A Low GWP Working Fluid for Transcritical Rankine Power Cycles
This paper briefly reviews basic properties of HFO-1336mzz-Z (cis-CF3CH=CHCF3), reports new data on the compatibility of HFO-1336mzz-Z with plastic and elastomeric materials and evaluates HFO-1336mzz-Z as a potential working fluid for Organic Rankine Cycles (ORC) driven by, relatively, high temperature heat (expander inlet at 175-250 oC). HFO-1336mzz-Z has a favorable toxicity profile (based on testing to date), it is non-flammable at 60 oC and 100 oC and offers a very low GWP of 2.
