华龙一号电气厂房冷水系统设计优化研究

Design optimization of chilled water system of Hualong No.1 electric plant

介绍了华龙一号电气厂房冷水(WEC)系统的设计功能。从水冷机组与风冷机组启停切换、外部灾害防护2个方面进行分析,提出了水冷机组与风冷机组手动切换改自动切换、增设高位电动隔离阀的优化方案,以较小的代价提升了WEC系统的自动化水平,提高了应对外部灾害的防护能力。

Presents the design function of the chilled water(WEC)system of Hualong No.1 electric plant.Analyses from the two aspects of start-stop switching between water-cooled and air-cooled units,and protection against external disasters.Proposes an optimization scheme for manual switching to automatic switching between water-cooled and air-cooled units,and the addition of high-position electric isolation valves,improving the automation level of the WEC system at a small cost and the protection against external disasters.
