Jones designed the portable air-cooling unit for trucks carrying perishable food to prevent spoilage. [11] [14] The Model A refrigeration equipment was attached to undercarriages of trucks. Chilled air was transported to the inside of the trailer via refrigerant tubing. [17] Because Model A was too heavy, Jones later developed the Model B.
It consisted of a new style of heat exchanger in a sheet metal cabinet—a highly efficient, lightweight replacement for the bulky, slow-responding castiron radiator. In 1931, The Trane Company developed its first air conditioning unit, the Trane unit cooler, and in 1938 its first centrifugal refrigeration machine, the Turbovac.
The heating radiator was invented by Franz San Galli in 1855, a Kingdom of Prussia-born Russian businessman living in St. Petersburg. [2] [3] In the late 1800s, companies, such as the American Radiator Company, promoted cast iron radiators over previous fabricated steel designs in order to lower costs and expand the market.
The Roman hypocaust is an early example of a type of radiator for building space heating. Franz San Galli, a Prussian-born Russian businessman living in St. Petersburg, is credited with inventing the heating radiator around 1855, [1] [2] having received a radiator patent in 1857, [3] but American Joseph Nason and Scot Rory Gregor developed a primitive radiator in 1841 [4] and received a number ...
Thomas Midgley Jr. (May 18, 1889 – November 2, 1944) was an American mechanical and chemical engineer.He played a major role in developing leaded gasoline (tetraethyl lead) and some of the first chlorofluorocarbons (CFCs), better known in the United States by the brand name Freon; both products were later banned from common use due to their harmful impact on human health and the environment.
Despite its name, a radiator does not primarily heat a room by radiation. If positioned correctly a radiator will create an air convection current in the room, which will provide the main heat transfer mechanism. It is generally agreed that for the best results a steam radiator should be no more than one to two inches (2.5 to 5cm) from a wall.
However, before air conditioning existed, people had to be creative when trying to stay comfortable in sweltering conditions. Here are five different ways people across the United States beat the ...
Jacob Perkins invented an ice-making machine that used ether in 1843, and Edmond Carré built a refrigerator that used water and sulfuric acid in 1850. In Japan, Fusanosuke Kuhara, founder of Hitachi, Ltd., made an air conditioner for his own home use using compressed CO 2 as a refrigerant in 1917. [99]
