Research On Indoor Wind Environment Optimization Design Of Dining Room In University Canteen In Hohhot Area

In the post-epidemic era,people began to pay attention to the health and comfort of the indoor wind environment of buildings.In particular,colleges and universities,which are highly crowded places,should pay more attention to the design of the indoor wind environment of buildings.The dining hall of colleges and universities has a large space span,long depth,many indoor space divisions,high density of people,and air flow is easily blocked.With the increasing design standards and demands of wind environment,it is urgent to improve the indoor ventilation effect,indoor air quality and wind thermal comfort level.The study takes the indoor wind environment of college canteen dining space in Hohhot as the research object.Through literature research,field test,numerical simulation and comparative analysis,this paper analyzes the current situation of indoor wind environment in college canteens in Hohhot,studies the influence law of dining space factors on indoor natural ventilation and optimizes the design verification of the influence law.Finally,the optimal parameters of dining space factors that can improve the indoor wind environment level are obtained.The conclusions of this study have the following three aspects :The study summarizes the influencing factors and evaluation indexes of indoor wind environment in buildings,comprehensively studies the influence of catering space factors on indoor wind environment,and uses average wind speed,air age and PMV index as evaluation indexes to evaluate indoor wind thermal comfort and ventilation effect.The study analyzes the characteristics of wind climate in Hohhot,summarizes the spatial characteristics of college canteens in Hohhot,and puts forward the current situation of indoor wind environment in college canteens.The study establishes a typical model of university canteens in Hohhot,and studies the influence of five influencing factors on indoor wind environment,including spatial layout,spatial orientation,ventilation window,air inlet and outlet and atrium space,and optimizes the indoor wind environment of catering space.This study synthesizes the main influencing factors of the indoor wind environment of the dining space of the college canteen,and puts forward the corresponding optimization design and parameters,which can enrich the optimization theory system of the indoor wind environment of the college canteen to a certain extent,and fill the research gap of the indoor wind environment of the college canteen in the similar climate environment in Hohhot.It has certain guiding significance for the natural ventilation design of the dining space of the canteen building under the same wind climate conditions.At the same time,the indoor wind environment of university canteen buildings in Hohhot is organically combined with space design,and the problem of indoor wind environment of buildings is solved from space in the scheme design stage.The research has certain theoretical and practical significance.
