O.3.3.4 Novel Working Fluid, HFO-1336mzz(E), for Use in Waste Heat Recovery Application


HFO-1336mzz(E) is a novel, non-flammable, low global warming potential (GWP) working fluid which can be used in waste heat recovery applications such as high temperature heat pumps (HTHP) and Organic Rankine Cycle (ORC). The working fluid’s performance in HTHP applications will be explored further. HFO-1336mzz(E) has a GWP of 18, a boiling point of 7.5oC (45.5oF) and a critical temperature of 137.7 oC (279.9oF). It has a zero Ozone Depletion Potential (ODP) and favorable toxicity profile based on testing to date. It remains chemically stable in glass sealed tube tests in the presence of commonly seen metals with temperatures up to 250oC for 7 days. It has also shown good compatibility with many plastics and elastomers commonly encountered in equipment presently used with these types of working fluids. HFO-1336mzz(E) is a viable solution enabling both HTHP and ORC technology platforms to recover heat from various sources and reduce fossil fuel dependencies.
