Solar Water Heating System On Cold-formed Thin-walled Steel Residential Buildings Integrated Application

Currently, The development of a new type of structural system faster was cold-formed thin-walled steel residential buildings at home and abroad, As one of the typical representative of the energy saving building, Be used for all kinds of industrial and civil buildings because of its characteristics was component of the industrialized production and short construction period. But less research for solar water heating system on cold-formed thin-walled steel residential buildings integrated in the country, So the study of contributes to promoting the development of industrialization of the cold-formed thin-walled steel residential buildings in the field. The thesis is divided into four parts:The first part describes the background and significance of the solar water heating system on cold-formed thin-walled steel residential buildings integrated. Analysis of the structure and research status of the building at home and abroad,and development status of solar energy technology, The research contents and ideas of this paper are determined. In the second part, the problems of domestic solar water heater are analyzed,The specific installation form of the solar collector bracket in the building and Pipeline setting is different Because of the difference between the roof structure and the wall structure from the traditional architectural form.Therefore, this chapter focuses on the study of the problem is the installation of heat collector and pipeline of solar water heating system on cold-formed thin-walled steel residential buildings integrated design. The design of self tapping bolt to achieve the node on the roof connection with the heat collector, and add a column or a beam on the south wall to achieve the node on the wall connection with the heat collector.The third part of the study of different forms of Architecture from solar water heating system on cold-formed thin-walled steel residential buildings integrated design. Based on the meteorological conditions in Hefei area,The modeling was established for two Single family residential to using PBECA building energy-saving software, Calculation of the optimal direction and the dip angle and the optimal layout area of the solar collector, At the same time, The optimization design of the water tank and auxiliary heating equipment were compared, The optimal selection scheme was obtained because of by comparing the solar fraction and the Static payback period as well as the economic benefits. Final calculation results was solar water heating system to get the heat for the year and evaluation of the energy efficiency of the whole system, To provide a certain reference for residential users.Finally, the analysis of the architectural planning to cold-formed thin-walled steel residential buildings, Mainly aimed at the new rural construction and pension real estate and the geological disaster prone areas. The fourth part of the design of solar water heating system were combined,Analysis of the selection and installation of heat storage tank and heating end and auxiliary heat source device for solar heating system,The proposed protection scheme corresponding to overheating and antifreezing of heating system.To present the main problems and promotion measures of the solar heating system.
