The American inventor Willis Havilland Carrill (some locals translated as Carrier), known as the father of refrigeration, designed and installed the first Willis Havilland Card in 1902. Lille air conditioning system. A printer in New York, USA, found that changes in temperature could cause paper distortion, which led to a misalignment of colored ink. The air conditioning system was designed for him. Carrill's patent was registered in 1906. On July 17, 1902, Carrill, a young man who graduated from Cornell University for a year, invented the air conditioner when he worked at Buffalo Forge Co. However, the purpose of inventing the air-conditioner was not to provide a comfortable living environment for people, but to serve some dead things. It is said that one of the Buffalo's customers, the Shakter William Printing Factory in New York, whose printing machine changed the temperature and humidity of the air, causing the paper to expand and contract, and the ink is not aligned, and it is impossible to produce clear color prints. . So I turned to the buffalo company. Carrill thought that since the air can be kept warm by the steam-filled coil, why not use the air to cool down through the coil filled with cold water? The water in the air will condense on the coil, so that the air in the factory will be cool. Dry again. Central air conditioning host On July 17, 1902, the era of air conditioning began with the first use of air conditioners by the printing plant. Soon, other industries such as textiles, chemical industry, pharmaceutical industry, food and even arms, etc., have also greatly improved the quality of their products due to the introduction of air conditioners. In 1907, the first air conditioner to be exported, the buyer was a silk factory in Japan. In 1915, Carrill established a company and it is still one of the world's largest air-conditioning companies. But after 20 years of air-conditioning invention, the enjoyment has always been machines, not people. Until 1924, a shopping mall in Detroit, often because of the sweltering weather, many people fainted, and first installed three central air conditioners, this was a great success, the cool environment made people's spending desires increase, since then, air conditioning It has become a powerful tool for businesses to attract customers, and the era when air conditioners serve people has officially arrived. But when it comes to air conditioning, it is popular, mainly through cinemas. Most Americans are exposed to air conditioning for the first time in a movie theater. The cinemas of the 1920s used air-conditioning technology to promise to provide cool air to the audience, making the air-conditioner as attractive as the movie itself, and the summer season replaced the winter season of watching movies. A large number of indoor entertainment venues, such as casinos, indoor sports courts and shopping malls, which were open all year round, were attributed to the emergence of air conditioners. In the 1960s and 1970s, rare dry weather occurred in the United States. In order to solve the problem of air conditioning cold and heat sources in drought-deficient areas, the United States took the lead in developing air-cooled chillers and replacing the cooling towers with air cooling. The name is: Air cool Chiller, referred to as Chiller! In the history of air conditioning, the United States has developed and improved a central unit system with ducts, and has received strong support from air conditioner distributors and distributors who are installing and repairing unit air conditioning systems with ducts on site. WRAC is the simplest and cheapest system that can be easily purchased in retail stores and installed itself at high temperatures. At the same time, the ductless SRAC and SPAC have been developed and improved in Japan since the 1970s under the power of the US market. Later, equipment design and manufacturing technology was transferred to China in the 1990s, a joint venture with local companies including local components such as compressors, heat exchangers, motors, fine valves and electronic controllers. ongoing. In the 1990s, China also absorbed advanced high-tech from large air-conditioning equipment from other advanced countries, and formed a joint venture with most large companies in the United States. Today China is already a top country, and her major local factories and joint ventures manufacture a large number of SRAC and SPAC to meet the growing domestic market and export needs. In the past few years, Japan has exported SRAC and SPAC units to China, Europe and the Middle East to establish new markets. However, China is now the largest exporter of air conditioners. In 2001, the total number of WRAC, SRAC and SPAC units exported reached 5 million units. In 2002, 750 or 8 million units were expected to be exported, and Japan is losing its export status. From January to October 2008, China's air-conditioning industrial enterprises realized a total industrial output value of 143,283,146 thousand yuan; realized cumulative product sales income of 151,410,493,000 yuan; realized cumulative total profit of 5,165,862,000 yuan.
