Einstein Refrigerator

Heating and Cooling

The Einstein refrigerator, also called the Einstein-Szilárd refrigerator, is an absorption refrigerator with no moving parts that operates at constant pressure and needs only a heat source to run. It was invented jointly in 1926 by Albert Einstein and his former student Leo Szilárd, who patented the design in the United States on November 11, 1930. The device uses three working fluids, water, ammonia and butane, and was itself a modification of an earlier three-fluid absorption design created by the Swedish engineers Baltzar von Platen and Carl Munters, which was later commercialized by Electrolux.
