Study On Indoor Thermal Environment Of Teaching Building In Rural Areas Of Baoding

For a long time,rural schools in China are mainly built by villagers themselves.Limited by economic conditions and insufficient understanding of indoor thermal environment and energy conservation,people only consider the cost when building schools.Although the state has formulated the code of architectural design for primary and secondary schools,few rural school buildings are designed and constructed according to the code of energy conservation and thermal engineering,which leads to problems such as simple envelope structure,poor thermal insulation performance,poor sealing of doors and Windows.With the emphasis on education in China,higher requirements have been put forward for the construction of rural schools.Improving the indoor thermal environment of teaching buildings in rural primary schools is the basis for improving the conditions for running schools and the quality of teaching.For the study of baoding in rural primary school indoor thermal environment,this article to baoding shiqiaotou village elementary school in rural areas and the luodi village primary school,the two primary school teaching building to the ground as the research object,the field test,questionnaire survey,theoretical analysis and numerical simulation method,discusses the baoding rural primary school teaching building indoor thermal environment improvement measures.First of all,for winter and summer,the method of field test and questionnaire survey is used to describe the indoor thermal environment of the teaching building by combining objective and subjective.Through field test and the questionnaire results found shiqiaotou village and the luodi village primary school,the problems existing in the teaching building floor basically has: no heating in the winter the building facilities,low air temperature,infiltration,students to the whole teaching building indoor thermal environment satisfaction is low,and summer indoor thermal environment is relatively comfortable,students to the whole teaching building indoor thermal environment satisfaction is higher;Secondly,the paper analyzes the design factors of thermal environment improvement of teaching buildings in rural areas and the measures to improve the teaching buildings in baoding rural areas.In view of these problems existing in the current situation of the teaching building,on the premise of dealing with the climate and economic conditions in the rural areas of baoding,this paper puts forward improvement strategies from four aspects: planning layout,envelope structure,passive solar energy utilization and heating mode optimization.Finally,the indoor thermal environment of the teaching building improvement plan of shiqiaotou village and the luodi village primary school was evaluated.The Design Builder software was used to simulate the thermal environment before and after the improvement of two primary school teaching buildings.The simulation results of the current situation were compared with the test data to verify the reliability of the software simulation.The simulation results of the current situation and the indoor thermal environment after the improvement were compared to further verify the feasibility of the improvement measures.Through the research of this subject,the paper summarizes the present situation and improvement strategies of the indoor thermal environment of teaching buildings in rural areas of baoding,and puts forward improvement plans,hoping to provide certain theoretical guidance and technical support for the construction,reconstruction and expansion of local primary school teaching buildings.
