Why was AC invented?

Humans have searched for ways to stay cool during the hottest days of the year for as long as they have walked the Earth. From Egyptians hanging damp mats over doorways to the Roman aqueducts that circulated cool water, humankind has always had to find creative ways to outsmart the weather.  

However, it wasn’t until the 18th century that the modern history of air conditioning began. Here are some early highlights: 

  • The principles of air conditioning as it is known today are often related to the American statesman and inventor Benjamin Franklin who attributed the refrigeration properties of a liquid to the speed of its evaporation in 1758. 
  • Similarly, Michael Faraday, the British inventor, experimented with the refrigerating effects of certain gases in 1820. He found that he could cool down the air in his laboratory when he compressed and liquidized ammonia and allowed it to evaporate. 
  • In 1851, John Gorrie, a Florida physician used air and compressed water to develop an open cooling system to help cool down yellow fever patients. Gorrie’s “cold air machine” was the first mechanical refrigeration device that resembled air conditioners as we know them today.  

Who Invented Air Conditioning

After years of hard work and creative experiments, the first modern AC system came in the 20th century thanks to Willis Carrier, a young inventor from New York. However, Carrier’s mechanical device wasn’t designed to keep rooms cool, but to maintain appropriate levels of humidity in a printing plant he worked in. Carrier used chilled coils which could both dehumidify and cool down the air inside the plant, keeping the humidity level at a comfortable 55 percent. 

While Carrier’s first air conditioner was installed in 1914, such machines weren’t even close to becoming a common household addition due to their size and noisiness. However, Carrier’s continual experimentation yielded the centrifugal refrigeration machine – an air conditioning unit with a higher efficiency, otherwise known as a “chiller”. Its widespread success made it a popular addition to movie theaters and fancy hotels in the late 1930s.   

From hotels and movie theaters to commercial businesses, cooling systems kept growing in popularity, despite still being considered a luxury for typical American families. The air conditioner’s rise to fame was slow but steady, with the number of American households with AC units jumping from 10% in 1965 to around 86% in 2007. Nowadays, these incredible devices are an inevitable part of the American lifestyle, keeping millions of families cool and fresh during even the hottest of summers. 

Why is it called an air conditioner?

Shortly after Willis Carrier designed his cooling machine, Stuart W. Cramer invented a similar device to add moisture to the stuffy air in his textile plant. Cramer was the first to use the term “air conditioning”, inspired by the idea of “water conditioning”, a then-popular textile making process.

But why is it called an air conditioner, not an air cooler? The answer is quite evident: even though AC units have always been used predominantly to cool down air, their dehumidification properties were precisely why Carrier and Cramer set about inventing them. The AC doesn’t just cool down the air – it conditions it by removing excess moisture, making the atmosphere in your home as comfortable as can be.
