Design Research Of Solar Water Heating System Into High-rise Residences

After Copenhagen UN Climate Change Conference, China brings forward own standard,"low-carbon"will become the life subject, which is extended actively by the country. The green energy will go on to exert the huge promoting role. With the flourish of high-rise residence, the serious energy-waste questions gradually appear up. The domestic hot water load of the total construction energy consumption is 10% to 20%.Adopting solar hot water will become the development trend. However, during the actual application, there are many questions in the aspects of the coordination between architectural design ,the solar equipment and the property management mechanism in later period. These questions block the further development of the solar water heating system in the high-rise residences.From the aspect of the architectural design, according to the common solar water heating system used on the high-rise residences, the thesis compares the application characteristics and the hot water cost ,and puts forward the advantage and the development potential of the concentrated solar water system. Then, aiming at the integrating methods of the concentrated solar water system into high-rise residences, and the relations between the management in later stage, the thesis conducts the quantificational and qualitative analysis, putting forward the reference for architects to make the integrated design on the solar water heating system on high-rise residences.Here are the research contents of the thesis:(1) Combining with the concentrated solar water system on one high-rise residence, the author tidies up the testing data on the June to October at 2009, and calculates solar insuring rate , auxiliary heat source heating rate and hot water cost at the different weather conditions.These testing data will provide the supporting for the design analysis.(2) The thesis will investigete and study the utilization situation of the solar hot water on the high-rise residences,and analyzes the rule of the heat application of the dwellers, bring forward the average water consumption per person in different economic area. This part of content will confirm the collector area,heat storage volume and the establishment of the management policy for architects.(3) The thesis quantitatively calculates the effective gaining heat of the different types of the collectors and the roof , putting forward one kind of the idea of the keen asymmetrical couple roof.The thesis analyzes the matched plan combination,and calculates the heat collected scale.(4) The thesis quantitatively studies the relations between the elevation collector and the window shading, analyzing the suitable dip and distance ,and caculating the effective gaining heat between the collector and the elevation. Through the sunshine simulating to the typical layout of the high-rise residences,the thesis analyzes the lowest suspension position on the south facade,which will help the architects to reasonably arrange the position of the heat collectors in the phase of the facade design to avoid the larger adjustments because of the sunshine affects.(5)The thesis analyzes the hot water cost and the related effect of the centralized solar water system,putting forward one suit of the management and way of measurement adapting the centralized solar water heating system in the high-rise residences.
