【英文篇名】 Comparison of biological particles distribution in different ventilated rooms 【作者中文名】 赵彬; 张昭; 李先庭; 【作者英文名】 By Zhao Bin ★; Zhang Zhao and Li Xianting★Tsinghua University; Beijing; China; 【作者单位】 清华大学; 【文献出处】 暖通空调, Hv SARS; 通风; 数值模拟; 【英文关键词】 particle; SARS; ventilation; numerical simulation; 【摘要】 针对当前严重急性呼吸综合症 (SARS :severeacuterespiratorysyndrome)肆虐这一情况 ,以性质和SARS病毒颗粒性质类似的颗粒为对象 ,采用数值方法对置换通风、混合通风以及自然风形成的穿堂风房间 ,在相同的送风量和同样的颗粒产生源情况下的颗粒分布进行了模拟和比较。为了进一步比较颗粒产生源位置的影响 ,对穿堂风情况计算了两种颗粒源位置的颗粒浓度分布。结果表明通风形式对室内生物颗粒的分布有着重要影响 ,对于文中列举的算例 ,穿堂风形式下的室内生物颗粒浓度最低 ,防御生物污染的能力最好。 【英文摘要】 To accommodate the need to analyze the movement of SARS virus, which is very important for current status, selects the particle as the similar to SARS virus particle to study. Numerically simulates and compares the particle distribution in a room with displacement ventilation, mixing ventilation cross ventilation method under the same supply air volume and particle generation rate. Furthermore, two different locations of the particle source for cross ventilation are considered. The results show that the ven...
