This abstract conducts a Life Cycle Climate Performance (LCCP) analysis, a holistic approach to estimate lifetime CO2eq emissions for one circuit of an industrial 230T, water-cooled, screw compressor chiller in drop-in tests conducted by Airconditioning, Heating and Refrigeration Institute (AHRI) with R134a, R450A, R513A, R516A, and R1234ze(E). With natural gas as a fuel source, and using R134a emissions as a baseline, total LCCP emissions were reduced by using R516A and R513A, respectively. R450A and R1234ze(E) capacity was reduced compared to R134a by approximately 15% and 25%, respectively.
