   A portable evaporative cooler, also called a swamp cooler, is an affordable alternative to a portable or window air conditioner if you live in a dry climate. ... A big space like a garage, studio ...

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.

4. Pot-in-pot refrigerator - Wikipedia

   en.wikipedia.org/wiki/Pot-in-pot_refrigerator

   A pot-in-pot refrigerator, clay pot cooler [1] or zeer (Arabic: زير) is an evaporative cooling refrigeration device which does not use electricity. It uses a porous outer clay pot (lined with wet sand) containing an inner pot (which can be glazed to prevent penetration by the liquid) within which the food is placed.

5. Evaporative cooling chambers - Wikipedia

   en.wikipedia.org/wiki/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 vegetable storage shelf life.

6. Absorption refrigerator - Wikipedia

   en.wikipedia.org/wiki/Absorption_refrigerator

   The expansion valve partially vaporizes the refrigerant cooling it via evaporative cooling and the resulting vapor is cooled via expansive cooling. (This is a combination of Joule-Thomson cooling and work done by the expanding gas, both at the expense of the internal energy of the gas) The cold, low pressure liquid refrigerant will now absorb ...

7. Chiller - Wikipedia

   en.wikipedia.org/wiki/Chiller

   A liquid (glycol based) chiller with an air cooled condenser on the rooftop of a medium size commercial building. In air conditioning systems, chilled coolant, usually chilled water mixed with ethylene glycol, from a chiller in an air conditioning or cooling plant is typically distributed to heat exchangers, or coils, in air handlers or other types of terminal devices which cool the air in ...
