摘要
对几种纯质和两个二元物系Ｒ２２／Ｒ１４２ｂ、Ｒ２２／Ｒ１５２ａ进行了以ＰＶＴｘ实验数据和改进型ＣＳＤ状态方程为基础的热力学性质计算和理论制冷循环分析．结果表明，Ｒ２２／Ｒ１４２ｂ为近理想溶液，Ｒ２２／Ｒ１５２ａ为近共沸溶液；纯质及Ｒ２２／Ｒ１４２ｂ物系的理论制冷循环性能与Ｒ１２相比互有优缺，而Ｒ２２／Ｒ１５２ａ物系的主要性能指标超出Ｒ１２．
The thermodynamic properties and theoretical refrigeration performances of several alternatives to R12 were investigated by means of PVTx measurements and a modified form of CSD equation of state with simple mixing rules. It is shown that the binary mixture, R22/R152a, is a promising candidate to substitute R12, owing to its higher COP and q v in a wide composition range.
