Conventional steam power cycles have their limitations on recovering low grade waste heat, therefore other alternatives are required in these cases. Organic Rankine Cycle (ORC) is suitable for power generation based on various heat sources including solar, geothermal, biomass or waste heat. ORC working fluids can be characterized as wet, dry or isentropic. The aim of this paper is to give a method to find novel dry or isentropic working fluids based on simple physical properties, like degree of freedom and isochoric heat capacity.
