Glossary of Terms

Absolute Humidity: The mass of water vapor in a given volume of air (i.e., density of water vapor in a given parcel, usually expressed in grams per cubic meter.

Acidic: Having a pH value less than 7.

Activated Oxygen: Activated Oxygen is the linking of 3 oxygen molecules otherwise known as O3, or ozone. When the oxygen (O2) around us rises to the upper atmosphere and is exposed to the sun's ultraviolet rays, that oxygen is naturally turned into ozone (O3). This "ozone layer" protects us from the sun's harmful UV rays. Since ozone is heavier than air, it naturally falls back to earth. This is the ozone that naturally purifies our air and water. Without ozone nature could not purify the Earth.

Actual Vapor Pressure: The partial pressure exerted by the water vapor present in a parcel. Water in a gaseous state (i.e. water vapor) exerts a pressure just like the atmospheric air. Vapor pressure is also measured in millibars.

AHAM: Association of Home Appliance Manufacturers.

Air Water: Water produced from an atmospheric water generator (AWG).

Alkaline: Having a pH value greater than 7.

ANSI: American National Standards Institute.

BTU (British Thermal Unit): A BTU is the quantity of heat required to raise 1 pound of water by 1 degree Fahrenheit. This is the standard rating for compressors.

Capillary Tube: See Expansion Tube.

Chlorine: A dangerous chemical commonly used to keep tap water pure.

Compressor: The compressors basic function is to pump refrigerant throughout its closed loop of pipes and tubes. Compressors are rated in BTUs or tons. 1 Ton = 12,000 BTU.

Condensation: : The phase change of a gas to a liquid. In the atmosphere it is the change of water vapor to liquid water. Condensation commonly occurs when a vapor is cooled to a liquid, but can also occur if a vapor is compressed (i.e., pressure on it increased) into a liquid, or undergoes a combination of cooling and compression. This is the opposite process of evaporation

Condenser Coil: A series of metal tubes similar to a radiator in an automobile. Condensers are used to change the state of refrigerant from a gas to a liquid by cooling the hot gas until it changes state.

Dehumidification Process: The compressor pumps refrigerant throughout its closed loop of pipes and tubes, it compresses the vapor refrigerant, raising the temperature of the refrigerant above the outside ambient air temperature. When the cooler outside air is blown through the system's condenser coils by the fan, the heat exchange process leads to the refrigerant changing state from a vapor to a liquid. The now chilled liquid refrigerant is pumped through evaporator coil, which becomes colder than the ambient air. This creates a dew-point and moisture can then be collected off of the evaporator coil. In an AWG machine the water is then purified and stored until it is consumed.

Dew-Point: The temperature at which ambient air will lose its moisture.

Dissolved Oxygen: The amount of oxygen dissolved in a body of water as an indication of the degree of health of the water and its ability to support a balanced aquatic ecosystem; also, the amount of free (not chemically combined) oxygen dissolved in water, wastewater, or other liquid, usually expressed in milligrams per liter, parts per million or percent of saturation; abbr.

Distilled Water: Water from which impurities such as dissolved salts and colloidal particles have been removed by one or more processes of distillation; chemically pure water.

Dry Bulb Temperature: The actual air temperature. See wet bulb temperature below.

Electrostatic: : When two objects in the vicinity of each other have different electrical charges, an electrostatic field exists between them. An electrostatic field also forms around any single object that is electrically charged with respect to its environment. An object is negatively charged (-) if it has an excess of electrons relative to its surroundings. An object is positively charged (+) if it is deficient in electrons with respect to its surroundings.

Evaporation: The phase change of liquid water into water vapor. This is the process whereby atoms or molecules in a liquid state gain sufficient energy to enter the gaseous state. It is the opposite process of condensation.

Evaporator Coil: A series of metal tubes similar to a radiator in an automobile. Evaporators are used to change the state of refrigerant from a liquid to a cold low pressure gas.

Expansion Tube: A small diameter tube connecting the condenser coil and evaporator coil which facilitates the refrigerants change of state from a liquid to a gas.

FLA: The full load amps or the amperage the motor will draw if it is doing its rated horsepower worth of work.

Freezing: The phase change of liquid water into ice.

Freon: See HFC Refrigerant

HFC Refrigerant: These refrigerants are made of Hydrogen, Fluorine and Carbon, none of which will damage the ozone layer. The most popular are 134A, 407C and 410A.

How AWGs Work: See dehumidification process.

Humidity: In hydrometrical reports, complete saturation of the air with moisture is designated by a humidity level of 100. Partial saturation is noted by smaller numbers. See Absolute and Relative Humidity.

