Thanks Mr. Carrier!

The History of Air Conditioning By Lou Kren
Alfred Wolff, Stuart Cramer and Willis Carrier are the three men most responsible for the introduction of air conditioning and climate control, according to Gail Cooper, author of Air Conditioning America: Engineers and the Controlled Environment, 1900-1960. The three carried on where a some left off, namely John Gorrie, a Florida physician who, in 1842 envisioned mechanically cooled houses and even centralized refrigeration plants for whole cities. Later, he also saw cooling as beneficial for manufacturing plants, which, with cooled interiors, could operate in warmer climates and operate continuously in temperate regions. [...] Despite the efforts of innovators such as Wolff and Cramer, air conditioning, at the beginning of the 20th century, was reserved only for the very rich, and systems were custom-designed, adding cost, inviting trial-and-error installation and necessitating constant repair and adjustment. Willis Carrier, heralded as "the father of air conditioning," would make air conditioning an inviting option and would standardize equipment, paving the way for the climate systems we enjoy today. In 1902, fresh out of Cornell University and working as an engineer at Buffalo Forge Co., Carrier developed the world's first modern air conditioner, combining temperature and humidity control in one system, for a Brooklyn, NY, printing plant. He earned a patent for this system design in 1906. His air conditioner used a centrifugal system, under low pressure, to gather air through a filter and pass that air over coolant-filled coils. That cooled and dehumidified air was directed at its target location while warmer air around the motor was vented out of the location. The technology behind Carrier's air conditioner was patented in 1911 and is the basis for air conditioner technology available today.
A big thank you to the innovators in air conditioning! Willis Carrier Inspired by Annika.
