Design data: per schedule attached. 2. 采用一套分配系统进行保护. One set of equipment is to be provided. 3. 保护区为独立封闭区间. Protected area is totally enclosed. 4. 保护区平时环境温度与自然环境温度相同. Environmental condition of the protected area is same as surrounding area. 5. 保护区均设置通风设备. Ventilation system is provided in protected area. 6. HFC-227ea灭火系统瓶站设置在保护区内. FM200 container is located within protected area. 7. 瓶组间的楼板应能承载储瓶组的重量. Floor structural design shall be capable to withstand the weight of the FM200 container equipment. 三. 设计 DESIGN： 1. 设计依据DESIGN COMPLIANCE 1) To comply to GB50307-2005《气体灭火系统设计规范》Regulation for fire fighting gas system design； 2) To comply to GB50263-97《气体灭火系统施工及验收规范》Regulation for fire fighting gas system installation and inspection/acceptance； 2. 灭火方式FIRE EXTINGUISHING METHOD: 本设计采用全淹没式灭火系统,在规定的时间内,喷射一定浓度的七氟丙烷灭火剂,并使其均匀地充满整个保护区,此时能将在其区域里任一部位发生的火灾扑灭. Fire extinguishing is by total flooding method. Within specified time limit, FM200 gas shall be discharged to the concentration as designed for total flooding and able to extinguish the fire in any location within the protected area. 3. 灭火系统的控制方式为自动、电气手动、机械手动三种.在有人工作或值班时,采用电气手动控制；在无人的情况下,采用自动方式. 自动、七氟丙烷（HFC-227ea）灭火系统设计说明－中英文对照 2 / 8 2 手动控制方式的转换,在灭火控制盘上实现（在保护区的门外设置手动控制盒, 手动控制盒内设有紧急停...
