According to the research,there are 650 million square meters of construction reserves in China,of which about one third of the national carbon dioxide emissions.In the construction sector,including public buildings,energy consumption accounts for about 38%of the total construction.With the passage of time,the requirements for building functions are also growing.In particular,from the perspective of energy consumption and environment,it was difficult for old buildings to meet the needs of people’s work and life in the past.In order to promote the smooth development of public buildings,China has formulated a series of regulations and rules,Encourage governments at all levels to actively implement measures to reduce carbon dioxide emissions.At the same time,domestic experts are actively carrying out research on reducing carbon dioxide emissions.They found that the use of fragile technologies,such as regenerative heat capacity of walls,natural ventilation and improving the indoor environment,was "sexual" In addition,many countries and social structural adjustments are aimed at transforming the protection structure around buildings into "value".Therefore,it is necessary to study the application of natural ventilation and thermal coupling technology in public buildings.This paper gives an example of the construction of a building in Huangshan,Anhui province.Using regeneration and ventilation technology in different working environment;From a technical point of view,it provides theoretical support for the reconstruction of the building,and provides suggestions for similar projects.First,through the research and analysis of the current situation at home and abroad,the research methods and approaches are formulated,In order to comprehensively improve the efficiency and research of national construction.Then,with the help of the established mathematical model,the principle of forming natural ventilation,the method of realizing natural ventilation and various factors are highlighted,These factors limit the heat transfer of the structure,the regeneration principle of the building wall,and the factors affecting the heat capacity.After the ANSYS program,the interactive simulation process related to the ventilation system is further studied,This shows that the technology related to natural ventilation is helpful to optimize the indoor temperature field and airflow distribution.Subsequently,the processes related to electricity and natural ventilation are analyzed in this paper.The results show that the phase material is composed of one or more parts.Different from other ordinary heat walls,it can stabilize indoor humid environment through its excellent regeneration performance,This can eliminate peaks and fill valleys by reducing the energy consumption of buildings.The latter uses dest to create the Huangshan construction scheme that needs energy,and analyzes three experimental simulation modes,Phase change and gas as wall materials,reduce their own energy efficiency of the main 9%and 7.4% is the same,line temperature is convenient,overnight hours than non door hours conversion The annual total cooling rate of air conditioning is 5.2%,which is in Huangshan area.It is suggested that the material be used as wall material by phase shifting from natural gas;In addition,we should also increase the window,increase the area of the border,and increase the night valve.When the frequency of opening the valve window is 10 times / h,the power efficiency is 6.3%,but the number of valves increases,3.Horizontal air conditioning improves the speed economically and effectively For Huangshan,the best breathing rate is pole.
