Analysis of Solar Absorption Chiller driven by CuO Nanofluid-based PV- Thermal Solar collectors (PVT)

A numerical model based upon the energy conversion equations and heat transfer mechanisms of magnetized nanofluids taking place during PV-Thermal solar collector and absorption system, PV cell and the heat transfer fluid flowing in thermal tubes welded in the back of the PV panel and heat exchangers of the absorption system. is presented". This permitted the prediction of the electrical power output of the PV panel, thermal energy generated, and the characteristics of the waterbased nanofluids in terms of solar radiation, different nanofluids, and other system geometry parameters." The presented model compared fairly with experimental data with reasonable discrepancy. Radiation higher solar radiations have a significant impact on heat transfer fluid flow rates; however, low solar radiations increase the nanofluid-based CuO heat transfer flow rates over the water-based ones. Also, it has been shown that the higher the concentration of the magnetized nanofluid CuO, the higher the generator's thermal energy input compared to the heat transfer fluid-based water and the coefficient of performance of the absorption system. Finally, the model results in question are compared fairly with available experimental data.
