Chlorine-free refrigerant mixt. - based on tri:fluoro:methane and hepta:fluoro:propane |
| 摘要 |
A refrigerant mixt., for use in compression refrigerating circuits, consists of 12-25 wt.% trifluoromethane (R23,CHF3), 68-86 wt.% hepta-fluoropropane (R227,C3HF7) and 2-7 wt.%, ancillary component, pref. hydrocarbon, esp. dimethylether (DME C2H6O), propane (R270,C3H8) or propylene (R1270,C3H6). ADVANTAGE - The refrigerant mixt. is chlorine-free, has a wide temp. range of phase transformation and permits low pressure ratios.
