Rigid duct / Semi-flexible duct / Flexible duct

These options allow the insertion of rigid, semi-flexible and flexible air ducts, respectively.

When entering a duct, the following parameters must be specified:

• Reference
• Type of duct
  • Rectangular, custom (only for “Rigid ducts”) / Rectangular section / Circular section
• Catalogue selection
  • Catalogue
  • Material
  • Selection
• Duct dimensions
  • Width x Height (only for “Rectangular, custom”)

Data can be selected and imported from the "Manufacturer catalogues" or the "Library of generic elements" using the assistant available on the right-hand side of the program.

Library of generic elements

In the "Library of generic elements" option, in the "Project" group, generic duct libraries can be created and edited.

The data associated with each type of duct, regardless of whether they are rigid, semi-flexible or flexible, is as follows:

• Reference
• Description
• Roughness coefficient
• Rectangular ducts, custom
  • Reference
  • Thickness
• Rectangular ducts
  • Reference
  • Height
  • Width
  • Thickness
• Circular ducts
  • Reference
  • Diameter
  • Thickness

Duct ends must be connected to other ducts, or ventilation unit or air terminal must be incorporated into the ducts.

If the entire ductwork system has terminal elements and is closed at all ends except one, a "Initial point of the duct pre-installation" must be provided at that end (available in the "Equipment" menu of the "Air distribution" group) so that the program interprets this situation and does not require the addition of a supply air machine.

In the design process, the program analyses the layout and connections of the installation. It categorises the ducts as "Supply air (SUP)" (blue), "Discharge air (EHA)" (red), "Exhaust air (ETA)" (yellow) or "Outdoor air (ODA)" (green) and displays them with the colour that determines their category. This category can also be seen in the information text that appears when hovering over each duct.
