低GWP不饱和氟化烯烃替代HFC的前景预测
Foreground forecast of substituting HFCs with low GWP unsaturated fluorinated olefins
摘要：
美国J S Brown博士等人对于大量候选的替代制冷剂，提出了在仅知其标准沸点温度和分子结构式的条件下，预测估算其热力学特性与性能的简捷方法，论证了这种方法的误差与有效性，并分析了8种氟化丙烯同分异构体的热力学特性及R1234yf与R1234ze(Z)的具体应用。根据已收集到的资料总结了近年来这些研究成果，供国内同行了解与参考。

Abstract：
American Dr J S Brown, et al present a new method to easily and quickly predict the thermodynamic characteristic and performance of an alternative refrigerant with only its normal boiling point temperature and molecular structure known, demonstrate the error and effectiveness of this method, and analyse thermodynamic characteristics of eight fluorinated propylene isomers and specific applications of R1234yf and R1234ze(Z). Provides a summarization of the related research achievements for domestic colleagues to understand and use for reference.
Keywords:unsaturated fluorinated olefin, unsaturated fluorinated propylene, CFC, HCFC, HFC, HFO, normal boiling point temperature
