This work of energy transfer is traditionally driven by Refrigeration has had a large impact on industry, lifestyle, agriculture, and settlement patterns. The idea of preserving food dates back to human mechanical refrigeration was developed, improved, and greatly expanded in its reach. Refrigeration has thus rapidly evolved in the past century, from These new settlement patterns sparked the building of large cities which are able to thrive in areas that were otherwise thought to be inhospitable, such as History [ ] Before 1830, few Americans used ice to refrigerate foods due to a lack of ice-storehouses and iceboxes. As these two things became more widely available, individuals used axes and saws to Despite the difficulties of harvesting ice, Frederic Tudor thought that he could capitalize on this new commodity by harvesting ice in New England and shipping it to the Caribbean islands as well as the southern states. In the begi...

American inventor Florence Wilhelmina Florence Parpart, was an American inventor known primarily for her patents for an industrial Personal life [ ] Biographies frequently claim that little is known of Parpart's life, describing her simply as being described on census data as a housewife or as the inventor of the refrigerator. Although Parpart's birthplace is often given as Parpart's family may have been wealthy. Upon her father's death in 1900, she was supposedly left "a legacy of $10,000." Parpart was trained as a stenographer While at Eastern Sanitary, Parpart also met her future husband Hiram D. Layman, who was the company's general manager. The couple were married at her mother's home in New York on July 5, 1903. Patent filings show that the Laymans moved several times between 1900 and 1919. Their residence is listed as Parpart appears to have continued living in Pittsburgh until Hiram D. Layman's death in June 1919, Patents [ ] Street sweeper [ ] The first invention credited to Parpart is a street sweeper designed to automate the process of cleaning city streets. Parpart filed two patents for this invention (No. 649,609 The sweeper was designed to reduce the manual labor involved in street sweeping by providing an automated mechanism to "efficiently gather dirt from the street-surface regardless of inequalities" and deliver the dirt by an onboard elevator to a storage receptacle that could then discharge it into carts. According to advertisements from the time period...

Thomas Midgley Inventions through history have often made everyday tasks easier and some, like trains, the Thomas Midgley, Jr. introduced the world to both leaded gasoline and chlorofluorocarbons (CFCs), now considered two of the world’s most harmful chemical compounds. While Midgley won multiple prestigious awards during his lifetime, research in recent decades has shown how the compounds he developed for use in cars and refrigerators ended up ravaging the environment and poisoning people. WATCH: Midgley, born on May 18, 1889, graduated with a degree in mechanical engineering from Cornell University in 1911. In 1916, he joined General Motor’s Delco research laboratory under Knock was a common problem in early 20 century engines. When an engine neared its maximum load, it made pinging noises that could destroy it. After a lengthy study, Midgley discovered that tetraethyl lead (TEL) as a fuel additive virtually eliminated knock. Even better, he found that TEL increased engine performance and speed. With the support of GM, oil companies, and car manufacturers, TEL went on the market on February 1, 1923 under the brand name Ethyl. GM and Standard Oil formed the Ethyl Corporation to handle manufacturing and sales. Midgley became a vice president and served on the board of directors. The Ethyl Corporation never mentioned “lead” when marketing TEL since the dangers of lead poisoning were well known. The corporation insisted that TEL was safe, but, at the same time, encountered t...

(1893-1961) Who Was Frederick Jones? After a challenging childhood, Frederick Jones taught himself mechanical and electrical engineering, inventing a range of devices relating to refrigeration, sound and automobiles. Portable refrigeration units developed by Jones helped the United States military carry food and blood during World War II. Early Life Frederick McKinley Jones was born in Cincinnati, Ohio, on May 17, 1893 to a white father and black mother. His mother deserted him when he was a young child. His father struggled to raise him on his own, but by the time Frederick was 7 years old, he sent young Jones to live with a priest in Kentucky. Two years later, his father died. This living situation lasted for two years. At the age of 11, with minimal education under his belt, Jones ran away to fend for himself. He returned to Cincinnati and found work doing odd jobs, including as a janitor in a garage where he developed a knack for automobile mechanics. He was so good, he became foreman of the shop. He later moved on, again taking odd jobs where he could. In 1912, he landed in Hallock, Minnesota, where he obtained a job doing mechanical work on a farm. Inventions Jones had talent for and an interest in mechanics. He read extensively on the subject in addition to his daily work, educating himself in his spare time. By the time he was twenty, Jones was able to secure an engineering license in Minnesota. He served in the U.S. Army during World War I where he was often calle...

