Abstract：
Analyses the development tendency of variable frequency energy saving controlling technology for the central chilled water plant, and points out that the whole control method is the development direction of chilled water plant control technology. Presents the full variable frequency control system of a chilled water plant at a museum in Wuhan, and tests the energy efficiency of the chilled water plant when operating under small load. The result shows that the energy saving efficiency is obvious.
