  2. 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.

  3. Vacuum drying - Wikipedia

    en.wikipedia.org/wiki/Vacuum_drying

    Vacuum dryer is the equipment with the help of which vacuum drying is carried out. Vacuum dryers are sometimes made up of cast iron, but most are made of stainless steel, so that they can bear the high vacuum pressure without any kind of deformation. The oven is divided into hollow trays which increases the surface area for heat conduction. The ...

    en.wikipedia.org/wiki/Drying

    Laundry hung on a clothes line in a drying room (dehumidifier in the background and duct for ventilation in the ceiling). Drying is a mass transfer process consisting of the removal of water or another solvent [1] by evaporation from a solid, semi-solid or liquid.

    Warm air systems distribute the heated air through ductwork systems of supply and return air through metal or fiberglass ducts. Many systems use the same ducts to distribute air cooled by an evaporator coil for air conditioning. The air supply is normally filtered through air filters [dubious – discuss] to remove dust and pollen particles. [15]

  6. Passive cooling - Wikipedia

    en.wikipedia.org/wiki/Passive_cooling

    The effectiveness of evaporative cooling is largely dependent on the humidity of the outside air; dryer air produces more cooling. A study of field performance results in Kuwait revealed that power requirements for an evaporative cooler are approximately 75% less than the power requirements for a conventional packaged unit air-conditioner. [31]

    Demonstration of evaporative cooling. When the sensor is dipped in ethanol and then taken out to evaporate, the instrument shows progressively lower temperature as the ethanol evaporates. Rain evaporating after falling on hot pavement. Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. [1]

    A typical evaporative, forced draft open-loop cooling tower rejecting heat from the condenser water loop of an industrial chiller unit Natural draft wet cooling hyperboloid towers at Didcot Power Station (UK) Forced draft wet cooling towers (height: 34 meters) and natural draft wet cooling tower (height: 122 meters) in Westphalia, Germany Natural draft wet cooling tower in Dresden (Germany)

  9. Vacuum cooling - Wikipedia

    en.wikipedia.org/wiki/Vacuum_cooling

    Vacuum cooling is a rapid cooling technique for any porous product that has free water and uses the principle of evaporative cooling.Vacuum cooling is generally used for cooling food products that have a high water content and large porosities, due to its efficacy in losing water from both within and outside the products.
