Industrial needs led to the invention of the first air conditioner and this was done by Willis Havilland Carrier whose invention in the year 1902 helped in cooling as well as humidifying the air inside a printers plants. It was a person called Stuart W. Cramer who actually first coined the term air conditioning and it referred to a method of adding moisture to the air in order to cool the atmosphere.In the earliest air conditioners, toxic gases would be used but it was a person called Thomas Midgley Jr. Who created, in the year 1928 the first Freon refrigerant. Though this was a major discovery at the time, now we realize that Freon is bad for the Ozone layer.

There are however other uses as well including being used to filter out harmful particles from the air and this kind of usage are is widely applied in operation theaters in hospitals.Air conditioning can also be used to help people overcome allergies. This is because an air conditioner can also help in the removal of pollen and dander as well as dust which are the reasons why people suffer from allergies of different kinds.There are a few air conditioner models that can also act as dehumidifiers and such models are able to remove the unwanted excessive moisture out of the air and this will make the room much more comfortable. We can certainly thank our lucky stars that some inventive geniuses found out how to air condition our homes and offices!
