Picture cooling towers Persian The ancient Romans also install plumbing wall surrounds to circulate

Air conditioner (air conditioner) is a household electrical products popular all over the world. Especially in a tropical country like Vietnam, was living and working in a cool environment created by the air conditioning needs of everyone. In the hot summer days like today, the air is an indispensable product for each of us. Forum "Each week one invented" this time with you will find the history of the air, from the earliest models commercial soup warmer to the modern refrigerator that you are using today. Once again encounter the ancient Egyptians ... Summary of significant milestones in the development of modern air conditioning
The drawing on the wall cooling method described by moisture of the ancient Egyptian archaeologists and historians believe that the model of air conditioning has been the most primitive ancient Egyptians applied reeds by hanging on the windows and spraying it on. When the wind blows through the window carrying steam and cooling the air inside the room. In addition, this method also helps moisten the ancient Egyptians in the atmosphere, avoiding the hot dry desert climate.
Picture cooling towers Persian The ancient Romans also install plumbing wall surrounds to circulate cooling water house. Another technique is also used by the medieval Persian to cool the air. It is a system that includes water tanks and wind towers to cool the indoor air into the heat time.
The activity diagram of wind tower cooling system 2nd century Han Dynasty in China, the inventors have created an adjournment "fans" to cool the air. This system consists of 3 wheels with a diameter of 3 meters and is rotated by hand to create airflow. In 747, Emperor Xuanzong (712-762) was inserted using a cooling tower in the palace called honesty. The ancient text describes the system including the water wheel to generate power with winds bring cooling air moisture. Until Tong in China, the ancient document also refers to the use of air cooling system above widely by many different subjects. All these developments are starting the physical principles - 17th century chemist at, Drebble inventor Cornelis commercial soup warmer (1572-1633) introduced the computer model made by adding salt air into water. He named this system is "turning commercial soup warmer Summer into Winter" and presented to the king of England at that time was James I.
Inventor John Hadley (1731-1764), who discovered the relationship between the evaporation of the liquid and the cooling process in 1758, Benjamin Franklin (1785-1788), governor Pennysylvania, and John Hadley (1731-1764), professor of chemistry at Cambridge commercial soup warmer University have conducted tests and discovered the principle of evaporation. commercial soup warmer Franklin and Haldley confirmed that the evaporation of a liquid such as alcohol or ether can be used to reduce the temperature of an object below the freezing point of water. 2 people have carried out tests using evaporation to lower the temperature of the mercury thermometer from 18 degrees C to -14 degrees C. Franklin noted that soon after crossed the threshold temperature of freezing water, a thin ice film formed on the surface of the thermometer. From there, he came to the conclusion: "The trial shows a man freezing to death right in the summer is done entirely feasible."
Chemists, physicists and British inventor Michael Faraday (1791-1867), the first to perform experiments and liquefied ammonia compressors commercial soup warmer and refrigeration discovered from the opposite process. Arrive in 1820 , chemist and inventor UK, Michael commercial soup warmer Faraday (1791-1867) have made successful experiments with ammonia gas compression and liquefaction. commercial soup warmer He discovered that when the volatile liquid ammonia cooling air can around. More than 20 years later, in 1842, Scottish physician John Gorrie (1803-1855) gas compression commercial soup warmer techniques used to create ice to cool the patients in the hospital in Apalachicola, Florida. commercial soup warmer From that success, he hopes to create an ice machine to cool a building. Even Dr. John envisioned a machine that cooled air for an entire city.
Scottish doctor John Gorrie (1803-1855), who first suggested the idea of the air cooling system. Though models and ideas on've never done, but in 1851, Gorrie was was awarded commercial soup warmer a patent commercial soup warmer for creating ice machine. However, supporters of the project cooler Gorrie died and he could not get the amount of aid to carry out fabrication. commercial soup warmer Even stars that have suffered Gorrie commercial soup warmer opposition from contemporary inventors. Finally, Gorrie died in poverty in 1855 and the idea of a cooler air faded during the next several years.
The model of the ice machine is stored at John Gorrie John Gorrie Museum, Ap
