Research On The Water Supply Systems Of Residential Quarters

With the rapid development of our construction industry, how to save unnecessary energy becomes more and more important to the society and the engineers. Saving unnecessary power and decreasing the pollution have already teen the criterions——whether the design of a modern building is successful or not . The paper give a further discussion on the saving measures of water- supply system , especially to different choices of water-supply ways bringing different influence to the energy use ,according to the characters of using water in residential quarters .In residential quarters ,compared with the way of using pump or frequency-modulated pump simply ,the way of using pump and water tank is more economic.The secondary pollution of the water use in the daily life is a popular problem. how to prevent and harness this problem is an urge requirement .The paper ,first, starts from the reason , discuss the measures of preventing and harnessing of producing secondary pollution , then mentions some solving ways from design ,materials, management and so on.The choice of the water-supply way is related to the reliability, the investment , the expense ,the management and the effect of using of the whole water-supply system ,This paper does a detailed research on the comparison of the water-supply design and how to choose a better one . It believes that the way of designing more than one aim and the fuzzy comprehensive evaluation in fuzzy mathematics are more reasonable and practical .It offers a detailed introduction to the theories and the using way .At last , this paper discuses the working principle of frequency-modulated water supply ,the working situation of the water-supply system by frequency-modulated pump and the consumption of electricity of the frequency-modulated, water-supply way. It points out that this kind of water-supply way is not better than the combined way of using pump and water tank from the point of energy saving , management ,investment and reliability of water supply ,and the pressure is not steady.
