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

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.
