Air conditioning
In 1902, the first modern electrical air conditioning unit was invented by Willis Carrier in Buffalo, New York. After graduating from Cornell University, Carrier found a job at the Buffalo Forge Company. There, he began experimenting with air conditioning as a way to solve an application problem for the Sackett-Wilhelms Lithographing and Publishing Company in Brooklyn, New York. The first air conditioner, designed and built in Buffalo by Carrier, began working on 17 July 1902.
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.
