| 摘 要： | HFCs被认为可以作为CFCs的长期替代工质，但使用HFCs会加剧温室效应，本文通过理论分析认为HFCs的温室效应完全可以通过提高此类工质的能效比来减弱，并筛选出几种有望替代R12的纯质及二元混合工质进行了理论分析和模拟计算，选择R134a和几种不同配比的R32／R134a二元混合工质进行了模拟冷水机组运行工况的制冷循环实验。结果表明一定配比的非共沸二元混合工质R32／R134a可以替代R12应用于冷水机组以及与冷水机组工况相娄似的中小型冷藏库．

| Abstract: | HFCs has been a kind of long term substitutes of CFCs.However,using HFCs will contribute to the global greenhouse effect.The thermal properties and cycle performance of several alternative refrigerants are compared by the theoretical analysis and simulative computing.And three kinds of refrigerants have been chosen to do modulation experiment.The result shows that nonazeotropic mixture refrigerant R32/R134a of certain proportion can substitute for refrigerant R12 applied in chilled water refrigerating system as well as cold store with small or medium capacity. |
