Advantages
AirSox with nozzles can be applied to a wide range of applications. A system design with lots of nozzles installed per running meter makes it possible to throw the supply air a considerable distance, heating rooms with a high ceiling for example. With this type of duct we normally select a low permeability so that the majority of the supply air exits through the nozzles & reaches the occupied zone. Alternatively a duct with fewer nozzles can create local mixing & distribute the room air in the direction of the nozzles.

Function
Nozzle positions on the ducts greatly depend on the throw required & the ∆t of the supply air. For heating the nozzles are angled downwards where the less dense air travels at a lower velocity. For tempered air or cooling the nozzles can be placed horizontally or higher, the air will then exit the duct ensuring a low downward velocity. At the same time mixing is achieved in a wide area around the duct. This system design can be used very effectively when the distribution of the ducts is not ideal for the room but good air distribution is still required.

Technique
The nozzle outlet is usually a low impulse (permeable duct) outlet fitted with Ø18mm nozzles. The nozzles make it possible that this type of duct can be used for a wide range of applications whether they be cooling only, cooling & heating, heating only, or general ventilation projects.
