8-448: Carl Georg Munters (22 March 1897 – 1989) was a Swedish inventor, most known for inventing together with Baltzar von Platen the gas absorption refrigerator now sold by Electrolux . He also invented and patented a method of making foamed plastic, which was later rediscovered by Dow Chemical Company and used to make Styrofoam . He was born in Dala-Järna , Kopparbergs län , Sweden ,
16-476: A thousand patents. Baltzar von Platen (inventor) Baltzar von Platen (24 February 1898 – 29 April 1984) was a Swedish engineer and inventor. Baltzar von Platen born in Malmö , Sweden. He was the son of Philip Ludvig von Platen and Eva Hedvig Ingeborg Ehrenborg. He first studied mathematics, physics, and astronomy at Lund University . Together with inventor and entrepreneur Carl Munters (1897–1989), he
24-614: The Franklin Institute John Price Wetherill Medal in 1932. He was awarded the Adelsköld Medal ( Adelsköldska medaljen ) in gold from the Royal Swedish Academy of Sciences during 1940. Von Platen also worked with ASEA , Sweden's major electrical company, on the development of a process which used heat and pressure to produce diamonds . Von Platen left the project before it succeeded in producing
32-602: The design was improved and their cooling solution was a world sensation. Albert Einstein once mentioned how astonished he was by their ingenious solution. Manufacturing of the refrigerator commenced in 1923 by the company AB Arctic. In 1925, development was finished, and the company was bought by Electrolux. After inventing extruded polystyrene foam plastic in early 1930s and selling his US patent to Dow in 1940s, he started his own company in 1955 and developed, among other things, new insulation materials, air conditioners and dehumidification devices. At his death, Munters had over
40-507: The rights to the Swedish patent for a continuous absorption refrigerator and started to focus on the gas refrigeration market. The company manufactured refrigerators and was the only U.S. manufacturer for many years. Baltzar von Platen and Carl Munters both received the Polhem Prize ( Polhemspriset ) awarded by Swedish Association of Graduate Engineers in 1925. Baltzar von Platen was awarded
48-429: The son of engineer Anders Johan Munters and Hilma Bernhardina Helling. He graduated from KTH in 1922. Munters married Anna Eugenia Geralf in 1925 and Marianne Warkander in 1951. Together with Baltzar von Platen and John Tandberg , Munters invented the gas absorption refrigerator for domestic use. His intention was to create an easy-to-use refrigerator without any moving parts. The technique removed thermal energy, which
56-467: Was driven by a heat source such as propane, electricity, or kerosene. The team rented a room and worked into the night. They slept in the mornings and missed classes at the Royal Institute of Technology where they were students. It took them about a year to create a first prototype that worked with self-circulation. The prototype still had one moving part, a ball valve, and was big and clumsy. Eventually
64-618: Was the inventor of the gas absorption refrigerator in 1922 while they were both Swedish engineering students at the KTH Royal Institute of Technology in Stockholm , Sweden . The Platen-Munters design could operate without a pump. The technique produced "cold" from a heat source such as propane, electricity, or kerosene. In 1923, production by AB Arctic began. In 1925, AB Arctic was purchased by Electrolux , which began selling them worldwide. In 1925, American manufacturer Servel purchased
