既有建筑给水系统节能改造研究

Research on Energy-saving Reconstruction of Water Supply System in Existing Buildings

建筑给水系统的运行能耗主要产生于二次加压供水、循环水加压、热水加热等环节,用水环节本身也附加有能量消耗。对既有建筑给水系统的不同能耗环节分别进行了节能、节水潜力的理论分析,介绍了各环节的节能、节水改造措施,并进行了技术评价,以期为建筑给水系统的节能改造提供借鉴。

The operation energy consumption of building water supply system is derived from the processes such as secondary boosting water supply, circulating water boosting, water heating and so on. Water consumption also requires energy consumption. The energy and water saving potential of those en- ergy consumption processes in existing building water supply system is theoretically analyzed. The energy and water saving reconstruction measures of the processes are introduced, and the technical assessment is performed with a view to provide a reference for energy saving reconstruction of building water supply system.
