SEMINAR 43 (ADVANCED) Lubrication Effects Beyond the Compressor
Track: Advances in Refrigeration Systems and Alternative Refrigerants
Room: 225
Sponsor: 03.04 Lubrication, 03.03 Refrigerant Contaminant Control Chair: Joseph A. Karnaz, Member, CPI Fluid Engineering/Lubrizol, Midland, MI
Lubricants are an essential component to effective operation of air conditioning and refrigeration compressors which are exhaustively studied by compressor engineers and tribology experts. But there are other aspects to lubrication effects beyond the compressor which can also be key to effective operation and performance of air conditioning and refrigeration systems. This seminar presents examples of how the lubricant circulated from the compressor into the system can affect system components, oil management and overall system performance with existing and alternate refrigerants.
