住宅建筑新风系统对室内空气质量和舒适性影响的测试与评价

Measurement and Evaluation of the Influence of Fresh Air System on Indoor Air Quality and Comfort in Residential Buildings

为了研究新风系统对住宅建筑室内空气质量和舒适性的影响,论文以某住宅楼房间为测试样本,通过现场测试,得到两种工况下室内CO_(2)浓度及空气分布特性指标(ADPI)的变化情况。研究表明新风系统对室内空气品质具有良好的改善作用,在论文模拟的实验条件下,2h内室内CO_(2)浓度提升值小于400ppm,远低于无新风系统作用状态;合理的新风系统设计有助于提高室内环境的舒适性,ADPI值由13.30%提高到46.67%。本文研究对于本地区新风系统的设计使用具有一定的参考意义。

In order to study the influence of fresh air system on indoor air quality and comfort of residential buildings,this paper takes a residential building room as a test sample,through field test,the variation of indoor CO_(2) concentration and air distribution characteristic index(ADPI)under two conditions were obtained.The study shows that the fresh air system has a good effect on improving indoor air quality.Under the simulated experimental conditions,the increase value of indoor CO_(2) concentration in 2 hours is less than 400 ppm,which is much lower than that without fresh air system The reasonable design of fresh air system helps to improve the comfort of indoor environment,and the ADPI value increases from 13.30% to 46.67%.The research in this paper has certain reference significance for the design and application of fresh air system in this area.
