论文中文摘要:
随着我国能源匮乏与建筑高能耗矛盾的不断加剧,大型公共建筑的能耗已成为人们关注和研究的热点问题。特别是采用了空间结构的大型公建,由于其使用功能的特殊性,导致其能源消耗总量大、波动性大。如何利用建筑外表面积大、屋面开阔的特点,合理利用屋面空间,推广可再生能源的利用,实现太阳能建筑一体化,研究其意义重大,是未来建筑节能发展的必然趋势。 本文以研究太阳能技术在大型公共建筑中的应用为出发点,通过现场调研分析,将其应用归纳为:光热应用、光照明应用、光伏应用等三种应用方式;重点分析太阳能技术组合应用的可行性,提出应根据建筑内部实际需求,合理划分屋面不同应用太阳能接收载体的布置区域,最大限度利用屋面空间,提高太阳能利用效率。其中,光伏技术是未来太阳能技术发展的重点,以光伏应用与屋面的结合技术为主要研究对象展开分析。根据光伏方阵与屋面的结合程度,将其划分为分离式(BAPV)和合一式(BIPV)。从屋面光伏组件选择、光伏组件的布置、组件支承形式选择,以及系统结构设计四方面分析研究两类光伏屋面的体系结构及设计特点。结果表明BIPV式屋面一体化程度高,但体系个性大于共性,设计时应具体问题具体分析;BAPV式屋面的半独立性,在现有光伏技术基础上更利于保证屋面组件发电效率,通用性更高。 归纳BAPV式屋面的设计流程为:光伏组件选择→屋面组件排列→支架选型→支架结构设计。经过综合分析对比,提出光伏组件选择、排列及支架选型的优化方案。支架结构的优化设计,首先,根据不同规范标准的公式构成及计算结果分析,对屋面光伏支架设计风荷载标准值及荷载组合进行对比分析,提出建议使用的屋面光伏支架设计风荷载计算公式和荷载组合;其次,根据上述分析结果,运用Sap2000数值模拟软件对不同风荷载设计组合值情况下的光伏支架结构进行数值模拟分析,分析不同情况下各构件的挠度值,得出支架结构在不同工况下的作用规律,提出优化方案。综合上述结果,给出BAPV式屋面体系的优化设计方案,并结合工程实例,分析验证优化方案的实际可行性及优化效果。 以上海世博会中国主题馆光伏屋面体系为例,对其实际应用效果进行分析,结果表明该体系年发电量约为280万度,理论上可满足建筑主体正常运转340天,且节能减排效果十分可观。因此,将光伏系统与建筑屋面的结合,对于大型公共建筑和社会都具有一定的应用价值和推广前景。
论文外文摘要:
With the growing of contradiction between lack of energy and building energy consumption, large public buildings' energy consumption has become a hot issue of concern and research. Especially the space structure large public buildings, due to the particularity of its using function, leading to the amount of its energy consumption big and volatile. How to use the characteristics of this building exterior area large and roof open, rational use of the roof space, to promote the use of renewable energy; to achieve solar building integration. The study is significance, and it is the inevitable trend of future development of building energy efficiency. This paper studies the application of solar energy technology in large public buildings as a starting point, Through on-site investigation and analysis, to apply it summarized into three application modes: solar thermal applications, lighting applications, photovoltaic applications. Analysis focused on the feasibility of the application of solar technology portfolio. Made a point that should be based on actual needs of building interior, a reasonable division of the arrangement region of different application solar roofing receiving support, to maximize the use of the roof space and improve the utilization efficiency of solar energy. Photovoltaic technology is the focus of future solar technology development, the combination technology of photovoltaic applications and roofing structure is the main object of study to analyze. According to the degree of integration between the photovoltaic array and the roof , Photovoltaic roof will be divided into BAPV roofing system and BIPV roofing system. From PV modules selection and arrangement, the form of PV modules support selection and systems design, to analysis and study roofing system structure and design characteristics of these two classes photovoltaic roof. The results showed that the degree of integration of BIPV roofing is high, but the system's individuality is greater than its commonality, so analyze specific issues should be taken in design; BAPV roof is semi-independence, on the basis of existing photovoltaic technology is more conducive to guarantee the component generation efficiency and it is more common. BAPV roofing design process are summarized as follows: PV component selection → Roofing assembly arrangement → Bracket selection → Bracket structure design. After a comprehensive analysis and comparison, Proposed PV module selection, arrangement and bracket selection optimization. First, depending on different specification standards' formula configuration and calculation results, wind load standard values and load combinations of PV roof stent design were analyzed, Recommend the reasonable wind loads and load combinations calculated; secondly, according to the results of analysis, using numerical simulation software for analysis Sap2000 numerical simulation analysis PV mounting structures in case of different wind load design portfolio value, and Analyzed the deflection of each component under different circumstances to obtain stent structure's role of law and proposed optimization program. Based on the results, given the optimal design of BAPV roofing system, and combined with engineering examples to verify the feasibility and optimal results. Taking Shanghai World Expo Chinese Theme Pavilion photovoltaic roofing system as an example, to analyze its practical application, the results show that the annual power generation of this system is about degrees, and the energy saving effect is very impressive. the normal operation of the main building could be 340 days, and the energy saving effect is very impressive. Therefore, it is a certain value and promotion prospects for large public buildings and community combining photovoltaic system with roofing.
