| 摘 要： | 新风量不足,呼吸产生的二氧化碳可造成教室内CO_2浓度严重超标,影响学生学习,降低课堂教学效果。以人呼出的CO_2作为示踪气体,测定研究教室有人和无人情况下教室内CO_2浓度变化,对教室新风量进行计算,其结果:室内CO_2排放条件不同,相应方程计算所得新风量基本一致,用忽略室外CO_2本底浓度的新风量计算公式,结果有约17%的误差。开启门窗产生对流,可保障教室内空气的新鲜。

| Abstract: | Classroom is the location with high human density.The high concentration of carbon dioxide and deficiency of air change flow will affect the student study and depress effectiveness of lecturing course.The air change flows were calculated by using relative formulae under the conditions with or without the students in the classroom.The results were credible,and there was approximate 17% of relative error if the background concentration of outside CO_2 was ignored in the calculation formulae of air change flow. |
