【摘要】：随着我国经济的快速发展与能源消耗矛盾的日益加剧。能源问题成为我国发展重要问题之一。根据数据显示建筑中能耗占社会总能耗的三分之一，能耗为缓解我国能源危机，太阳能作为丰富无污染的可再生能源，被广泛开发利用。近年来，太阳能在建筑中应用逐渐走向规模化，而针对规模化应用研究却很少。本文以合肥市可再生能源示范城市建设为契机，以合肥市太阳能建筑一体化规模化应用城市示范为研究对象，以城市示范中的项目为研究载体，通过对项目规模化应用示范项目的统计分析，在文章的第二章中提出了两个方面问题。第一个问题是针对太阳能建筑一体化系统，结合合肥市2009年以前可再生能源建筑应用的基础条件和可再生能源建筑应用示范城市两年的建设项目，发现合肥市太阳能建筑一体化系统在规模化应用系统中存在集热的倾角朝向、透光率对系统集热效率影响、结合安全度三个层面问题。第二个问题是示范项目在引领城市示范推广中获得了国家资金补助，针对规模化应用中绩效评价，合肥市缺少可靠的绩效评价指标体系。 文章第三章对第一个问题进行研究，主要运用Ecotect生态建筑大师软件、太阳能能效监测实验平台和一体化结合的构造分析等方法进行问题分析。最终得出合肥市在正南朝集热器的倾角20°较为合适，20°至40°之间全年得热率相差不大，，在实际工程中应用可根据实际情况选择；同时通过建立的实验平台模拟太阳能光热系统在不同透光度情况下的热性能分析，得出随着分体式平板集热器表面的透光性能降低，水温上升的趋势有明显的下降，辐射量的大小也影响着水温前期的不规则变化；一体化结合的安全性能分析是以阳台壁挂式为研究对象，对结合方式进行构造分析，提出在建筑设计之初考虑系统的结合应用方式，设计阳台时延长挑梁40cm左右来降低集中荷载，从而提高安全度。针对第二个问题第四章做了相应研究，合肥市规模化应用城市示范在政府配套资金的基础上，以工程示范为载体，建立合肥市太阳能建筑规模化应用三级效果评价指标体系，分别从建设指标、效益指标、资金指标三个方面，建立合肥市两年来规模化应用的效果的评价模型，为规模化应用提供可靠直观的评价方法。
[Abstract]:With the rapid development of our economy and energy consumption contradictions are increasingly intensified. Energy problem has become one of the important problems in China's development. According to the data, energy consumption in buildings accounts for 1/3 of the total energy consumption of society. Energy consumption in order to alleviate the energy crisis in China, solar energy as a rich non-polluting renewable energy, has been widely used. In recent years, the application of solar energy in architecture has gradually moved to scale, but there is little research on scale application. This paper takes the construction of the renewable energy demonstration city in Hefei as the turning point, takes the large-scale application of solar energy building in Hefei as the research object, and takes the projects in the urban demonstration as the research carrier. Through the statistical analysis of the demonstration project of large-scale application, two problems are put forward in the second chapter of this paper. The first problem is the integration of solar energy construction system, combined with the basic conditions of renewable energy construction application before 2009 and the two-year construction project of the demonstration city of renewable energy construction application. It is found that in the large-scale application system of solar energy building integration system in Hefei, there are three aspects of the problem of heat collecting angle orientation, the influence of transmittance on the heat collection efficiency of the system, and the safety degree of the system. The second problem is that the demonstration project in leading the urban demonstration and promotion of the state funds subsidies, in view of the large-scale application of performance evaluation, Hefei lack of reliable performance evaluation index system. In the third chapter, the first problem is studied, which mainly uses the software of Ecotect ecological architecture master, the experimental platform of solar energy efficiency monitoring and the integrated structural analysis method to carry on the problem analysis. Finally, it is concluded that the inclination angle of the collector in Hefei is more suitable than 20 掳in the south dynasty, and the annual heat yield is not different from 20 掳to 40 掳, so the application in practical engineering can be selected according to the actual situation. At the same time, by simulating the thermal performance of solar photothermal system under different transmittance, it is concluded that with the decrease of the surface transmittance of the split plate collector, the rising trend of water temperature is obviously decreased. The magnitude of radiation also affects the irregular change of water temperature. The safety performance analysis of integrative combination is to take balcony wall hanging type as the research object, carry on the construction analysis to the combination mode, put forward to consider the combination application way of the system at the beginning of the architectural design. In the design of balcony, the 40cm of cantilever beam is prolonged to reduce the concentrated load and the safety degree is improved. According to the fourth chapter of the second problem, the author has done the corresponding research. On the basis of the government supporting funds and taking the engineering demonstration as the carrier, the scale application of Hefei solar energy building scale application three level effect evaluation index system has been set up on the basis of the government supporting funds, the third level evaluation index system of the scale application of the solar energy building in Hefei has been established. From three aspects of construction index, benefit index and fund index, the evaluation model of the effect of large-scale application in Hefei in the past two years is established, which provides a reliable and intuitive evaluation method for large-scale application.
