摘要
罗列民用建筑中两种较常见的事故通风机工作状态,通过分析其设置的目的和功能作用,推演在事故发生之后事故通风机启动之前各系统或设备的工作流程,考虑可燃气体探测报警系统对此的影响。结合规范标准的相关规定得出:事故通风机供电负荷等级宜等同于所服务场所的供电负荷等级的结论。
The working conditions of two types of emergency ventilators commonly used in civil buildings are listed,their purposes and functions are analyzed,the working process of each system or equipment of emergency ventilators after emergency is deduced,the impact of combustible gas detection and alarm system on such working process is taken into consideration,and conclusions are drawn according to relevant specifications and standards:the classification of power supply load of emergency ventilator should be equal to that of the workplace.
