What is the working fluid for organic Rankine?
The Organic Rankine cycle allows power recovery of waste heat streams that are too low in temperature to be cost- effectively converted into power by conventional steam cycles. The use of organic fluids, such as refrigerants, enables efficient and cost-effective power recovery of waste heat streams.
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?
The choice of the organic fluids was based on previous reports [4, [62] [63][64], where the best efficiencies for the organic Rankine cycles operated in similar conditions to those of the present study were obtained with benzene, toluene, and cyclohexane.
What is the best working fluid for ORC?
For the heat carrier inlet temperatures of 280 °C and 350 °C are considered. Rankings based on the thermal efficiency of the ORC and on the heat capacity flow rates of the heat carrier as well as on the volume and the heat flow rates show cyclopentane to be the best working fluid for all cases studied.
