摘要
从高技术应用的要求出发，论述了纯质及氮－烃类混合工质的不足，用ＰＲ方程分析了成分配比对二元氮－氟里昂混合工质节流循环特性的影响，指出合理的成分配比对二元氮－氟里昂混合工质是十分必要的。并以不同温度下的△Ｈ＿Ｔ为目标函数，优化计算了一些二元氮，氟里昂低温混合工质的最佳成分配比。
In this paper according to the requirement of high technique, the disadvantage ofpure nitrogen and mixtures containing nitrogen and freon is suggested. The Peng-Robinson e-quation is used to analyze the influence of compositions on the J-T cycle of binary mixtureswith nitrogen and freon. It is pointed out that it is necessary to use reasonable composition inthese mixtures. And the optimum composition of these mixtures is indicated by using △HT atdifferent temperatures as objective function.
