Use of perforated acoustic panels as supply air diffusers in diffuse ceiling ventilation systems

Ventilation is needed for diluting and removing the contaminants, odour and excess heat from the building interior. It is important that the occupants perceive the ventilated spaces as comfortable. Therefore, the supply air should reach all parts of the occupied zones.
Troldtekt A/S has been manufacturing perforated acoustic panels for the last 13 years. The panels can be used not only in applications related to acoustics but also as low pressure drop supply air diffusers, particularly in diffuse ceiling ventilation systems. The present study verifies on a theoretically level the performance of the panels and empirical findings are examined through the use of CFD, computational fluid dynamics.
