Comparison Between Fluorinated Ether Azeotropic Mixtures HFE-143a/HFE-218 as Refrigerant And Some Other HCFC-22 Alternatives
【摘要】 利用饱和蒸气压与温度关系方程式,对氟化醚类混合物HFE-143a/HFE-218做了饱和蒸气压力-温度计算,并将计算结果绘制出相应图表,进而和目前几种HCFC-22替代物的性能作比较,分析了氟化醚类混合物作为制冷剂HCFC-22替代物的可行性和优越性。
【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.
