| Abstract: |
| The properties of fluorinated ether mixtures HFE-143a/HFE-218 were calculated using the vapor pressure and temperature equations. Comparison between these mixtures and the other HCFC-22 alternatives was conducted. The feasibility and superiority of these mixtures was analyzed. The result shows that the mixtures HFE-143a/HFE-218 can be used as refrigerants to replace HCFC-22. |
