Author(s) : MATSUMOTO T., KANEKO M., TAMANO M.

Summary

For global environmental protection, HCFC22 refrigerant has determined no production and no importing in America since 2010, because the shift from HCFC22 systems to the HFC refrigerants systems will expect in earnest. PVE (Polyvinylether) is being examined as lubricants for air conditioning systems which use alternative refrigerants such as HFC refrigerants instead of HCFC22. On the other hand, since 1998, most of Japanese OEMs have already started to supply air conditioning systems with HFC refrigerants and PVE. In this report, it is introduced that PVE is the most suitable refrigeration lubricant for air conditioning systems with HFC refrigerants from view point, as follows. First is the chemical and physical properties (Solubility, Thermal stability, Lubricity, Volume Resistivity), second is the result of endurance test. In addition, the authors will present the evaluation results of stability tests conducted on the oil mixture of PVE and mineral oil, because there is possibility that PVE contaminates with the residual mineral oil which was used in the HCFC22 system.
