Ventilation System of Classroom

摘要

The present invention relates to a ventilation system for a classroom, which is installed in classrooms or various lecture rooms in which a blackboard is installed to suck and remove dust generated when the written blackboard is erased without influence on a human. Moreover, polluted air of the classrooms or the lecture rooms is discharged to the outside, and clean outdoor air is supplied to the inside, thereby keeping the inside clean and pleasant all the time without opening windows. The ventilation system for a classroom comprises: a main body configured to discharge stuffy indoor air to the outside and supply outdoor air to the inside; a humidification inducing means configured to humidify outdoor air supplied to the inside and remove contaminants; a vessel configured to purify contaminated water to reuse the purified water; a dust removal means configured to remove dust from the blackboard; and a control unit configured to control the main body, the humidification inducing means, the vessel, and the dust removal means.
