西安某高校教室室内热环境与空气品质测试及分析

Study on the Indoor Thermal Environment and Air Quality of a Classroom Xi'an University During Heating Period

在供暖季节测试了西安某高校在不同的室外空气质量情况下上课和自习教室内的温度、相对湿度和PM10、PM2.5、CO_2等指标的含量。分析结果表明,室外空气质量对室内的热环境影响不大,但对室内PM10、PM2.5和CO_2浓度影响非常大。建议在雾霾天气上课时可适当在课间开门进行通风来减少室内CO_2浓度并且有条件的话可在教室安装空气净化器。

This paper tested the indoor temperature,relative humidity and the concentration of PM2.5、PM10 andCO2indifferent circumstances of the outdoor air quality class and self-study classroom of a university in xi'an during heating period.Analysis results showed that the influence of outdoor air quality on the thermal environment of the classroom is not high,but it has a high influence on indoor PM2.5、PM10 andCO2 concentration.It is suggest to open the door during the hours of the haze weather to reduce the indoor CO2 concentration and to install the air purifier in the classroom
