SharePolybasic esters: novel synthetic lubricants designed for use in HFC compressors.
Author(s) : LILJE K. C., SABAHI M., HAMID S.
Summary
Polyalkylene glycol and polyol ester lubricants have been extensively evaluated in various refrigeration applications and are being used commercially. Novel synthetic lubricants have been developed based on polybasic esters (PBE) resulting from malonate-acrylate Michael adducts. These lubricants were designed to address problems encountered in current HFC systems. PBE-based fluids show desired miscibility with R134a and other HFC blends, excellent hydrolytic stability, no copper plating (even in wet systems), and excellent lubricity. Key physical property data, bench and compressor test results, and compatibility study results are presented.
