The history of air conditioning is much older than Willis Carrier’s 1902 invention. Learn more about who invented air conditioning today.
In the beginning, it wasn’t the heat, but the humidity. In 1902, the workers at Sackett & Wilhelms Lithographing & Printing Company in New York City were fed up with the muggy summer air, which kept morphing their paper and ruining their prints. To fix the problem, they needed a humidity-control system. The challenge fell to a young engineer named Willis Carrier. He devised a system to circulate air over coils that were cooled by compressed ammonia. The machine worked beautifully, alleviating ...
For many of us, air conditioning is essential to cool off in summer heat. But where did air conditioning come from, and where is it headed?
Date Published: Jun 6, 2011, Author: John Varrasi ; This story was updated on 10/7/2022. With summer’s soaring temperatures and unbearable humidity, millions of people turn to a marvel of discovery and invention: the air conditioner. These comfort units that homeowners activate with the ease of flipping a switch are complex electromechanical systems—the end products of nearly a century of engineering development in cooling, thermodynamics, controls, and energy efficiency. In fact, in 2000, a...
