Application Of Passive Solar House With Additional Sunshine Room In Self Built Houses In Rural Areas Of Mengcheng County

In the context of the rural revitalization strategy,improving the rural living environment and building a better countryside has become an important strategy in China.As a large agricultural country,China has a huge number of existing buildings in rural areas,and due to the lack of construction technology and professional construction technology of self-built houses,the indoor thermal environment of existing rural houses is poor.In order to obtain a comfortable indoor thermal environment,building energy consumption is large,especially in north China,winter heating leads to environmental pollution,energy consumption increase and other problems;In order to fulfill China’s commitment to achieve no increase in carbon dioxide emissions by 2030 and better implement the concept of "carbon neutrality" and "carbon peak",the research on improving indoor thermal environment of existing rural houses through green renovation is becoming more and more important.This paper investigated the application of passive solar house in rural self-built houses in Mengcheng County,summarized the life and production mode of rural residents in Mengcheng,and sorted out the typical forms of existing self-built houses.By practice,the author applies the building additional sunlight,on a layer of the sitting room temperature and humidity measurement,and analysis of test data for comparison after the application of passive solar house since building a layer of the sitting room the measured data of temperature,humidity,it is concluded that additional between sun type of passive solar houses from building a layer of the sitting room has improve indoor thermal environment effect.Using Designbuilder for typical from the present situation and application of passive solar house building transformation model,by changing the additional sun（material）for passive solar houses,depth,window wall than,after comparing application of passive solar house since the building indoor temperature,comfort simulation data,on this basis to evaluate the advantages and disadvantages of each scheme,The best form of sunshine room for improving indoor thermal environment of self-built house in rural area of Mengcheng county is obtained.Considering the possible overheating of passive solar house in summer,the sun room with the best effect in winter is selected to simulate and analyze the thermal environment in summer.It is concluded that under the premise of reasonably opening the air vent in the sun room,the indoor temperature of the first floor of self-built house will not increase in summer.By mengcheng rural since the building use additional sun type of passive solar house between strategy to improve the indoor thermal environment,change the additional form between the sun and the relevant quantitative simulation from the building indoor thermal environment charts and data,so as to evaluate additional between sunlight on the building indoor thermal environment effect,and it is concluded that the ideal form between the sunshine.Today,with the deteriorating ecological environment and serious energy consumption,energy saving transformation and green development of existing rural houses are becoming more and more important.It is hoped that this paper can bring some inspiration to the green development of self-built houses in mengcheng and even in northern Anhui.Figure [97] table [30] reference [51]...
