房屋建筑和通风对农户室内空气质量的影响

室内空气质量受复杂交互因子的影响,它是多种影响因素和过程相互作用的结果,因此清晰辨别理解各因素对室内空气质量的影响和作用方式,是制定正确的改善空气质量措施的基础。本文针对农村室内空气质量污染的特点,对影响农村室内空气质量的主要因素房屋建筑与通风进行研究和分析。在开门关窗、开门开窗两种通风方式进行室内CO浓度测试,开门开窗工况下,室内CO浓度超标时间较开门关窗工况下减少了8 m in,而且CO浓度峰值也由开门关窗工况下的17.3m g/m3降为开门开窗工况下的13.9 m g/m3。对CO浓度和空气换气率进行相关性分析,发现两者之间有较强的负相关关系。

Impact of construction and ventilation on indoor air quality

Indoor air quality is influenced by complex factors,which is the interactive result of multiple factors and processes.So a clear understanding of the factors' effect on indoor air quality and the role is the base to develop the right measures of improving air quality.The article focuses on research and analysis of housing construction and ventilation-one of the main factors of rural indoor air quality pollution.First test indoor CO concentration by two ventilation means.The study shows that under the condition of opening windows and door the period of door indoor CO concentrations exceeding the normal values reduced eight minutes,and the peak of CO concentration falls from 17.3 mg/m~3 to the 13.9 mg/m~3 compared with the condition of opening door only.According to the relevance analysis of CO Concentration and air ventilation rates,There is strong negative correlation between them.
