Use of a gas mixture selected from the group consisting of: - trifluoroiodomethane (CF3I) at a concentration of from 85% to 99% by weight and fluoroethane (R161) at a concentration of 15% to 1% by weight , and - trifluoroiodomethane (CF3I) at a concentration of 90% to 99% by weight and a gas selected from the group consisting of propylene, pentafluoroiodoethane, pentafluoroethane, and mixtures thereof at a concentration of 10% to 1% by weight, the concentration referring to the total weight of the mixture, as a refrigerant and/or propellant as a replacement for or alternative to R134a and/or propellants replacements for or alternatives to R134a containing HFCs (hydrofluorocarbons), HFOs (hydrofluoroolefins) and HFE (hydrofluoroethers). |
