夏热冬冷地区不同墙体结构的保温层厚度分析
Analysis on Thermal Insulation Thickness of Different Wall Structures in Hot Summer and Cold Winter Zone
摘要
Abstract
Selection of appropriate insulation materials and thickness is an important way to realize the building energy saving.A mathematical model to calculate the optimum insulation thickness of materials is established in hot summer and cold winter zone.The economy of XPS, EPS, PU, glass wool and aerogel insulation materials was analyzed for three different wall structures which was shale hollow brick, aerated concrete block and reinforced concrete.It is indicated that the economic thickness of the PU used in shale hollow brick, aerated concrete block and reinforced concrete are 53 mm, 43 mm, 62 mm, respectively.The adaptability of PU for primary wall is better compare to other conventional insulation materials for its appropriate economic thickness, low total cost and shorter payback period.Moreover, the adaptability of aerogel insulation materials for three wall structures was analyzed.It is evident that the reinforced concrete wall is better suitable for aerogel insulation materials due to the shorter payback period and better economic benefits.The results are of great significance for the structural design of composite wall and building energy saving of aerogel insulation materials.关键词
