2. Evaporative cooler - Wikipedia

   en.wikipedia.org/wiki/Evaporative_cooler

   A misting fan may be used outdoors, especially in a dry climate. It may also be used indoors. Small portable battery-powered misting fans, consisting of an electric fan and a hand-operated water spray pump, are sold as novelty items. Their effectiveness in everyday use is unclear.

3. Cooling tower - Wikipedia

   en.wikipedia.org/wiki/Cooling_tower

   The water is sprayed through pressurized nozzles near the top of the tower, and then flows downward through the fill, opposite to the air flow. Advantages of the counterflow design: Spray water distribution makes the tower more freeze-resistant. Breakup of water in spray makes heat transfer more efficient. Disadvantages of the counterflow design:

4. Spray pond - Wikipedia

   en.wikipedia.org/wiki/Spray_pond

   Specific spray pond surface areas tend to range between 1.2 and 1.7 m 2 per m 3 /h of water to be cooled. The width chosen for a drift channel around the active zone of the pond (containing the sprays) is dependent on a number of factors, including the prevailing wind strength, the average size of the spray droplets produced by the nozzles, and the presence of any nearby structures which may ...

5. 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 ...

6. Fan (machine) - Wikipedia

   en.wikipedia.org/wiki/Fan_(machine)

   A household electric fan A large cylindrical fan. A fan is a powered machine that creates airflow. A fan consists of rotating vanes or blades, generally made of wood, plastic, or metal, which act on the air. The rotating assembly of blades and hub is known as an impeller, rotor, or runner. Usually, it is contained within some form of housing ...

   At the 2.05 MW Ashford A power station Kent, UK, cooling water for the oil-fired engines was obtained from, and returned to, cooling water ponds. [11] The principal cooling mechanism in the ponds was by convection from the water surface. At the 89 MW Back o’ the’ Bank power station in Bolton UK the cooling water was cooled in 4 spray ponds ...
