선박용 재액화 시스템의 냉매 사이클 압력 조절 시스템이 개시된다. 본 발명의 선박용 재액화 시스템의 냉매 사이클 압력 조절 시스템은, 선박의 재액화 시스템에 마련되며 저장탱크로부터 증발가스를 공급받아 냉각하는 열교환기; 상기 열교환기에서 상기 증발가스를 냉각시키는 냉매가 순환하는 냉매순환라인과, 상기 냉매순환라인에 마련되며 상기 열교환기에서 상기 증발가스를 냉각시키고 배출되는 냉매를 압축하는 냉매압축기와, 상기 냉매압축기에서 압축 후 열교환기를 거쳐 냉각된 냉매를 팽창 냉각시켜 열교환기의 냉매로 공급하는 팽창기를 포함하는 냉매 사이클; 상기 냉매 사이클로 충진될 냉매를 저장하는 인벤토리 탱크; 상기 인벤토리 탱크로부터 상기 냉매압축기 전단으로 연결되어 상기 냉매 사이클로 냉매를 보충하는 냉매공급라인; 상기 냉매압축기 후단에서 상기 인벤토리 탱크로 연결되어 상기 냉매 사이클의 냉매를 상기 인벤토리 탱크로 배출하는 냉매배출라인; 및 상기 냉매배출라인에서 분기되는 압력조절라인:을 포함하며, 상기 냉매배출라인 또는 압력조절라인으로 상기 냉매 사이클의 냉매를 배출시켜 상기 냉매 사이클을 감압할 수 있는 것을 특징으로 한다.

    Disclosed herein is a refrigerant cycle pressure control system for a reliquefaction system for a ship. The refrigerant cycle pressure control system includes: a heat exchanger provided to the reliquefaction system and cooling boil-off gas received from a storage tank; a refrigerant cycle including a refrigerant circulation line through which a refrigerant is circulated to cool the boil-off gas in the heat exchanger, a refrigerant compressor disposed on the refrigerant circulation line and compressing the refrigerant discharged from the heat exchanger after cooling the boil-off gas in the heat exchanger, and an expander expanding and cooling the refrigerant compressed by the refrigerant compressor and having been cooled through the heat exchanger and supplying the expanded and cooled refrigerant to the heat exchanger; an inventory tank storing the refrigerant to be charged to the refrigerant cycle; a refrigerant supply line connecting the inventory tank to an upstream side of the refrigerant compressor to replenish the refrigerant cycle with the refrigerant; a refrigerant discharge line connecting a downstream side of the refrigerant compressor to the inventory tank to discharge the refrigerant from the refrigerant cycle to the inventory tank; and a pressure regulation line branched off of the refrigerant discharge line, wherein the refrigerant cycle is depressurized by discharging the refrigerant from the refrigerant cycle through the refrigerant discharge line or the pressure regulation line.
