Selection of Working Fluids for Low-Temperature Waste Heat Recovery Using Organic Rankine Cycle

Abstract:

As for the industrial exhaust heat with the temperature ranging from 120°C to 200°C, 5 working fluids commonly used in organic Rankine cycle, namely R113、R123、R134a、R245fa and R600a, have been analysed from the perspective of safety, environment and economical efficiency. The results show that: R123 is of great poison, but its thermal economical efficiency is the best, especially under the condition of high temperature. The suitable ambient temperature ranges from 20-35°C. R245fa belongs to a safe and environment friendly fluid. For its best comprehensive property and wide range of ambient temperature, R245fa is very beneficial to the ORC system.
