Energy and exergy analysis of Regenerative organic Rankine cycle with different organic working fluids
This paper shows the theoretical and numerical framework for basic and regenerative organic Rankine cycles. Exergetic analyses of basic and regenerative organic Rankine cycles at various evaporator pressure (EVP) with various working fluids are conducted in order to convert low-grade heat sources waste energy to useful work. The fluids selected for this analysis are R113, R123, R236ea, R245fa, and R141b. The results show that the regenerative organic Rankine cycle (RORC) gives better energy efficiency, exergy efficiency, network output, and the lowest total system exergy loss. R113 is the optimum working fluid for RORC at EVP of 2MPa to 3MPa. It is also concluded based on results by increasing the EVP the energy efficiency, exergy efficiency, network output increases, and total system exergy loss decrease
