   www.aol.com/portable-swamp-coolers-lower-temps...

   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 ...

3. Evaporative cooler - Wikipedia

   en.wikipedia.org/wiki/Evaporative_cooler

   Porous pottery and coarse cloth maximize the area for evaporation. 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 ...

4. Evaporative cooling chambers - Wikipedia

   en.wikipedia.org/wiki/Evaporative_cooling_chambers

   Evaporative cooling chambers. Evaporative cooling chambers (ECCs), also known as "zero energy cool chambers" (ZECCs), are a type of evaporative cooler, which are simple and inexpensive ways to keep vegetables fresh without the use of electricity. Evaporation of water from a surface removes heat, creating a cooling effect, which can improve ...

5. 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.

6. Absorption refrigerator - Wikipedia

   en.wikipedia.org/wiki/Absorption_refrigerator

   An absorption refrigerator is a refrigerator that uses a heat source to provide the energy needed to drive the cooling process. Solar energy, burning a fossil fuel, waste heat from factories, and district heating systems are examples of convenient heat sources that can be used. An absorption refrigerator uses two coolants: the first coolant ...

7. Vapor-compression refrigeration - Wikipedia

   en.wikipedia.org/wiki/Vapor-compression...

   Vapour-compression refrigeration or vapor-compression refrigeration system (VCRS), [1] in which the refrigerant undergoes phase changes, is one of the many refrigeration cycles and is the most widely used method for air conditioning of buildings and automobiles. It is also used in domestic and commercial refrigerators, large-scale warehouses ...
