The cooling technique has been started since Roman times, namely by making water reservoirs that flow inside the walls of the house so that it lowers the room temperature, but at that time only certain people could because the cost of building it was very expensive because it required water and also an unusual building. Only kings and rich people can build it.
Only then in 1820 British scientist Michael Faraday discovered a new way to cool the air by using Ammonia Gas and in 1842 a doctor found a way to cool the room in the Apalachicola hospital in Florida, United States.
Dr. John Gorrie was the one who discovered it and this is the forerunner of AC technology (air conditioner) but unfortunately before it was perfect he died in 1855.
Willis Haviland Carrier, an engineer from New York America who is also known as the inventor of modern air conditioners, has perfected the invention of Dr.John Gorrie but this air conditioner is used not for the benefit or convenience of humans but for printing and other industrial purposes.
The use of air conditioning for housing was only developed in 1927 and was first used in a house in Minneapolis, Minnesota.
John Gorrie's invention of the ice machine John Gorrie
John Gorrie was born October 3, 1803 - and died June 29, 1855. He was a physician, scientist, inventor, and humanitarian.
Born on the Island of Nevis to Scottish parents on October 3, 1803, he spent his childhood in South Carolina. He received his medical education at the College of Physicians and Surgeons of the Western District of New York in Fairfield, New York. In 1833, he moved to Apalachicola, Florida, a port city on the Gulf coast.
Apart from being a resident doctor at two hospitals, Gorrie is active in the community. On various occasions he served as a board member, Postmaster, President of the Bank of Pensacola at the Apalachicola Branch, Secretary of the Masonic Lodge, and was one of the founding vestrymen of Trinity Episcopal Church.
Dr. Gorrie's medical research involved the study of tropical diseases. A theory that bad air causes disease is a common hypothesis and based on this theory, he urged the draining of swamps and cooling of sickroom's.
For this he cooled the room with ice in a basin hanging from the ceiling. Cold air, becoming heavier, flows down across the patient and through an opening near the floor. Since the ice had to be brought in by boat from the northern lakes, Gorrie experimented with making artificial ice.
After 1845, he gave up his medical practice to pursue the refrigeration project. On May 6, 1851, Gorrie was granted Patent No. 8080 for an ice-making machine. The original model of this machine and the scientific articles he wrote are at the Smithsonian Institution.
Gorrie attempted to raise money to manufacture his engine, but the attempt failed when his partner died. Gorrie died in exile on June 29, 1855. He is buried in Gorrie Square Apalachicola.
Thanks to Gorrie's services, currently AC has been used in all sectors, not only in industry but also in offices and housing in various forms, from large to small. Everything still functions the same, namely to cool the room temperature so that people feel comfortable.
