Do place diffusers as
close to the cold
surface as possible,
preferably within 12
inches (25 mm).
Do
direct the air at the
sharpest angle possible
so the air will follow the
surface. See “Coanda
Effect” in ASHRAE
Fundamentals.
Direct 3 - 5 CFM of supply air per square foot (15 - 26 l/s per square meter) of glass to all exterior
windows and doors, or other surfaces that might reach dew point.
Do not direct
supply air at a wide
angle to the
surface. Larger
surfaces (like win-
dows) will not be
completely covered.
Do not use long throws.
The resulting supply air
mixed with room air will
not prevent the windows
from sweating.
Unless special
arrangements were
made at time of sale,
do not blow air directly
at a pool. Doing so
can increase the evap-
oration rate drastically.
Never position a supply diffuser such
that supply air will be drawn into the
return grille. Doing so may result in
erroneous sensor readings and mode
oscillation.
