以武汉中心办公楼层的公共卫生间为例,采用Fluent软件,通过改变补风形式、送风口位置、换气次数及排风口位置等参数,模拟了不同工况下的氨气浓度。结果表明:顶部送风比卫生间门洞渗风和侧面送风效果好;在顶部送风形式下,最佳换气次数为10h~(-1);排风口底边缘应距离污染源释放面0.2m。
Taking the public toilet in the office floor of Wuhan Center as an example, the Fluent software was used to simulate the ammonia concentration under different working conditions by changing the parameters such as the wind supply form, the position of the air supply port, the number of air changes, and the position of the air outlet. The results show that the top air supply is more effective than the toilet door hole in infiltration and side air supply; in the top air supply form, the optimal air change frequency is 10h~(-1); the bottom edge of the air outlet should be 0.2m from the pollution source release surface. .
