As a Phoenix AC service, Chas Roberts has an appreciation like no other for Willis Carrier, inventor of modern air conditioning. Not only did Carrier make it possible the creation of an artificial climate, he revolutionized American working environments. The Phoenix AC maintenance crew at Chas Roberts applauds him.
Carrier’s model mimicked elementary heating systems that circulated hot water through fans and ducts. Rather than using hot water, Carrier used chilled water and “cooling coils” to make areas colder instead of warmer.
In 1911, Carrier developed the Rational Psychrometric Formulae, which is used to find and analyze the relationship between temperature and humidity and their role in creating a comfortable environment. In 1913, Carrier took his original invention a step further and created the Carrier Air Humidifier. Three years later, Carrier’s air conditioner was installed at the Barber Creamery in Chicago, making it the first air-conditioned dairy products. Though revolutionary in the working world, Carrier’s invention did not become a household item until 1926.
Willis Carrier died October 7, 1950 in New York City. In 1985 Carrier was inducted into the National Inventors Hall of Fame, and in 1988 he was named one of TIME magazine’s “100 Most Influential People of the 20th Century.”
