Air Conditioning Systems Throughout Time - A Brief Overview

It is a wonderful thing to be able to flip a switch

, and have an entire room cooled off through air conditioning. Portable room air conditioners make sense when you wish to cool certain parts of your home, office, or covered outdoor living spaces. Air conditioning is commonly found in buildings today, but it was not always the case throughout history.

Well off ancient Egyptian families could enjoy the cooling benefits brought from aqueduct water that spanned the insides of walls in buildings. Water was a costly commodity in that hot area of the planet, so only the wealthy could afford this luxurious. Medieval Persians employed wind towers and cisterns to cool down their buildings. Wind would be captured in the wind tower, which was then directed over the water in the open cistern, which would vaporize and chill the background temperature within the dwelling.

Later the concept that liquefied ammonia, when it evaporated, could chill the air was thought up by UK scientist Michael Faraday in 1820. In America in 1842, Dr. John Gorrie made a machine to make ice, and he exploited the ice to chill the air in his surgery in Florida.

Industry was the most important reason that air conditioners were made round the turn of the prior century in the U. S. . Willis Haviland Carrier made the first electric air conditioner in 1902, which was used to cool down and dehumidify the air in a printing plant. The term "aircon" was coined by American Stuart W. Cramer in 1906, who popped up with a technique to add moisture to the air, which was critical in his textile producing mill.

Noxious gases were used to run the early air conditioners, but Thomas Midgley, Jr. Made Freon refrigerant in 1928. Unfortunately, he didn't know that Freon isn't very good for the ozone, and lately more recent refrigerants have been developed that are much safer for the environment.

Aircon isn't just used today to make our houses and other buildings more at ease. You'll find air-con employed in land, water and space cars. Air-conditioning is used to also filter bad particles in the air , for example in hospital operating rooms. If you have allergies or asthma, aircon can help take away the pollen, dander and dust that causes these conditions to flare up.

The old may also be in peril if they're in a too-hot building, so aircon can be vital for their well being. Some air conditioners are also dehumidifiers, which take the surplus moisture out of the air to make you more at ease re your temperature. Today we are fortunate that a great air conditioner is your answer for cooling comfort.
