New Development and Some Problems in Alternative Technology of CFC─12 Using HFC─134a
Zheng Aiping (Department of Training Course)
An overview of the new development is provided when HFC─134a is used as an Alternatine for CFC─12. Some problems, such as heat transfer performance of HFC─134a, lubricants compatibility. drying agents and leakage detection of HFC─134a, arc discussed. Some proposals concerning HFC─134a as a substitution of CFC─12 in China are put forward.
