116-663: The group met at the Gillis Tavern to lay down the rules of the organization. Thirty years later, the group would again make Canadian sports history, by building Canada's first indoor ice rink . In addition to its status as the oldest curling club on the continent, the Royal Montreal Curling Club is also the oldest active sports club in North America. This curling -related article is a stub . You can help Misplaced Pages by expanding it . This Montreal -related article

232-420: A Scottish word meaning 'course', was used as the name of a place where curling was played. As curling is played on ice, the name has been retained for the construction of ice areas for other sports and uses. Early attempts in the construction of artificial ice rinks were first made in the 'rink mania' of 1841–44. The technology for the maintenance of natural ice did not exist, therefore these early rinks used

348-634: A coolant produces cold temperatures underneath the water body(on which the game is played), causing the water body to freeze and then stay frozen. There are also synthetic ice rinks where skating surfaces are made out of plastics. Besides recreational ice skating, some of its uses include: ice hockey, sledge hockey ( a.k.a. "Para ice hockey", or "sled hockey"), spongee ( a.k.a. sponge hockey), bandy , rink bandy , rinkball , ringette , broomball (both indoor and outdoor versions), Moscow broomball , speed skating , figure skating , ice stock sport , curling, and crokicurl . However, Moscow broomball

464-435: A "cooling culture" as majority of people used ice and iceboxes to store their dairy products, fish, meat, and even fruits and vegetables. These early cold storage practices paved the way for many Americans to accept the refrigeration technology that would soon take over the country. The history of artificial refrigeration began when Scottish professor William Cullen designed a small refrigerating machine in 1755. Cullen used

580-463: A 1.7% increase in dairy consumption and overall protein intake by 1.25% annually in the US after the 1890s. People were not only consuming these perishables because it became easier for they themselves to store them, but because the innovations in refrigerated transportation and storage led to less spoilage and waste, thereby driving the prices of these products down. Refrigeration accounts for at least 5.1% of

696-453: A cold climate, indoors or outdoors, although both types are of frozen water. A more proper technical term is 'mechanically frozen' ice. An example of this type of rink is the outdoor rink at Rockefeller Center in New York . Modern rinks have a specific procedure for preparing the surface. With the pipes cold, a thin layer of water is sprayed on the sand or concrete to seal and level it (or in

812-454: A company acquired by the W.C. Bradley Co., which went on to produce the first commercial ice-makers in the US. By the 1870s, breweries had become the largest users of harvested ice. Though the ice-harvesting industry had grown immensely by the turn of the 20th century, pollution and sewage had begun to creep into natural ice, making it a problem in the metropolitan suburbs. Eventually, breweries began to complain of tainted ice. Public concern for

928-470: A concentration of business, shopping, and entertainment outside a traditional downtown or central business district in what had previously been a residential or rural area. There were several factors contributing to the growth of these cities such as Los Angeles, Las Vegas, Houston, and Phoenix. The factors that contributed to these large cities include reliable automobiles, highway systems, refrigeration, and agricultural production increases. Large cities such as

1044-589: A demand for New Zealand meat around the world. In order to meet this new demand, the farmers improved their feed so sheep could be ready for the slaughter in only seven months. This new method of shipping led to an economic boom in New Zealand by the mid 1890s. In the United States, the Meat Inspection Act of 1891 was put in place in the United States because local butchers felt the refrigerated railcar system

1160-462: A few years, 300,000 people in rural areas of the United States had received power in their homes. While electricity dramatically improved working conditions on farms, it also had a large impact on the safety of food production. Refrigeration systems were introduced to the farming and food distribution processes, which helped in food preservation and kept food supplies safe . Refrigeration also allowed for shipment of perishable commodities throughout

1276-483: A greater variety of crops, fertilizers, pesticides, and improved technology. Improved technology has decreased the risk and time involved for agricultural management and allows larger farms to increase their output per person to meet society's demand. Prior to 1882, the South Island of New Zealand had been experimenting with sowing grass and crossbreeding sheep, which immediately gave their farmers economic potential in

