Maintenance
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 sizes | 300, 400, 500, 600, 625 mm |
| Minimum volume flow rate, with Δtz = -6 K | 10 – 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 |
