  2. Evaporative cooler - Wikipedia

    en.wikipedia.org/wiki/Evaporative_cooler

    In extremely dry climates, evaporative cooling of air has the added benefit of conditioning the air with more moisture for the comfort of building occupants. The cooling potential for evaporative cooling is dependent on the wet-bulb depression, the difference between dry-bulb temperature and wet-bulb temperature (see relative humidity).

    The sound is generated by the impact of falling water, by the movement of air by fans, the fan blades moving in the structure, vibration of the structure, and the motors, gearboxes or drive belts. Approach – The approach is the difference in temperature between the cooled-water temperature and the entering-air wet bulb temperature (twb ...

  5. Air conditioning - Wikipedia

    en.wikipedia.org/wiki/Air_conditioning

    Unlike other types of air conditioners, evaporative coolers rely on the outside air to be channeled through cooler pads that cool the air before it reaches the inside of a house through its air duct system; this cooled outside air must be allowed to push the warmer air within the house out through an exhaust opening such as an open door or window.

  6. Fan (machine) - Wikipedia

    en.wikipedia.org/wiki/Fan_(machine)

    The cross-flow or tangential fan, sometimes known as a tubular fan, was patented in 1893 by Paul Mortier, [17] [18] and is used extensively in heating, ventilation, and air conditioning (HVAC), especially in ductless split air conditioners. The fan is usually long relative to its diameter, so the flow remains approximately two-dimensional away ...

    en.wikipedia.org/wiki/Air_cooling

    Air cooling is a method of dissipating heat. It works by expanding the surface area or increasing the flow of air over the object to be cooled, or both. An example of the former is to add cooling fins to the surface of the object, either by making them integral or by attaching them tightly to the object's surface (to ensure efficient heat ...
