In this study, considering the outdoor air quality when natural ventilation estimated that high concentrations due to the closure of the opening, that aims to determine the impact on the reduction of cooling load.
We calculate the airflow and contaminant concentration distribution with CFD analysis in the three models, the results are reflected, thermal and airflow network analysis was performed by annual meteorological data.
One result of analysis that openings were restricted to prevent the flow of outdoor pollutants, total natural ventilation time was about 50% shorter. And the cooling load was decreased by 10%.
