“…An investigation was done on the performance of ORC through 88 ml/r displacements of scroll expander and its influences on isentropic efficiency decrement from 0.72 to 0.41% [67], [68]. It can be observed that R123, R245fa working fluids have a high frequency to get a power maximum of 3.75 kW [69], [70]. Similarly, a simulated model of screw expander by considering leakage, heat transfer, and friction loss was developed [71].…”

<span>Exergy, one of the handed-down energy conservation techniques, which can obtain from thermodynamic laws (first and second), will disclose the work presented within the system, the amount of irreversibility as well as what are the possible ways to reduce inefficiencies in the system. This discourse mainly highlighted various techniques and possible methods for efficiency improvement in the organic Rankine cycle (ORC). That means mainly concentrated on following key parameters like the selection of working fluid, suitable expander, the different heat source of an evaporator, and modifications in heat exchanger based on the application of ORC system through an exergy approach for better performance, decrease energy losses, and destruction rate. This review can help to pontificate for better-summarized results that were done before and suggested some ideas for how to select an optimized parameter for better efficiency and to decrease the destruction rate in the ORC system. </span>
