This growing demand has to be met without increasing (or preferably, by decreasing) the environmental impact. One of the ways to do so is the use of existing low-temperature heat sources for producing electricity, such as using power plants based on the organic Rankine cycle (ORC) . In ORC power plants, instead of the traditional steam, the vapor of organic materials (with low boiling points) is used to turn heat to work and subsequently to electricity. These units are usually less efficient than steam-based plants; therefore, they should be optimized to be technically and economically feasible. The selection of working fluid for a given heat source is crucial; a particular working fluid might be suitable to harvest energy from a 90 ? geothermal well but would show disappointing performance for well with a 80 ? head temperature. The ORC working fluid for a given heat source is usually selected from a handful of existing fluids by trial-and-error methods; in this collection, we demonstrate a more systematic method based on physical and chemical criteria. 606 $aHistory of engineering and technology$2bicssc 610 $aadiabatic expansion 610 $abiomass 610 $acis-butene 610 $afluid mixtures 610 $aheat exchange load of condenser 610 $aHFO-1234ze(E) 610 $ahydrocarbons 610 $aideal-gas heat capacity 610 $aisentropic expansion 610 $amolecular degree of freedom 610 $anet work output 610 $aoptimization 610 $aORC 610 $aORC working fluids 610 $aorganic Rankine cycle 610 $aR432A 610 $aR436B 610 $aR441A 610 $aRankine cycle 610 $asaturation properties 610 $aselection method 610 $asingle screw expander 610 $asingle-screw expander 610 $aT-s diagram 610 $aT-s diagram 610 $atemperature-entropy saturation curve 610 $athermal efficiency 610 $athermodynamic analysis 610 $avapor-liquid two-phase expansion 610 $avolumetric expander 610 $awet and dry fluids 610 $awet zeotropic mixture 610 $aworking fluid 610 $aworking fluid classification 615 7$aHistory of engineering and technology 700 $aImre$b Attila R$4edt$01279061 702 $aImre$b Attila R$4oth 906 $aBOOK 912 $a9910557127803321 996 $aWorking Fluid Selection for Organic Rankine Cycle and Other Related Cycles$93014501 997 $aUNINA
