Chapter 2: His Invention

On July 17, 1902, when he was living in Buffalo, New York, he designed what is known as the first modern air-conditioning  system. It was for a company called Sackett-Wilhelms Lithographing & Publishing Company of Brooklyn.


Carrier felt that for  people to be comfortable, temperature  and humidity should be controlled. People loved his air-conditioner! They thought it was comfortable and refreshing!


Today we still use the equations he came up with when we build new air-conditioners.

At first air conditioners were just used in factories where it was important to control temperature. Soon it became popular for theatres  to have them for the comfort of their audience. They wanted more people to come to the theatre in the hot summer weather.


Today many buildings, cars and homes use air-conditioning



Even though Willis Haviland Carrier died in 1950, he will always be remembered for being the inventor of modern air-conditioning.
