Disclosed is a refrigerant charging system for a reliquefaction system in a ship. According to the present invention, the refrigerant charging system for a reliquefaction system in a ship comprises: the reliquefaction system arranged in the ship, compressing boil-off gas generated from a storage tank storing liquefied gas, and reliquefying the boil-off gas by making the boil-off gas exchange heat with a refrigerant circulating in a refrigerant circulation line; a buffer tank storing a utility N_2 to be supplied to the ship; a boosting compressor receiving the utility N_2 from the buffer tank and compressing and supplying the utility N_2 to the refrigerant circulation line; and a first load up line detouring the boosting compressor and supplying the utility N_2 from the buffer tank to the refrigerant circulation line. When initially charging with the reliquefaction system stopped, the refrigerant is charged by supplying the utility N_2 from the buffer tank to the refrigerant circulation line through the first load up line by the differential pressure between the refrigerant circulation line and the buffer tank. Therefore, initial installation cost can be reduced.

    선박용 재액화 시스템의 냉매 충진 시스템이 개시된다. 본 발명의 선박용 재액화 시스템의 냉매 충진 시스템은, 선박에 마련되며 액화가스가 저장된 저장탱크로부터 발생하는 증발가스를 압축하고 냉매순환라인을 순환하는 냉매와 열교환기에서 열교환시켜 재액화하는 재액화 시스템; 상기 선박에 공급될 유틸리티 N2를 저장하는 버퍼탱크; 상기 버퍼탱크로부터 유틸리티 N2를 공급받아 압축하여 상기 냉매순환라인으로 공급하는 부스팅압축기; 및 상기 부스팅압축기를 우회하여 상기 버퍼탱크로부터 상기 냉매순환라인으로 유틸리티 N2를 공급하는 제1 로드업라인:을 포함하고, 상기 재액화 시스템의 정지 상태에서 초기 충진 시, 상기 냉매순환라인과 상기 버퍼탱크의 차압에 의해 상기 제1 로드업라인을 통해 상기 버퍼탱크로부터 상기 냉매순환라인으로 유틸리티 N2를 공급하여 냉매를 충진하는 것을 특징으로 한다.
