| 中文摘要: |
| 高层建筑发生火灾后，保护人员的安全是个十分重要的问题。把楼内的一定区域设计为避难区或安全区，并对该区进行正压送凤，可以防止火灾烟气进入，从而使人们免受烟气的影响。本文讨论了避难区内外压差的计算方法，指出此压差取在２５－８５Ｐａ范围内为宜，分析了外界风速、建筑物的窗户破裂及门的开启或关闭对压差产生的影响，并对间接加压方案作了探讨． |
| 英文摘要: |
| It is a significant problem to insure the safety of occupants during the fire of high-rise buildings,The refuge areas in buildings can prevent the persons not to suffer theinfluence of smoke when they entered these areas。In this paper,the pressure differencebetween refuge areas and other spaces,and the methods of indirect pressurization weredibcussed,The prebsure fluctuations due to the opening or shutting of doors,the glassbroken of windows and the effects of the outside wind are analysisd too,and suggestedsome measures should be adopted when designing the smoke control system of refuge areas |
