广东省充电车库的通风和排烟系统设计的思考

Consideration on Ventilation and Smoke Exhaust System Design of Charging Garage in Guangdong Province

通过对常规单速单风机系统、双速单风机系统在充电车库火灾排烟工况、平时通风工况的风管设计阻力进行计算对比,同时结合风机设备选型,发现在充电车库排烟排风系统设计中,传统的单速风机系统、双速风机系统会对车库噪声、风机运行能耗和设备运行安全产生不利影响,并提出单速双风机系统更符合充电车库火灾排烟和平时排风两种工况下的设计要求。

Calculates and compares the design resistance of the air duct of the conventional single speed single fan system and the dual speed single fan system under the fire smoke exhaust working condition and the normal ventilation working condition of the charging garage.At the same time,combined with the selection of fan equipment,it is found that in the design of the smoke exhaust system of the charg‐ing garage,the traditional single speed fan system and the dual speed fan system will have adverse effects on the garage noise,fan opera‐tion energy consumption and equipment operation safety.It is proposed that the single speed double fan system is more in line with the de‐sign requirements of the charging garage under fire smoke exhaust and normal air exhaust conditions.
