Analysis of the Energy Efficiency of Frequency-Changing Water Supply by Secondary Pressurizing in Residence Community
In order to run the secondary pressurizing pump station in the residence community more economically, the operating principles, control methods and suit conditions of four kinds of water supply systems were introduced and they are: common circular soft started constant pressure frequency-changing system, circular soft started constant pressure frequency-changing system with little capacity pumps, high efficiency frequency-changing system within full flow area and variable flow and pressure system. The energy efficiencies of these kinds of water supply systems were analyzed with their engineering applications. The issues to be concerned in these water supply systems were also discussed.
