Absorption cooling was invented by the French scientist Ferdinand Carré in 1858. The original design used water and sulphuric acid. In 1922, two students at the Royal Institute of Technology in Stockholm, Sweden, Baltzar von Platen and Carl Munters, enhanced the principle with a three-fluid configuration. This "Platen-Munters" design can operate without a pump.
