排烟防火阀联动控制消防风机的措施探讨

Discussion on Measures for Linkage Control of Firefighting Fan by Combination Fire and Smoke Damper

针对GB55036-2022 《消防设施通用规范》第11.1.5条、第11.3.5条,关于任一排烟阀或排烟口开启后,应联动启动排烟风机、补风机,任一排烟防火阀自行关闭后,应联锁关闭相应排烟风机、补风机的规定,结合暖通专业对同一排烟系统服务多个防烟分区的实际工艺要求,分析排烟风机、补风机的联动控制信号优先级,通过调整消防联动控制系统中排烟系统控制逻辑,修改排烟风机、补风机的控制电路,提出一种切实可行且满足上述规范要求的控制措施。

In accordance with Article 11.1.5 and Article 11.3.5 of General Code for Fire Protection Facilities(GB 55036-2022)"After any smoke damper or smoke vent opens,the smoke exhaust fan and supplementary fan shall be interlocked and started.After any combination fire and smoke damper closes itself,the corresponding smoke exhaust fan and supplementary fan shall be interlocked and closed",based on the actual process requirements of the HVAC profession for the same smoke exhaust system to serve multiple smoke bays,this paper analyzes the priority of linkage control signals for smoke exhaust fans and supplementary fans,modifies the control circuit of the smoke exhaust fan and supplementary fan by adjusting the control logic of the smoke exhaust system in the automatic control system for fire protection,and proposes a practical and feasible control measure that meets the requirements of the above specification.
