论文摘要
在一项大型研究中，对德国北部下萨克森州所有类型学校的教室的空气质量进行了监测。用于空气质量监控的新型传感器仪器在50所学校和日间托儿所的329间客房中安装。每个传感器仪器记录二氧化碳CO $ _2 $，声音水平，温度和湿度的数据。所有收集的数据均通过WiFi连接到数据库进行监视和进一步的统计评估。这项研究首次对六个多月的学校的空气质量状况和学校处理进行了详细的调查。这种情况的特征是教室区域种类繁多，而且体积结合了非常多样化的空气通风可能性。为了控制教室中通过气溶胶传播病毒的传播，迫切需要根据信号建议的空气质量监测，并根据信号建议进行高依从性。
The air quality in classrooms across all types of schools in Lower Saxony in the north of Germany has been monitored during June to December 2021 in a large study. Novel sensor instruments for air quality monitoring were wall mounted in 329 rooms in 50 schools and day nurseries. Each sensor instrument records data for carbon dioxide CO$_2$, sound level, temperature, and humidity. All collected data are transmitted for monitoring and further statistical evaluation by WiFi connection to the database. This study provides for the first time a detailed survey of the air quality situation and handling in schools during more than six months. The situation can be characterized by large variety in classroom area and volume combined with very diverse air ventilation possibilities. To control virus transmission via aerosol in classrooms an individual monitoring of air quality combined with high compliance for ventilation according to the signaled recommendation is urgently required.
