CO2 自动灭火系统按灭火剂的贮存方式分为高压和低压两种。在我国 ,高压 CO2 灭火系统技术经验成熟 ,工程应用多。低压系统是一项基于高压系统灭火原理发展起来的灭火设施。随着近年来我国低温应用技术的发展 ,低压 CO2 自动灭火设备已经完全国产化。相关规范的修订 ,也为它的 CO2 automatic fire extinguishing system according to the method of storage of fire extinguishing agent is divided into two kinds of high pressure and low pressure. In our country, high-pressure CO2 fire extinguishing system has mature technical experience and many engineering applications. Low-pressure system is a high-pressure fire extinguishing system developed based on the principle of fire-fighting facilities. With the development of low-temperature application technology in China in recent years, low-pressure CO2 automatic fire extinguishing equipment has been fully localized. The revision of the relevant norms, but also for it
