Application Research On Energy-Saving Technology Of Wall Materials In Rural Areas Of Southern Shaanxi Province

With the development and progress of rural economy and environment,the construction of new countryside has been constantly promoted,and the energy conservation of rural buildings has also become the key project of China's energy planning.As the main component of building envelope,building wall is also the most important part to solve the energy saving development of rural residential buildings.Building wall materials must be promoted realistically,understand the current situation of rural residential building wall materials and the existing problems,find suitable for the local wall materials or research new type wall materials,further research on wall body energy saving construction technology,test and analysis through research to provide the theory basis of actual rural construction.In southern shaanxi rural residential construction in order to study and improve the indoor thermal environment of the status quo,research of native ankang,hanzhong rural areas of field investigation and site survey for many times,and local representative residential building indoor temperature real-time monitoring,understand the current residential construction status quo of southern shaanxi rural residents and analyze the problems.Paper USES the combination of field investigation and numerical simulation analysis,from the southern shaanxi rural local existing on the research of wall materials,combined with the climate conditions of the southern shaanxi,policy documents and apply to the local regulations,for in southern shaanxi of new wall materials suitable for the technical performance index of the system of induction and calculated,and further to the different ways of wall materials in the practical application of tectonic comparison and choice,then select a cell,heat transfer calculation software calculation through PTemp line wall average heat transfer coefficient of different materials,at the same time get the index of thermal inertia in the material.Finally combining the rural residential building energy efficiency design standard "(GB/T 50824-2013)in the value of indicators to analyze all kinds of wall materials,put forward suitable for southern shaanxi rural building wall materials and the optimum structure of wall materials under different structure types,the residents' quality of life and has a certain increase and improve indoor thermal comfort,at the same time,in southern shaanxi rural residential building palisade structure for material selection and construction technology application type guiding opinions,so as to promote the development of rural building energy efficiency.
