Energy and Exergy Study of a Nanofluid-based Solar System Integrated with a Quadruple Effect Absorption Cycle and Thermoelectric Generator

The exploitation of nanofluids is the most noteworthy way to make better rate heat transfer in solar collectors. Moreover, recently utilizing thermoelectric generators are widely studied direct conversion into electricity. objective present study deal with a novel multigeneration system that includes nanofluid-based parabolic trough collector integrated quadruple effect absorption refrigeration cycle (cooling), generator (power), PEM electrolyzer (hydrogen), vapor and domestic water heater. A parametric accomplished consider significant parameters such as volume concentration nanoparticles, radiation, system’s load, strong solution concentration, TEG’s figure merit on overall performance, hydrogen production rate, cooling COP useful energy obtained by collector. It observed power generated 18.78 kW exergy efficiency 82.21% 80.48%, respectively. Furthermore, results showed highest destruction occurs at 4461 kW. COPs chiller discovered be 1.527 0.936, By increasing nanoparticles amount increases while TEG decreased. capacity increased an increase VHTG load decreased solution.
