The present invention provides a freezing and generating system for a refrigerated cargo carrier using cold heat of liquefied natural gas, which includes: a storage tank in which liquefied natural gas is stored; a first heat exchanger in which the liquefied natural gas introduced through a first supply line from the storage tank is heat-exchanged with a single-phase refrigerant supplied through a first circulation line in a single-phase manner; a cold storage part in which the single-phase refrigerant heat-exchanged in the first heat exchanger in the single-phase manner to be cooled is cooled by flowing through the first circulation line; a second heat exchanger in which natural gas discharged from the first heat exchanger to be introduced through a second supply line is heat-exchanged with a two-phase refrigerator supplied through a second circulation line in a two-phase manner; and a low temperature power generating part generating power through a refrigeration cycle of the two-phase refrigerant heat-exchanged in the second heat exchanger, thereby improving environment friendly and economic feasibility.

    친환경성 및 경제성이 개선되도록, 본 발명은 액화천연가스가 저장된 저장탱크; 상기 저장탱크로부터 제1공급라인을 통해 유입된 액화천연가스가 제1순환라인을 통해 공급된 단상냉매와 단상 열교환되는 제1열교환기; 상기 제1열교환기에서 단상 열교환되어 냉각된 상기 단상냉매가 상기 제1순환라인을 통해 유동됨에 따라 냉각되는 냉동창고부; 상기 제1열교환기로부터 토출되어 제2공급라인을 통해 유입된 천연가스가 제2순환라인을 통해 공급된 이상냉매와 이상 열교환되는 제2열교환기; 및 상기 제2열교환기에서 열교환된 상기 이상냉매의 냉동사이클을 통하여 전력을 생산하는 저온발전부를 포함하는 액화천연가스의 냉열을 이용한 냉동운반선의 냉동 및 발전시스템을 제공한다.
