Description

Ceiling swirl diffusers in air conditioning systems create a vortex supply of air for good mixing with the room air. The air flow obtained at the outlet of the diffuser allows one to achieve high ejection values, thereby quickly reducing the flow rate and leveling out the temperature difference between the supply air and the air in the room. Ceiling swirl diffusers are used for high air flows. As a result, there is a mixing of air flows in comfort zones, with a good distribution of air jets throughout the room and a small turbulent vortex in the area where people are present. Ceiling swirl diffusers of the AIRNAMIC series are made with fixed guide lamellas with a 3D profile. This creates a high air flow rate with a low sound power level. The temperature difference between the supply air and the room can vary from – 10 to +10 K. The damper blade for balancing the air flow simplifies operation. To create an attractive, holistic room design, AIRNAMIC series diffusers can also be used for exhaust ventilation. In this case there is no flow equalizer.
