Theoretical analysis and experimental study of energy conservation for pressure-superposed water supply in buildings

摘要

Due to the need of water supply energy conservation,pressure-superposed water supply energy conservation effect was analyzed firstly.Secondly,the pressure-superposed water supply energy conservation monitoring device,which using the water pressure of municipal pipe network,was developed based on PLC,inverter,touch screen and GPRS.Finally,the energy conservation effect was tested by use of the developed device,and the results of experiment were consistent with theoretical analysis.Furthermore,it was expected that the obtained results could provide a theoretical basis and technical support for water supply energy conservation.
