【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。更多还原

【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.更多还原
