In HVAC a grille is a vent cover through which air is blown into or out of a room for circulation back to the central heating or cooling unit. It is mounted in duct, wall, roof, floor, and ceiling to direct the flow in the air conditioning system. The air grille can be single-deflection and double-deflection type, which single-deflection grilles providing vertical airflow direction control. Meanwhile, double deflection grilles allow both vertical and horizontal airflow direction control.
The air conditioning outlet is simply the terminal equipment used for air supply and returns in the central air conditioning system, which is air distribution equipment. The air supply outlet sends the cooled or heated air to the room, while the air return outlet absorbs the indoor dirty air, forming a whole air cycle, which ensures the cooling and comfort of indoor air while ensuring the indoor cooling and heating effect. Air conditioning outlets are mainly divided into air return outlets, air supply outlets, inspection ports, and external wall outlets.
