自遮挡对壁挂式太阳能热水器影响模拟研究

高层住宅建筑中生活热水的能耗在建筑能耗中占有不可忽略的份额。目前,国内阳台壁挂式太阳能的应用有效的解决了住宅中的生活热水需求,但阳台壁挂式太阳能在高层住宅的安装使用中易受到建筑自身凸出部位的日照影响。本文通过Ecotect软件模拟,研究自遮挡对太阳能集热器年辐射量的影响,得出相关数据,为壁挂式太阳能热水器的设计和安装提供有益的指导。

Simulation Study of the Impact of Self-occlusion on Wall-mounted Solar Water Heaters

In the high-rise residence building, energy consumption domestic hot water occupies a non-negligible share of energy consumption in buildings. At present, applications of the domestic balcony wall-mounted solar water heaters offer effective solution to the residential need for hot water, but the installation and use of the balcony wall-mounted solar in high-rise residential building, is vulnerable to the inlfuence of the convex area the building itself. This paper, through Ecotect software simulation, studies the inlfuence of annual solar radiation for self-occlusion, and obtains relevant data for providing useful guidance for design and installation of balcony wall-mounted solar water heaters.
