a compressor for compressing evaporation gas; a heat exchanger for exchanging heat with the evaporation gas compressed by the compressor using evaporation gas before being compressed by the compressor as refrigerant to cool the compressed evaporator gas; a decompression device mounted at a rear end of the heat exchanger to decompress a fluid cooled by the heat exchanger; a bypass line for making evaporation gas to be used as refrigerant in the heat exchanger bypass the heat exchanger at the front end of the heat exchanger in order to supply the evaporation gas to the compressor; and a bypass valve mounted on the bypass line to control a flow rate of a fluid. If pressure of the evaporation gas supplied to the compressor is lower than suction pressure required for the compressor, the bypass valve is opened partially or fully.

    증발가스 재액화 시스템이 개시된다. 상기 증발가스 재액화 시스템은, 증발가스를 압축시키는 압축기; 상기 압축기에 의해 압축된 증발가스를, 상기 압축기에 의해 압축되기 전의 증발가스를 냉매로 사용하여 열교환시켜 냉각시키는 열교환기; 상기 열교환기 후단에 설치되어, 상기 열교환기에 의해 냉각된 유체를 감압시키는 감압장치; 상기 열교환기에서 냉매로 사용될 증발가스를, 상기 열교환기 전단에서 상기 열교환기를 우회시켜 상기 압축기로 공급하는 우회라인; 및 상기 우회라인 상에 설치되어 유체의 유량 및 개폐를 조절하는 우회밸브;를 포함하고, 상기 압축기로 공급되는 증발가스의 압력이, 상기 압축기가 요구하는 흡입 압력 조건보다 낮은 경우, 상기 우회밸브가 일부 또는 전부 열리는 것을 특징으로 한다.
