Fluids and parameters optimization for the organic Rankine cycles (ORCs) used in exhaust heat recovery of Internal Combustion Engine (ICE)

▸ We proposed an organic Rankine cycle recovering Internal Combustion Engine exhaust heat. ▸ We established techno-economically model and did analysis based on 20 working fluids. ▸ System performance express better at high evaporating pressure. ▸ R141b, R123 and R245fa present the highest thermal efficiency ηth and Pnet values. ▸ R141b, R123 and R245fa express the lowest electricity production cost Epc and A/Wnet values.
