Test and analysis of classroom air quality in northern area
摘要：
在供暖季测试了哈尔滨某高校典型教室内的温度，相对湿度和二氧化碳、一氧化碳、挥发性有机物、甲醛、可吸入颗粒物、氡的含量，并进行了室内空气质量的问卷调查。分析结果表明，主观调查和测试结果比较吻合，二氧化碳含量对教室内空气质量影响最大，合理控制教室内人员密度和加强通风可以改善教室内空气质量。
Abstract：
Tests the indoor temperature, relative humidity and the concentration of carbon dioxide, carbon monoxide, volatile organic compounds, formaldehyde, respirable particles and radon in typical classrooms of a university in Harbin during heating period, and investigates classroom air quality by questionnaires. The analysis results indicate that the subjective investigation and test results are in good accordance, that the effect of carbon dioxide concentration on classroom air quality is the largest, and that indoor air quality can be improved by reducing occupant density and enhancing indoor ventilation reasonably.
