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.
The position of the guide vanes of the VD series ceiling swirl diffusers can be adjusted. The ability to change the direction of air flow ensures operation in heating and cooling modes or when changing the air flow range. Horizontal air supply is carried out in all directions. Vertical air supply is possible in heating mode. The temperature difference between the supply air and the room can range from –12 to +15 K.
The drive (optional) adjusts the position of the blades if necessary.
