Who invented air conditioning?

Development course of air conditioning

Willis Haviland Carrier, 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. He found that the change of temperature would cause the deformation of paper, which would lead to the imbalance of color ink. Carrier registered the patent 1906.

July 1902 Carrier, a young man who just graduated from Cornell University for one year, invented air conditioning while working in Fudge Company in Buffalo, 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 Factory in Xiakete, new york, has a printing machine that causes the paper to expand and contract due to the change of air temperature and humidity, and the ink is misplaced, so that clear color printed matter cannot be printed. So I turned to Buffalo Company. Carrier thinks that since air can be kept warm by coils filled with steam, why not use air to cool down by coils filled with cold water? The moisture in the air will condense on the coil, so that the air in the factory will be cool and dry.

1902, 17 July, the air-conditioning era began with the first use of air-conditioning in this printing house. 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 its company, and it 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 a machine, not a person. Until 1924, in a shopping mall in Detroit, many people often fainted because of the sultry weather. Three central air conditioners were first installed, which was a great success. The cool environment has greatly increased people's desire for consumption. Since then, air conditioning has become a powerful tool for merchants to attract customers, and the era of air conditioning serving people has officially arrived.

But when it comes to air conditioning, it can be popularized, mainly through cinemas. Most Americans first came into contact with air conditioning in the cinema. In the 1920s, cinemas used air-conditioning technology, promising to provide cool air for the audience, making air-conditioning as attractive as the film itself, and summer replaced winter as the peak season for watching movies. Subsequently, a large number of indoor entertainment places such as casinos, indoor gymnasiums and shopping malls opened all year round, all thanks to the appearance of air conditioning.

In the 1960s and 1970s, there was a rare dry weather in the United States. In order to solve the problem of cold and heat sources of air conditioning in arid and water-deficient areas, the United States took the lead in developing air-cooled chillers, replacing cooling towers with air heat dissipation. Its English name is: Air cool Chiller, or Chiller for short!

In the history of air-conditioning, the United States has developed and improved the central unit air-conditioning system with air ducts, and has received strong support from air-conditioning equipment dealers and distributors who are installing and maintaining the unit air-conditioning system with air ducts on site. WRAC is the simplest and cheapest system, which can be easily purchased in retail stores and installed by itself when the continuous high temperature comes. At the same time, SRAC without air ducts and special purpose acquisition companies have been developed and perfected in Japan since 1970s, driven by different American markets. After that, the technology of equipment design and manufacturing was transferred to China in 1990s, and it was carried out through joint ventures with local companies (including local manufacturers of major components such as compressors, heat exchangers, motors, fine valves and electronic controllers). In the 1990s, China also absorbed the advanced technology of large air-conditioning equipment from other advanced countries and established joint ventures with most large American companies. Today, China is a top country, and its major local factories and joint ventures produce a large number of SRAC and special purpose acquisition companies to meet the growing domestic market and export demand. In the past few years, Japan has been exporting SRAC and special purpose acquisition company products to China, Europe and the Middle East to open up new markets. However, China is now the largest exporter of air conditioners. In 200 1 year, the total export volume of WRAC, SRAC and special purpose acquisition companies reached 5 million units, and it is estimated that 7.5 million or 8 million units will be exported in 2002, while Japan is losing its export status.

From June 5438+0 to June 5438+0, 2008, the total industrial output value of air-conditioning enterprises in China was143,283,146,000 yuan; Realize the cumulative product sales income of 15 1 410493,000 yuan; The total accumulated profit is 5165.862 million yuan.
