摘要
为改善观众区的热舒适范围,在自然通风调节下增加体育馆的室内换气次数,文中以湿热气候的广州地区为例,运用Fluent、Weather Tool等软件对抽象出的对称形态和非对称形态体育馆模型进行模拟计算.结果表明:在相同外部条件下,非对称形态更能提升室内换气次数;调整风向与非对称形态体育馆迎风面的相对关系,可使自然通风条件下更大面积观众区的热舒适范围扩大,提升湿热地区自然资源的使用效率.
In order to increase the indoor air change rate of gymnasiums and enlarge the thermal comfort zone of the spectator area under natural ventilation condition and with special consideration of the environment in Guangzhou, China, the symmetrical and unsymmetrical form models of a gymnasium are simulated with Fluent and Weather Tool. The results indicate that, in the same external condition, the unsymmetrical form is more effective in increasing the indoor air change rate of the gymnasium than the symmetrical form, and that, by adjusting the relative position between the wind direction and the windward side, the thermal comfort zone of the spectator area of the gymnasium in an unsymmetrical form can be enlarged under natural ventilation condition, thus increasing the use efficiency of natural resources in hot and humid regions.
