air conditioning history timeline
Residential air conditioners catch on in suburban homes.
Ancient Egyptians are vaguely credited as being the first to use evaporative cooling by hanging wet cloth or reeds in windows and doorways. As the wind blew across the wet materials, the air in the home would be cooled.
1931: H.H. Schultz and J.Q. Sherman invented the first window unit air conditioner at an extremely steep cost.
Though they had nothing like modern-day air conditioning, human beings used little tricks to cool themselves since ancient times. Though dates aren’t known for some of the early methods of cooling air, there’s evidence of the use of air conditioning science that dates back millennia.
Most Edmonton homeowners are familiar with the air-conditioning manufacturer Carrier, named after the basic founding father of the A/C, Willis Carrier. In 1902 Carrier developed the first electrical air cooling unit that used coils cooled by water to limit the humidity and damage to the paper in the printing plant where he worked. The convenience to people was almost a corollary benefit as the first A/C was developed strictly for industry.
Many of us come home after a hot day in the sun and turn on our air conditioning units like it’s no big thing – nor should it be. Although we’re not sure how the system works, we know that when we hit the ‘on’ switch and turn the temperature down it won’t be long until we’re cooled off.
1931 J.Q. Sherman and H.H. Schultz invented individual room air conditioner, which were installed in windows.
1758 Benjamin Franklin invented that all liquids when evaporated has cooling effects. This was pioneer step towards invention of cooling devices.
Well, this is what they say happened. On a foggy day, Will was walking through a Pittsburgh railway station. The fog sparked the idea in his head of drying the air by producing artificial fog. His original plan was to force air across pipes that were filled with cool water that was drawn from a well located between two buildings. Carrier’s air conditioning system was installed in Brooklyn in 1902, saving the Judge Magazine and perpetuating the birth of the modern air conditioner. Carrier later added a refrigeration machine called, “The Chiller” in order to speed up the cooling process. Carrier was granted his patent on January 2, 1906, and to this day his company, “Carrier Engineering Corporation” is a world leader in both residential and commercial cooling and refrigeration systems.
When movie theaters were introduced, there was a heat problem in the summer. Avid movie goers would complain about the dark, small, enclosed space with the stale smell of sweat. Who would want to sit in the heat of a theater with a bunch of other sweating fans? In 1922, in order to attract more middle- and upper-class viewers, the first well -designed cooling system for theaters was introduced at the Metropolitan Theater in Los Angeles. The system was installed by the Carrier Engineering Corporation. This new mechanism pumped cool air through high vents to control humidity throughout the building. That same year, the Rivoli Theater in New York, introduced a new system that used a centrifugal cooler, which had fewer moving parts. This groundbreaking system was more reliable and more cost effective than its previous counterpart. The new machine lowered the expenses of large-scale air conditioners and expanded air conditioner use throughout the United States.
