Copyright 2004-2011 Aspose Pty Ltd.Copyright 2004-2011 Aspose Pty Ltd.R410A新冷媒是由R32（二氟甲烷）和R125（五氟乙烷）组 成的混合物，主要由氢、氟和碳元素组成（表示为HFC)， R410A是目前国际公认的用来替代R22最合适的冷媒。其主要特点有： R410A外观无色，不浑浊，易挥发，沸点为-51.6，凝固点 为-155； 不破坏臭氧层。其分子式中不含氯
5、元素故不破坏臭氧层毒性 极低，容许浓度和R22同样都是1000ppm。 不可燃。空气中的可燃极性为0。R410A制冷剂性质简介Evaluation only.Evaluation only.

7、统，可以采用较小 体积的冷凝器和蒸发器，成本更低，而且最高可达30% 的制冷剂充注减少量。制冷剂充注量的减少不仅可以降 低成本，而且还能提高整个系统的可靠性。 水分溶解性与R22几乎相同。 R22使用的是矿物油，R410A使用的是POE合成油。Evaluation only.Evaluation only.
