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 sur-
face. 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 perpendi-
cular to the surface.
Larger surfaces
(like windows) 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
evaporation rate.
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.
