Commercial refrigeration systems are searching for lower GWP refrigerant options. Systems with small charge size are moving towards natural refrigerants, such as CO2 in bottle coolers and R-290 in self-contained commercial ice machines. Larger systems are investigating low GWP synthetic refrigerants. What are the important design issues for natural refrigerants? What are the thermal and capacity performances of the low GWP synthetics? Are the energy efficiencies of all these lower GWP options beneficial to lowering the total GWP impacts compared to HFC systems?
