Food in a refrigerator with its door open. A refrigerator, commonly shortened to fridge, is a commercial and home appliance consisting of a thermally insulated compartment and a heat pump (mechanical, electronic or chemical) that transfers heat from its inside to its external environment so that its inside is cooled to a temperature below the room temperature.

Harrison is also remembered as the inventor of the mechanical refrigeration process creating ice and founder of the Victorian Ice Works and as a result, is often called "the father of refrigeration". [2] In 1873 he won a gold medal at the Melbourne Exhibition by proving that meat kept frozen for months remained perfectly edible. [1]
He soon made himself known with a variety of useful mechanical inventions [1] and eventually had twenty-one American and nineteen English patents.Sometimes known as the father of the refrigerator. [2] He was elected a Fellow of the American Academy of Arts and Sciences in 1813 and a member of the American Philosophical Society in 1819. [3] [4]
The Einstein–Szilard or Einstein refrigerator is an absorption refrigerator which has no moving parts, operates at constant pressure, and requires only a heat source to operate. It was jointly invented in 1926 by Albert Einstein and his former student Leó Szilárd , who patented it in the U.S. on November 11, 1930 ( U.S. patent 1,781,541 ).
Frederick McKinley Jones (May 17, 1893 – February 21, 1961) was an American inventor, entrepreneur, engineer, winner of the National Medal of Technology, and an inductee of the National Inventors Hall of Fame. [1] He innovated mobile refrigeration technology.
With the invention of synthetic refrigerants based mostly on a chlorofluorocarbon (CFC) chemical, safer refrigerators were possible for home and consumer use. Freon led to the development of smaller, lighter, and cheaper refrigerators. The average price of a refrigerator dropped from $275 to $154 with the synthesis of Freon.
John B. Gorrie (October 3, 1803 – June 29, 1855) was a Nevisian-born American physician and scientist, credited as the inventor of mechanical refrigeration. [1] [2]Born on the Island of Nevis in the Leeward Islands of the West Indies to Scottish parents on October 3, 1803, he spent his childhood in South Carolina.
Carl Paul Gottfried von Linde (11 June 1842 – 16 November 1934) was a German scientist, engineer, and businessman. He discovered the refrigeration cycle and invented the first industrial-scale air separation and gas liquefaction processes, which led to the first reliable and efficient compressed-ammonia refrigerator in 1876.
