Design Guide

To be able to dimension a textile based ventilation system, it is important to understand a number of essential parameters and concepts. A textile based ventilation system is not fundamentally different from conventional ventilation systems, but there are a number of key points where it is important to be extra cautious, such as pressure conditions, pressure loss, pulsations, pressure impact, entrainment, air velocities and sound.

It is very obvious when a textile based ventilation system has been dimensioned incorrectly because the ducts will be oval and "sagging" when you look at them. The difference in the static pressure between two parallel ducts may be quite considerable too. This not only has an impact on the aesthetic impression, but also on air distribution to a great extent. If the pressure distribution is inappropriately uneven this can cause draught problems below and around the duct with the highest static pressure, while in the opposite case, the air quality will be poor in the area where the static pressure (and therefore the volume of air) is not sufficient.

Further, there may be a risk of pulsations in the textile material that may damage not only the textile material but also the suspension material.

Design and flow visualization with TBV Designer

KE Fibertec has developed the TBV Designer program in order to be able to document technical data supported by know-how.

The program enables flow visualizations and documentation of the solution. It also features freedom of design, spatiality, and information on velocity within the occupied zone height.

You can also design and calculate textile ducts directly in the MagiCAD Ventilation product database. 



Dialogue & Quotations

KE Fibertec has developed a number of tools and services which our customers can choose to use throughout the entire project process. Our services are graded so that customers can decide themselves which ones they do and don't want. Our opinion is that no two jobs are the same and no solution is standard. Consequently, the documentation and level of detail need to be adapted to the requirement and each individual project.

Our service can be split into two categories:

  • Quotation and design
  • Exteneded project documentation

Our quotation and design processes are described in detail in our ISO 9001 quality assurance system. This ensures that we prepare the basis for the quotation and the quotation itself according to the standardised guidelines, making sure that the customer's requirements are specified and documented in sufficient detail.

KE Fibertec puts large emphasis on ensuring that the final solution is designed correctly even at the quotation stage. After all, it is not only about ensuring that the textile based ventilation system works properly, but also, to just as large extent, that the customer's indoor climate requirements have been met. This is why we ask about the system's functional requirements and the requirements for the indoor climate at the quotation stage.

All the calculations are proven using our unique software WinVent 3D, which is offered to all our customers, regardless of the size of their project and, of course, free of charge.

Of course detailed mounting and maintenance instructions are included. For complicated TBV systems we also include AutoCad drawings.

As part of our extended project documentation we offer full-scale measurements in our laboratory, on-site measurements and CFD simulations.
