Commercial refrigeration systems are searching for low-GWP refrigerant options due to the environmental responsibility and governmental regulations to limit the use of high-GWP refrigerants. Energy efficiency is very important in the refrigerant transition. The seminar covers commercial refrigeration systems using both natural refrigerant and low-GWP synthetics. How to increase R744 system efficiency when it operates at elevated ambient temperature? What is the R744 system with ejector technology? What is the Hybrid Geothermal R744 system? How to change the equipment design and control of low-GWP synthetics refrigeration to improve energy efficiency?
