不同气流组织下对卧室甲醛浓度影响模拟分析

Simulation Effect of Formaldehyde Concentration Bedroom on Different Air

在空调房间内,气流组织在消除室内污染方面起着关键作用。文章运用CFD软件来对卧室中4种常见的气流组织形式进行模拟,得到房间内的气流分布及甲醛浓度分布,分析气流的速度场对甲醛浓度场的影响。结果表明,在相同的室内条件下,同侧上送下回、异侧上送下回、顶送下回和下送顶回4种典型送风形式中异侧上供下回的送风方式最佳,能有效影响甲醛浓度分布,为休息中的人们提供一个较为洁净和舒适的睡眠环境。

Airflow plays a key role in eliminating indoor pollution in air-conditioned rooms.In this paper,CFD software is used to simulate four common airflow patterns in the bedroom,to obtain the distribution of airflow and formaldehyde concentration,and to analyze the influence of the air velocity field on the formaldehyde concentration field.The results showed that under the same indoor conditions,same side up supply and down return,different side up supply and down return,top supply and down return,and down supply and top return.and different side up supply and down return on the bottom were the best,which could effectively affect the distribution of formaldehyde concentration and provide a relatively clean and comfortable sleeping environment for people at rest.
