Air conditioning vent refers to the exhaust outlet of the indoor air conditioner unit, which can be mounted on the wall of the unit or placed directly outside it. It is used to expel hot air from the indoor unit to lower the room temperature, and also to bring in fresh outdoor air into the room.

Common types of air conditioning ventilation outlets include double louvre outlets and self-hanging louvre outlets. Double louvre outlets have two adjustable angle blades that can be adjusted to control the spread angle of the supply air stream, which can also be used to change the direction of the air flow; adjusting the longer blades allows the supply air stream to adhere to the ceiling or incline at a certain angle (when supplying warm air). Self-hanging louvre outlets rely on the natural下垂 of the outlet blades to isolate the exchange of indoor and outdoor air. When the indoor air pressure is lower than that of the outdoor air, the air flow will blow the blades open to exhaust outward, while outdoor air cannot enter the room.

When selecting an air conditioner vent type, choose based on the actual situation and personal preference. Besides the vent type, factors like vent size, location, orientation, filter installation, and air distribution method should also be considered.
