Research For Water System Optimization On Water-saving And Energy-saving Technology

With the rapid development of social urbanization, the situation of the lacking in global water and other non-renewable energy becomes more and more serious. The consumption of water system in buildings plays a more and more important role in the total water consumption, which appeared increasing tendency. There are large amount of water and energy consumption in the process of water supply, and this trend is particularly strong in water system of high-rise building. In order to reduce utilization of global resource, and make full use of limited resources, the whole societies all should concentrate on to the realization of water conservation and energy-saving in water system of buildings. The improve of Water-supply system can make the development of water conservation and energy-saving better.In view of the development and requirements for the water supply system at home and abroad, many countries have been doing hundreds of the productive researches about energy-saving and water conservation, and committed to the development of new technology, but now, the problem has not yet been fully solved. Especially, in our country, the development is slowly than other countries because of restrictions of technical conditions. Therefore, the research about the water-saving and energy-saving technology of water-supply system has the vital significance.According to the current situation of resource utilization, this article discusses the exiting fruits of relevant research, analyses the the problems to be solved. Owing to these, the article mainly does the following research.Based on research of regional differences and energy resources, the paper applys analytic hierarchy process (AHP) to analyse the superior or inferior choice to the mode of water-supply system, which be integrated with the comprehensive requirement about resources and economic demand.The result under different conditions provides the reference for the design and refining of water-supply system with energy-saving and water conservation. It makes relevant recommendations of economic and environmental evaluation. According to the practical application, the utilization in water-supply system of existing mode have been analyzed and discussed.Secondly, by investigation about the condition of domestic water using and sanitation equipment, the paper analyses the relationship of water pressure and comfort level, then looks for reasons of the phenomenon of overpressure and give out the methods to resolve the problems in the buildings. By the measured of data analysis, the paper attempts to use decompression device to resolve the problems of overpressure. Then, according to the study of pipes usrd in water-supply system, the paper discusses special characteristics with emphasis on analysing the impact of pipe-using on energy consumption, and analyses the difference in collecting database by market research, searching for the optimal choise.Finally, the paper makes the optimized allocation, combining economic actors, and gices suggestion about the application conditions.In all, based on the study of architectural water conservation and energy-saving technology, this paper explores optimal allocation and evaluation of the research of water-supply system and offers theory support for the design of water-supply system. The paper also put forward some reference opinions to existing technical and the essential purpose of studies achieve the goal of saving water and energy.
