The photoelectric conversion efficiency of photovoltaic thermal (PVT) systems is a key concern in solar energy research. widespread use continuous nanofluid cooling PVT/NPCM (Nano-Enhanced Phase Change Material) leads to heightened consumption. In order improve the systems, two-dimensional transient heat transfer numerical model established analyze system with intermittent flow cooling. Corresponding govern equations boundary conditions are proposed, and numerically solved by using finite element method. Simulation results compared experimental data, showing deviation less than 7%. findings indicate that reduces consumption required drive 2220 liters over 7-hour period. Furthermore, under conditions, average electrical stands at approximately 19.7%. Notably, employing closely aligns those cooling, exhibiting maximum merely 0.0348%. Additionally, emerges as favorable choice radiation intensities surpasses 1000W/m2, enabling significant reduction overall while maintaining commendable performance.

Critical Analysis of Enhanced Photovoltaic Thermal Systems: A Comparative Experimental Study of Pcm, Teg, and Nanofluid Applications

Опубликована: Янв. 1, 2024

Phase change materials (PCM), thermoelectric generators (TEG), and nanofluids are popular methods investigated for improving conventional photovoltaic thermal (PVT) systems, particularly in warm climates where high temperatures negatively impact (PV) power output energy efficiency. This experimental study evaluated the effects of 32 °C melting point PCM TEG integration on PVT units, as well 42 nanofluid incorporation concentrated (CPVT) units. Technical, exergetic, economic performance were compared using a small-scale module. Low-cost commercially available used to construct all Industrial metal waste was introduced enhance conductivity paraffin wax salt hydrate PCMs. The results indicated that applying PCMs, porous media, concentrator plates increased generation, potentially offsetting their higher initial cost achieving an approximately $0.135/kWh. However, implementation remained uneconomical, leading 15-35% increase cost. water-based CPVT unit, enhanced with copper fins, demonstrated best technical performance, electrical, thermal, exergy efficiencies 15.5%, 37.4%, 16.7%, respectively, more than 20% reduction cell temperature. also revealed severe structural changes caused by corrosion metallic hydrated PCMs could alter 30%, impacting heat storage capacity. Conversely, incorporating chips non-hydrated facilitated reaching state within 30-60 minutes.
