Advancing Ozone and Climate Protection Technologies Conference
I recently made a trip to Bangkok to speak at the Advancing Ozone and Climate Protection Technologies—Next Steps Second International Conference on June 29-30. The conference addressed alternatives for air conditioning, foams, refrigeration, and other sectors, with a special focus on standards for climate-friendly alternatives.
On the first day of the conference, I presented “Promising Low-GWP Options in Air Conditioning and Refrigeration Applications” which covered recent advances in the research for new refrigerants and the role Life Cycle Climate Performance plays for both air conditioning and refrigeration systems. A variety of solutions that utilize low GWP refrigerants for air conditioning and refrigeration applications were showcased at the conference. For the air conditioning systems, a range of Copeland Scroll™ compressors operating with R32 refrigerant was exhibited along with expansion valves and system protection components. These compressors can be used with either liquid or vapor injection to provide system design flexibility and optimization of system performance and cost.
For the refrigeration market, the Copeland™ Stream compressor for R744 refrigerant was displayed. This 4-cylinder compressor for CO2 transcritical applications is designed for medium temperature cascade and booster systems. It features CoreSense™ diagnostics, allowing for compressor protection, predictive diagnostics, communication with Emerson’s supervisory controls, and stepless capacity modulation by variable frequency drive from 25 to 75 Hz. In addition, a range of hermetic reciprocating compressors for R290 that are optimized for maximum performance were on display.
