Apparatus For Treating Air

Air conditioner has become an Integral part of our daily life. But, do you know who invented it? The technology and formulas that made air conditioning possible were developed by American engineer and inventor Willis Haviland Carrier.

Carrier, who was up in Western New York not far from Angola, attended Cornell University and received his M.E. in 1901. In just one year, his first scientific air conditioning system had its first operational installation, controlling humidity and temperature in a Brooklyn printing company. His Patent number on Air Conditioner is US Patent No. 808897.


"Apparatus for Treating Air," which he rightly predicted would be used to improve industrial processes and goods, was the world's first spray-type air conditioning device. The American Society of Mechanical Engineers received the "Rational Psychometric Formulae" that Carrier had developed in 1911.

The equations continue to serve as the foundation for all essential computations in the air conditioning sector. The era of comfort chilling began when he created the first safe, lowpressure centrifugal refrigeration device employing nontoxic, nonflammable refrigerant.

Carrier earned multiple patents for the new safe refrigerants that resulted from his early work building centrifugal refrigeration equipment. He created modern air conditioning by regulating humidity in addition to temperature. With $35,000 in funding, Carrier and three other engineers founded the Carrier Engineering Corporation in 1915.
