采用DeST-h软件分析了伊朗马什哈德地区居住建筑PVC板对建筑冷负荷的影响,并利用计算流体力学软件模拟分析了夏季建筑室内的自然通风情况,以确定室内风速.建筑室内风速的模拟结果表明,室内大部分区域是舒适的.在天花板和PVC板之间有无空气层存在的情况下,建筑顶层房间冷负荷分别减少10.5%和6.5%,说明空气层的存在有利于建筑降低冷负荷.然而,空气层厚度的增加对建筑冷负荷降低的影响并不明显.这种在天花板和PVC板之间增加空气层的策略对发展可持续性建筑十分有益.
DeST-h software was used to analyze the impact of building PVC slab on building cooling load in Iran's Mashhad area and the use of computational fluid dynamics software to simulate the natural ventilation in summer building to determine the indoor wind speed. The simulation results show that most of the indoor area is comfortable.When there is no air layer between the ceiling and the PVC board, the cooling load on the top floor of the building is reduced by 10.5% and 6.5% respectively, indicating that the existence of air layer is beneficial to the construction reduction However, the effect of increased air layer thickness on the reduction of building cooling load is insignificant, and this strategy of adding an air layer between the ceiling and PVC sheet is very beneficial for the development of sustainable buildings.
