Deep water source cooling is very energy efficient, requiring only 1/10 of the average energy required by conventional cooler systems. [1] Consequently, its running costs can also be expected to be much lower.
In the United States, the use of the term swamp cooler may be due to the odor of algae produced by early units. [5] Externally mounted evaporative cooling devices (car coolers) were used in some automobiles to cool interior air—often as aftermarket accessories [6] —until modern vapor-compression air conditioning became widely available.
Water is inexpensive, non-toxic, and available over most of the earth's surface.Liquid cooling offers higher thermal conductivity than air cooling. Water has unusually high specific heat capacity among commonly available liquids at room temperature and atmospheric pressure allowing efficient heat transfer over distance with low rates of mass transfer.
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. Find the best room-size portable swamp ...

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.
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 ...
