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 TDF ceiling swirl diffusers have fixed blades. Air discharge is horizontal radial. The supply air to room air temperature difference can be -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 TDF diffusers may also be used for extract air.

 


Nominal sizes300, 400, 500, 600, 625 mm
Minimum volume flow rate, with Δtz = -6 K10 – 42 l/s or 36 – 151 m³/h
Maximum volume flow rate, with LWA ≅ 50 dB(A)80 – 265 l/s from 288 – 954 m³/h
Supply air to room air temperature difference-12 – 10 K

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 program.

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 element

Note: The illustrations are schematic and serve to create a better understanding of the installation details.


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 as 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.
