光伏光热墙体结构优化模拟研究OA
Simulation Study on Optimization of Photovoltaic/Thermal Wall Structure
提出4种光伏光热墙体,针对夏季工况,对4种光伏光热墙体的出口温度、空气得热量、光伏板表面温度进行模拟.各模型均由玻璃盖板、光伏板、空气通道、砖墙组成,模型1、2的光伏板紧贴玻璃盖板内侧,模型3、4的光伏板置于空气通道中间,模型2、4在砖墙一侧增设相变材料层.在较小的进口风速下,模型3能得到较高的空气出口温度及较高的空气得热量.模型3光伏板表面温度低于模型1、2,仅高于模型4,有利于提高光电转换效率.模型3的综合性能最佳.
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.
