摘要
提出了一种新型百叶式光伏窗,建立物理模型并利用Ecotect及Radiance软件交互协作,就百叶式光伏窗的不同结构对室内自然采光质量的影响进行数值模拟。研究表明,光伏百叶片间距、透明度及窗墙比的增加,对于室内采光质量均有提升,其中间距、窗墙比的增加对提升效果较为显著;随着倾角的增加,房间内满足照度要求的空间占比不断下降,并在45°后趋势减缓,自然采光系数则呈现先下降后上升的趋势,在倾角60°时最小;适宜的窗墙比与透明度可以使得房间的全自然采光时间比在90%以上,能够满足采光需求。
In this paper,a new louvered photovoltaic window was proposed.The physical model was established and the influence of different structures of the louvered window on the quality of indoor natural lighting was numerically simulated using Ecotect and Radiance.Research shows that the increase of photovoltaic blade spacing,transparency and window-wall ratio can improve the indoor lighting quality,among which the increase of photovoltaic blade spacing and window-wall ratio is more significant.With the increase of inclination Angle,the proportion of space meeting the requirements of illumination in the room decreases continuously,and the trend slows down after 45°.The natural lighting coefficient shows a trend of decreasing first and then rising,and it is the smallest when the inclination Angle is 60°.Appropriate window wall ratio and diapason can make the full natural daylighting time ratio of the room is 90%above,it can meet people’s lighting needs.
