| 摘 要： | 根据房间通风效率，计算了常见的混合式通风系统的污染物稳定浓度，定量分析了影响稳定浓度的因素，如通风效率、预处理设备的效率、回风率等。认为就给定系统而言，提高通风效率特别是相对效率、提高送风量、设置空气预处理设备是降低室内污染物浓度、降低新风量的有效措施。

Analysis of factors influencing pollutant concentration in a ventilated room |
| |
| Abstract: | Based on the ventilation efficiency, calculates the steady concentration of pullutant in a comprehensive ventilating system. Analyses quantitatively the factors that affect contaminant concentration in the room, such as ventilation efficiency, efficiency of air filters, and return air ratio. Considers that for a given system, to increase ventilation efficiency especially relative ventilation efficiency, to increase supply air and to set air filters are effective means for reducing contaminant concentration in the room and fresh air requirement. |

| Keywords: | ventilation efficiency steady concentration air distribution |
