Study On Optimizing The Saving Water And Energy Of Residential Water Supply System For Life

The residential community domestic water have supply large quantities of waterand uneven water supply service area is wide, complex pipelines and long distance,head loss, and require high water and big water pressure, so that the residential domesticwater supply make the larger the energy consumption. With the residential waterconsumption in the proportion of the total urban water consumption increasing, thatmake the saving water and energy of the water supply system in the residentialcommunity can’t be ignored. So, the paper make the residential life water system as theobject of study, and have optimization studies on the water and energy saving from theresidential water consumption and the way energy consumption analysis.Firstly, the paper analyzes the composition of residential water consumption, andmakes the optimization of each component of water ration. Based on the waterconsumption per capita annual statistical value of all provinces and cities in2003~2010, and the water ration of all provinces and cities affiliate public construction rulesor try out, Using two average method to optimize the residential community life andaffiliate public buildings water ration, get the water quota suggested value of domesticwater and residential community affiliate public buildings. Based on the climate of theclimate, and the street flushing demand and greening water ration of the national civilbuilding design technology measures (2009), get the water quota suggested value of theStreet flushing demand and greening water in Each climate zone, and give three kindswater saving measures: Using water-saving appliances and development communitywater systems and Strengthen pipeline leak detection, ensure that residential communityunder the premise of normal water save water.By analyzing the water way of the residential life and energy consumption, getlower seam and multiple layer and high-rise and ultrahigh-rise residential community.For optimizing election about the residential water way of life, not only consider theenergy consumption, but the three factors are taken together, and use analytic hierarchyprocess mathematical modeling, make it be suited to different types of residential lifewater-supply modes. The paper only optimize election the high-rise residential waterway of life, get the water-supplying mode of overlying power frequency and highcistern is the best, and be checked by the example. Lastly, the paper focus on the overlying kind of water system about high-riseresidential community for optimization researching, give the calculation formula aboutthe set elevation and adjustable volume of the steady flow can, and the applicable scopeof the water pump head and flow. Focus on the optimized selection of pump, beanalyzed and checked with the example...
