Directory of terms
• Ambient Air – The surrounding air outside the cellar such as a room, basement,
garage or outdoors.
• CFM – Cubic feet per minute. A unit of measurement for the amount of air
handled by the fan.
• CLS – Cubic liters per second. A unit of measurement for the amount of air
handled by the fan.
• CE – Certificate of European conformity
• CSA/ETL – Canadian Standard Association/Electric Testing Laboratory
• Drip Pad – the wire mesh pad inside the humidifier that becomes coated with
water as the water drips down by gravity. Air being drawn over the pad by a fan
causes the water to evaporate into the air, increasing its moisture content.
• Grille or Diffuser – Inlet or outlet plates to direct the airflow or protect the inside
of the unit.
•
Humidistat – an electrical instrument that measures the relative humidity of air
and reads in percent (%).
•
Humidity – relative humidity is the percentage of moisture in the air relative to
the maximum amount of moisture the air could hold at any particular condition.
Relative humidity is what is most widely used and is what a humidistat measure.
For example, 100% relative humidity means the air has as much moisture as it
can possibly hold at that temperature. Absolute or specific humidity is the specific
amount of moisture (usually measured in grains of moisture per point of air) in
the air at a given air condition
•
Moisture – water that has been evaporated into the air.
• NEC – National Electrical Code
•
Set point – the desired temperature or humidity that is set on the Thermostat or
Humidistat
•
UL – Underwriters Laboratory
General Overview
The Wine Guardian Humidifier is a self-contained unit designed specifically for wine
cellars. It has been designed for easy installation and operation, either as a freestanding
unit or mounted on a Wine Guardian cooling unit. Wine Guardian uses a humidistat to
sense and control the amount of moisture needed to be added to the cellar. Humidifiers
are not intended to remove moisture, only add moisture. All components are of a high
quality, standard commercial grade. The humidifier, depending upon model, operates
with 24-volt power or digital signal from the Wine Guardian control panel, and therefore
does not require UL or CSA approval. All wiring complies with NEC.
Wine Guardian Humidifiers are the evaporative drip pad-type. Air from the cellar is
drawn over a distribution pad that is saturated with water from a distribution tray. As the
air passes through the pad, it absorbs moisture through evaporation of the water. This
raises the humidity of the leaving air that returns to the cellar. Warm water is
recommended for use with the humidifier (105°F - 40°C max.), however the system will
work using cold water though with reduced efficiency. Warm water increases the
capacity of the humidifier to evaporate the water as it passes through the pad. The
