Experiment of Energy Conservation for Building Water Supply Based on Residual Pressure of Municipal Pipe Network

Due to the need of water supply energy conservation in buildings,based on PLC,inverter,touch screen and GPRS,the energy-saving monitoring device of pressure-superposed water supply is technically developed,which uses the water pressure of municipal pipe network.At the aspects of application,the energy conservation effect is tested by using the developed device,and it is expected that the obtained results can provide a technical support for water supply energy conservation in buildings.
