          摘要:

          对上海市某中学教室进行了实测,结果表明目前该教室缺乏有效的机械通风手段,导致通风不足、CO2浓度易超标、不能有效防护室外颗粒物污染等问题。通过方案比选,提出了新风净化方案,并实施了工程改造。改造后的实测结果显示,新风净化技术可有效降低该教室室内PM2.5和CO2浓度水平,提高室内空气质量。

          Abstract:

          The field measurement of a middle school classroom in Shanghai shows that there lacks effective mechanical ventilation, resulting in insufficient ventilation, high CO2 concentration exceeding the limit of standard and ineffective outdoor particulate pollution prevention. Through the comparison of the schemes, proposes a scheme of outdoor air purification system (OAPS) and implements an engineering transformation. The results show that the OAPS can effectively reduce the indoor PM2.5 and CO2 concentration level in the classroom and improve the IAQ.
