摘　　要：建立了3种不同形式的光伏组件安装方式的一维非稳态理论模型。通过MATLAB建模仿真,比较了在不同布置方式下,光伏组件对车顶传热量的影响。使用与普通车顶比对的方法,分析了光伏车顶的夏季遮阳与冬季保温效果。结果表明:夏季使用带通风流道的光伏车顶布置方案较佳;冬季使用封闭流道的光伏车顶布置方式较佳。The one-dimensional unsteady state theoretical models of three different installation modes of photovoltaic modules are established.The influence of photovoltaic modules on roof heat transfer under different arrangement modes is compared by simulating.The solar shading effect in summer and thermal insulation effect in winter of photovoltaic roof are analyzed by comparing with that of ordinary roof.The results show that the roof layout scheme with ventilated flow channel is better in summer.In winter,the photovoltaic roof layout with closed flow channel is better.
