Maintain optimal wine cellar humidity – even in the most humid climates.
Cooling a wine room in humid climates takes extra care.
First and foremost, it is extremely important to build the wine room with a good vapor barrier. Without it, excessive moisture in the ambient air can and will find its way into the wine room. Relative humidity above 70% RH can cause labels to peel and mold to grow – both undesirable conditions for wine collectors. The wine cellar cooling unit should have a controller that provides humidity read out and high humidity alarm functions so that it can be monitored similar to temperature readings.
The wine cellar cooling unit you install should also be manufactured with a cooling coil that will remove excess moisture from the space as a part of the cooling process when the wine room relative humidity is above 70% RH. This moisture removal process should be automatic without having to change fan speeds to achieve the desired results. The wine cooling unit should also be sized appropriately for the space, with specific attention to unit run time, as it may need to run for longer periods in order to properly dehumidify the air.
