摘　　要：主要利用NIST8.0软件,针对R23/R134 a,R23/R600 a,R23/R125,R23/R14等二元混合工质在Linde-Hampson循环下进行了理论分析,设计一套可制得-60℃的单级压缩节流回热循环系统。通过对工质成分特性分析对比,研究其对循环的热力学性能的影响规律,得到了最佳制冷剂组合。This paper was concerned with the theoretical analysis on Lind-Hampson cycle using the refrigerant mixture of R23/R134a R23/R600a,R23/R125,R23/R14 by nist 8.0,and designed a refrigeration regenerative cycles using mixed refrigerants and single compressor which have been obtained at the temperature of-60℃.The best mixed refrigerants was acquired under the study of thermodynamic property influence rhythm by analyzing and contrasting mixed refrigerants features.
