The Origin Of Air Conditioner

Around 1700 BC, the Babylonians had invented an ancient air-conditioning system that used wind poles installed on the roof to use natural wind from the outside to pass through the cold water and blow into the room, making the people inside feel cool.

In the 19th century, British scientist and inventor Michael Faraday (Michael Faraday) discovered that compressing and liquefying a certain gas can freeze air. This phenomenon occurs when the liquefied ammonia vapor evaporates. At that time, the idea was still theoretical.

In 1842, Florida doctor John Gorrie built a new building with central air conditioning. An engineer from Hoboken, New Jersey, Alfred Wolff, assisted in the design of this new air conditioning system and moved the technology from the textile factory to the commercial building. He is considered one of the pioneers in making the working environment cooler.

In late 1902, the first modern, electric-powered air conditioning system was invented by Willis Carrier (1876-1950). The difference between its design and Wolff's design is not only to control the temperature, but also to control the humidity of the air to improve the quality of the production process at a printing factory in Bucklin, New York. This technology provides a low heat and humidity environment to make the paper area and ink arrangement more accurate. Later, Carrier's technology began to be used in the workplace to improve production efficiency. Carrier Engineering Company was also established in 1915 to cope with the surge in demand. Under the gradual development, air conditioning began to be used to improve the comfort in homes and cars. Sales of residential air-conditioning systems did not really take off until the 1950s. Built in 1906, the Royal Victoria Hospital in Belfast, Northern Ireland, is of special significance in architectural engineering and is known as the world's first air-conditioned building.

In 1906, Stuart W. Cramer of Charlotte, North Carolina, USA was looking for ways to increase the air humidity in his southern textile mill. Cramer named the technology air conditioning and used it in a patent application in the same year as a substitute for water conditioning. Water conditioning was a well-known procedure at the time, which made the production of textiles easier. He combined water vapor and ventilation systems to "regulate" and transform the air in the factory, and control the air humidity, which is very important in the textile factory. Willis Carrier used this name and put it in the name of the company he founded in 1907: "Galia Air Conditioning Company" (now Carrier Company).

In 1915, Carrier established a company, which is one of the largest air-conditioning companies in the world. But 20 years after the invention of the air conditioner, machines have always been enjoyed, not people. Until 1924, a mall in Detroit often fainted due to the sweltering weather, and first installed three central air conditioners. This was a great success. The cool environment made people's desire for consumption greatly increased. Since then, air conditioning As a powerful tool for businesses to attract customers, the era of air conditioners serving people has officially arrived.
