their homes. Air conditioning units initially began to be used in 1902, but weren’t officially called “air

conditioners” until 1906, by Stuart Cramer (Air Conditioning and Refrigeration Timeline). Until the

20th century people tried to obtain air conditioning by doing things such as draping saturated mats in

doorways and installing water powered fans. Leonardo DeVinci built a mechanical ventilating fan which

The cycle that air goes through before it enters your home is called the Refrigeration Cycle.

The definition of the refrigeration cycle is; a sequence of thermodynamic processes whereby heat is

withdrawn from a cold body and expelled to a hot body. The refrigeration cycle is composed of nine

different equally important components which are: two fans, a liquid line, a suction line, a compressor,

a condenser, an evaporator coil, a metering device, and a filter for the filtration of the air that flows into

the home.

Willis Haviland Carrier’s creation of the air conditioning unit was the launch of the modern idea.

But it was because of Benjamin franklin and John Hadley, who originally discovered that the evaporation

of alcohol and other volatile liquids evaporated could cool an object enough to freeze water.
