新型建筑光伏幕墙和外窗自然通风设计

Natural Ventilation Design of New Photovoltaic Building Walls and Windows

新型建筑光伏幕墙是在建筑外窗下面布置倾斜光伏组件,这样既能保证建筑具有较大的光伏板安装面积,又不会影响建筑正常开窗。为了保证光伏板具有良好通风的同时,尽量降低对外窗自然通风的影响,采用CFD模拟分析了在不同通风腔顶部和下部开口尺寸及窗户开启角度、尺寸等参数下,通风腔开口和外窗自然通风流量系数、外窗进风温度所受影响。

The new building photovoltaic wall＇s photovoltaic module is installed below the exterior window, so it can ensure a large installation space for the photovoltaic panels, and does not affect the normal use of window. In order to ensure that the photovoltaic plate has a good ventilation and to minimize the effects on the natural ventilation of external windows, the CFD is applied to simulate the influence of the ventilation cavity with different top and bottom opening size, the window opening angle and opening size,and other parameters on the ventilation cavity opening, windows＇ natural ventilation flow coefficient and the inlet temperature of the exterior window.
