In antiquity, Egyptians were using systems and methods for reducing heat. It was used mainly in Pharaoh's palace, whose walls were made of huge blocks of stone, weighing more than a thousand tons weight.
Overnight Three thousand slaves dismantled the walls and carted the stones Sahara Desert. As the desert extreme climate and temperature decreases to very low levels during the night, the stones cooled considerably.
Just before dawn, the slaves hauled the stones back to the palace and returned to put in place. It is assumed that the pharaoh was enjoying temperatures around 26 ° Celsius, while outside the heat went up almost double.
If then, thousands of slaves were needed to perform the work of an air conditioning, now this is easily done.
In 1842, Lord Kelvin invented the first air conditioner. In order to achieve a pleasant and healthy environment, the scientist created a hermetic refrigeration system based on the absorption of heat through a cooling gas. This was based on 3 principles:
· Heat is transferred from the higher temperature to the lowest, as when entering a cafe chilled metal spoon into the bowl and it absorbs heat
· The state change of the liquid to gas it absorbs heat. For example, if alcohol moistens hand, we feel cold when it evaporates as it absorbs heat from your hand.
· The pressure and temperature are directly related. In a closed container such as a pot, we need to provide less heat to reach the same temperature as one open
An air conditioner is used, as the name implies, for the air conditioning. This is the most complete treatment process environment indoors and is to regulate the temperature, either heating or cooling, humidity, renewal or ventilation and cleanliness, i.e. its filtering or purification.
In 1902, Willis Carrier US laid the groundwork for modern refrigeration and to meet the problems of over-humidification of air cooled, the air conditioning, HVAC developing the concept of summer.
By that time, a printer from Brooklyn, New York, had serious difficulties during the printing process, because changes in temperature and humidity in your shop slightly altered the dimensions of the paper, preventing correctly align the inks. Frustrated printer could not print a decent color image.
Carrier, a recent graduate of Cornell University with a Masters in Engineering, had just been employed by the Buffalo Forge Company, with a salary of $ 10 per week. The young man began to investigate how tenaciously the problem and designed a machine that controlled the temperature and humidity through cooled tubes, leading to the first air conditioning unit in history.
The invention of printing was happy to Brooklyn, he was finally able to have a stable environment that allowed you to print four color without any complications. The "Apparatus for Treating Air" was patented in 1906.
Although Willis Carrier is recognized as the "father of air conditioning," the term "air conditioning" was first used by engineer Stuart H. Cramer, the patent for a device that sent steam into the air in plants textiles to condition thread.
The textile industries of the Southern United States were the first to use the new Carrier system. For example, the factory Chronicle Cotton Mill in Belmont, North Carolina, I had a big problem. Due to the absence of moisture, excessive static electricity are created, causing the cotton fibers fray and was difficult to weave. Carrier system rose and stabilized humidity for conditioning the fibers, thereby resolving the issue.
Because of its quality, many industries were interested in the Carrier unit. The first sale was made abroad in 1907, to a silk factory in Yokohama, Japan.
