R-22制冷剂(二氟一氯甲烷)

R22( Freon22,二氟一氯甲烷 Chlorodifuoromethane),分子式CHClF2,分子量86.47。R-22在常温下为无色,近似无味的气体,不燃烧、无腐蚀、毒性极微,加压可液化为无色透明的液体,为 HCFC 型制冷剂。R-22的化学稳定性和热稳定性均很高,特别是在没有水份存在的情况下,在200℃以下与一般金属不起反应。在水存在时,仅与碱缓慢起作用。但在高温下会发生裂解。
R-22适用于家用空调、中央空调和其它商业制冷设备。也可用作聚四氟乙烯树脂的原料和灭火剂1121的中间体。
适用的冷冻机油有:烷基苯合成油AB(Alkybenzene)、多元醇酯合成油POE(Polyol Ester)、环烷基矿物油MO(Mineral oil)。

各种制冷剂压焓图
You can draw log(p)-h diagrams for the following refrigerants:
R11, R12, R13, R14, R21, R22, R23, R113, R114, R123, R134a, R152a, R290, R401A, R401B, R401C, R402A, R402B, R404A, R406A, R407A, R407B, R407C, R408A, R409A, R410A, 410B, R500, R502, R507, R508A, R600, R600a, R717, R718, R744, RC318
Before you draw a log(p)-h diagram you have to fill out a dialog, where you select the refrigerant and other values.
After you have drawn the diagram you can save it to disk for later use, print the plot or export the image to Bitmap or Metafile format.
Furthermore you can draw and get calculated data for 4 types of predefined cycles, or you can draw the cycles you want by drawing polylines in the plot.
