Willis Carrier submitted drawings of the first modern air conditioning system on July 17, 1902.
Carrier was working to solve a problem that effected the quality of printing…
He came up with the brilliant idea to circulate cold water rather than steam through heating coils in a machine he used to test heaters.
Carrier’s design was credited as the first to address four basic functions necessary for air conditioning. An air conditioner must: 1. control temperature, 2. control humidity, 3. control air circulation, and 4. cleanse the air.
After the first appearance of Carrier’s air conditioner drawings in 1902, the air conditioner has revolutionized the comfort of people in many different activities.
This timeline from Carrier highlights some of the major impacts of air conditioning on society.
