Exergoeconomic and Exergetic Sustainability Analysis of a Combined Dual-Pressure Organic Rankine Cycle and Vapor Compression Refrigeration Cycle

In this paper, an exergoeconomic and exergetic sustainability analysis of a dual-pressure organic Rankine cycle (ORC) vapor compression refrigeration (VCRC) driven by waste heat is performed for power generation cooling production. addition, the most suitable fluid couple among thirty-five different pairs was investigated proposed combined system. The results indicate that highest energy utilization factor, exergy efficiency, system coefficient performance, net are calculated R123-R141b pair. terms indicators, best performance obtained combination. minimum unit electricity cost shortest payback period as 0.0664 $/kWh 2.5 years, respectively, R123-R290 component with destruction boiler, 21.67%. result parametric showed thermodynamic parameters increase increment ORC’s boiling temperature. increasing temperature, environmental effect factor decreases, while index increases. Additionally, temperature increases, total production decrease. It suggested to use created thermodynamic, analysis.