A. Norwegian icebox. The ice was placed in the drawer at top. B. Typical Victorian icebox, of oak with tin or zinc shelving and door lining. C. An oak cabinet icebox that would be found in well-to-do homes. The icebox was invented by an American farmer and cabinetmaker named Thomas Moore in 1802. Ice collection and distribution [ ] Underground pits with the constant underground temperature of 12°C (54°F) had been used since Roman times to help preserve ice collected during winter. By 1781, personal ice pits were becoming more advanced. The Robert Morris Impact and legacy [ ] As the techniques for food preservation steadily improved, prices decreased and food became more readily available. Scientific American, a popular science magazine. Schooley described the process as "Combining an ice receptacle with the interior of a refrigerator … a continuous circulation of air shall be kept up through the ice in said receptacle and through the interior of the refrigerator … so that the circulation air shall deposit its moisture on the ice every time it passes through it, and be dried and cooled." By the early 1930s, mechanical ice machines gradually began to rise over the ice harvesting industry thanks to its ability to produce clean, sanitary ice independently and year-round. Over time, as the mechanical ice machines became smaller, cheaper, and more efficient, they easily replaced the hassle of getting ice from a source. For example, the De La Vergne Refrigerating Machine Company ...

If you’ve ever been without power in your house, you know just how suddenly keeping the food in the refrigerator cold becomes a necessity. Can you imagine living in a time before refrigerators? Warm summer months meant that families would gamble with safe food consumption, and any families living in poverty were rarely able to afford ice. From ancient ice houses to today’s Internet-connected fridges – take a tour through the history and development of the refrigerator. What is the First and Oldest Refrigerator in the World? Scientists ind the world continue to argue about the world's first refrigerator. However, most scientists recognize that the first real electric refrigerator used in the home was the Domelre, born in 1913 by the American inventor. Since ancient times, the inhabitants of temperate regions had the idea of ​​​​preserving food in a cold environment. Scientists discovered that a few thousand years ago, Turkish kings loved to eat "sherbet", a type of syrup with added snow. In the days of Alexander the Great, it was known to chill fruit in the snow. In China, frozen fruit juices have been popular since the 12th century. Thus, the idea of ​​​​creating a cold environment to preserve food has been around since ancient times, but it was not until the 18th century that people could implement this idea by placing it in a closed cabinet. ice cubes and change them often to keep food longer. Natural ice was an important commercial commodity until the early twentieth ce...

The refrigerators of the 1920s were deadly. Their motorized compressors easily malfunctioned, allowing the refrigerants—that is, toxic gases—to escape and sicken or kill whole families in their sleep. Albert Einstein and his colleague Leo Szilard, physicists at the University of Berlin, took the matter in hand in 1926 and invented a pump to replace the refrigerator’s motorized compressor. The device, hermetically sealed and with no moving parts, relied on Einstein and Szilard’s cutting-edge research in electromagnetism and thermodynamics. Einstein and Szilard received a US patent for their new apparatus and method of refrigeration on November 11, 1930, and yet, after seven years of hard work, they were unable to commercialize their invention. Some of their difficulties are familiar to inventors today: rival innovations in foreign countries and insufficient support from investors at home, to name two obstacles. Others are less familiar: total economic collapse and widespread political violence. Reinventing the Refrigerator Einstein and Szilard had met in the early 1920s, when Szilard was still a physics doctoral candidate at the University of Berlin. On the faculty there, Einstein supported Szilard’s academic work but advised him to do something practical—ideally, pick up a patent or several. (Einstein was a passionate inventor and erstwhile patent examiner.) The Einstein-Szilard pump and refrigeration system, In 1926, the pair started working together on a solution to the ...

Every home has a refrigerator these days and for good reason. Refrigerators keep your food cool, which helps prevent it from spoiling. In fact, you might not even be able to imagine life without them. You don't have to go far back in history to see when they were first invented, but you may be surprised by who invented the refrigerator and how long it took them. Let's figure it out now. In 1805, American inventor Oliver Evans designed the first chiller that did not use steam and instead used steam for cooling. In 1834, Jacob Perkins practically produced the first cooler, and in 1844, American doctor John Gorrie built a refrigerator based on Oliver Evans' design to producing ice to cool the air for patients with yellow fever. Following the successes of their predecessors, ice machines for practical food purposes such as meat packing and brewing were invented by James Harrison in 1857. The concept was taken. more elaborated in 1859 by Ferdinand Carre. The newly developed system works by not using compressed air for cooling, using ammonia instead. Then, in 1876, Carl von Linden, a German engineer, established gas liquefaction - an important aspect of refrigeration technology. In 1913, the refrigerator used in the home was invented. In 1923 Frigidaire introduced the first self-contained units. Starting in the 1920s Freon – colorless, odorless, non-harmful refrigerants were introduced into the market to replace substances previously used. The first widely used system was releas...
