Research On The Design Of The Solar Water Heating System Integrating With The Architecture In Shenzhen

The shortage of the energy has threaten the development of our national economy, so people more and more attach importance to the exploiture and application of new energy and renewable energy. At present during the thermal applications of solar energy, the solar water heating system has fully developed in technology, and has the the most competitive power and its application is widespread, at the same time the industrialization of solar water heating system has also developed rapidly. The design of solar water heating system integrated with the architecture will not only open a broader space for solar energy, but also contribute to save the national energy. The development of economy and population in Shenzhen is so fast that the demand of hot water for life increased constantly. And Shenzhen situated in the Hot summer and Warm winter area and the solar radiation resources in Shenzhen is relatively rich. And the styles of architectural in this city are multiplex. So researching on the design of solar water system integrated with architecture has the practical significance.Compared to the conventional way of hot water supply, the obervious difference of the solar water heating system is the design of heat source. At first summarize the overseas advanced experience and discuss the installation of solar solar thermal collector from the point of esthetics. And then based the characteristic of Shenzhen solar radiation and architecture, analyze the best azimuth and tilt angle of solar thermal collector, and use Tsun 6.5 to analyze the shade between typical buildings for locating the solar thermal collector. By testing the practical project which solar thermal collector installed on the wall, analyze the practical effect of the system running and compare the performance of different kind of solar thermal collector in different weather in order to provide the data support for choosing and installing the solar thermal collector.In my paper, using the TRNSYS (Transient System Simulation)to simulate the testing system, compared the result discrepancy between the testing and simulation to comfirm the reliability of simulation. And then carry on the whole year's dynamic simulation by TRNSYS for a hypothetic solar water heating system with the hot water supply and the assistant heating centralized. Compare the simulation result about the solar fraction and the heat source efficiency for different solar thermal collector with different azimuth and tilt angle. And synthesize the price of energy, solar thermal...
