ABSTRACT
In the current work, analytical expressions have been coded in MATLAB 9.0 linked with REFPROP 9.0, for solar-powered ORC system integrated with conventional compound parabolic concentrator using environment-friendly hexane/R1234yf zeotropic mixture to calculate hourly (8 AM to 4 PM) combined performance of solar power ORC based on experimental data. It has been observed that maximum heat gain in the collector is 5.132 × 105 W at 1 PM for the mass fraction (0.7/0.3). Moreover, maximum overall thermal efficiency 17.65% is attained at 1 PM for the mass fraction 0.3/0.7 whereas overall exergetic efficiency 49.23% is achieved at the same time for the mass fraction 0.3/0.7.
