ShareA study on lubricity of polyolester for alternative refrigerant HFC-134a.
Author(s) : ISHIDA Y., NISHIWAKI F., IKOMA M.
Summary
The paper presents the experimental research into the evaluation of lubricity for polyolester (POE) lubricant with R134a refrigerant in rotary and reciprocating compressors for household refrigerators. In order to evaluate the lubricity for POE lubricant with R134a refrigerant, the authors conducted 4-balls wear tests in the mixing environment of POE lubricant and R134a refrigerant. In the study, the effects of the weight fraction of the refrigerant on the lubricity for POE lubricant with R134a refrigerant were clarified. Wear configurations were also studied, including corrosive configuration, linked with metal fluoride and carboxylic acid salt, generated by R134a decomposition.
