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.

    Disclosed herein is a refrigerant charging system for a reliquefaction system for ships. The refrigerant charging system includes: a reliquefaction system provided to a ship and reliquefying boil-off gas generated in a liquefied gas storage tank by compressing the boil-off gas and subjecting the compressed boil-off gas to heat exchange with refrigerant supplied to a heat exchanger while circulating along a refrigerant circulation line; a buffer tank storing utility N2 to be supplied to the ship; a booster compressor receiving the utility N2 from the buffer tank, compressing the received utility N2, and supplying the compressed utility N2 to the refrigerant circulation line; and a first load-up line along which the utility N2 is supplied from the buffer tank to the refrigerant circulation line without passing through the booster compressor, wherein, upon initial charging in a non-operation state of the reliquefaction system, the refrigerant circulation line is charged with refrigerant by supplying the utility N2 from the buffer tank to the refrigerant circulation line along the first load-up line by a pressure differential between the refrigerant circulation line and the buffer tank.
