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 26.

Air flows on both sides of the wall.

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 where heat cannot build up or use XLT Duct Kit to remove heat 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 around the cellar door to prevent cool air leakage. For more details, see Preparing the Wine Cellar, “Door” on page 6.

Cool air drops and exits beneath door.
