When was the icemachine invented?
Dr. John Gorrie, an early pioneer
in the invention of the artificial manufacture of ice, refrigeration, and air
conditioning, was granted the first U.S. Patent for mechanical refrigeration in
1851. Dr. Gorrie's basic principle is the one most often used in refrigeration
today; namely, cooling caused by the rapid expansion of gases. Using two double
acting force pumps he first condensed and then rarified air. His apparatus,
initially designed to treat yellow fever patients, reduced the temperature of
compressed air by interjecting a small amount of water into it. The compressed
air was submerged in coils surrounded by a circulating bath of cooling water. He
then allowed the interjected water to condense out in a holding tank,
andreleased or rarified, the compressed air into a tank of lower pressure
containing brine; This lowered the temperature of the brine to 26 degrees F. or
below, and immersing drip-fed, brick-sized, oil coated metal containers of
non-saline water, or rain water, into the brine, manufactured ice bricks. The
cold air was released in an open system into the atmosphere.
