2. Evaporative cooler - Wikipedia

   en.wikipedia.org/wiki/Evaporative_cooler

   The cooling potential for evaporative cooling is dependent on the wet-bulb depression, the difference between dry-bulb temperature and wet-bulb temperature (see relative humidity). In arid climates , evaporative cooling can reduce energy consumption and total equipment for conditioning as an alternative to compressor-based cooling.

3. Wet-bulb temperature - Wikipedia

   en.wikipedia.org/wiki/Wet-bulb_temperature

   The wet-bulb temperature is the lowest temperature that may be achieved by evaporative cooling of a water-wetted, ventilated surface.. By contrast, the dew point is the temperature to which the ambient air must be cooled to reach 100% relative humidity assuming there is no further evaporation into the air; it is the temperature where condensation (dew) and clouds would form.

   Cool-Space 400 Evaporative Swamp Cooler. If you need to cool down an especially large area, like a warehouse, workshop garage, or studio, consider this beast. Boasting a 36-inch diameter fan, the ...

5. Passive cooling - Wikipedia

   en.wikipedia.org/wiki/Passive_cooling

   The effectiveness of evaporative cooling is largely dependent on the humidity of the outside air; dryer air produces more cooling. A study of field performance results in Kuwait revealed that power requirements for an evaporative cooler are approximately 75% less than the power requirements for a conventional packaged unit air-conditioner.

6. 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 ...

7. Evaporation - Wikipedia

   Demonstration of evaporative cooling. When the sensor is dipped in ethanol and then taken out to evaporate, the instrument shows progressively lower temperature as the ethanol evaporates. Rain evaporating after falling on hot pavement. Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. [1]
