中庭对建筑空调冷负荷的影响
Influence of atrium on air conditioning cooling load of buildings
摘要:
以各层有回廊与中庭相通的建筑为研究对象,采用多区域模型的方法对建筑内部进行了区域划分,应用EnergyPlus软件对不同建筑朝向和不同中庭高度建筑模型的空调冷负荷进行了逐时模拟,分析了中庭的存在对建筑总冷负荷和各层冷负荷的影响。结果表明,各层冷负荷随楼层升高而增大,顶部两层增加幅度最大;中庭的存在仅对各层回廊区域的空调冷负荷有影响,较远的走廊区域所受影响可以忽略;东西朝向中庭建筑的总冷负荷大于南北朝向中庭建筑。
Abstract:
Taking a building with the atrium connected to the cloister of each storey as a study object, adopts the multizone model method to partition the whole building and analyses the influence of the atrium on the total cooling load of the building and the cooling load of each storey through simulating hourly cooling load of buildings with different orientations and different atrium heights with Energy Plus software. The results show that the cooling load of each storey increases with the increase of stories, especially at the top two stories; the influence of atrium only occurs in the cloister of each storey, the farther corridor would not be affected; the total cooling load of the east-west orientated building with an atrium is larger than that of the north-south orientated building.
