Abstract: A refrigeration system comprising: a heat absorption unit ( 300 ) for absorbing heat from a peripheral portion to fluid under a predetermined constant pressure; a first compression unit ( 410 ) for sucking the fluid discharged from the heat absorption unit ( 300 ) and compressing; an intermediate cooling unit ( 500 ) for cooling the fluid compressed in the first compression unit ( 410 ); a second compression unit ( 420 ) for re-compressing the fluid discharged from the intermediate cooling unit ( 500 ); a heat radiating unit ( 100 ) for radiating heat from the fluid compressed in the second compression unit ( 420 ) and discharged to a peripheral portion under a predetermined constant pressure; an expansion unit ( 200 ) for lowering pressure of the fluid which passed through the heat radiating unit ( 100 ) by an adiabatic expansion and driving the first and second compression units by work generated from the expansion; and a cooling flow path ( 510 ) for passing the fluid discharged from the expansion unit ( 200 ) through the intermediate cooling unit ( 500 ).
