Research On Central And Heating Household Energy-saving Control Technology

Energy is the cornerstone of development of human, under the current energy shortage condition, I t is imperative to save energy, develop new energy and effectively make use of energy. Building energy consumption is a significant part of energy consumption, reducing building energy consumption has practical significance, However, citizens demand better and better residential quality. Demand of high energy consuming equipment is growing, such as air-condition, floorheating. It is imperative to make citizens live comfortable based on saving energy. As the intermediate link of heating, Central heating plays an important role in saving energy and improving residential quality. Whereas individual user is the terminal link, not only satisfy the heating need but also implement saving energy own important significance. Central heating control and separate heating control respectively control saving energy on heating process and terminal, which is 2 hot points of building energy saving research.Household heat measurement is the base of household inner temperature controlling. This paper firstly introduce different types of building heating pipe network and measurement and regulation equipment of household inner temperature controlling.Secondly, according to heating theory, construct the mathematical model of inner temperature. According to the principle of smith predictor, design improved PID controller which could control inner temperature. With MATLAB simulate smith prediction controlling system and fuzzy PID inner temperature controlling system with smith predictor then compare, analysis them.City central heating system mainly includes heating station, hot water pipe network, heat exchange station, user and some other part. As the intermediate segment whichlink heating station and user, heating exchange effect of heat exchange station is important, which is a important segment of implementing controlling energy. This paper adopt Yangting garden of Weihai city as the project case, design heating monitor system of heating exchange station. Hardware of this system is SIEMENS S7-300 PLC,programme with STEP7. Configuration function of monitor PC is achieved by KingView, exchange data exchanging and transforming is achieved with Internet, reach the design goal, implement the intelligence controlling of heating system of heating exchange station.
