It is very important to prepare ventilation measures in buildings. In particular, the importance of indoor ventilation has been further emphasized due to the COVID-19. In this study, the window-attached ventilation panel that combines mechanical ventilation and natural ventilation was developed for ventilation of school classrooms, which is a typical densely populated facility, and its performance was verified through experiments. As a result of the experiment, when the airflow outlet of the ventilation panel faces the center at an angle of about 45°, and the smaller the panel area, the higher the airflow velocity and airflow by airflow induction. When the airflow rate of the impeller is high, the air flow speed of the diffuser increases, which increases the induced air flow, so the ventilation air volume is also high. When the windowattached ventilation panel was applied to a classroom having a general volume, about 12 ventilation cycles could be satisfied. |
