Design Of Integrated Structure Of Solar Water Heating System And Building Roof

In today’s increasingly tense of conventional energy sources, building energy conservation has become an inevitable trend in the development of architectural design. Solar water heating systems and building integration has increasingly attracted people’s attention, and gradually become the main research in building energy efficiency. This article from the perspective of the architectural design, analysis the design for the structure of the solar building integrated, in particular compare various solar collectors on the building roof forms proposed structure suitable for rooftop solar thermal utilization in different regions, and the solar energy roof thermal form of a brief assessment.Contents of this paper are as follows:First, structural design and analysis of the solar hot water system and building integrated, characteristics of a combination of different forms of solar water heating systems and building integration.Second,layout of the collector,hot water storage tank and piping system of solar hot water systems, and combining the characteristics of the overall style, split solar water heating systems and building integrated.Third, structural design of the solar collectors on the roof of the building, and analyze its design points; analysis of the case of south construction and other azimuth direction corresponding collector best angle, as well as the relationship between architecture and the best azimuth angle; quantitative calculation ofvcollector and the different forms of the roof of the effective collector area, space utilization and roof area, etc. putting forward one kind of channel type collector form couple roof,it can effectively solve the roof utilization rate and ease of maintenance of the collector, the lack of security and other issues.Fourth, the life cycle and building a solar hot water system for the calculation of life-cycle period, to assess the form of rooftop solar collectors analysis, including an assessment of the collector size, energy efficiency, and other economic and environmental benefits. After considering the impact of the operating cost of the system equipment replacement, equipment, collection efficiency of the system, capital costs, heat loss and other factors to determine the mathematical model and calculation method evaluation. And each roof collectors form in Guangzhou as an example, the mathematical model instantiated analysis and verification.Research in this paper will help promote the use of scientific assessment and the overall efficiency of solar water heating system solar hot water system in the building, but also provide an intuitive basis for decision-makers in the selection and evaluation of solar hot water systems.
