Abstract:

From the perspective of environmental performance and resource utilization, water mist system is superior to other fire extinguishing systems and is gradually becoming the first-choice design scheme for newly-built large and medium-sized archives in China. However, there's a substantial divergence of opinion among major engineering design companies in China regarding the number of high pressure plunger pump group in water mist system and its protection range during the detailed engineering. This article takes the design of a real archive for example, analyzes in detail the concepts of enclosure and protection partition that influence the number of high pressure plunger pump group system, and puts forward a valuable viewpoint that the enclosure shall be defined as a limited space externally enclosed or partially enclosed and internally connected or separated by non firewalls and can meet the requirements of water mist fire extinguishing, providing guidance for the design of similar engineering projects in China.
