Study On The Influence Of Sunshine On Indoor Thermal Comfort Of Farmhouse In Cold Area Taking The Energy-saving Renovation Project Of Existing Farmhouse In Wenzu South Village Of Zhangqiu District As An Example

At present,China’s urbanization process has developed rapidly and achieved remarkable results.Urban residential building environment is becoming more comfortable and energy-saving.However,there are still some problems in rural residential buildings in China,such as single building form,poor indoor comfort,poor thermal insulation,high energy consumption,and serious pollution.Therefore,the lagging development of rural residential buildings has attracted more and more attention of the state.At the same time,under the environment of vigorously promoting clean energy heating,as an energy-saving and effective way to adjust the indoor thermal comfort of farm houses,how to make good use of the sunshine room can not only meet the needs of improving the indoor thermal comfort of rural houses in cold areas of our country,that is,heating in winter,ventilation and cooling in summer,but also take into account the clean and environmental protection,which is of great significance.Research significance.Because sunshine is ubiquitous in the vast rural areas and plays an important role in winter and summer under the cold and hot environment in China,the research object of this paper is located in the cold areas of China.Based on a field survey of 32 farm houses in Wenzu Nancun,Jinan City,Shandong Province,we find that the sunshine room in cold areas in China is relatively simple at present,and the single form can not meet the requirements of normal use.Through questionnaires,local residents were interviewed to understand their living habits,and real data were obtained by indoor temperature and humidity tests in winter and summer,and quantitative analysis was carried out.The problems existing in the sunshine of farm houses in cold areas in China were summarized,and the correlation between indoor thermal comfort was poor.Aiming at the advantages and disadvantages of farmhouse sunshine room in cold regions of China,based on the simulation of typical farmhouse model in cold regions,this paper puts forward a renovation scheme that meets the requirement of energy saving,and uses Ecotect software to simulate and optimize the thermal environment,summarizes and puts forward the optimal design strategy of farmhouse sunshine room in cold regions of China,and quantitatively analyses the actual effect of the optimization scheme for China’s cold regions.The suggestions can be used for reference in the transformation of farm houses in cold areas during sunshine hours.
