热水与光伏系统集光器的姿态区别

Difference of Stance between the Collectors of Water Heating and Photovoltaic System

热能和电能是建筑必需的能量形式,因此在太阳能建筑中热水和光伏系统应同时考虑。为了扩大太阳能在建筑能源结构,特别是多层和高层建筑能源结构中的比例,集光器的安装部位也不应局限于屋顶, 而必须向立面拓展。不同形式的能量其主要使用的季节也不同,因此集光器的姿态和部位应有明显区别。该文拟从辐射条件、供需同步性及对遮挡及组合面变化的敏感性方面对影响集光器姿态的因素进行分析,并结合设计实例进行探讨。

Heat and electricity are necessary energy forms in building. Therefore, the water heating system and photovoltaic system should be taken into account at the same time in solar building. In order to enlarge the proportion of solar energy in energy structure of building, especially in that of multiplayer and skyscraper, the collector should not be fixed within roof only, but develop to front and side faces of building. The main using season of the energy with different form is distinguishing. Therefore, the stance and position of collectors should have obvious difference. In this paper, we are going to analyze the effect factors of collector from the aspects of radiation condition, in-phase of supply and demand and sensitivity of shelter and variation of combinatorial plane, then discuss them with some design examples.
