摘　　要：家装板材会造成卧室内甲醛污染。运用仿真模拟软件Airpak为平台,建立卧室模型,对卧室内的气流组织、空气龄和甲醛浓度分布分别进行模拟分析,并给出甲醛污染控制措施。研究结果表明,增加机械通风能够有效降低室内甲醛浓度,而且上送风下回风方式的净化效果要优于下送风上回风方式。增加净化器只能作为辅助手段改善局部区域甲醛污染。因此,可通过改变卧室内布局,利用自然通风来改善室内甲醛污染。Home decoration board may cause formaldehyde pollution in the bedroom.Using the simulation software Airpak as the platform,the bedroom model was established.The air distribution,air age and formaldehyde concentration distribution in the bedroom were simulated and analyzed,and the formaldehyde pollution control measures were given.The results show that increasing mechanical ventilation can effectively reduce indoor formaldehyde concentration,and the purification effect of up supply and down return air is better than that of down supply and up return air.Increasing the purifier can only be used as an auxiliary means to improve the formaldehyde pollution in local areas.The indoor formaldehyde pollution can be improved by changing the layout of the bedroom and using natural ventilation.
