摘要
本文初步探讨了液化石油气LPG(具有良好的环境相容性 )作为R2 2替代制冷工质的可行性。从热物性和制冷原理分析出发 ,实验研究了在制冷系统中用LPG替代R2 2的可行性 ,主要研究了LPG替代R2 2后制冷性能参数的变化。实验结果表明 ,LPG是一种有希望的R2 2的替代物。此外本文还分析了LPG制冷系统节能方面的性质。
The paper makes a preliminary study of LPG(Liquefied Petroleum Gas which has excellent environmental compatibility)as substitute for R22 on its feasibility in refrigerating system.Based on the theories of thermophysical properties and refrigeration,a series of tests of the performance of LPG as a suitable replacement for R22 in a refrigeration application were carried out.The studies cover the items relating to the replacement.The experiment shows promising prospects of the alternative-LPG.In addition,the property of energy saving in LPG refrigerating system is analysed.
