2. Ground-coupled heat exchanger - Wikipedia

   en.wikipedia.org/wiki/Ground-coupled_heat_exchanger

   Ground-coupled heat exchanger. A qanat and windcatcher used as an earth duct, for both earth coupling and evaporative cooling. No fan is needed; the suction in the lee of the windtower draws the air up and out. A ground-coupled heat exchanger is an underground heat exchanger that can capture heat from and/or dissipate heat to the ground.

3. Passive cooling - Wikipedia

   en.wikipedia.org/wiki/Passive_cooling

   Passive cooling covers all natural processes and techniques of heat dissipation and modulation without the use of energy. [1] Some authors consider that minor and simple mechanical systems (e.g. pumps and economizers) can be integrated in passive cooling techniques, as long they are used to enhance the effectiveness of the natural cooling process. [7]

4. 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 ...

5. Pot-in-pot refrigerator - Wikipedia

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

   A clay pot cooler filled with vegetables. 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 ...

6. Deep water source cooling - Wikipedia

   en.wikipedia.org/wiki/Deep_water_source_cooling

   Deep water source cooling. Deep water source cooling (DWSC) or deep water air cooling is a form of air cooling for process and comfort space cooling which uses a large body of naturally cold water as a heat sink. It uses water at 4 to 10 degrees Celsius drawn from deep areas within lakes, oceans, aquifers or rivers, which is pumped through the ...

7. Condenser (heat transfer) - Wikipedia

   en.wikipedia.org/wiki/Condenser_(heat_transfer)

   A condenser is designed to transfer heat from a working fluid (e.g. water in a steam power plant) to a secondary fluid or the surrounding air. The condenser relies on the efficient heat transfer that occurs during phase changes, in this case during the condensation of a vapor into a liquid. The vapor typically enters the condenser at a ...

8. Immersion cooling - Wikipedia

   en.wikipedia.org/wiki/Immersion_cooling

   Immersion cooling. Immersion cooling is an IT cooling practice by which servers are completely or partially immersed in a dielectric fluid that has significantly higher thermal conductivity than air. Heat is removed from the system by putting the coolant in direct contact with hot components, and circulating the heated liquid through heat ...

9. Water cooling - Wikipedia

   en.wikipedia.org/wiki/Water_cooling

   Water cooling is a method of heat removal from components and industrial equipment. Evaporative cooling using water is often more efficient than air cooling. Water is inexpensive and non-toxic; however, it can contain impurities and cause corrosion. Water cooling is commonly used for cooling automobile internal combustion engines and power ...
