摘    要:研究人员活动对室内CO2浓度变化的影响。通过测试不同工况下室内的CO2浓度,分析人员活动的CO2发生量以及在无新风的情况下人员吸烟引起的CO2浓度的变化,为确定新风量提供依据;提出在不同的新风量下CO2浓度随时间变化的计算方法。实验研究表明:在无新风的房间中,由人员产生的CO2浓度呈线性增长,人员的CO2发生量与性别和体质有关;在可接受的水平下,CO2浓度对人体心率和血压的影响不大;1支香烟释放的CO2量达0.221 L;理论推导的室内CO2浓度和新风量的关系与实测结果一致。

Abstract:

The CO2 concentration by human and human activities was investigated. Measurements of the CO2 concentration were carried out under different test conditions. The CO2 generating rates by human and human activities were described, and the CO2 concentration change caused by smoking in the chamber without fresh air. The CO2 concentration change with time by different fresh air volumes can also be calculated. The results shows that in the chamber without fresh air, the CO2 concentration shows a linear growth trend, and CO2 generating rate of human is relevant to gender and physique; At an acceptable level, CO2 concentration has little effect on human heart rate and blood pressure; CO2 generating volume that a cigarette emits is up to 0.221 L; relationships between fresh air volume and CO2 concentration are deduced and tested, and they are correspondent with each other.
