| description | This study aims to use a cooling technology for photovoltaic-thermal (PVT) collectors more effective in terms of cooling and enhancing the thermal efficiency of the system in general. This was done by using bi-fluid modes (air and Al2O3–water nanofluid), which are characterized by being more effective in terms of cooling and enhancing the overall thermal efficiency of the system. To achieve this, aluminum dual exchangers were incorporated with an aluminum back surface of the monocrystalline photovoltaic panels. The cooling was achieved using the Al2O3–water nanofluid at various concentrations of 0.0, 0.2, 0.4, 0.6, 0.8, and 1 % with a steady flow of water at 0.01 kg/s and at a simultaneous airflow rate. Also, the effect of different levels of Al2O3 nanoparticle concentrations (0.0, 0.2, 0.4, 0.6, 0.8, and 1 %) was studied to identify the optimal concentration of Al2O3–water nanofluids that achieves the highest rates of cooling and thermal efficiency of PVT collectors. The 3D numerical model was validated using the experimental published data. The results showed that the total thermal efficiency of PVT modules with the bi-fluid modes is equal to 46.63 %, 48.96 %, 52.39 %, 54.13 %, 59.43 %, and 63.28 %, for Al2O3–water nanofluids concentrations of 0.0, 0.2, 0.4, 0.6, 0.8, and 1 %, respectively. The PV module with the bi-fluid modes (air and Al2O3–water nanofluids with 1 % concentration) at a steady flow of water at 0.01 kg/s is the best design for effective cooling of PV panels, which can contribute to more sustainable and energy-efficient solar energy conversion systems. |
