摘要:加强通风换气、提高换气频次,用室外清洁空气来稀释室内空气污染物,使其浓度降低,是改善室内空气品质,提高舒适性最经济有效地途径。对比了关窗关空调,关窗开空调和开窗关空调三种状态时居民主卧的甲醛浓度,探讨了利用通风换气频次和时间改善室内空气品质的效果和策略,并提出相应的方法。研究结果表明:每天关闭门窗后至少要4个小时开窗通风一次,每次开窗时间不少于15分钟,可有效改善室内空气品质和热环境。

The Effect of Natural Ventilation on Removing Formaldehyde from Indoor Air
Abstract:Strengthen natural ventilation and increasing the frequency is effective approach to control formaldehyde concentration. Residents can utilize the clean air outdoor to dilute the indoor air, reduce the pollutants concentration, and then improve the indoor air quality. The concentrations of formaldehyde in three indications which included closing the door and windows and air conditioning equipment, closing the door and windows but open air conditioning equipment and open the door and windows were compared. The approach to improve the indoor environment by the application of natural ventilation was discussed. The appropriate design method was concluded and highlighted. The results show that ventilation at least four hours once after closing the door and widows, less than 15 minutes each time, which can effectively improve indoor air quality and thermal environment.
