Simulation Study on Optimization of Photovoltaic/Thermal Wall Structure
Four kinds of photovoltaic/thermal walls are proposed,and the outlet temperature,air heat gain and surface temperature of photovoltaic panels of four photovoltaic/thermal walls are simulated for the summer working conditions.Each model is composed of glass cover,photovoltaic panel,air passage and brick wall.The photovoltaic panels of models 1 and 2 are tightly attached to the inside of the glass cover,the photovoltaic panels of models 3 and 4 are placed in the middle of the air passage,and the phase change materi-al layer is added on one side of the brick wall in mod-els 2 and 4.At a smaller inlet wind speed,model 3 can obtain a higher air outlet tem-perature and a higher air heat gain.The surface tem-perature of the photovoltaic panels in model 3 is lower than that of models 1 and 2,and only higher than that of model 4,which is conducive to improving the photoe-lectric conversion efficiency.Model 3 has the best o-verall performance.
