Tilluftspunkter

Tilluftspunkter, often translated as supply air diffusers or terminals, are essential components within a building's ventilation system. Their primary function is to distribute conditioned fresh air, known as supply air, from the ventilation unit into the occupied spaces of a building. This ensures adequate indoor air quality by providing oxygen, diluting pollutants, and controlling humidity levels.

The design of a tilluftspunkt influences how the supply air is introduced into a room. Different types exist, each suited for specific applications and aesthetic requirements. Common types include ceiling diffusers, linear slot diffusers, grilles, and swirl diffusers. Ceiling diffusers are frequently used in suspended ceilings, offering a wide range of airflow patterns and noise levels. Linear slot diffusers provide a more discreet appearance and can create specific airflow patterns along walls or ceilings. Grilles are simpler in design and often used where aesthetics are less critical or in combination with other air distribution components. Swirl diffusers create a swirling motion of air, promoting rapid mixing with room air and preventing drafts.

The placement and selection of tilluftspunkter are crucial for effective ventilation and occupant comfort. Incorrect placement or undersized units can lead to uneven air distribution, drafts, and a feeling of stuffiness. Proper design considerations include the room's volume, occupancy, heat load, and the desired air velocity at the occupant level. Noise levels generated by the air passing through the tilluftspunkt are also a significant factor in their selection, particularly in sensitive environments like offices or bedrooms. Regular maintenance, such as cleaning, helps maintain their efficiency and prevent the recirculation of dust and allergens.
