<p>The present invention relates to a ventilation door which is openably and closeably mounted at the boundary of a place, or the entrance of a building. The ventilation door comprises a first ventilation section (10), a second ventilation section (20), a pair of air adjustment members (30, 30') and a grill (40). According to the present invention, a ventilation passageway is formed on a door such as entrance door, room door or the like, which are openably and closeably mounted at the boundary of a place, the entrance of a building, or the place where people come in and out, so as to communicate the indoor/outdoor side of the door with each other via the ventilation passageway, so that the indoor air is ventilated by an air circulation method using the convection phenomenon, whereby the energy required for air conditioning can be saved, as well as the sound insulating characteristic and the watertightness of the door can be improved, to thereby provide a comfortable indoor environment.</p> |
