Performance comparison of the solar-driven supercritical organic Rankine cycle coupled with the vapour-compression refrigeration cycle

Abstract In this study, a parametric analysis was performed of supercritical organic Rankine cycle driven by solar parabolic trough collectors (PTCs) coupled with vapour-compression refrigeration simultaneously for cooling and power production. Thermal efficiency, exergy destruction the coefficient performance cogeneration system were considered to be parameters. A computer program developed in engineering equation-solver software analysis. Influences PTC design parameters (solar irradiation, solar-beam incidence angle velocity heat-transfer fluid absorber tube), turbine inlet pressure, condenser evaporator temperature on discussed. Furthermore, also compared without PTCs. It concluded that it necessary PTCs carefully order achieve better performance. The highest values thermal efficiency 92.9%, 51.13% 1437 kW, respectively, at 0.95 kW/m2 irradiation based working R227ea, but found 2.278 basis R134a. obtained from results accounted 76.32% total overall well considering
