Examples of Mis-Directed Air
Lack of proper ducting can lead to shorted
airflows. In the example at right, the supply
air projects a short distance into the room
and is drawn back into the return grille.
This leaves the exterior walls and windows
with no protection against condensation.
The DRY-O-TRON
® controller will detect
the supply air entering the return and will
erroneously conclude that the cooling and/or
dehumidification demand is completed.
In the example at right, the supply air
projects across the top of the room and is
drawn into the return grille.
This leaves the exterior walls and windows
with no protection against condensation.
The quality of the air at the pool surface
will suffer.
In the example at right, the supply air is
directed at the pool surface. The resulting
air speed at the water surface will increase
the evaporation rate. The increase may
lead to uncontrolled humidity levels.
In the example at right, having both the
supply diffusers and the return grille in the
ceiling causes a large part of the supply air
to be directed back into the return grille,
leading to unexpected operation.
A large amount of supply air is being
directed toward the pool, where it will
elevate the evaporation rate.
Only a fraction of the supply air reaches
the windows, which are the most likely
surfaces for condensation.
