Refrigeration is any of various types of cooling of a space, substance, or system to lower and/or maintain its temperature below the ambient one (while the removed heat is ejected to a place of higher temperature). [1][2] Refrigeration is an artificial, or human-made, cooling method. [1][2] Refrigeration refers to the process by which energy ...
Globally. Food in a refrigerator with its door open. A refrigerator, commonly 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 ...
Icebox. An icebox (also called a cold closet) is a compact non-mechanical refrigerator which was a common early-twentieth-century kitchen appliance before the development of safely powered refrigeration devices. Before the development of electric refrigerators, iceboxes were referred to by the public as "refrigerators".
An absorption refrigerator is a refrigerator that uses a heat source to provide the energy needed to drive the cooling process. Solar energy, burning a fossil fuel, waste heat from factories, and district heating systems are examples of convenient heat sources that can be used. An absorption refrigerator uses two coolants: the first coolant ...
Jacob Perkins (July 9, 1766 – July 30, 1849) was an American inventor, mechanical engineer and physicist based in the United Kingdom. Born in Newburyport, Massachusetts, Perkins was apprenticed to a goldsmith. He soon made himself known with a variety of useful mechanical inventions [1] and eventually had twenty-one American and nineteen ...
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.

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.
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).
