Zusammenfassung:The present invention relates to a closed type regasification system for liquefied gas and a method for the same and, more specifically, to an indirect heat exchange and closed type regasification system for liquefied gas and a method for the same, which indirectly exchange heat of steam and liquefied gas by a propane refrigerant and regasify the liquefied gas using thermal energy of the steam. According to the present invention, the closed type regasification system for liquefied gas includes: a first heat exchanger exchanging the heat of the liquefied gas and a thermal medium and gasifying the liquefied gas; and a second heat exchanger exchanging the heat of the steam and the thermal medium condensed by the heat exchange of the first heat exchanger and evaporating the thermal medium. The first heat exchanger is installed in the upper part than the second heat exchanger. The thermal medium of a liquid state condensed by the heat exchange in the first heat exchanger is circulated to the second heat exchanger by the gravity. 본 발명은 폐쇄형 액화가스 재기화 시스템 및 방법에 관한 것으로, 보다 구체적으로는, 스팀의 열에너지를 이용하여 액화가스를 재기화시키되, 스팀과 액화가스는 프로판 냉매를 매개체로 하여 간접 열교환시키는, 간접 열교환식 폐쇄형 액화가스 재기화 시스템 및 방법에 관한 것이다. 본 발명에 따른 폐쇄형 액화가스 재기화 시스템은, 액화가스와 열매체를 열교환시켜 액화가스를 기화시키는 제1 열교환기; 및 제1 열교환기에서 열교환에 의해 응축된 열매체와 스팀을 열교환시켜 열매체를 증발시키는 제2 열교환기;를 포함하고, 상기 제1 열교환기는 제2 열교환기보다 상부에 위치하고, 상기 제1 열교환기에서 열교환에 의해 응축된 액체 상태의 열매체는 중력에 의해 제2 열교환기로 순환되는 것을 특징으로 한다.
