冷冻式压缩空气干燥器采用工质节能性分析

摘要

Refrigerated air dryer is one of the widely-used compressed air drying equipments.Traditional working fluid is R22 , and it is being alternatives due to the presence of R22 damaging effects of atmospheric ozone layer.In the working conditions for refrigerated compressed air dryers, five kinds of green alternative refrigerants ( R717, R290, R600A, R410A, R407C) were chose to perform thermodynamic calculation refrigeration and cycle analysis of energy consumption and efficiency.Useful conclusions were drawn by comparative analysis of the refrigerants with R22.%冷冻式压缩空气干燥器是广泛使用的压缩空气干燥设备之一。使用的传统工质为R22。由于R22存在对大气臭氧层的破坏作用，属被替代物质。在本文中，针对冷冻式压缩空气干燥器的工作条件，选择了5种 R22的绿色环保替代工质（R717， R290， R600A， R410A， R407C）进行制冷循环的热力计算，分析循环能耗和效率，并与R22对比分析，得出了有益的结论。
