Directory of Terms

Ambient Air – The surrounding area outside the cellar such as a room, basement, garage or outside.
BTU/H – British Thermal Unit per Hour is a unit of heat measurement. For example, one ton of cool-
ing equals 12,000 BTU/H.
CFM – Cubic feet per minute. A unit of measurement for the amount of air handled by the fan.
Cellar – The wine storage area being conditioned by the Wine Guardian unit.
Condensate / Condensation – The water formed out of the air when it is cooled below a certain
temperature (called dew point). Often referred to as "sweating" on pipes and cold surfaces. This
water collects at the bottom of the evaporator or cooling coil and drains out of the unit through the
drain line.
Condenser (heat rejection) Section / Coil – The Condenser Section uses the compressor, condenser
coil and fan to remove heat from the refrigerant to the ambient air outside the wine cellar. The word
condenser refers to the condensation of the refrigerant from gas to liquid phase.
Exhaust Air – The air leaving the evaporator or condenser section of the Wine Guardian unit.
Evaporator (cooling) Section / Coil – The Evaporator Section uses the cooling coil and the fan to remove
heat from the air inside the wine cellar to the refrigerant, cooling the air and condensing moisture out of the
air. The word evaporator refers the evaporation of the refrigerant from liquid to gas phase in the coil. The
Evaporator Section is connected to or inside the wine cellar.
Flexible Duct – Round ducts with a steel reinforced plastic liner, a layer of insulation and an outer plastic
layer used to convey the air from the unit to the cellar or ambient space.
Grille or Diffuser – Inlet or outlet plates to direct the airflow or protect the inside of the unit.
Heat Gain / Loss – The amount of cooling or heating expressed in BTU/H tranferred between the
wine cellar and the ambient space. The Wine Guardian must offset this load.
Inlet Air – The air entering the evaporator and condenser sections of the Wine Guardian unit.
Recovery – The amount of cooling the unit does to return the cellar to its set point temperature after some
new load is introduced, such as people or new cases of warm wine in the cellar.
Return Air - The air leaving the cellar and returning to the inlet of the evaporator coil.
SP – Static pressure. Unit of measurement ( inches of water column) of the pressure of the air handled by
the fan.
Set Point – The desired temperature or humidity set on the thermostat or humidistat.
Supply Air - The air entering the cellar from the discharge of the evaporator coil.
