Numerical analysis of the effect of the evaporator inlet-outlet position on the PV-T performance

The increase in global energy consumption and carbon dioxide emissions the interest renewable sources. Solar is at forefront of sources, decrease cell efficiency due to various reasons during operation an obstacle this technology. Increasing temperature photovoltaic cells causes a efficiency. Control crucial terms both prolonging economic life increasing system. effect evaporator inlet outlet position fluid on heat transfer known, but was not examined studies carried out PV-T (photovoltaic–thermal) In current study, system parameters COP (coefficient performance) values cooled by forced air circulation were investigated CFD (computational dynamics) analysis. analyzes single array for three different flow rates (0.0125 kg/s, 0.0250 0.0500 kg/s) nine inlet-outlet positions (CC, CL, CR, RC, RL, RR, LC, LL, LR), constant radiation 1000 W/m^2. It determined that there total difference over 20% overall 25% between best worst positions. highest thermal obtained RR condition, electrical LR condition long-term, can be achieved with LC design. study also calculated CL condition.
