Abstract


In this paper, through the practice of renewable energy zero energy building demonstration project to study the feasibility of the use of solar hot water heating system to replace conventional energy sources in Wuhan, as well as the use of solar energy collector of the east and west walls of the radiation to produce hot water heating feasibility; Wuhan is located in the hot summer and cold winter zone with its own characteristics, the use of solar energy, and building the system of building energy consumption, especially in the hot summer and cold winter zone has unique characteristics of the climate and its characteristics of solar radiation, according to the specific local solar energy resources, make maximum utilization. This study include: the different facades of solar radiation, project energy consumption status, solar heating collector area of ??its impact factors and installation of solar hot water collectors on the indoor temperature changes. Renewable energy zero energy building demonstration projects, for example, choose ECOTECT software China University of Science and Technology College of Architecture and Urban Planning winter heating simulation analysis renewable energy zero energy building demonstration project, the first simulation analysis project throughout the winter heat load and its influencing factors, to draw different months of heating heat load indicators in the region; combined with building heating demand, the paper by changes in solar radiation values ??of different facades the solar collectors factors were further the calculation and analysis; further determined by analysis of the resulting position of the solar radiation intensity Project East West wall solar hot water collector area; concluded last simulation analysis of solar collectors on the indoor temperature for the summer and cold winter areas east and west walls of solar hot water heating provides a theoretical reference. The the project solar hot water heating system using flat plate solar collector collector, heating, floor air supply heating and other heating methods existing in the region than the solar hot water heating does not require city grid power supply and traditional air-conditioning compressor, the entire building demonstration projects non-polluting, low running costs, realize the zero-energy buildings. Wuhan city as a typical summer and cold winter area of ??the middle and lower reaches of the Yangtze River in China for its architectural features and climatic characteristics of solar hot water systems and building design has practical significance, but also for the hot summer and cold in winter and winter heating design provides a theoretical reference, and the design and optimization of the zero-energy buildings in hot summer and cold winter zone provides a theoretical basis and design criteria.
