Timeline of United States inventions (1890–1945)
Air conditioning is the cooling and de-humidification of indoor air for thermal comfort. Using a system of coils as a solution to cool and remove moisture from muggy air in a printing plant that was wrinkling magazine pages, Willis Carrier invented and manufactured the world's first mechanical air conditioning unit in 1902. Carrier's invention – encompassing the first system to provide man-made control over temperature, humidity, ventilation and air quality, was first installed as a solution to the quality problems experienced at a Brooklyn printing plant, Sackett-Wilhelms Lithographing and Publishing Company. Air conditioning not only spawned a company and an industry, but also brought about profound economic, social and cultural changes.
History of Chrysler
Airtemp invented capacity regulators, sealed radial compressors, and the self-contained air conditioning system, along with a superior high-speed radial compressor, and by 1941 had over 500 dealers selling its air conditioning and heating systems. The company supplied medical refrigeration units in World War II, and dominated the industry in the 1940s but slowly fell behind. By the 1970s Airtemp was losing money and was sold to Fedders in 1976. In 2012 the name was reborn as a Nordyne byproduct exclusively sold by the R.E. Michel Company.
