影响通风房间浓度因素的分析 【英文篇名】 Analysis of factors influencing pollutant concentration in a ventilated room 【作者中文名】 涂光备; 李景广; 【作者英文名】 By Tu Guangbei ★ and Li JingguangTianjin University; China; 【作者单位】 天津大学; 【文献出处】 暖通空调, Hv 稳定浓度; 气流组织; 【英文关键词】 ventilation efficiency; steady concentration; air distribution; 【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 【英文摘要】 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 ...
