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 TDV ceiling swirl diffusers have adjustable air control blades. The air pattern can be adjusted to meet different local requirements. Horizontal air discharge is one-way, two-way or omni directional. Vertical air discharge is possible but only for heating. The supply air to room air temperature difference may range from –12 to +10 K.

A damper blade (optional) simplifies volume flow rate balancing for commissioning. Pressure tap and cord-operated damper blade (optional) allow for volume flow rate balancing with the diffuser face in place.

To give rooms an aesthetic, uniform look, Type TDV diffusers may also be used for extract air. Air control blades are not required for extract air applications.

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.

Installation in T-bar ceilings

Flush ceiling installation with square plenum box

① Duct
② Suspension hole
③ Diffuser face

Horizontal duct connection
Four suspension holes
Suspension with cords, wires or hangers, to be provided by others

Installation and commissioning

Preferably for rooms with a clear height up to 4.0 m
Flush ceiling installation
Freely suspended installation only with an extended border (supply air variant)
Horizontal or vertical duct connection
If necessary, carry out volume flow rate balancing with the damper blade

These are only schematic diagrams to illustrate installation details.

AK-Uni-...-MN Volume flow rate balancing

① Damper blade
② White cord for opening the damper blade

Open, 0°

Volume flow rate balancing

When several diffusers are connected to just one volume flow controller, it may be necessary to balance the volume flow rates.

Ceiling diffusers with universal plenum box and damper blade (variant -M): The diffuser face can be removed to access the damper blade; the damper blade can then be set to any position between 0 and 90°
Ceiling diffusers with universal plenum box, damper blade and pressure tap (variant -MN): The diffuser face need not be removed since the damper blade can be set with two cords (white and green).

Volume flow rate measurement

Ceiling diffusers with universal plenum box, damper blade and pressure tap (variant -MN) allow for volume flow rate balancing even with the diffuser face in place.

Connect the measuring tube to the digital manometer
Read the effective pressure
Read the volume flow rate off the characteristic or calculate it
If necessary, adjust the damper blade position with the cords

A characteristic is included with each AK-Uni plenum box.
