Use of (2E)-1,1,1,4,5,5,5-heptafluoro-4-(trifluoromethyl)pent-2-ene in high temperature heat pumps

Abstract:

A method for producing heating in a high temperature heat pump having a heat exchanger is provided. The method comprises extracting heat from a working fluid, thereby producing a cooled working fluid wherein said working fluid comprises (2E)-1,1,1,4,5,5,5-heptafluoro-4-(trifluoromethyl)pent-2-ene ("HFO-153-10mzzy"). Also, a high temperature heat pump apparatus is provided containing a working fluid comprising HFO-153-10mzzy. Also a composition is provided comprising (i) a working fluid consisting essentially of HFO-153-10mzzy; and (ii) a stabilizer to prevent degradation at temperatures of 55.degree. C. or above, or (iii) a lubricant suitable for use at 55.degree. C. or above, or both (ii) and (iii).
