Summary

This is the 14 slide PowerPoint presentation of Juhasz and Kontomaris' paper on R1336mzz(Z). R-1336mzz(Z) (cis-CF3CH=CHCF3) is a non-flammable HydroFluoro-Olefin (HFO) with an ultra-low GWP of 2. It has shown surprisingly high chemical stability at high temperatures, despite the unsaturated chemical bond in its molecular structure. It is the main component of R-514A, an azeotropic, nonflammable replacement for HCFC-123 in centrifugal chillers. It could also enable industrial heat pumps delivering higher heating temperatures (up to or over 150 oC) and higher energy efficiency than incumbent fluids. R-1336mzz(Z) and R-514A properties will be reviewed, new thermodynamic and chemical stability data will be presented, and performance in chillers and high temperature heat pumps will be evaluated.