Inorganic Minerals: Common minerals found in the ground: your body is unable assimilate these minerals. Often found in ground water an excess of these minerals can lead to serious health problems.

Live Water: Water that is fully oxygenated. It cannot carry any more oxygen.

LRA: The current drawn by a motor which is locked and cannot rotate. This occurs instantly during start up.

MCC: Maximum continuous current or the minimum �rated load amp� value that may be used to comply with U.L. and N.E.C. requirements which the motor compressor protection system will not permit a continuous current in excess of 156% of the rated load amp.

Melting: The phase change of ice into liquid water.

Mixing ratio: The mass of water vapor in a parcel divided by the mass of the dry air with in that parcel (not including water vapor)

Multi Trace Minerals: Micro-minerals or trace elements to include amounts of iron, cobalt, chromium, copper, iodine, manganese, selenium, zinc, and molybdenum. These are dietary minerals needed by the human body in very small quantities (generally less than 100mg/day) as opposed to macro-minerals which are required in larger quantities. Note that the use of the term "mineral" here is distinct from the usage in the geological sciences.

Organic Minerals: Organic minerals are minerals created by plants from inorganic minerals. Your body needs Organic minerals for nourishment. We get them by eating plants or animals.

Oxygenate: To treat, combine, or enrich with oxygen.

PH: The symbol for the logarithm of the reciprocal of hydrogen ion concentration in gram atoms per liter, used to express the acidity or alkalinity of a solution on a scale of 0 to 14, where 7 is neutral, less than 7 represents acid, and more than 7 alkaline.

Precipitation: The condensation of a solid from a solution during a chemical reaction; rain, snow and other forms of water falling from the sky.

Potable Water: Water that is safe to drink.

R.O. Water: Water from Reverse Osmosis. Process in which pure water is produced by forcing waste or saline water through a semi-permeable membrane.

Refrigerant: See HFC Refrigerant

Relative Humidity (RH): The amount of water vapor actually in the air divided by the amount of water vapor the air can hold. Relative humidity is expressed as a percentage and can be computed in a variety of ways. One way is to divide the actual vapor pressure by the saturation vapor pressure and then multiply by 100 to convert to a percent.

RLA: The maximum current a compressor should draw under any operating conditions.

Saturation Of Air: The condition under which the amount of water vapor in the air is at the maximum possible for the existing temperature and pressure. Condensation or sublimation will begin if the temperature falls or water vapor is added to the air.

Saturation Vapor Pressure: The maximum partial pressure that water vapor molecules will exert if the air were saturated with vapor at a given temperature. Saturation vapor pressure is directly proportional to the temperature.

Specific Humidity: The mass of water vapor in a parcel divided by the total mass of the air in the parcel (including water vapor).

Stabilized Oxygen: Also know as Aerobic Oxygen, it is a safe, non-toxic stabilized liquid concentrate of electrolytes of oxygen.

Sterilize: To destroy microorganisms in or on, usually by bringing to a high temperature with steam, dry heat, or boiling liquid.

Sublimation: In U.S. meteorology, the phase change of water vapor in the air directly into ice or the chance of ice directly into water vapor. Chemists, and sometimes meteorologists, refer to the vapor to solid phase change as "deposition."

TDS (Total Dissolved Solids): Total dissolved solids is an expression for the combined content of all inorganic and organic substances contained in a liquid which are present in a molecular, ionized or micro-granular (colloidal sol) suspended form.

Transpiration: Transpiration is the evaporation of water from aerial parts of plants, especially leaves but also stems, flowers and fruits.

Ultra-Filter: Is a manufactured hollow-fiber membrane based on a nominal pore size of approximately 0.01 micron, and is made of modified Polyethersulfone (PES), a hydrophilic, chemically stable polymer capable of withstanding aggressive environments often present in water and fluid treatment situations.

Ultra Violet: Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than soft X-rays. It can be subdivided into near UV (400�200 nm wavelength; abbrev. NUV), far or vacuum UV (200�10 nm; abbrev. FUV or VUV), and extreme UV (1�31 nm; abbrev. EUV or XUV).

Water Cycle: The cycle of evaporation and condensation that controls the distribution of the earth's water as it evaporates from bodies of water, condenses, precipitates, and returns to those bodies of water. Also called hydrologic cycle.

Wet Bulb Temperature: The lowest temperature that can be obtained by evaporating water into the air at constant pressure. The name comes from the technique of putting a wet cloth over the bulb of a mercury thermometer and then blowing air over the cloth until the water evaporates. Since evaporation takes up heat, the thermometer will cool to a lower temperature than a thermometer with a dry bulb at the same time and place. Wet bulb temperatures can be used along with the dry bulb temperature to calculate dew point or relative humidity.
