摘要: Abstract An experimental study of thermal characteristics a novel two-inlet air-based open-loop building integrated photovoltaic/thermal (BIPV/T) system using full-scale solar simulator is presented. Experimental prototypes one-inlet and BIPV/T systems were constructed for conducting comparative experiments. Variations are also investigated including employing opaque mono-crystalline silicon photovoltaic (PV) panels semi-transparent PV panels. results demonstrate that an equivalent with frameless can increase the efficiency by 5% compared to conventional system, achieves 7.6% higher due absorption some radiation at bottom surface in cavity. Also, design easily implemented does not add significant cost. Detailed air temperature measurements reveal mixing warm outlet from first section cool ambient drawn second inlet contributes improved performance system. Based on network model data, correlations developed convective heat transfer coefficients two sections. These necessary further analysis development multiple inlets.
