双向通风窗通风对室内空气品质的改善

摘要

In this paper,using the indoor CO2 concentration as an indicator,a multi-zone airflow network model of CONTAM was applied to study the indoor air quality under the infiltration and dual-airflow window ventilation conditions of a residential building in Harbin.The results demonstrated that infiltration could not achieve acceptable indoor air quality, while dual-airflow window ventilation could improve the indoor environment effectively.%本文以室内CO2浓度为评价指标,应用多区模型模拟软件CONTAM分析比较了哈尔滨某住宅建筑内自然渗风和双向通风窗通风作用下的室内空气品质.结果显示,应用双向通风窗之前,室内的CO2浓度变化很大,最高达5400 mg/m3左右;应用双向通风窗之后,室内的CO2浓度基本稳定在l 440 mg/m3以下,表明空气品质得到了明显改善.
