Energy Saving And Optimization Of High-rise Building Water Supply System

When we for floor construction design building,large span,complex technology of water supply,on all project phases of high-level water supply have more demand.In the case of high building height,water supply is accompanied by the constant expansion of energy consumption,energy efficient use of water is becoming particularly crucial the water supply.aimed at exploring the problems of energy consumption existing in the water supply system,the domestic water supply system for high-rise buildings,the energy saving and optimization are studied in this paper.Full text in the various energy demand for high-level water supply rates for parsing,illuminates the advantage of water supply in order to reduce energy consumption in different regions of the world,analyzed the energy consumption in different regions in comparison,on the basis of given points appropriate number of regional water supply scheme.There are many ways to supply water in high-rise buildings.Each way has its own advantages and disadvantages and scope of application.According to different characteristics of high-rise buildings,selects the most suitable water characteristics of the water supply mode,it is the main problem in the design of the water supply of high-rise building.In this paper,the author access to the domestic and foreign reference literature of the Three scale analytic hierarchy process(AHP)of high-rise building water supply system optimization analysis,high-rise building water supply manner also adopt this method choice to be more accurate and the selection of water supply way,and good results have been achieved in engineering practice.Taking the Hefei city of the high-rise building as an example,according to the water law of analysis results by the Three scale AHP method choose the way of water supply,and the water supply system of optimization,combined with economic analysis,it is concluded that the optimum water supply scheme.Full text for recently obtained widely application of VVVF(varial frequency and variable velocity)constant pressure water supply system energy saving aspects to carry out the detailed exploration.This paper introduces the operation principle of variable frequency pump,throy application in energy saving and data calculation.using the advantage of variable velocity pump to the greatest degree of play at the same time,this paper compared the optimization matching of variable frequency pump and under the different matching of the maximum extent of the energy saving effect of the program,discussing the implementation of the program.
