<p>The present invention relates to a ventilation device for filtering outer air, introducing the outer air into a room after heat exchange with air in the room and discharging the air in the room outside. More particularly, the present invention relates to a heat exchanging ventilation device capable of selecting the inflow of outer air or the circulation of indoor air while replacing a filter in a room. The present invention comprises an air ventilation duct installed at an upper side in a room to have a discharging hole for discharging outer air into the room; and an inflow device for filtering the outer air with the air ventilation duct and introducing the outer air, wherein the inflow device is installed inside a building and has an indoor air adjusting panel for supplying the outer air through a shutter and adjusting the inflow of indoor air toward one side surface. The outer air or the outer air mixed with the indoor air, which is supplied from the inflow device, is supplied to the air ventilation duct by an air ventilation fan. A discharging duct is installed inside the air ventilation duct to be separated from the air ventilation duct and a discharging fan is installed toward the discharging hole of the discharging duct. An inhaling hole is installed on the discharging duct to inhale the indoor air.</p> |
