高层建筑地下汽车库机械通风与排烟系统选用方案探讨

Mechanical Ventilation and Smoke Exhaust System for Underground Garage in High-Rise

根据最新的汽车库设计规范 ,对地下汽车库通风排烟的几种可行方式进行了比较 ,考虑节能和通风排烟的需求 ,提出用双速风机方案满足高峰和非高峰时的排风要求 ,并采用适当的控制转换兼用于机械排烟 。

Based on the new design criterion of underground garage, several feasible approaches of ventilation and smoke exhaust in underground garage were discussed and compared. Considering both energy-saving and the requirement of the ventilation and smoke exhaust, an option of double speed fans with a proper control system is feasible in meeting both peak and off-peak ventilation demand and this can also serve for smoke exhaust purpose.
