Abstract (en)
Ventilation system disposed in a building construction. The intention is, on the one hand, to provide a feed of fresh air originating from outside into a room while, on the other hand, recirculation of air originating from the room must be possible in that room. For this purpose, a ventilation system is present which extends through the wall of a building construction so that air can be drawn in through it from outside. Feed of this air is regulated by a valve disposed in the duct. Furthermore, a feed opening for air originating from that room is present in this duct which extends to a heat exchanger. This air feed can also be opened and closed with the aid of a gate valve. A common operation is present in such a way that, when the opening for outside air is closed, the opening for recirculation is opened to the maximum extent, and vice versa. A manifold is present on the end of the duct which can be connected to a heat exchanger, in particular the underside thereof.
