Author(s) : SUNDARESAN S. G.

Summary

R134A HAS THERMODYNAMIC PROPERTIES SIMILAR TO THOSE OF R12. SINCE CURRENTLY AVAILABLE MINERAL OILS ARE NOT MISCIBLE WITH R134A, A SERIES OF ALTERNATIVE LUBRICANTS IS BEING DEVELOPED TODAY. POLYALKYLENE GLYCOL AND ESTERS ARE EXAMPLES. THE PAPER REVIEWS RESULTS TO DATE FROM COMPRESSOR LIFE TESTING OF DIFFERENT TYPES OF POLYGLYCOLS.
