The History of oo ittockotolge AIR CONDITIONING dooodoooroooo Long before air conditioning came along people tried interesting tactics to outsmart the weather. Bob Jenson Air Conditioning and Heating Inc. explores the history of air conditioning as one of man's greatest inventions. 1830s Dr. John Gorrie, a physician from Florida, attempted to build the first air conditioner that essentially blew air over a bucket of ice for cooling hospital rooms of patients suffering from malaria and yellow fever. omogooo.ot Geto 8 88| ....... After President James A. Garfield was shot by his assassin, naval engineers rigged an air conditioner to keep the dying president cool. A fan blew air over a box containing cloths soaked in icy water, cooling his room by twenty degrees. tamstik American engineer Willis Carrier invents an "apparatus for treating air" for a publishing company in Brooklyn, New York. Chilled coils were used in Carrier the machine to cool air and lower humidity to 55 percent. olotoopcrk 1914 The first air-conditioned home was AMNIA that of Charles Gates in Minneapolis. The flaw of these revolutionary units, however, was that they were bulky, expensive, and dangerous due to toxic ammonia that served as a coolant. 02| Willis Carrier patents the centrifugal refrigeration machine, which was the first practical method of air conditioning large spaces. This revolutionized industries looking to control temperatures and humidity levels for food storage. 1922 oTolololo dlon loofoto Willis Carrier replaces the ammonia Cantriénnal coolant with the benign deilene coolant and also adds a central compressor to reduce the size of the unit. oood.00 WWII Window units appear with sales escalating from 74,000 units in 1948 over a million in 1953. Today olottoototo Air conditioners are more efficient and eco-friendly than ever. Air conditioners are a revolutionary invention for climate control, and certainly one that is hard to imagine living without. Gotoigdo ..... ..... SOURCES: Jones Jr., Malcolm. "Air Conditioning".
