Abstract
A mixed refrigerant composition includes carbon dioxide (R-744), 2,3,3,3-tetrafluoropropene (R-1234yf) and trifluoroiodomethane (R-13I1). A content of the carbon dioxide (R-744) ranges from 1 to 10 wt. % based on a total weight of the mixed refrigerant composition, and a sum of a content of the 2,3,3,3-tetrafluoropropene (R-1234yf) and a content of the trifluoroiodomethane (R-13I1) ranges from 90 to 99 wt. % based on the total weight of the mixed refrigerant composition. A boiling point at 1 atm of the mixed refrigerant composition ranges from −76 to −35° C.
