| 摘 要： | 对双元非共沸工质喷射制冷循环做了可行性分析，利用ＰＲ方程对两种双元工质ＲＣ３１８／Ｒ１２３和ＲＣ３１８／Ｒ１４１ｂ进行了热力循环计算，对双元工质ＲＣ３１８／Ｒ１４１ｂ进行了喷冷循环实验，并与单元工程质Ｒ１４１进行了对比。理论分析和实验数据表明，通过选择合适的双元工质，在喷冷系统中不但可以提高其制冷品质，亦能同时提高制冷循环的能效比。

| Abstract: | In this paper,the feasibility of binary nonazeotropic mixtures used in a jet refrigeration cycle is analyzed.Using the PR equation of state,the thermodynamic calculations of binary mixtures RC318/R123 and RC318/R141b were completed. Then the experiments of RC318/R141b was conducted and compared with R141b. The results of the theoretical calculation and experiments indicate that an appropriate binary nonazeotropic mixture can not only improve the refrigeration quality of jet refrigeration,but also improve its performance coefficient in the same time. |
