Simulation Study On Ventilation Of Primary And Middle School Teaching Buildings With Different Plan Types In Hot Summer And Warm Winter Area

In recent years,the ventilation of primary and secondary school buildings has been paid more and more attention,especially in hot summer and warm areas.As a place where teachers and students learn to work.the ventilation of the teaching building is closely related to their physical and mental health,learning and lif'e.This paper aims to study the different plans of teaching buildings.and learn their different ventilation characteristics.In this paper,CFI)simulation software is used as the main research tool.After the study,it found that the "—",type of teaching building will be the more close to the direction of the flow of the room,the better ventilation in a certain range of' wind direction,Moreover single corridor space ventilation is much better than the double corridor,and the together-space is much better than the sub-space in ventilation.Secondly,in the "L" type of teaching building,as the corner is not transparent.the corner of the room ventilation is poor in the most ventilation angle.But in some specific angles as the wind is blocked,it results in pressure on both sides of the room.The corner of the room ventilation will become better.In addition,different proportions of the plan have different ventilation characteristics,and with the long wing part of the increase,the building can be in a wider range of ventilation angle to achieve better ventilation effect.As the the corners of "T" type teaching building is transparent,so the ventilation situation is different with "L" type.Overall,the best ventilated rooms are generally located at the end of the long wing and short wing which is away from the corner.The worst ventilated room is usually located near the corner.The ventilation is mainly depends on the pressure on both sides of the room.Finally,the results of this study can help architects in the design of teaching buildings based on the ventilation effect of reasonable arrangements for the location of the classroom.And they can also take the overall into consideration of the construction of teaching building orientation.According to this,we can also arrange the classroom position basing on the different ventilation requirements.Requirements of high room can be place in good ventilation place and requirements of low room can be placed in poorly ventilated position,such as staircase,storage room.etc.Therefore,the architects can be satisfied with the functional requirements at the same time,and then do more rational design work.
