在理论分析的基础上，利用CFD软件对自然通风作用下室内甲醛浓度的分布进行数值模拟。结果表明：利用自然通风可以减小室内甲醛的含量，通过比较卧室床放置在不同位置时的甲醛浓度分布和速度分布，得出了床在靠近门一侧时，最舒适并最有利于人体的健康。并模拟了这一方案时整个房间的流场，得到在x、y、z三个平面上的速度分布和甲醛浓度分布规律。

This paper, on the basis of theoretical analysis, uses CFD software to simulate the distribution of indoor formaldehyde concentration under the action of nature ventilation. The results showed that nature ventilation can be used to reduce the content of formaldehyde indoor. By comparing the formaldehyde concentration distribution and the velocity distribution, I found that it is the most comfortable and healthy to our body when putting the bed near the door. Besides, this paper simulated the flow field of the whole room in this situation, and obtained the velocity distribution rules and formaldehyde concentration distribution rules in x, y, z three planes.
