TRANSCRIPT
History of Adiabatic /
Evaporative Cooling
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.
1902: Willis Haviland Carrier invents and patents
the first modern electrical air-conditioning for
industrial plants in the United States.
