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.

    A refrigerant charging system for a reliquefaction system for a ship is disclosed. The refrigerant charging system for a reliquefaction system for a ship, according to the present invention, comprises: a reliquefaction system which is provided in a ship to reliquefy boil-off gas, generated from a storage tank having liquefied gas stored therein, by compressing the boil-off gas and performing, in a heat exchanger, heat exchange between the compressed boil-off gas and a refrigerant circulated through a refrigerant circulation line; a buffer tank in which utility N2 to be supplied to the ship is stored; a boosting compressor which is supplied with the utility N2 from the buffer tank and compresses and supplies same to the refrigerant circulation line; and a first load-up line which supplies the utility N2 from the buffer tank to the refrigerant circulation line while bypassing the boosting compressor, wherein during initial charging in a state where the reliquefaction system is stopped, the utility N2 is supplied from the buffer tank to the refrigerant circulation line through the first load-up line by a differential pressure between the refrigerant circulation line and the buffer tank, and thereby the refrigerant is charged.
