平板太阳能集热器与建筑物屋顶的一体化结构设计

Integrated Structural Design of Flat-plate Solar Collector and Building Roof

在建筑设计阶段考虑太阳能集热器与建筑物屋顶的一体化结构设计,可以满足太阳能利用、设施维护、屋顶空间利用和建筑美学等要求。在计算出接收太阳辐射的最佳屋顶坡度的基础上,对双坡对称屋顶、双坡不对称屋顶、单坡屋顶和平屋顶等几种屋顶结构形式进行太阳能集热器安装结构的设计比较,分别分析在不同纬度地区每种屋顶结构在可利用的屋面面积、有效集热器面积和屋顶空间利用等方面的优势和劣势。为了便于太阳能集热器及其水管的安装与维护,提出了一种有维护通道的坡屋顶结构形式。

Considering the integrated structural design of solar collectors and building roof in the building design stage, it is able to satisfy the requirements of solar energy utilization, equipment mainte- nance, roof-space utilization and architectural aesthetics. On the basis of calculating the roof obliquity for best receiving solar radiation, several forms of roof structure are presented, and their advantages and disad- vantages in areas of different latitude are analyzed in roof area, effective area of solar collector and roof space utilization. To be convenient for installation and maintenance of solar collectors and their pipes, a roof structure with maintenance alleyway is presented.
