(Our Tech Blog) Beginning of the AC (air conditioner) has been started since Roman times is to create a reservoir of water flowing in the walls of the house thus lowering the temperature of the room, but then only certain people who can build it because the cost is very expensive because it requires water and also buildings that do not usual. Only the kings and rich people who can build it.
Quoted from kaskus, only later in 1820 the British scientist named 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 hospital who was in Florida Apalachicola United States. Dr.Jhon Gorrie is found and this was the forerunner of the technological AC (air conditioner) but unfortunately he died before complete in 1855.
Willis Haviland Carrier an engineer from New York United refine the discovery of Dr.Jhon Gorrie but AC is used instead for the benefit or convenience of humans but for the purposes of printing and other industries.
The use of air conditioning for new housing was developed in 1927 and first used disbuah house in Mineapolis, Minnesota. Currently AC is used in all sectors, not only industry but also has been in office and residential with a variety of forms ranging from large to the kecil.semuanya still serves the same which is to cool the temperature of the room so that people feel comfortable.
When summer comes, we usually always familiar with that name is also a fan or AC (Air Conditioner).
Therefore, the coolness caused by the air fan and air conditioning is needed to reduce the heat that is sometimes excruciating.
Because of that, thank John Gorrie who sparked the idea of making air-conditioning. Because, with the cool air conditioning, we need not feel pain because of the heat which sometimes makes the body feel like a sticky due to sweat dripping. But, do you know if John created the AC because it was inspired by concern for the sick?.
Once, John is actually a doctor United States citizens. The idea makes cooling engine starts from the number of patients suffering from malaria or other disease of the symptoms of high fever. When the air was hot, so make the patient uncomfortable. So, who was born in Charleston, South California, October 3, 1802 is rack my brain how to keep the patient's body temperature can go down. After seeing the fan in front of him, he found the idea. He put a chunk of ice in front of the fan, so cold the ice can be spread by wind from the fan.
Sparked the idea, then John intends menyeriusi manufacture of engine cooling (AC). Then, in 1844, he graduated from medical and surgical science in the city of New York is designing and developing ice-making machine experiments. Creation engine is based on the laws of physics that heat always flows from a gas or liquid that is hotter toward the gas or fluid cooler. The machine works by compressing the gas (compress) so it gets hot, then gases are channeled to the coils for reduced pressures (decompress). As a result, the air became cold.
To develop the discovery, in 1845, Gorrie decided to stop the practice as a doctor. Six years later, he successfully received a patent which is the first patent issued for an engine coolant. This was originally found that the engine coolant is now known as the Air Conditioner.
