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。
Thermal and electrical energy is a form of energy necessary for construction, so hot water and photovoltaic systems in solar buildings should be considered at the same time. In order to increase the proportion of solar energy in the energy structure of buildings, in particular in multi-level and high-rise buildings, the installation of concentrators should not be limited to the roof but must be extended to the façade. Different forms of energy are mainly used in different seasons, so the light collector's posture and location should be significantly different. This paper analyzes the factors that affect the concentrator attitude from the radiation conditions, the supply and demand synchronization and the sensitivity to the change of the shielding and combination surfaces, and discusses the design examples.
