美国JS 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。 For a large number of alternative refrigerants, JS Brown of the United States proposed a simple method of predicting and estimating its thermodynamic properties and properties under the condition of only knowing its normal boiling temperature and molecular structure, and demonstrated the error and effectiveness of this method The thermodynamic properties of eight fluorinated propylene isomers and the specific applications of R1234yf and R1234ze (Z) were also analyzed. Based on the collected data, we summarize these research results in recent years for domestic counterparts to understand and reference.
