Perkins is credited with the first patent for the vapor-compression refrigeration cycle, assigned on August 14, 1834 [11] and titled, "Apparatus and means for producing ice, and in cooling fluids". The idea had come from another American inventor, Oliver Evans , who conceived of the idea in 1805 but never built a refrigerator.
1834 – Ideal gas law by Émile Clapeyron; 1834 – Émile Clapeyron characterizes phase transitions between two phases in form of Clausius–Clapeyron relation. 1834 – Jacob Perkins obtained the first patent for a vapor-compression refrigeration system. 1834 – Jean-Charles Peltier discovers the Peltier effect
In 1820, the British scientist Michael Faraday liquefied ammonia and other gases by using high pressures and low temperatures, and in 1834, an American expatriate in Great Britain, Jacob Perkins, built the first working vapor-compression refrigeration system.
In 1820, the English scientist Michael Faraday liquefied ammonia and other gases by using high pressures and low temperatures, and in 1834, an American expatriate to Great Britain, Jacob Perkins, built the first working vapor-compression refrigeration system in the world. It was a closed-cycle that could operate continuously, as he described in ...
1834 Jacob Perkins patents a design for a practical refrigerator using dimethyl ether. [13] 1852 Lord Kelvin describes the theory underlying heat pumps. [14] 1855–1857 Peter von Rittinger develops and builds the first heat pump. [15] 1877
In 1834, Jacob Perkins modified Evans' original design, building the world's first refrigerator and filing the first legal patent for refrigeration using vapor-compression. [48] John Gorrie , an American doctor from Florida , invented the first mechanical refrigeration unit in 1841, based on Evans' original invention to make ice in order to ...
1834 – Jacob Perkins, obtained the first patent for a vapor-compression refrigeration system. 1850s – Rudolf Clausius sets out the concept of the thermodynamic system and positioned entropy as being that in any irreversible process a small amount of heat energy δQ is incrementally dissipated across the system boundary
