| 摘 要： | 安装太阳能烟囱后的建筑具有效果优良、节能环保的自然通风系统。室内通风口高度是太阳能烟囱建筑性能的关键参数之一。提出通过改变太阳能烟囱建筑室内通风口高度位置,使太阳能烟囱既可用于建筑的日常自然通风,也能实现室内火灾场景下的自然排烟。利用缩比例实验台研究了不同室内通风口高度对太阳能烟囱建筑自然通风与自然排烟效果的影响,发现自然通风和自然排烟效果随通风口高度增加呈现先增大后减小的趋势,且最佳室内通风口高度位于窗户上檐位置附近。研究结果对太阳能烟囱建筑的建筑结构关键参数设计具有指导意义。

| Abstract: | Solar chimney in a building can be used as an excellent and energy-saving natural ventilation system. Inlet height is one of the key parameters for the performance of natural ventilation. A set of experiments were carried out to study the optimum inlet height for building with a solar chimney, which can be used for both natural ventilation and smoke exhaust. In this study, the optimum inlet height of solar chimney building was found as 0.6 m for the tested building model. Moreover, it is suggested that the optimum inlet height is related to the height of window. |
