Use of (2e)-1,1,1,4,5,5,5-heptafluoro-4-(trifluoromethyl)pent-2-ene in power cycles

Abstract

A method is provided for converting heat from a heat source to mechanical energy. The method comprises heating a working fluid using heat supplied from the heat source; and expanding the heated working fluid to lower pressure of the working fluid and generating mechanical energy as the pressure of the working fluid is lowered. The method is characterized by using a working fluid comprising (2E)-1,1,1,4,5,5,5-heptafluoro-4-(trifluoromethyl)pent-2-ene (HFO-153-10mzzy). Also provided is a power cycle apparatus. The apparatus is characterized by containing a working fluid comprising HFO-153-10mzzy.
