Willis Carrier is the inventor of modern air conditioning. Carrier’s company, Carrier Corporation, was one of the first to sell central cooling systems in the United States. In 1913, he patented a design for an electric refrigeration system that produced cold air by compressing ammonia. He also designed and manufactured the world’s first complete air conditioning system for a department store in 1922.

Willis Haviland Carrier was born in 1876. He was a pioneer of the American industrial revolution, who helped develop major advances in air conditioning and refrigeration. Carrier had an interest in engineering from a young age; he loved to tinker with things that he found on his family farm and try to make them work better. His life as an engineer began when he attended Cornell University’s Sibley College of Engineering at the age of 16, where he studied mechanical engineering. It was here that Carrier learned about new advancements in air conditioning technology that had been created by engineers before him, such as Frederick Mears, who invented the Mears Method for cooling buildings by using a compressor-driven gas or vapor to remove heat from inside the building without moving air outside it. This technology could only be used seasonally though; because more than half of all US energy consumption at this time came from coal power plants which were not able to produce enough electricity during winter months when demand was high but production decreased due to colder weather conditions. Carrier did not want people living through the harsh winters without any form of relief so he developed what is now known as “The Carrier Air Conditioning System”. This system allowed for cool air to be distributed evenly

Carrier was the founder of what became known as Air Conditioning and Refrigeration Institute (ARI). Thermal electric refrigeration is a process that involves cooling an enclosed space through the use of a heat pump or absorption chiller. The heat pump or absorption chiller extracts heat from the enclosed space and transfers it to ambient air outside. This reduces the temperature inside to below the wet-bulb temperature at which evaporative cooling becomes possible with air moving across a liquid-saturated surface such as soil or cloth.
