论文中文摘要:
框架结构建筑中的填充墙作为外围护结构的重要组成部分,其保温隔热性能的优劣会直接影响到建筑的总能耗。如何使墙体的节能构造更好地适应不同气候条件是本文研究的重点。由于自保温墙体在不同地区的节能适宜性研究目前还开展的较少。因此,针对自保温节能填充墙在不同气候区的应用研究有着重要的意义。 本文首先阐述了我国的建筑气候区划和气候特点,以及不同地区的气候条件对建筑能耗的影响。其次,从人体热平衡角度出发,分析了热平衡因子对人体热舒适性造成的影响,以及室内外环境因素对室内热环境形成的作用。通过对比三种不同构造形式的外墙保温系统,指出自保温墙体所拥有的突出优势。归纳了不同气候区的外墙应达到的节能设计要求。并依据各气候区的外墙传热系数限值,计算出不同节能墙体材料所需的最小厚度,还结合所选材料的规格尺寸,提出了不同的自保温节能填充墙构造方案,并验算其热惰性指标。确定了满足节能设计要求的填充墙构造措施。为了进一步验证其节能效果,本文利用清华大学开发的DeST能耗分析软件,重点研究对比分析了在选用不同自保温节能墙体构造时建筑的自然室温、全年采暖与制冷负荷以及传热系数、热惰性指标等参数变化对建筑负荷的影响及节能效果。 结果表明:在严寒和寒冷地区,采用蒸压加气混凝土砌块与保温材料复合而成的不同厚度的自保温砌块,对于框架结构填充墙既可以满足相应的节能标准,建筑全年热负荷也会随着保温层厚度的加大而逐渐减少。而在夏热冬冷和夏热冬暖地区,可直接采用蒸压加气混凝土砌块、节能页岩空心砌块或者陶粒混凝土空心砌块,就能满足相应的节能要求,而建筑全年负荷的大小控制则需同时兼顾墙体的传热系数和热惰性指标的要求。研究得出:在夏热冬冷地区运用自保温墙体节能技术最为适宜,可供选择的保温材料种类较多。 综上所述,节能的自保温填充墙是一种很好的节能围护结构,可以广泛应用在各类框架结构建筑中,它的研究必将为今后的节能建筑提供更加广阔的应用前景。
论文外文摘要:
Infill walls of external wall is an an important part of the envelope structure of frame builing, and its thermal performance will directly affect the building's energy consumption. How to make the wall structure more suit different climate is the focus of this paper. Research on energy-saving suitability of self-insulation wall in different zone is very few. In view of this, research on application of self-insulation energy-saving infill wall in different climate zone has an important significance. Firstly, the paper introduces Chinese climate zone and weather conditions, and the influence of climate on buiding simulation in different place. Then it analyzes the influence of thermal comfort and heat balance factors from the perspective of human thermal equilibrium, and indoor environmental factors on indoor thermal environment. It shows that self-insulation wall has more advantage than other two wall heat preservation. Summarizes the requirements of energy-saving design in different climate zones. Calculating minimum material thickness required to meet energy-saving requirement according to climate zone facades heat transfer coefficient value by the size of materials. Then proposes different self-insulation energy-saving wall construction programs, checks the thermal inertia index, get some kinds of wall construction design to meet energy-saving requirements. In order to compare the energy saving effect, use Tsinghua DeST energy analysis soft, focus on room temperature and heating load and cooling load of different self- insulation wall buiding, as well as the heat transfer coefficient the impact on the building loads and energy-saving effect, thermal inertia index and other parameters change. The results shows that: in severe cold and cold climates, using different thickness autoclaved aerated concrete block structure with insulation material as a framework for building energy-saving wall insulation materials can meet the appropriate standards and buiding load will decrease by the inrease of insulation material. In hot summer and cold winter climate zone and the hot summer and warm winter climate zone, using autoclaved aerated concrete blocks, hollow blocks and saving shale ceramsite concrete hollow blocks, corresponding to meet energy efficiency standards, and the building load need both consider K and D. Studies show that in the hot summer and cold winter zone, self-insulation wall is the most appropriate, the insulation material can be used more. In summary, the energy-saving self-insulation infill wall is a good energy-saving building envelope, and it can be used widely in all types of frame structure buildings, its research will provide a more broad application prospects for future energy-saving buildings.
