The Theoretical And Experimental Research Of New Hot Water Supply System In Cold Regions Based On Coupleed With The Heating System

This paper for people on the growing demand for living hot water, and currently buildings by the local water supply exists unreasonable use of energy, high energy prices, not continuous heating and other problems, we put forward a new centralized hot water supply system which is suitable for cold regions and based on heating system.On the basis of detailed research to various forms of hot water supply, designed a new water supply system, in which the hot water in the centralization heating system is the hot medium, and each household as a unit; Developed the major equipment of single family heating set-- floating helix pan pipe namely hot type heat exchange set; Through theoretical analysis and experimental study, showing that the new hot water supply system can meet the heating requirements; Gives the law of interaction between indoor shared system and the heating net working condition changed; The use of dynamic cost of annual value of law as the objective function, including eight hot water systems and the new system, select the fuel price to sensitivity analysis on the program, proving the new hot water supply system is reasonable of economic; Using the fuzzy comprehensive evaluation method to environmental analysis the discharge of pollutants from every program heat, give the environmental impact assessment of new hot water supply system.The main innovation lies in that the indoor hot water supply system and heating system are connected by heating set installed in each household and central heating pipe network, it supplies heating and hot water to indoor through the heating set using heat provided by the outdoor heating network. This system has the function of heating and hot water supply stimulatingly, hot computation , hot accommodating and controlling, decreasing the pressure in pipe and equipment, saving the exalted and expensive energy, being easy to examine and repair, et..The results show that the new hot water supply system full-featured, economy, energy saving, environmental protection, it must be ideal plan of residential buildings centralization hot water supply system. Research results can be put into residential construction quickly, it receives social benefits of increasing the building's using function and improving people's living standards, what's more, it forms huge economic benefits of household heating device production and promoting the residential commercial supply.
