Problem analysis on fire smoke exhaust system design and fan selection
摘要：
分析了暖通空调工程设计中常见的排烟系统风管水力计算以及排烟风机的选型问题，认为排烟风机的选型对风管系统水力工况稳定性有影响，设计时可与设备厂商配合选型，选择合适的排烟风机。提出了排烟风机的选型对于风管系统水力工况稳定性的影响，以及排烟系统设计中应予以关注并提供给设备厂商的相关参数。
Abstract：
Analyses the common problems of duct hydraulic calculation and the selection of smoke exhaust fan type of smoke exhaust system in the design of HVAC engineering. Considers that the selection of smoke exhaust fan type has impact on the stability of hydraulic working condition of air duct system. The fan manufacturer may be asked to select the appropriate exhaust fan together when designing the smoke exhaust system. Provides the impact of the type selection of smoke exhaust fan on the hydraulic condition stability of air duct system, as well as the related parameters which should be concerned during the design of smoke exhaust system and provided to manufacturers.
Keywords:smoke exhaust rate, resistance calculation, fan type selection, fan performance curve, fan working point
