根据英国BCB管道冻结服务公司报道:英国某机场在更换空调系统时成功地施行了管道冻结技术,即将两根长度为17.78厘米、直径为10.16厘米的支管,用液氮形成的冰塞将其堵住,这样既节约了更换费用又节省了时间。原先,在盖特威克的英国民航局工程技术人员认为这是一项一般性的排水工程,但却面临排水设备至少要全部关闭两天的问题,而且整个系统恢复到令人满意的运行状态还要更长的时间。这
According to British BCB pipeline freezing service company reported: British airfield in the replacement of air-conditioning system successfully implemented a pipeline freezing technology, the two will be the length of 17.78 cm and a diameter of 10.16 cm of the branch, the formation of liquid nitrogen ice jam plug Live, which saves both replacement costs and saves time.
