摘要： Disclosed is a method for producing heating in a heat pump that involves extracting heat from a working fluid comprising E-HFO-1336mzz, in a heat exchanger, thereby producing a cooled working fluid. Also disclosed is a method for producing heating in a heat pump wherein heat is exchanged between at least two cascade stages. Also disclosed is a heat pump apparatus including a working fluid heater, compressor, working fluid cooler and expansion device and said apparatus contains a working fluid comprising E-HFO-1336mzz. Also disclosed is a method for replacing CFC-114, HFC-245fa, HFC-236fa, HCFC-124, HFC-134a, CFC-12 working fluid in a heat pump designed for said working fluid that involves providing a replacement working fluid comprising E-HFO-1336mzz. Also disclosed is a composition containing (i) a working fluid consisting essentially of E-HFO-1336mzz; and (ii) a stabilizer; or (iii) a lubricant; or both (ii) and (iii).
