This seminar presents the most recent study of commercial refrigeration system using natural refrigerants such as CO2, ammonia propane, ammonia and R600a and low GWP synthetic blends. How to successfully convert light commercial refrigeration applications originally designed for R134a to natural refrigerants? What is performance and energy consumption of a low-charge ammonia chiller installation and a propane freezer compared to traditional HFC systems? How to improve the efficiency of stand-alone applications with low GWP synthetic refrigerants?
