Vapor Absorption Refrigeration
An absorption refrigerator is a refrigerator that uses a heat source (e.g., solar energy, a fossil-fueled flame, waste heat from factories, or district heating systems) to provide the energy needed to drive the cooling process. The system uses two coolants, the first of which performs evaporative cooling and is then absorbed into the second coolant; heat is needed to reset the two coolants to their initial states. The principle can also be used to air-condition buildings using the waste heat from a gas turbine or water heater. Using waste heat from a gas turbine makes the turbine very efficient because it first produces electricity, then hot water, and finally, air-conditioning—trigeneration. Absorption refrigerators are commonly used in recreational vehicles (RVs), campers, and caravans because the heat required to power them can be provided by a propane fuel burner, by a low-voltage DC electric heater (from a battery or vehicle electrical system) or by a mains-powered el ...

Refrigerator
A refrigerator, colloquially fridge, is a commercial and home appliance consisting of a thermal insulation, 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. Refrigeration is an essential Food preservation, food storage technique around the world. The lower temperature lowers the reproduction rate of bacteria, so the refrigerator reduces the rate of Food spoilage, spoilage. A refrigerator maintains a temperature a few degrees above the freezing point of water. The optimal temperature range for perishable food storage is .Keep your fridge-freezer clean and ice-free ''BBC''. 30 April 2008 A similar device that maintains a temperature below the freezing point of water is called a freezer. The refrigerator replaced the icebox, which had been a common household appliance for almost a century and a half. The United ...

Travel Trailer
A caravan, travel trailer, camper, tourer or camper trailer is a trailer towed behind a road vehicle to provide a place to sleep which is more comfortable and protected than a tent (although there are fold-down trailer tents). It provides the means for people to have their own home on a journey or a vacation, without relying on a motel or hotel, and enables them to stay in places where none is available. However, in some countries campers are restricted to designated sites for which fees are payable. Caravans vary from basic models which may be little more than a tent on wheels to those containing several rooms with all the furniture and furnishings and equipment of a home. Construction of the solid-wall trailers can be made of metal or fiberglass. Travel trailers are used principally in North America, Europe, Australia and New Zealand. History In Europe, the origins of travel trailers and caravanning can be traced back to the travelling Romani people, and showmen who spe ...

Carl Munters
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. Personal life He was born in Dala-Järna, Kopparbergs län, Sweden, 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. Refrigerators 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 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 mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 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.

Royal Institute Of Technology
The KTH Royal Institute of Technology ( sv, Kungliga Tekniska högskolan, lit=Royal Institute of Technology), abbreviated KTH, is a public research university in Stockholm, Sweden. KTH conducts research and education in engineering and technology and is Sweden's largest technical university. Currently, KTH consists of five schools with four campuses in and around Stockholm. KTH was established in 1827 as the ''Teknologiska institutet (Institute of Technology)'' and had its roots in the ''Mekaniska skolan (School of Mechanics)'' that was established in 1798 in Stockholm. But the origin of KTH dates back to the predecessor of the ''Mekaniska skolan'', the ''Laboratorium mechanicum'', which was established in 1697 by the Swedish scientist and innovator Christopher Polhem. The Laboratorium mechanicum combined education technology, a laboratory, and an exhibition space for innovations. In 1877 KTH received its current name, Kungliga Tekniska högskolan (KTH Royal Institute of Tech ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferdinand Carré
Ferdinand Philippe Edouard Carré (11 March 1824 – 11 January 1900) was a French engineer, born at Moislains (Somme) on 11 March 1824. Carré is best known as the inventor of refrigeration equipment used to produce ice. He died on 11 January 1900 at Pommeuse (Seine-et-Marne). Work In 1850, Ferdinand's brother Edmond Carré (22 January 1833 – 7 May 1894) developed the first absorption refrigerator, using water and sulphuric acid. Ferdinand continued Edmond's work on the process and in 1858 developed a machine which used water as the absorbent and ammonia as refrigerant. His absorption machine was patented in France in 1859 and in the United States in 1860. In 1862 he exhibited his ice-making machine at the Universal London Exhibition, producing an output of per hour. His design was based on the gas–vapour system of Australian inventor James Harrison. In 1876 he equipped the ship ''Paraguay'' with an absorption refrigeration system, allowing the ship to carry frozen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
