What is the working fluid for organic Rankine?
Alkanes, aromates and linear siloxanes are considered as working fluids for high-temperature organic Rankine cycles (ORCs).
What are the steps in the organic Rankine cycle?
The working principle of the organic Rankine cycle is the same as that of the Rankine cycle: the working fluid is pumped to a boiler where it is evaporated, passed through an expansion device (turbine, screw, scroll, or other expander), and then through a condenser heat exchanger where it is finally re-condensed.

New Working Fluids for Organic Rankine Cycles
With a substantially lower GWP than legacy working fluids, Opteon™ solutions are an optimal solution for waste heat recovery applications. Opteon™ MZ working fluid is the best choice for organic Rankine cycle systems.
What is the fluid in the Rankine cycle?
The organic Rankine cycle (ORC) uses an organic fluid such as n-pentane or toluene in place of water and steam. This allows use of lower-temperature heat sources, such as solar ponds, which typically operate at around 70 –90 °C.
The pressure-enthalpy and the temperature- entropy diagrams of the simple organic Rankine cycle with R245fa as the working fluid are shown in Figures 2 and.
