Principles of FlowModels
It is rarely possible to "see" air flow
patterns in a conditioned space unless
smoke is added to the supply air; this
makes it extremely difficult to predict the
required flow model for a new project.
With our 6 new FlowModels which can be
combined with the 6 FabricAir® fabrics in
a broad range of air distribution possibili- |
ties, we no longer have to rely on guess-
work. Using an extensive number of CFD
simulations we have generated a thumbnail
sketch of the general airflow for eachu
FlowModel. You can find these described
on this page including a brief explanation
of the thermodynamic and ventilation
principles. These should be used for
preliminary selection of the required space
flow characteristic. |
