Ventilation grilles are air distribution devices for ventilation and air conditioning systems for supply and exhaust air. They direct supply air into the room. Ventilation grilles with adjustable slats allow you to change the direction of air flow if necessary. As a result, air flows are mixed with good distribution of air jets throughout the room. The ejection level decreases as the air flow decreases, i.e. The air flow speed decreases as the distance from the grille increases. The distance at which the air flow speed reaches a certain value (eg 0.2 m/s) is called the projection distance. As a result of the Coanda effect, a supply air jet from wall grilles located close to the ceiling achieves a greater projection distance than a comparable free jet. Single grilles, grille groups and sections achieve different projection distances. In cooling mode, it is necessary to take into account the deviation of the jet in relation to the working area, which increases with an increase in the temperature difference between the supply air and the air in the room and a decrease in the flow rate. In heating mode, the supply air stream is deflected towards the ceiling. This does not have a negative effect on the air flow rate in the work area, but may affect the overall ventilation of the room.
