HISTORY OF AIR COOLERS
Ancient Egypt: Ancient Egyptian fresco paintings illustrating slaves fanning large, porous clay jars filled with water show the first records of utilizing evaporative cooling.
Roman Empire: Wealthy Romans circulated water from the aqueducts through the walls of their houses to maintain a cooler air temperature. Many of the common people survived the heat by hanging wet mats over the doors of their tents or dwellings.
Medieval Persia: The first man-made evaporative cooling structures, towers that trapped wind and funneled it past water at the base and into a building, are thought to have developed in Persia.
Renaissance: Leonardo DaVinci, one of the greatest revolutionary minds, helped further improve the concept of evaporative cooling systems through his sketches of water and energy.
1800s: New England textile manufacturers began using water evaporative systems to cool the air in the mills.
1902: Willis Haviland Carrier invents and patents the first modern electrical air-conditioning for industrial plants in the United States.
1916: First “swamp cooler” (i.e. evaporative cooling system) was implemented in the Adams Hotel in Downtown Phoenix, Arizona.
1920s – 1930s: Settlers traveling in the West reported sleeping on screened-in porches and hanging wet sheets on the mesh to try to remain cool throughout the night.
2000s: Environmental awareness increase and many HVAC companies attempt to restructure products to run more efficiently. Products do not offer a comprehensive solution to environmental and cooling needs.
