For your reference, the following are commonly used terms in our installation guides.
Ambient Air
The surrounding area outside the cellar such as a room, basement, garage or outdoors.
BTU/H
British Thermal Unit per Hour is a unit of heat measurement. For example, one ton of cooling equals 12,000 BTU/H
CE
Certificate of European conformity
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.
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.
CSA/ETL
Canadian Standards Association/Edison Testing Laboratory (product compliance to safety standards)
Evaporative 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.
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 to the evaporation of the refrigerant from liquid to gas phase in the coil. The Evaporator Section is connected to or inside the wine cellar.
Exhaust Air
The air leaving the evaporator or condenser section of the Wine Guardian unit.
F
(Degrees) Fahrenheit
Fan Coil Unit (Evaporator Cooling)
The fan coil unit 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 to the evaporation of the refrigerant from liquid to gas phase in the coil. The fan coil unit is ducted to or can be placed inside the wine cellar.
Flexible Duct
Round ducts with steel reinforced plastic liners, a layer of insulation and an outer plastic layer used to convey the air from the unit to the wine 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 watts transferred between the wine cellar and the ambient space. The Wine Guardian must offset this load.
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 measures. 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.
Inlet Air
The air returning from the wine room to the Wine Guardian fan coil.
I.D.
Inside diameter
Moisture
water that has been evaporated into the air.
NEC
National Electrical Code
O.D.
Outside diameter
Psig Pounds
Force per square inch gauge
Recovery
the amount of cooling or humidifying required to return the cellar to its set point temperature or humidity after some new load has been introduced, such as people in cellar or new cases of warm wine coming in.
Return/Inlet Air
the air returning from the cellar and entering the evaporator section of the Wine Guardian unit. Also the air entering the condenser section.
Set point
the desired temperature or humidity that is set on the Thermostat or Humidistat.
SP
static pressure. Unit of measurement (in inches of water column) of the pressure of the air being handled by the fan.
Supply/Discharge Air
the air leaving the Wine Guardian unit and going into the cellar from the evaporator section. Also the air leaving the condenser section.
