  2. Atmospheric water generator - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_water_generator

    State-of-the-art AWG for home use. An atmospheric water generator (AWG), is a device that extracts water from humid ambient air, producing potable water. Water vapor in the air can be extracted either by condensation - cooling the air below its dew point, exposing the air to desiccants, using membranes that only pass water vapor, collecting fog, [1] or pressurizing the air.

  3. Evaporative cooler - Wikipedia

    en.wikipedia.org/wiki/Evaporative_cooler

    An evaporative cooler (also known as evaporative air conditioner, swamp cooler, swamp box, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from other air conditioning systems, which use vapor-compression or absorption refrigeration cycles.

    en.wikipedia.org/wiki/Water_dispenser

    A water dispenser, sometimes referred to as a water cooler (if used for cooling only), is a machine that dispenses and often also cools or heats up water with a refrigeration unit. It is commonly located near the restroom due to closer access to plumbing. A drain line is also provided from the water cooler into the sewer system.

  5. Comparison of pumps - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_pumps

    Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping ...

  6. Chiller - Wikipedia

    en.wikipedia.org/wiki/Chiller

    The liquid is drawn from the tank, pumped through the chiller and back to the tank. In industrial water chillers is the use of water cooling instead of air cooling. In this case the condenser does not cool the hot refrigerant with ambient air, but uses water that is cooled by a cooling tower. This development allows a reduction in energy ...

  7. Airwatt - Wikipedia

    en.wikipedia.org/wiki/Airwatt

    Where P is the power in airwatts, F is the rate per minute (denoted cu ft/min or CFM) and S is the suction capacity expressed as a pressure in units of inches of water. Some manufacturers choose to use the fraction 1 ⁄ 8.5 rather than the ASTM decimal, leading to a less than 0.25% variation in their calculations.
