<p>Installation for air regulation of a front wall element allowing energy savings, having on its outer face exposed to the elements (2) an outer window pane (3) and an inner window pane (4) with an air channel (5) formed between the two to draw inner ambiant air (6) and another channel for fresh air (7) with a suction opening (7a') for fresh air on the outer face and an opening (7b) for expelling fresh air out of the room. The air channel of the outgoing stream is connected with an outside air outlet (8b') as well as with a heat exchanger (9) located upstream of the outlet through which air going out gives heat to fresh air coming in. The novelty consists in that the air regulation arrangement forms a compact construction element (16) and is exclusively installed inside the room. Preferably, the compact construction element (16) comprises an air regulating box (31) mounted separately, as well as a fan (32). </p> |
