Functional description

Ceiling swirl diffusers in air conditioning systems create a swirl to supply air to rooms. The resulting airflow induces high levels of room air, thereby rapidly reducing the airflow velocity and the temperature difference between supply air and room air. Ceiling swirl diffusers allow for large volume flow rates. The result is a mixed flow ventilation in comfort zones, with good overall room ventilation, creating only very little turbulence in the occupied zone.

Type DCS ceiling swirl diffusers have fixed blades. The swirl unit required for the swirling air discharge is situated inside the plenum box, concealed by a perforated plate, and hence not visible from the room. Air discharge is horizontal omni directional. The supply air to room air temperature difference may range from –12 to +10 K.

To give rooms an aesthetic, uniform look, Type DCS diffusers may also be used for extract air.

Quick sizing tables provide a good overview of the volume flow rates and corresponding sound power levels and differential pressures.

The minimum volume flow rates apply to a supply air to room air temperature difference of –6 K.

The maximum volume flow rates apply to a sound power level of approx. 50 dB (A) with damper blade position 0°.

Exact values for all parameters can be determined with our Easy Product Finder design programme.
