Research On Energy-saving Design Of Large-scale Supermarkets In Suzhou Area

In recent years,society has continued to develop rapidly,and great achievements have been made in various fields,but also at a great price.A large amount of energy consumption and CO2 emissions have severely damaged the natural environment,and a series of environmental problems have emerged that have endangered humanity.Long-term development.Therefore,it is necessary to promote sustainable development and achieve energy conservation and emission reduction while developing.Commercial buildings run for a long time throughout the year and consume large amounts of energy.Large supermarket buildings are a type of commercial building.In recent years,they have developed rapidly in China.A large number of large supermarkets have been established in various places.Because of the particularity of its cargo types and sales forms,it has irreplaceable advantages,so it is of great significance to conduct research on energy-saving design.However,currently there are more researches on shopping mall buildings in commercial buildings,and less research on energy-saving design of large supermarket buildings,especially in the Yangtze River Delta area represented by Suzhou,so this article hopes to supplement this aspect.This article first carried out a field survey of large-scale supermarkets in Suzhou,and grasped the basic situation of large-scale supermarkets in Suzhou.Based on the survey,the energy-saving design route was summarized,namely,energy-saving heating,air-conditioning,and lighting and ventilation of large-scale supermarkets.Next,we will conduct in-depth research on heating and air conditioning and lighting energy saving in large supermarkets in Suzhou.The energy-saving design standards of many public buildings were sorted out,and the energy-saving measures of different specifications were sorted out.According to the different energy-saving measures,the energy consumption of lighting and heating and air-conditioning are calculated and simulated.The obtained energy consumption data is analyzed to obtain the energy saving effect and overall energy saving effect of each measure.Some problems in the existing energy-saving methods were found through calculation and simulation.According to the results of the study,specific further energy-saving measures are proposed.Finally,in-depth research is done on ventilation and energy saving in large supermarkets.First of all,the necessity of ventilation in large supermarkets was explained,and natural ventilation was used to maintain indoor air quality during excessive seasons and summer nights.Ventilator ventilation is designed for typical Suzhou large supermarket interior space,and simulation verification is performed using CFD software.Through simulation,it is found that the ventilation of the wind catcher can completely guarantee the indoor air quality of large supermarkets in Suzhou,and the layout and size of the wind catcher with good effect are found out.Through the research in this article,a targeted energy-saving design strategy is proposed for large supermarkets in Suzhou.The results of the study provide a reference for energy-saving renovation of existing supermarkets and energy-saving design of new supermarkets.
