Performance Assessment and Working Fluid Selection for Novel Integrated Vapor Compression Cycle and Organic Rankine Cycle for Ultra Low Grade Waste Heat Recovery

This paper presents the performance assessment and working fluid selection for a novel integrated vapor compression cycle-organic Rankine cycle system (i-VCC-ORC), which recovers ultra-low-temperature waste heat rejected (50 °C) by condenser of (VCC). The analyses are carried out refrigeration capacity (heat input) 35kW along with component sizing organic (ORC). effects operational parameters on were investigated. is estimated in terms net COP, thermal efficiency exergy completely utilizing recovering VCC system. R600a-R141b COPnet (3.54) ORC (3.05%) found to be most suitable VCC-ORC pair. integration increases COP 12.5% as compared standalone Moreover, sensitivity analysis results show that there exists an optimum operating condition maximizes
