Numerical Study on Hybrid Ventilation System of Classroom

摘要：

Natural ventilation (NV),relying on openings in the facade,is applicable to a limited range of climates,sites and building types.Hybrid ventilation,which integrates both natural and mechanical systems,can extend the range of buildings and climate within which natural ventilation might be used.However,buildings with hybrid ventilation tend to consume more energy than simple NV buildings,but less than those with air conditioning.This paper simulated hybrid ventilation of a typical Classroom under the climate condition in Beijing with FLUENT software.The research focused on the best cooperation of mechanical ventilation and natural ventilation.The effect of wind speed on temperature distribution in the classroom was discussed.Wind speed improved temperature distribution with high temperature efficiency,but temperature efficiency went down when the wind speed was high.
