混合工质R32/R134a替代家用电冰箱工质R12的理论与实验研究

Theoretical & Experimental Research on Using Mixture R32/R134a as the Substitution of R12 in Domestic Refrigerators

本文在Ｒ１３４ａ替代Ｒ１２的基础上提出用非共沸混合工质Ｒ３２／Ｒ１３４ａ替代Ｒ１２，理论分析和实验结果都证明Ｒ３２／Ｒ１３４ａ的主要制冷性能接近或优于Ｒ１２，而且与纯Ｒ１３４ａ替代方案相比，制冷量提高，能耗降低。

Abstract A non-azeotropic mixture R32/R134a is put forward as the substitution for R12 on the basis of using R134a to replace R12.The theoretical analysis and results of experiments have proved that R32/R134a has quite similar performances to those of R12.Compared to the program which only use R134a as the alternative,the refrigeration capacity of R32/R134a is improved and its energy consumption is decreased.
