80 Father of Carrier patents air conditioner entrepreneurial life – air conditio
Summer, most parts of the world's extremely hot, people in air-conditioned home, car and office, no sense of the heat wave, can not help much sigh: who invented air conditioning really great! However, Chang sigh, I am afraid not many people know, 1902 July 17, earns 10 dollars a week, Americans invented the world's first air-conditioners, he is Willis? Havilland? Carrier.
Inspired by the fog
A frosty evening, fog shrouded in Pittsburgh train station. A young man walked up and down the platform, his mind has been plagued by a problem tossing his endless months. With this problem with his sleep, waking up together in the train to work furiously. At the moment, taking advantage of the railway station waiting for the bus Kong Danger, his brain has high-speed operation up … … Suddenly, just as Archimedes year as flashes?? Find out! The answer is on his side, the answer that fog!
The lonely thinker ? Haviland? Carrier (1876 ~ 1950).
Carrier born in November 1876 on a farm in New York, 1901, after graduating from Cornell University, in a warm production scheduling system for companies to do mechanical engineers Buffalo Kaji. Hot and humid summer air that year, Brooklyn's Sackett – Williams production printing and publishing company greatly affected: always quit ink, pigment leakage, paper swollen. The beginning of the second year, the company's director to find Buffalo smithery company, seeking some kind of regulation can be the same as regulating the temperature, air humidity equipment. The company turned over to the Carrier, because the only 25-year-old boy in the heating coil of research, he found his boss from the winter to save heating costs in 4 million.
Centuries, seeking to air cooling method, where the philosopher has been as a satire on people to look at the human long ago learned to cold become hot, but to do things in turn when are lost. Refrigeration area in 1851 achieved two breakthroughs: the French Ferdinand? Carre designed the first ammonia absorption chillers; in the United States, John? Dr. Gregory obtained a patent ice-making device. Since then, the challenge for scientists to control the transfer from the lower temperature and humidity, which is another aspect of the problem.
Carrier initially Sackett – William companies plan to do is: let cold water in the original designed for the heating coil in the loop, thus reducing the surrounding air temperature. Temperature is indeed lower, but the Carrier found that cooling air is still damp after. The "Dew point control" problem has been to his dilemma, until the moment the train station in Pittsburgh, he was to find a solution.
Carrier's creative inspiration is to find such a contradiction: saturated with water "wet" the air is actually dry. He explained: "The fog is so close to 100% humidity of air saturation. Temperature is very low, so even if the air is saturated, in fact it does not contain too much moisture in it. Such a low temperature, air moisture is not may also exist in large quantities. So, if I can let the air is saturated, while controlling the temperature of the air is saturated, I can get a kind of quantitative control the humidity of the air. that I do, and that lets air through a very fine mist sprayer define ghost real. "can be said that spray is hot and humid air to provide a condensation of the interface, moist air to droplets of water condensation, then dropping, what is left is colder more dry air was. The fourth winter, January 2, 1906, Carrier's "air handling apparatus" get a patent.
Into the White House air-conditioning
Although the company promoted Carrier Buffalo Kaji as the leader in engineering, but it is clear that the company is not aware of their grasp is a gold mine. When World War I in 1914, when dark clouds, the air conditioning business enterprises dropped to second place. So Carrier out of there with a friend Owen? Lyle partnership, founded his own company. Carrier responsible for technical, Lyle is responsible for sales.
Carrier Company opened first year, received 40 orders for air-conditioning system, to 1929, already has three factories. 20 years of the 20th century is their glory era. 1924 Carrier of the Hudson department store in Detroit had air conditioning installed in 1928 and 1929 is the White House and the Senate. The result of this new technology the most social sensation occurred in 1925, when the Carrier is working Theatre of central air-conditioning works.
