在实际工程设计中,经常会遇到面积与体积超出GB 50370-2005《气体灭火系统设计规范》中要求的超大防护区。以超大监控大厅采用备压式七氟丙烷气体灭火系统设计为例,对超大防护区气体灭火系统的选型、设计思路、解决方案进行了分析与探讨。
In the actual engineering design, often encounter large area and volume exceeding GB 50370-2005 “Gas Fire Extinguishing System Design Code,” the requirements of oversized protective areas. Taking the design of large-scale monitoring hall as backup gas-type heptafluoropropane gas fire extinguishing system as an example, the selection, design method and solution of gas fire extinguishing system in super-large protective area are analyzed and discussed.
