In 1820, a British scientist revealed that when ammonia was compressed and liquefied at the same time would result in cool air being generated when the liquefied ammonia dispersed. In America during the year 1842, John Gorrie used compressor technology in an amazing new way and created ice. He used this ice to cool the room air for his hospital patients.
He desired to eventually utilise his machine to control the temperature of structures. He even dreamt of creating entire cities with a system of centralised air conditioning. Even though the original prototype was a machine that leaked and produced shabby results at best, it was still granted a patent in the year 1851.
Early industrial use of air conditioning was to cool air for the needs of industrial products as opposed to personal comfort. In the year, 1902, Willis Haviland Carrier in the state of New York invented the pioneering modern electrical air conditioning system. This system was designed in order to facilitate manufacturing process control in a printing plant.
This version of the air conditioning system invented by him could manipulate temperature as well as humidity. As a result of the cooling air, the printing machines were able to achieve higher levels of efficiency and achieve unprecedented levels of economies of scale. It was only after this industrial application of air conditioning systems, that air conditioning units began to find their way into homes, offices, and eventually, automobiles.
