摘　　要：如果消防管道周围温度低于0℃(如冷藏仓库、严寒隧道等),管内会出现水冻结的情况。当发生火灾时,自动喷水系统会因为无法供水而导致火灾无法及时扑灭,从而造成巨大的火灾损失。防冻措施分为防冻液技术、伴热技术和干式系统。在分析总结上述3种防冻措施前提下,提出了技术和经济评价因子,并给出了评价方法。When the temperature around the fire pipe is lower than 0℃(such as refrigerated warehouse,cold tunnel),the water in the pipe will freeze.If there is a fire,the automatic sprinkler system will be unable to put out the fire in time because of the lack of water supply,resulting in huge fire losses.Antifreezing measures are divided into antifreeze technology,heat tracing technology and dry system.This paper summarizes the above three antifreeze measures,puts forward the evaluation factors and gives the evaluation methods.
