A FabricAir Dispersion System is customized to the specific project by in-house air engineering experts.
Optimal performance is affected by a number of factors, such as purpose of the air, room geometry, placement of duct accessories and flow models, exhaust placement, heat source placement, temperature difference (∆T), permeability of the fabric, design pressure (∆P), etc.
To determine the best design, the engineer will consider project specific factors, asking questions like what type of conditioning is supplied, and are there specific velocity requirements. These questions determine the combination of flow models that will be the best fit for the specific application.
To create the ideal air distribution in any given project, addressing its specific challenges, it is typically favorable to combine flow models. The ideal often consists of primary and secondary air flows in a combination depending on throw requirements. The primary air flow addresses the main issue. This could for example be no draft for increased comfort, or even air dispersion for an even temperature. The secondary air flow is used to ensure that no condensation builds up on the duct in humid environments.
It is of utmost importance to understand the type of space that is being designed in order to select the appropriate flow models, especially in applications that are intended to maximize occupant comfort. Flow models range from short near zones to long (directional) throws, and vary between surface and linear flows. The optimum selection and position of the flow model(s) differs for each application. Rows of flow models are placed using clock positions around the circumference of the duct.
