Investigation of Different Working Fluid Effects on Exergy Analysis for Organic Rankine Cycle (ORC)

In this study, energy and exergy analyses are performed for an Organic Rankine Cycle in a local powerplant that is located southern of Turkey. The Organic Rankine Cycle was used for low temperature heatsource as heat recovery process with various organic working fluids. The examined system consists of anevaporator, a turbine, a condenser, a pump and a generator as components. The evaluation is carried outusing two different working fluids for each component of the system. The main purpose of this study is tomodel the ORC cycle for performance optimization in terms of the usage of two different working fluidswith relevant temperature ranges. HFE7100 and FC72 working fluids are selected as performanceparameters in order to show the effect of the working fluids on the system performance of the OrganicRankine Cycle.
