| The teaching building is the core place of the students’ learning and life,the indoor ventilation directly affects the physical and mental health of students and learning efficiency.In terms of construction of hygiene,the natural ventilation can effectively reduce building energy consumption,providing fresh and improve indoor air quality,promote people’s physical and mental health.The existent teaching building energy-saving for section,compact function,often appear in the northern cold region.But in China’s education mode,the curriculum arrangement requirements,students’ daily average of at least 50% of the time spent in the classroom,when the class time is long,the corridor of the teaching building of multimedia classrooms and corridors will appear poor air circulation problems,seriously affect the quality of the indoor air and the quality of teachers and students in class,study and solve the problem of natural ventilation in the corridor teaching is of great significance.In this paper,through research teaching building and the research status of natural ventilation and results at home and abroad,from the basic principle of passive natural ventilation,implementation,and evaluation index analysis of the basic theory of natural ventilation and technical requirements.Study on existing in teaching healthcare facilities as the prototype,choose 12 teaching building D unit in hebei university of technology as the research object.First of all,this article selects the typical cold areas of higher school teaching building as the research object,the wind speed and temperature field measurement inside and outside the classroom space,analyzes the factor influencing teaching healthcare facilities within the indoor natural ventilation and its potential to optimize the design of the improvement.Secondly,in view of the existent teaching building in typical operating characteristics in everyday use,comprehensive consideration of indoor natural ventilation requirements,through the indoor composite human activities influence strategy to construct the indoor natural ventilation,and follow the climate adaptability design strategy,horizontal air vents and vertical ventilation shaft of architecture.Third,through CFD numerical simulation,intuitive,the feasibility of quantitative analysis of strategy,optimizing the construction design and improve the existent teaching building ventilation performance.Through the reasonable horizontal and vertical ventilation design can solve the existent teaching buildings occupied in ventilation,poor air quality problems.Comparative analysis it is concluded that the teaching of healthcare facilities within the influence of natural ventilation parameters,after the quantitative analysis of the optimal values of the parameters is obtained under different conditions,scope of relatively high quality and the advantages and disadvantages of change.The research results can provide reference basis for architect’s design work,which benefits at the design stage to control the indoor natural ventilation design. |
