An ammonia gas re-liquefication system for a vessel is disclosed. In accordance with an embodiment of the present invention, the ammonia gas re-liquefication system for a vessel includes: an absorption tower causing ammonia gas used as a refrigerant to react to water to produce ammonia water; a regeneration tower receiving the ammonia water from the absorption tower and separating the ammonia water into water and ammonia gas; a re-liquefaction unit receiving the separated ammonia gas and using the ammonia gas as a refrigerant, while cooling the refrigerant with liquefied ammonia supplied from a fuel tank, and re-liquefying the ammonia gas discharged from the fuel tank through a heat exchange with the refrigerant; an ammonia transfer line connecting the absorption tower with the regeneration tower; a pre-mixing tank storing a mixture of gasified or liquefied ammonia with water; and a refrigerant filling line supplying the mixture stored in the pre-mixing tank for refrigerant replenishment to the rear end of the absorption tower of the ammonia transfer line. Therefore, the present invention is capable of effectively replenishing ammonia used as a refrigerant.

    선박의 암모니아가스 재액화시스템이 개시된다. 본 발명의 실시 예에 따른 선박의 암모니아가스 재액화시스템은 냉매로 사용된 암모니아가스에 물을 반응시켜 암모니아수를 생성하는 흡수탑; 흡수탑으로부터 암모니아수를 공급받아 물과 암모니아가스로 분리시키는 재생탑; 분리된 암모니아가스를 공급받아 냉매로 사용하되, 냉매를 연료탱크로부터 공급된 액상의 암모니아를 이용하여 냉각시키고, 냉매와의 열교환에 의해 연료탱크로부터 배출된 암모니아가스를 재액화하는 재액화부; 흡수탑과 재생탑을 연결하는 암모니아이송라인; 기상 또는 액상 암모니아와 물의 혼합물을 저장하는 예비믹싱탱크; 및 냉매 보충을 위해 예비믹싱탱크에 저장된 혼합물을 암모니아이송라인의 흡수탑 후단으로 공급하는 냉매충전라인;을 포함한다.
