由于可用空间的限制和不断增加的设计防火要求，需要优化风机选择，这就要求设备制造商设计适合正常通风和高温应急烟雾管理环境的设备。更高温度额定值、循环负载和变频驱动的收敛导致设计和应用考虑变得更加复杂。本文探讨了与地下交通应用中使用的紧急烟雾管理和通风机相关的应用问题和由此产生的设计考虑。引文:伊利诺伊州芝加哥ASHRAE会议论文

The need to optimize fan selections for limitations in available space and ever increasing design fire requirements challenge equipment manufacturers to design equipment suitable for both normal ventilation and the high temperature emergency smoke management environment. The convergence of higher temperature ratings, cyclic loading and variable frequency drives results in design and application considerations becoming much more complex. This paper explores the application issues and resultant design considerations related to emergency smoke management and ventilation fans used inunderground transit applications.
