Ventilation grilles are air terminal devices for the supply air and extract air of ventilation and air conditioning systems. They guide the supply air into the room. Ventilation grilles with adjustable blades allow for adapting the discharge direction to the local conditions. The result is a mixed flow ventilation in comfort zones and industrial zones, with good overall room ventilation. Induction slows the airflow down, i.e. the airflow velocity decreases as the distance from the grille increases. The distance at which the airflow velocity has reached a certain value (for example 0.2 m/s) is called the throw distance. The supply air jet from wall grilles arranged close to the ceiling reaches a greater throw distance than a comparable free jet (without ceiling influence) due to the ceiling influence. Single grilles, groups of grilles and continuous horizontal runs all achieve various throw distances. In cooling mode it is necessary to take account of the jet deflection towards the occupied zone, which increases as the supply air to room air temperature difference increases and the discharge velocity decreases. In heating mode the supply air jet is deflected towards the ceiling. This has no negative effect on the airflow velocity in the occupied zone, but it may affect the complete ventilation of the room.
Ventilation grilles with gently sloped border, rectangular, for supply and extract air. Function combined with an appealing design. Gently sloped border. Preferably for wall and sill installation but also suitable for rectangular ducts. Ready-to-install component which consists of a border and symmetrically and aerodynamically profiled, horizontal blades with a concealed linkage that allows for adjusting the blades simultaneously.
