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. Deep water source cooling - Wikipedia

   en.wikipedia.org/wiki/Deep_water_source_cooling

   The thermodynamic efficiency of the overall system can be improved by utilizing evaporative cooling, where the temperature of the cooling water is lowered close to the wet-bulb temperature by evaporation in a cooling tower. This cooled water then acts as the heat sink for the heat pump.

4. Automotive air conditioning - Wikipedia

   A car cooler. A car cooler is an automobile evaporative cooler, sometimes referred to as a swamp cooler. [32] [33] Most are aftermarket relatively inexpensive accessories consisting of an external window-mounted metal cylinder without moving parts, but internal under the dashboard or center floor units with an electric fan are available.

5. 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 ...

6. Water cooling - Wikipedia

   en.wikipedia.org/wiki/Water_cooling

   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.

7. Absorption refrigerator - Wikipedia

   en.wikipedia.org/wiki/Absorption_refrigerator

   Common absorption refrigerators use a refrigerant with a very low boiling point (less than −18 °C (0 °F)) just like compressor refrigerators.Compression refrigerators typically use an HCFC or HFC, while absorption refrigerators typically use ammonia or water and need at least a second fluid able to absorb the coolant, the absorbent, respectively water (for ammonia) or brine (for water).
