Air conditioning ventilation outlets refer to the exhaust outlets of the indoor air conditioning unit, which can be mounted on the wall of the indoor unit or placed directly outside it. They are used to expel hot air from within the indoor unit to lower the indoor temperature, and also to introduce fresh outdoor air into the room.

Common types of air conditioner ventilation openings include double louvre grilles and gravity louvre grilles. Double louvre grilles feature two adjustable blades that can change angles; the short blades are used to adjust the dispersion angle of the air flow and can also alter the direction of the air; while adjusting the long blades can make the air flow adhere to the ceiling or tilt at a certain angle (when heating air). Gravity louvre grilles rely on the natural下垂 of the grille blades to isolate indoor and outdoor air exchange. When the indoor air pressure is lower than the outdoor, the air will blow the blades open to exhaust outside, and outdoor air cannot enter the room.

When selecting an air conditioning vent type, it's essential to choose based on the actual situation and personal preference. In addition to the vent type, factors such as size, placement, orientation, filter installation, and air distribution method should also be considered.
