The invention of air conditioning can be attributed to several individuals and technological advancements over time. However, the first practical air conditioning system was developed in 1902 by Willis Carrier, an American engineer.
Carrier was working for a printing company in New York, where he observed that temperature and humidity fluctuations were affecting the quality of the paper. He developed a system that could control the temperature and humidity levels in the air, thereby improving the quality of the paper.
Carrier’s system used a refrigeration cycle to remove moisture from the air and maintain a consistent temperature. It consisted of a compressor, condenser, evaporator, and expansion valve, which together could cool the air and control humidity. This invention was later applied to other industries, including movie theaters, department stores, and office buildings.
The invention of air conditioning revolutionized the way people lived and worked in hot and humid climates, and it has become an essential part of modern life.
