Air conditioner ventilation outlets refer to the exhaust outlets of the indoor 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 the indoor unit to lower the room temperature, and also to introduce fresh outdoor air into the room.
Common types of air conditioning ventilation grilles include double louvre grilles and gravity louvre grilles. Double louvre grilles have two adjustable blades that can change angles, with the short blades used to control the diffusion angle of the supply air flow and can also redirect the airflow; adjusting the long blades allows the supply air to adhere to the ceiling or incline at a certain angle (when heating). Gravity louvre grilles rely on the natural下垂 of the grille louvres to isolate indoor-outdoor air exchange. When the indoor air pressure is lower than the outdoor, the airflow opens the louvres to exhaust outward, while outdoor air cannot enter the room.
When selecting an air conditioner vent type, it's essential to choose based on the actual situation and personal preference. Besides the vent type, factors like size, location, orientation, filter installation, and air distribution method should also be considered.
