<p>The system delivers fresh air into a room by generating air jets near an opening to the outside and directed towards the interior, thus forming a depression to draw the fresh air in. These jets can be formed by warm air, and the stale air can be discharged via other openings below these jets. Fresh air can be introduced near the ceiling, and pref. parallel to it, utilising the Coanda effect. The jets can be formed by nozzles adjustable for angle.</p> |
