Low GWP Refrigerants, Low GWP Replacements for Air Conditioning Applications
Refrigerants with low environmental impact have been developed as replacements for R22 and R410A in air conditioning applications. L-20 and L-41 have been evaluated in representative residential equipment. This study discusses the performance at high ambient temperatures (warm climate) and potential design changes. In addition, 1233zd and 1234ze have been evaluated as replacements for R123 and R134a in low and medium pressure chiller applications. Theoretical and experimental results are discussed in detail showing the benefits of using these new fluids.
