Airflow & Ventilation

Airflow and ventilation are two of the most important criteria for the proper operation of your WhisperKOOL
cooling unit ensuring a stable, functional wine cellar environment. Please review the following five
guidelines prior to installing your WhisperKOOL cooling unit..

1) Airflow - Required Clearance

Proper airflow is critical to the performance of the
WhisperKool unit. Any obstruction to the intake and
exhaust ports on both sides on the unit will compromise
the unit’s ability to cool. Make sure the Whisperkool unit
air vents are clear. Check the front and rear air intake
vents for any possible obstruction. There should be a
clearance of three feet directly in front of the intake and
exhaust vents.

2) WhisperKOOL Airflow - Bascis

3) Exhaust Room Ventilation Requirements

The WhisperKOOL unit provides cool air into the wine
cellar at a 45˚ degree downward angle, thereby cooling
the cellar’s room temperature. The unit must be mounted
high in the room in order to capture the warmer air that
rises up in the cellar.

Heated air is released through the back of the unit into the
exhaust room. WhisperKOOL units have been designed to
maintain up to a 30˚ degree temperature differential.

To maintain 55˚ degrees in the wine cellar, the temperature
in the exhaust room must not rise above 85˚ degrees.

Proper ventilation of the WhisperKool unit in the exhaust
room 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 on
the exhaust side. This heat needs to dissipate freely away
from the unit for the WhisperKOOL to function properly.

The exhaust room requires both, an exhaust fan mounted
near the top of the room, and an air intake near the
bottom of the room. The exhaust fan is needed to draw out
the warmest air, while the air intake allows cooler air to
enter, enabling air circulation. Without both the exhaust
fan and air intake, the warm air will be locked inside the
room resulting in increasing temperatures.

Without both the exhaust fan and air intake the warm air
will be locked in the exhaust room, resulting in rising room
temperatures. With the maximum 30˚ degree temperature

rential provided by the WhisperKOOL unit, this will
result in proportionally increasing temperatures in the
wine cellar. For example, if the exhaust room is allowed
to increase its temperature to 95˚ F, then the wine cellar
can only be cooled to 65˚ F.

As a result your WhisperKOOL unit will end up running
continuously , which can lead to icing and other problemns,
including premature failure.

Venting the WhisperKOOL unit through an exterior wall is
possible, though not recommended. Installation through
an outside wall can be considered when all of the following
conditions are met:

1) The outside temperature does not exceed 85˚ degrees in
the summer

2) The temperature stays above 40˚ degrees in the winter

3) The exposed back part of the cooling unit is protected

(cellar wall)

from direct sunlight and rain
(Vintage Cellars provides an optional outside cover)

Note: if outside ambient temperatures rise above 85 ˚
degrees, the temperature in the cellar will increase by
a parallel amount., This results in the unit running
continuously, which can lead to icing and other problems
including premature failure.

When the outside temperature falls below 40˚ degrees,
unit will ice up on the inside, risking premature failure.
