Abstract: PURPOSE: A liquefaction apparatus, a liquefaction method, and a fluid transferring system including the same are provided to improve the operational energy of the liquefaction apparatus by liquefying carbon dioxide through multi-stepped compressing and expanding processes. CONSTITUTION: A liquefaction apparatus(110) is composed of a compressing unit(210), a condenser(220), and an expanding unit(230). The compressing unit gradually compresses gaseous first feed stream using a plurality of compressors such that ensures a first target pressure at the first feed stream. The condenser condenses the first feed stream of the first target pressure into liquid second feed stream. The expanding unit eliminates gaseous components from expanded second feed stream at each expanding step. The eliminated gaseous components are supplied into the compressing unit to cool the first feed stream. [Reference numerals] (AA) First feed stream; (BB) Second feed stream
