Abstract
The mixed refrigerant composition according to embodiments of the present disclosure includes carbon dioxide (R-744), trifluoroiodomethane (R-13I1), and 1,1-difluoroethane (R-152a), wherein a sum of contents of the trifluoroiodomethane (R-13I1) and the 1,1-difluoroethane (R-152a) based on a total weight of the mixed refrigerant composition may be 60 wt. % or more and less than 100 wt. %. Accordingly, environmental pollution caused by the mixed refrigerant composition may be suppressed, and the cooling performance of the mixed refrigerant composition may be improved.
Claims21
1-17. (canceled)
A mixed refrigerant composition comprising:
- a natural refrigerant comprising 3% to 10% by weight of carbon dioxide (R-744);
- and
- at least 60% by weight or more of a mixture of fluorinated refrigerants, wherein the mixture of fluorinated refrigerants consists of a mixture of trifluoroiodomethane (R-13I1) and 1,1-difluoroethane (R-152a).
A refrigerant composition, wherein the refrigerant in the composition consists of a mixture of two or more refrigerants selected from the group consisting of one or more natural refrigerants and one or more hydrofluorocarbon (HFC) refrigerant, wherein the refrigerant comprises (a) at least 3% to 10% by weight of carbon dioxide, (b) trifluoroiodomethane (R-13I1);
- and (c) 1,1-difluoroethane (R-152a).
A mixed refrigerant composition comprising:
- 3% by weight or more of carbon dioxide (R-744) based on the total weight of the mixed refrigerant composition;
- trifluoroiodomethane (R-13I1);
- and
- 1,1-difluoroethane (R-152a);
- wherein:
- the mixed refrigerant composition comprises 60% by weight or more of the R-13I1 and the R-152a, based on the total weight of the mixed refrigerant composition, the ratio of the R-13I1 to the R-152a is 1.4 to 3.95, and the ratio of the R-744 to the and R-152a is 0.01 to 0.3.
