摘要
空气龄是评价室内空气品质的指标之一,本文利用CO2示踪气体得出了常用的6种气流组织形式下标准气室中各测点处的浓度衰减曲线,并计算出各测点的空气龄。实验可重复性较好,测得的空气龄反映了标准气室各点空气的新鲜程度,描述了不同气流组织形式通风效率的高低,揭示了室内空气的流动形态,也给空调房间气流组织形式的合理选择提供了依据。
The air age is one of the indexes of the indoor air quality. By using CO2 trace gas, the concentration decay curves are obtained for six air distributions in a standard testing room. The air age is calculated from the test data. The experiments have a good repeatability. The freshness of air in the ventilated space, the capability of ventilation in the different air distribution, the flow form and how to organize air flow reasonably for the air-conditioning room are reflected by measured air age.
