What is the working fluid for organic Rankine cycle?
Hydrofluoroolefin (HFO) working fluids from Opteon™ deliver superior performance for organic Rankine cycles. With a substantially lower GWP than legacy working fluids, Opteon™ solutions are an optimal solution for waste heat recovery applications.
What is the working fluid in the Rankine cycle?
Unlike the commonly used Rankine Cycles, which operate on the water as the working fluid (so-called as the steam power cycles), the ORCs operate on organic fluids.

What organic fluids are used in Rankine cycle?
Toluene is identified as the organic fluid with the maximum thermal efficiency compared to R123 and R245fa [23]. Benzene and Methanol exhibit higher efficiency and lower fluid flow demand than other fluids [24] .
How does the organic Rankine cycle work?
The ORC turbogenerator uses medium-to-high-temperature thermal oil to preheat and vaporize a suitable organic working fluid in the evaporator (4>5). The organic fluid vapor rotates the turbine (5>6), which is directly coupled to the electric generator, resulting in clean, reliable electric power.
