In buildings they are only required when the building itself is not constructed so that it is able to dissipate enough heat. Methods to construct buildings in such a fashion that additional air coolers are not required are eg Earth sheltering or specific building designs.<ref>[http://www.inhabitat.com/2007/12/10/building-modelled-on-termites-eastgate-centre-in-zimbabwe/eastgate-centre-biomimetic-architecture-biomimicry-biomimetic-design-biomimicry-of-termite-mounds-green-building-with-termites-eco-building-sustainable-design-harare-zimbabwe-africa-sustain-4/ Eatgate Center heat dissipating building design]</ref>\n\n=== Types of Air Coolers ===\n\n# '''Wet Air Coolers''': Use evaporative cooling to reduce air temperature.\n# '''Dry Air Coolers''': Rely on air-to-air heat exchange without the use of water.\n# '''Absorption Air Coolers''': Utilize heat energy to provide cooling.\n# '''Deep Water Source Cooling Systems''': Use cold water from deep water bodies.\n# '''Ground-Coupled Heat Exchangers''': Use the earth's natural temperature for cooling.\n# '''Air and Water-Coupled Heat Pumps''': Transfer heat from air or water to cool spaces.\n\n=== Benefits ===\n\n* '''Energy Efficiency''': Many air coolers are more energy-efficient compared to traditional air conditioning systems.\n* '''Environmentally Friendly''': Air coolers, especially evaporative coolers, use less electricity and do not rely on harmful refrigerants.\n\n=== Applications ===\n\n* '''Residential''': Used in homes for personal comfort.\n* '''Commercial''': Employed in offices, warehouses, and other commercial buildings.\n* '''Industrial''': Utilized in factories and large industrial settings for climate control.\n\n=== Devices ===\n\nSeveral devices exist, these include:\n\n* [[Evaporative cooler|Wet air cooler]]s\n* Dry air coolers\n* Absorption air coolers\n* Deep water source cooling system\n* Ground-coupled heat exchanger\n* Air and water-coupled [[heat pump]]s\n\nCoolers outfitted with extras as heating and dehumidifying are called [[Air conditioning|Air conditioners]].\n\nAir coolers provide an effective and energy-efficient way to cool indoor spaces, offering an alternative to traditional air conditioning systems. They are versatile, with various types available to suit different needs and environments.\n\n==== References and External Links ====\n\n# [https://zwia.org Zero Waste International Alliance]\n* [[Air conditioning]]\n* Air heater\n* [[How to cool a room with water]]\n\n<references />\n\n=== External links ===\n\n* [[Wikipedia:Air cooler]]\n\n{{Page data\n| license = CC-BY-SA-3.0\n| keywords = Cooling technology, Heating, ventilating, air conditioning\n| sdg = SDG07 Affordable and clean energy\n| description = Air coolers save energy and reduce emissions.
