Industry migration to lower GWP refrigerants requires an evaluation of lubricants and compressor lubrication. This seminar examines what is needed in lubricant design when implementing change from different refrigerant chemistry. Industry experts in lubricant strategy and compressor lubrication explore what is required to maintain effective system reliability and efficiency through examination of system chemistry, material compatibility and lubricant-refrigerant interaction which helps determine proper bearing lubrication. Techniques in lubricant evaluation, examples of lubricant options for next generation lower GWP refrigerants and optimized compressor lubrication are identified.
