Shandong Pingyuan County Green No.7 Middle School Teaching Building Ventilation Technology Design Research

In recent years,with the continuous expansion of the number of secondary schools,the construction of school campus in Shandong into a new peak.On the school planning and construction more and more attention by the domestic scholars,but mostly on the research and exploration of colleges and universities,the focus on the secondary school campus in the initial stage,such as: Henan primary and secondary schools green star campus design methods,Shandong Province Primary and secondary school teaching facade transformation and energy-saving suitable technology research,green building design and application of the comparative analysis of the situation.But for the secondary school campus wind environment design research is still relatively small.At present,secondary school teaching construction conditionally using air conditioning,mechanical ventilation.For the third line and below the city middle school mostly use the fan,direct window ventilation way.However,due to the high density of middle school teaching buildings,the demand for indoor fresh air is large.So the use of natural ventilation is the most simple and most convenient way to improve the indoor air environment,but also can achieve the purpose of saving energy.At present,there are six high schools in Pingyuan have been built.There are some fans in the teaching building,some teaching buildings and even no fans.In the summer outdoor high temperature,lack of ventilation,the classroom comfort is very poor,The teaching building in the winter can meet the classroom heating but can not meet the requirements of winter indoor fresh air.Based on the discovery of the above problems,this paper takes the seventh middle school of Pingyuan county as the research object.Based on the analysis of the ventilation potential of the plain county,according to the present situation of the seventh middle school in Pingyuan County.Then put forward the design strategy of the retrofitting design and use thesimulation software to simulate and optimize the site wind environment.After the transformation,summed up the design strategy for the middle school building planning and design in the ventilation design strategy for the After the planning and design of secondary schools to provide reference.After solving the wind environment of the site,the ventilation of the teaching building for its monomer was studied.The factors influencing the design of the building floor and the ventilation design were explored.The simulation was carried out to determine the best natural ventilation scheme,The use of natural ventilation is difficult to meet the needs of indoor ventilation classroom,designed a complete set of auxiliary ventilation program.The final use of ventilation and the amount of fresh air on the classroom indoor ventilation effect was verified for the future design of secondary school building certain design reference.
