HEAT TRANSFER FLUIDS COMPRISING DIFLUOROMETHANE, PENTAFLUOROETHANE, TETRAFLUOROPROPENE AND OPTIONALLY PROPANE |
| 摘要 |
A composition includes between 11 and 13 wt. % of difluoromethane; between 58 and 62 wt. % of pentafluoroethane; between 18 and 29 wt. % of tetrafluoropropene; and between 0 and 7 wt. % of propane. The tetrafluoropropene can be 1,3,3,3-tetrafluoropropene or 2,3,3,3-tetrafluoropropene. The composition can be used as a heat transfer fluid in a vapour compression circuit. |
