refrigerants, low GWP, air conditioning, chiller
Refrigerants with low environmental impact have been developed as replacements for R410A in stationary air conditioning applications. Non-flammable and mildly flammable low global warming potential (GWP) refrigerants, have been evaluated in representative R410A residential equipment. This study discusses the performance these replacements for ambient temperatures ranging from 28oC to 46oC. Replacements for R410A and R134a are also discussed for high pressure and medium pressure chiller applications respectively. Results obtained from system simulation are discussed in detail showing the benefits of using these new fluids.
