Ventilation grilles are air terminal devices for the supply air and extract air of ventilation and air conditioning systems. They direct the supply airflow 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, with good overall room ventilation. Due to induction, the airflow velocity of the supply air flow decreases with increasing distance from the ventilation grille. The distance at which the airflow velocity reaches a certain defined value, e.g. 0.2 m/s, is called throw distance. Due to the ceiling effect, the supply airflow from wall grilles that are arranged close the ceiling achieves a greater throw distance than a comparable free jet (without ceiling effect). Single grilles, groups of grilles with certain spacing, and linear run sections all achieve different throw distances. In cooling mode, it is necessary to consider 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 overall ventilation of the room.
