| 摘 要： | 通过建立一模型房间，从室内空气温度分布、PPD、悬浮颗粒分布及CO2浓度几方面模拟研究了置换通风条件下室内空气品质。结果显示置换通风条件下的IAQ完全能满足相关规范规定，达到人体对健康的要求。小微粒有很好的跟随性，大微粒在重力作用下下沉到地面，CO2的浓度随高度的增加而增大，呼吸区的空气清新。

| Abstract: | From the aspect of temperature diffuse? PPD? aerosol distribution and CO2 concentration, the IAQ of a room with displacement ventilation by constructing a model of room are simulated and studied. The result shows IAQ under displacement ventilation meets the need of correlative code. Small particles follow the ventilation air flow while larger particles may settle. The concentration of CO2 increases with the height from floor, then the air of breathing area is very freshness. |
