Nozzle Fabric Ducts

Here is a type of fabric air duct (textile air duct, Air Sox Duct, Air Duct Sox, Air Sock Duct, Air Duct Sock) called Nozzle Duct.  Read more about its advantages, functions and technique below.

NOZZLE DUCTS

  • Advantages
    Nozzle air sox ducts 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 textile air 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 textile air duct with fewer nozzles can create local mixing and distribute the room air in the direction of the nozzles.
  • Function
    Nozzle positions on the fabric air ducts greatly depend on the throw required and 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 sock duct ensuring a low downward velocity. At the same time mixing is achieved in a wide area around the fabric 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 air duct) outlet fitted with Ø18mm nozzles. The nozzles make it possible that this type of air sock duct can be used for a wide range of HVAC ductwork applications whether they are cooling only, cooling and heating, heating only, or general ventilation project.
