置换新风系统室内颗粒物扩散及分布规律
|
摘要
通过对置换新风实验系统的室内各个测点的颗粒物浓度测试,得到室内各个测点的颗粒物浓度值,分析新风颗粒物的分布规律,并通过数值模拟的方法进行验证。研究表明,新风颗粒物中亚微米粒径范围的粒子对室内颗粒物浓度分布规律影响较大,且浓度分布较为均匀。颗粒物粒径在1. 0～3. 0μm范围时,粒子浓度在室内分布存在一定波动性,但总体特征还是较为平稳的。
By testing the concentration of particulate in a school laboratory we can know the concentration of particulate at each measuring point. Then analyze the distribution of fresh air particulate was and verify the conclusion by numerical simulation. The results show that the particles in the sub-micron size range of the fresh air particle have a greater effect on the distribution of indoor particulate concentration,and the concentration is well-distributed. The particle concentration indoor distribution fluctuates slightly while the particle size between 1. 0-3 μm,but viewing the situation from a whole the concentration is well-distributed.
