The Evaluation of PVE (Poly Vinyl Ether) as a Lubricant for Air Conditioning System Converted from HCFC22 to Either HFC410A or HFC407C

Type: conference-paper
Abstract: PVE (Polyvinyl ether) has been developed as a lubricant for air conditioning systems which use an alternative refrigerant such as HFC407C and HFC410A instead of HCFC22.Because HCFC22 will no longer be used as a refrigerant in Japan after 2020, Japanese OEMs have started to convert their existing HCFC22 systems to an alternative refrigerant system, either HFC410A or HFC407C.During the conversion process, it is inevitable that the PVE will be mixed with the residual Mineral oil (MO) which was used in the HCFC22 system.Because of this, extensive evaluation has been conducted on the oil mixture between PVE and Mineral oil to determine it's suitability in a converted system.The evaluations that were conducted include: Solubility, Thermal stability, Lubricity, Compatibility with system materials and the analysis data of used oil in a converted system.The evaluation results support that PVE is a very suitable refrigeration lubricant for air conditioning systems converting from HCFC22 to either HFC410A or HFC407C refrigerant.
