Experimental and Numerical Investigation of a Mechanically Ventilated, Multiple Skin Facade with Between-the-Panes Venetian Blinds 带窗格间百叶窗的机械通风多层幕墙的实验和数值研究
考虑了一种机械通风、光伏集成、多表皮立面,包括上部窗格玻璃之间的威尼斯百叶窗层和下部窗格玻璃之间的光伏阵列。组合光伏和遮阳系统可以以预热新鲜空气的形式产生电能和热能,并允许调节采光。开发的数值模拟仅用于预测系统上部(威尼斯百叶窗板条周围)的空气速度、玻璃和遮阳温度。在室外试验室中,在三个盲缝翼角度(=0、45和75º)和三个风扇转速(10、20和30 Hz)下,总共设计并测试了九个实验场景。模拟预测,百叶窗和室内玻璃层的平均温度在2.3℃和5.4℃之间(4℃。 1和9.7°F),并预测空气峰值流向速度在粒子图像测速测量值的18%以内。本研究首次详细介绍了带中间窗格百叶窗的通风窗的数值模拟开发。未来的研究将侧重于推导窗格玻璃之间的对流传热关联式,并开发可集成到建筑能耗模拟软件中的简单一维模型。单位:双引文:ASHRAE交易,第116卷,第。1、奥兰多
A mechanically ventilated, photovoltaic-integrated, multiple skin facade, consisting of a between-the-panes Venetian blind layer in the upper section and a between-the-panes photovoltaic array in the lower section was considered. The combined photovoltaic and shading system can produce electricity and thermal energy in the form of preheated fresh air, and allow for adjustable daylighting. Numerical simulations were developed to predict the velocity of air and glazing and shading temperatures only in the upper section of the system (around the Venetian blind slats). A total of nine experimental scenarios were designed and tested at three blind slat angles (? = 0, 45, and 75º) and three fan speeds (10, 20, and 30 Hz) in an outdoor test room. The simulations predicted the average blind and indoor glazing layer temperatures to within 2.3 and 5.4°C (4.1 and 9.7°F), respectively, of the experiment and predicted the air peak streamwise velocities to within 18% of Particle Image Velocimetry measurements. The present study introduce, for the first time, a detailed account of numerical simulation development of ventilated windows with betweenthe- panes Venetian blinds. Future studies will focus on deriving between-the-panes convective heat transfer correlations and developing simple one-dimensional models that can be integrated into building energy simulation software.Units: Dual
