Résumé

A new olefin refrigerant, R1233zd(E), has been identified for use in HVAC chillers. R1233zd(E) is being considered for a number of applications including use as, but not limited to, a solvent, a foam blowing agent, a refrigerant in large centrifugal chillers, and a refrigerant in heat recovery equipment. R1233zd(E) provides specific environmental and safety features of interest including very short atmospheric life (26 days), no impact to stratospheric ozone, ultra-low Global Warming Potential (GWP of 1), no measured secondary adverse environmental impacts (such as increases in ground level ozone or trifluoroacetic acid (TFA)), low toxicity, and non-flammability. This paper will provide an overall assessment of applying this new olefin refrigerant in centrifugal water cooled chillers. System performance characteristics will be compared to a number of refrigerants including R134a, R1234ze(E), R245fa, and R123. LCCP emission profiles will be compared. Reliability indicators, such as material compatibility and chemical stability, will be provided.
