Ozone-depletion potential (ODP) is a measurement of a refrigerant's ability to destroy ozone. Stated simply, refrigerants with chlorine have an ODP, while those without chlorine don't.CFCshave the highest ODP, followed by HCFCs. What refrigerant does not deplete the ozone layer?
(direct expansion) systems the evaporator has a different design than the flooded systems.the refrigerant is usually of HFC(hydrofluorocarbon) or similar type. 当早先描述冷冻剂在蒸发器比被充斥的systems.the冷冻剂(通常) HFC hydrofluorocarbon有一个不同的设计的DX直接扩展系统被带来煮沸在(evaporator....
