Air conditioning
Modern air conditioning emerged from advances in chemistry during the 19th century, and the first large-scale electrical air conditioning was invented and used in 1902 by US inventor Willis Carrier. The introduction of residential air conditioning in the 1920s helped enable the great migration to the Sun Belt in the United States.
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.
