摘要
在利用环保制冷剂R4 0 7C替代HCFC制冷剂R2 2的过程中有许多值得关注的技术问题 ,本文分析比较了R4 0 7C和R2 2的特性 ,特别研究了R4 0 7C的非共沸特性和相关应用技术。
Owing to its ozone depletion potential,refrigerant R22 is to be phased out according to some international treaties. Having participated the research work for developing environmentally friendly refrigerant R407C in Europe,a study on the issue of using R407C replacing R22 is made.
