Ventilation
Proper ventilation of the WhisperKOOL
unit is one of the most important and
often overlooked issues associated with
the unit’s performance.The WhisperKOOL
unit does create a large amount of heat,
which needs to dissipate away from the
unit freely in order to cool correctly. This
issue is sometimes overlooked for several
reasons:
1.) If there is inadequate ventilation on
the rear side of the unit, this will
result in further heat buildup and will
cause it to recirculate the hot air near
the ceiling on the exhaust side of the
unit, therefore limiting the ability to
cool the room.
2.) Even though the space may seem to be
adequate, the heat needs to be able to
dissipate away from the unit. A lack of
ventilation and air circulation will
cause the room to become extremely
warm.
3.) The WhisperKOOL unit is designed to
cool 30°F cooler than the ambient
temperature of the room it is
exhausting the hot air to (rear side of
unit). This means that in order to
maintain an optimum temperature of
55°F, the temperature on the exhaust
side of the WhisperKOOL unit cannot
be more than 85°F.

In order to determine if ventilation may be
the problem, try the following tests listed
on page 25.
If the exhaust area is confined, (for
example, if the unit vents into a
crawlspace), then as the temperature
outside the unit rises, the WhisperKOOL
unit must expend more energy (and will
generate more heat) in order to maintain a
cool temperature inside the room.
Eventually, the unit cannot keep up and the
temperature inside the cellar climbs.
To solve the problem, make sure that the
WhisperKOOL vents into a space of the
same size or larger where heat cannot
build up.
Door Seal
A high quality door with a proper seal is
another important aspect of a well-
designed cellar. If there is a gap between
the bottom of the door and the floor, the
cool air will sink and flow out beneath the
door. While the release of the cool air may
be subtle, it will require the
WhisperKOOL unit to continue to operate
without achieving the desired results. Use
good-quality weather-stripping and seals
