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. Portable Swamp Coolers That Lower Temps (and Energy Costs)

   A portable swamp cooler can lower the temperature by as much as 20 degrees, but that depends on how powerful the unit is and how hot and humid the weather is. A small tabletop or cheap floor unit ...

   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]

5. Passive cooling - Wikipedia

   en.wikipedia.org/wiki/Passive_cooling

   Passive cooling is a building design approach that focuses on heat gain control and heat dissipation in a building in order to improve the indoor thermal comfort with low or no energy consumption. [1][2] This approach works either by preventing heat from entering the interior (heat gain prevention) or by removing heat from the building (natural ...

6. Cryocooler - Wikipedia

   en.wikipedia.org/wiki/Cryocooler

   Cryocooler. A refrigerator designed to reach cryogenic temperatures (below 120 K, -153 °C, -243.4 °F) is often called a cryocooler. The term is most often used for smaller systems, typically table-top size, with input powers less than about 20 kW. Some can have input powers as low as 2–3 W. Large systems, such as those used for cooling the ...

7. Vacuum cooling - Wikipedia

   en.wikipedia.org/wiki/Vacuum_cooling

   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.
