Design Advice

Designers are often keen to select their own TBV system, however, the selection process involves many factors, so we would prefer to assist you in your selection.

  • In order to determine what type of textile ducting solution is suitable for your application, we will need to know a few things;
  • Dimensions of the space
  • The intended use of the space - from this we will calculate suitable air velocities for the occupants based on required comfort levels..
  • Permissible locations to run the textile ductwork
  • Supply air volume
  • Maximum and minimum supply temperatures and the desired room temperature
  • The required NR rating of the space
  • What type of surface we are able to mount to

Winvent3D, our inhouse design program needs all of this information to provide a quotation, we prefer not to quote per metre rates.

 

In order 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 that 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 immediately obvious when a textile based ventilation system has been dimensioned incorrectly because the ducts will be oval and "saggy" when you look at them. The difference in the static pressure between two parallel ducts could be quite considerable too. This not only has an impact on the look of the system, but also on the air distribution. If the pressure distribution is uneven it could cause draught problems below and around the duct with the highest static pressure, while in another area, the air quality will be poor where the static pressure (and therefore the volume of air) is insufficient.

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

Finally, a correctly dimensioned TBV system is important so as to achieve the required sound levels from the system.

Dialogue & Quotations


KE Fibertec has developed a number of tools and services that our customers can choose to use throughout the entire project process. Our services are graded so that customers can decide themselves which ones they require. We believe that no two jobs are the same and no solution is standard. As a result, the documentation and level of detail needs 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, while making sure that the customer's requirements are specified and documented in sufficient detail.

KE Fibertec puts a large emphasis on ensuring that the final solution is designed correctly even at the initial quotation stage. After all, it is not only about ensuring that the textile based ventilation system works properly, but also, just as importantly, that the customer's requirements have been met. This is why we ask about the system's functional requirements and the requirements for the indoor climate even at the quotation stage. We do not make a habit of selling textile ducting by the metre.

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

Detailed mounting and maintenance instructions are included. For more complicated TBV systems we also include AutoCAD drawings.

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