Who invented air conditioning?

Willis Haviland carril, an American inventor known as the father of refrigeration, designed and installed the first air conditioning system in 1902. The air conditioning system was designed for a printer in new york, USA. The printer found that the change of temperature would lead to the deformation of paper, which would lead to the imbalance of color ink. Carrier's patent 1906 was registered. On July 1902, a young man who just graduated from Cornell University for one year invented air conditioning while working in Buffalo Fauci Company, but the original purpose of air conditioning was not to bring people a comfortable living environment, but to serve some dead things. It is said that one of Buffalo's customers, William Printing House in Chakot, new york, has a printing machine. Due to the change of air temperature and humidity, the paper expands and contracts, and the ink is misaligned, so it is impossible to produce clear color printed matter. So I turned to Buffalo Company. Carrier thinks that since air can be kept warm by coils filled with steam, why not cool the air by coils filled with cold water? The water in the air will condense on the coil, so that the air in the factory will be cool and dry. Central air conditioning host

1902, 17 In July, with the first use of air conditioning in this printing house, the air conditioning era began. Soon, other industries, such as textile, chemical, pharmaceutical, food and even arms industry, also greatly improved the product quality because of the introduction of air conditioning. 1907, the first buyer to export air conditioners was a Japanese silk factory. 19 15, carrier established a company, which is still one of the largest air conditioning companies in the world. But in the 20 years after the invention of air conditioning, it has always been machines rather than people. Until 1924, in a shopping center in Detroit, many people often fainted because of the sultry weather. Three central air conditioners were installed for the first time and achieved great success. The cool environment has greatly increased people's desire for consumption. Since then, air conditioning has become a powerful tool for businesses to attract customers, and the era of air conditioning serving people has officially arrived.
