Composition comprising difluoromethane, tetrafluoropropene and carbon dioxide and use thereof |
| abstract |
According to the present invention, refrigerant compositions are disclosed. The composition comprises a refrigerant mixture consisting essentially of HFC-32, HFO-1234yf and CO2 . The compositions can be used as refrigerants in methods for refrigeration and heating, in methods for replacing refrigerant R-410A, and as refrigerants in refrigeration systems, air conditioning systems or heat pump systems. These inventive compositions match the cooling capacity of R-410A to within 20% with a GWP of less than 250 or less than 200. |
