Design Research Of The Solar Water Heating Technology Of Rural Residential Buildings In Cold Area

The problem of building energy consumption is a very serious in China, with the accelerating process of urbanization, many cities, especially small towns have also accelerated the pace of construction, so in winter the solar hot water system to provide heating is a effective means of reducing the building energy consumption. In recent years,in the developed countries of European and American,the solar hot water heating has been researched in a lot of aspects.In China, although the solar hot water system has also been applied to a certain extent, the extent and scope of application is far from the foreign levels, which affected the development of solar water heating technology. Toward the above problems, the thesis mainly designs and analyzes the rural new Solar heating system in cold region, the main research work is divided into six parts:(1) the first chapter,mainly by introducing the topic and research background, etc., illustrates the framework of this research and the main content, and analyzes solar hot water system status and problems, leads the subject of this paper;(2) The second chapter,by the way of visiting field, testing analysis, questionnaire survey, toward the heating issues of rural residential buildings in cold regions, carry on the actual investigation, summarize, analyze induction, proposed the suitable method of rural residential solar heating design in cold areas, lay the foundation for the research of the solar hot water heating technology and the design of solar heating systems.(3) The third chapter, toward the basic knowledge and choosing principles of the solar water heating systems carrys on a brief description, and the ends of different heating system was analyzed; contrast two sets of advantages and poor of the mainly residential solar hot water heating system in the current village, and analyzes the feasibility of low temperature radiant floor heating system in cold regions, proposes to improve the design of solar hot water heating system. (4) The fourth chapter, is the part of designing system, completed the design, the analysis of principles,structure and model calculations of the solar low-temperature radiant floor heating system, the system model by simulation tests, masters the working conditions and efficiency of system, the application Heating is provided in the engineering practice and research which based on the data.(5) The fifth chapter is part of engineering practice, it introduced the whole process of engineering practice of the solar water heating,in Yizi town of Linyi City, Shandong seismic rural house, including the optimizing selection of system, the test analysis of the relevant parameters and the scheduling efficiency assessment of saving energy construction, combined with engineering practice to install structural practices into a variety of applications finally, summarized a set of solar heating systems which is suitable for villages in cold areas, provided a reference design way for the engineering designer.(6) The sixth chapter is the analysis and evaluation part,mainly analyzes the technical issues of the solar collector system,related to the economic evaluation program of the proposed system, apply the integrated method with energy prices, integrated with building model for the economy evaluation of indicators of several solar heating systems, and proposed the significance of the project.Theory with practice, the theory through the synthesis of the cold climate and geographical situation of energy consumption, makes full use of solar energy, searchs for heating methods and technology strategy which is suitable with the rural house building, proposing the new heating system of solar low-temperature radiant floor, and tests and analyzes with an engineering example as a verification, which summarizes elements and design methods of the solar heating system of the characteristics rural house for cold regions.Improving the status heating effect of rural resident,significantly enhances the indoor comfort of rural resident for the low-income rural areas to provide a economy reasonable heating way, reaches the saving energy requirements of the new rural construction,achieve the sustainable development of resource, environment and society...
