Q: How long has air conditioning been around?
A: Mechanical artificial cooling dates back to the 1840s, when physician and inventor Dr. John Gorrie of Florida proposed cooling cities to relieve residents of “the evils of high temperatures.”
“To get around this expensive logistical challenge, Gorrie began experimenting with the concept of artificial cooling,” the article says. He designed a machine that created ice using a compressor powered by a horse, water, wind-driven sails or steam and was granted a patent for it in 1851. “While working for the Buffalo Forge Company in 1902, Carrier was tasked with solving a humidity problem that was causing magazine pages to wrinkle at Sackett-Wilhelms Lithographing and Publishing Company in Brooklyn,” the article says. “Through a series of experiments, Carrier designed a system that controlled humidity using cooling coils and secured a patent for his ‘Apparatus for Treating Air,’ which could either humidify or dehumidify air.
