New type lube oil for HFC134a compressor system.

Author(s) : TAKENO T., MIZUI K., TAKAHATA K.

Summary

Among several possibilities polyalkylene glycol (PAG) derivatives and carboxylates (esters) have been identified as candidates for car air-conditioners and for refrigerators respectively. However, it is clear that these candidates have weaknesses: PAGs demonstrate poor miscibility of high viscosity types and high water absorption. Esters cause corrosion due to the generation of caboxylic acid upon degradation. The authors' research has resulted in a new chemistry based on carbonates which overcome the shortcomings of the current candidate lube oils for both refrigerator and car air-conditioner compressors.
