| Our construction sector has been accompanied by rapid economic development,and the construction sector is now forming a huge industrial size.In view of the current trend in support of carbon neutrality and reduced energy emissions,it is particularly important that buildings reduce energy consumption in order to ensure environmentally sustainable development.On June 25,2020,the province of anhui will begin full implementation of energy saving standards in housing buildings by 65%.The cordon structure plays a crucial role in energy saving,while the exterior Windows are the environment of open interiors and the exterior,its role in energy saving is obvious.Studying the impact of external Windows on energy consumption in buildings,adapting the parameters of external Windows,selecting cost-effective materials for the window,optimizing design programs,will be of great benefit to the construction energy industry.This article first explains and summarizes the current state of energy and architectural consumption in our country,the importance of case studies,as well as the progress within and outside the country and the status quo,which shows the necessity and relevance of the studies in this article in the light of the relevance of the current state of domestic energy consumption.At the same time,progress in internal and external structural environmental studies has been analysed,which shows that energy-intensive construction in our country is lagging behind that in our country and that it needs to be improved compared to European and American countries of the same period.At the same time,the main theoretical and research directions of the cordon structure are presented in a more systematic way,on which the content and methods of research of this article are proposed.Then select public buildings and residential buildings for systematic simulation of energy consumption compared to the outer dest software Windows,the outer Windows,the thermal work of the outer Windows,the natural ventilation.The directed ratio of the window walls to the installation of this model is 0.3,as well as four horizontal intervals to simulate the effects of changes depending on the slope to the bottom of the window and calorie cooling on the air-conditioning systems in the building.Having calculated the range of optimal window ratio directed towards the angyin region: the east-west window ratio should be somewhere between 0.341-0.351;The ratio of the north window to the wall shall be between 0.406 and 0.416;The relation of the south window to the wall shall be between0.439 and 0.449.The angyin region mainly USES traditional aluminium window frames for the assembly of conventional one-side Windows,which compare eight types of exterior Windows,such as aluminum window frame with conventional fine finishing,installation of aluminum alloys conventional empty,aluminum alloys low-e.The angyin region is a typical summer heat and winter region,accounting for about 78% of total energy consumption throughout the year.The thermal insulation of external Windows during the summer should be fully taken into account,as well as the fact that the assembly of materials that significantly increase the cooling coefficient and have a lower thermal conductivity coefficient in the steel window frame,while the total construction load throughout the year is low and conducive to economic and technological development in the angyinga area.This program provides25.62% of the energy for heating,9.55% for cooling and saves 11.21% of the total annual load compared to the traditional single-barrel aluminum window.Eleven analog workers were designed to study the effects of thermal work on buildings on cold and thermal loads and energy consumption through natural ventilation.A primitive exterior window with a normal 6mm boson.Working conditions 2-5 and 6-8,respectively,are established to study the effect on energy consumption on window attenuation coefficient sc and heat transfer coefficient k;In order to have an effect on the natural number of ventilation,set conditions 9-12 and compare them to 3.Simulation shows that the reduction of thermal conductivity of external Windows k and shadow coefficient sc increases the thermal performance of external Windows,meeting the requirements of energy saving in construction,and that the size of both types has an inverse correlation with the effect of energy saving.As the number of recirculations decreases,the biggest cold and aggregate cold load for the whole year decreases.The maximum and aggregate refrigeration load is substantially reduced when the oxygen level drops from 8 /h to 5 /h and to 3.5 /h;But the decrease decreases from 3.5 /h to 2 /h and 1 /h respectively.The largest amount of cooling for the air-conditioning building during the year when the ventilation level is 5 /h.Finally,a general analysis of the impact of energy intensity on the energy consumption of the building through the establishment of two-factor heat transfer amplitude of the wall body and the quantity of ventilation taken from materials commonly used in the angye region gives 36 jobs in free combinations with six different quantities of processing.Modelling shows that when the ventilation level is to be determined,the combined annual volume of cold and thermal loads decreases accordingly as the heat transfer coefficient decreases;While the heat transfer coefficient has to be determined,the combined annual load on the cold and thermal heat load respectively decreases with the reduction of oxygen,the diagonal is distributed diagonally in parallel distribution mode.respectively,the difference between the heat transfer level twice or more,negative dependence on energy during the heating season of the building.The higher the heat transfer coefficient,the less load on the building per hour after hour,the less it is consumed,the higher is the energy consumption coefficient,as well as the weaker dispersion in general,which means that the energy transmission coefficient of the air conditioner decreases with the increase in the heat transfer coefficient and represents a correlation.Figure[47] table[18] reference[113]... |
