who invented the first air conditioning?

Melissa Lavallie: Carrier

Ardath Templer: Best Answer - Chosen By VotersIn 1902, only one year after Willis Haviland Carrier graduated from Cornell University with a Masters in Engineering, the first air (temperature and humidity) conditioning was in operation, making one Brooklyn printing plant owner very happy. Fluctuations in heat and humidity in his plant had caused the dimensions of the printing paper to keep altering slightly, enough to ensure a misalignment of the colored inks. The new air conditioning machine created a stable environment and aligned four-color printing became possible. All thanks to the new employee at the Buffalo Forge Company, who started on a salary of only $10.00 per week....Show more

Madie Strople: The 'Apparatus for Treating Air' (U.S. Pat# 808897) granted in 1906, was the first of several patents awarded to Willis Haviland Carrier. The recognized 'father of air conditioning' is Carrier.

Natalya Sydney: I WON'T ARGUE... BUT! BTU MEANS BRITISH THERMAL UNIT, & TONS CAME FROM HOW MANY TONS OF ICE WERE NEEDED TO DROP THE TEMP 1 DEGREE ( IN A CERTAIN AREA OF SQ FT ) THE BTU WAS ASSIGNED AS A UNIT OF MEASURE. THE LIMEY'S WERE WORKING ON IT TOO, BUT IT TOOK AN AMERICAN TO FIGURE IT OUT!

Cornelius Thornborrow: Willis Carrier did.He owned a print shop and the paper was sticking together in the humid summer.

Ignacio Imbier: "stupid cupid" got that info from here...http://en.wikipedia.org/wiki/Air_conditioner#Histo...

Willa Holte: Some guy with a block of ice and a fan.

Jeannine Vassie: While energetically moving heat to provide air conditioning is a relatively modern invention, the cooling of buildings is not. The ancient Romans were known to circulate aqueduct water through the walls of certain houses to cool them off, thus cooling the interior air. As this sort of water usage was expensive, generally only the wealthy could afford such a luxury.In 1820, British scientist and inv! entor Michael Faraday discovered that compressing and liquefyi! ng ammonia could chill air when the liquefied ammonia was allowed to evaporate.In 1842, Florida physician Dr. John Gorrie used compressor technology to create ice, which he used to cool air for his patients in his hospital in Apalachicola, Florida.[1] He hoped eventually to use his ice-making machine to regulate the temperature of buildings. He even envisioned centralized air conditioning that could cool entire cities.[2] Though his prototype leaked and performed irregularly, Gorrie was granted a patent in 1851 for his ice-making machine. His hopes for its success vanished soon afterwards when his chief financial backer died. Gorrie did not get the money he needed to develop the machine. According to his biographer Vivian M. Sherlock, he blamed the "Ice King," Frederic Tudor, for his failure, suspecting that Tudor has launched a smear campaign against his invention. Dr Gorrie died impoverished in 1855 and the idea of air conditioning faded away for 50 years.Early commercial! applications of air conditioning were manufactured to cool air for industrial processing rather than personal comfort. In 1902 the first modern electrical air conditioning was invented by Willis Haviland Carrier. Designed to improve manufacturing process control in a printing plant, his invention controlled not only temperature but also humidity. The low heat and humidity were to help maintain consistent paper dimensions and ink alignment. Later Carrier's technology was applied to increase productivity in the workplace, and The Carrier Air Conditioning Company of America was formed to meet rising demand. Over time air conditioning came to be used to improve comfort in homes and automobiles. Residential sales expanded dramatically in the 1950s.In 1906, Stuart W. Cramer of Charlotte, North Carolina, USA, was exploring ways to add moisture to the air in his textile mill. Cramer coined the term "air conditioning," using it in a patent claim he filed that year as an analogue to! "water conditioning", then a well-known process for making textiles ea! sier to process. He combined moisture with ventilation to "condition" and change the air in the factories, controlling the humidity so necessary in textile plants. Willis Carrier adopted the term and incorporated it into the name of his company.The first air conditioners and refrigerators employed toxic gases like ammonia and methyl chloride, which could result in fatal accidents when they leaked. Thomas Midgley, Jr. created the first chlorofluorocarbon gas, Freon, in 1928. The refrigerant was much safer for humans but was later found to be harmful to the atmosphere's ozone layer. "Freon" is a trade name of Dupont for any CFC, HCFC, or HFC refrigerant, the name of each including a number indicating molecular composition (R-11, R-12, R-22, R-134). The blend most used in direct-expansion comfort cooling is an HCFC known as R-22. It is to be phased out for use in new equipment by 2010 and completely discontinued by 2020. R-11 and R-12 are no longer manufactured in the US, the ! only source for purchase being the cleaned and purified gas recovered from other air conditioner systems. Several ozone-friendly refrigerants have been developed as alternatives, including R-410A, known by the brand name "Puron".Latest air conditioners usually have air sterilization effects, such as the recent air conditioners that have germicidal and neutralization benefits hope this helps, i just looked it up in the net anyway...Show more