1392-496: A horse-drawn ice cutter in 1825. This invention as well as Tudor's success inspired others to get involved in the ice trade and the ice industry grew. Ice became a mass-market commodity by the early 1830s with the price of ice dropping from six cents per pound to a half of a cent per pound. In New York City, ice consumption increased from 12,000 tons in 1843 to 100,000 tons in 1856. Boston's consumption leapt from 6,000 tons to 85,000 tons during that same period. Ice harvesting created

1508-518: A lack of ice-storehouses and iceboxes. As these two things became more widely available, individuals used axes and saws to harvest ice for their storehouses. This method proved to be difficult, dangerous, and certainly did not resemble anything that could be duplicated on a commercial scale. 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

1624-475: A larger concentration of agricultural sales coming from a smaller percentage of farms. Farms today have a much larger output per person in comparison to the late 1800s. This has resulted in new food sources available to entire populations, which has had a large impact on the nutrition of society. The seasonal harvesting of snow and ice is an ancient practice estimated to have begun earlier than 1000 BC. A Chinese collection of lyrics from this time period known as

1740-450: A man to death on a warm summer's day". In 1805, American inventor Oliver Evans described a closed vapor-compression refrigeration cycle for the production of ice by ether under vacuum. 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

1856-570: A pit called a Yakhchal and may have been the first group of people to use cold storage to preserve food. In the Australian outback before a reliable electricity supply was available many farmers used a Coolgardie safe , consisting of a room with hessian (burlap) curtains hanging from the ceiling soaked in water. The water would evaporate and thereby cool the room, allowing many perishables such as fruit, butter, and cured meats to be kept. Before 1830, few Americans used ice to refrigerate foods due to

1972-458: A properly built space. This consists of a bed of sand or occasionally a slab of concrete , through (or on top of) which pipes run. The pipes carry a chilled fluid (usually either a salt brine or water with antifreeze , or in the case of smaller rinks, refrigerant ) which can lower the temperature of the slab so that water placed atop will freeze. This method is known as 'artificial ice' to differentiate from ice rinks made by simply freezing water in

2088-524: A pump to create a partial vacuum over a container of diethyl ether , which then boiled , absorbing heat from the surrounding air. The experiment even created a small amount of ice, but had no practical application at that time. In 1758, Benjamin Franklin and John Hadley , professor of chemistry, collaborated on a project investigating the principle of evaporation as a means to rapidly cool an object at Cambridge University , England . They confirmed that

2204-617: A refrigerant worldwide was curtailed in the Montreal Protocol of 1987. In the last century, refrigeration allowed new settlement patterns to emerge. This new technology has allowed for new areas to be settled that are not on a natural channel of transport such as a river, valley trail or harbor that may have otherwise not been settled. Refrigeration has given opportunities to early settlers to expand westward and into rural areas that were unpopulated. These new settlers with rich and untapped soil saw opportunity to profit by sending raw goods to

2320-434: A solid polymer material designed for skating using normal metal-bladed ice skates. High density polyethelene (HDPE) and ultra-high molecular weight polyethylene (UHMW) are the only materials that offer reasonable skating characteristics, with UHMW synthetic rinks offering the most ice-like skating but also being the most expensive. A typical synthetic rink will consist of many panels of thin surface material assembled on top of

2436-417: A solution of glycerine with ether , nitrogen peroxide and water . The pipes were covered by water and the solution was pumped through, freezing the water into ice . Gamgee discovered the process while attempting to develop a method to freeze meat for import from Australia and New Zealand , and patented it as early as 1870. Gamgee operated the rink on a membership-only basis and attempted to attract

2552-423: A sturdy, level and smooth sub-floor (anything from concrete to wood or even dirt or grass) to create a large skating area. Periodically after the ice has been used, it is resurfaced using a machine called an ice resurfacer (sometimes colloquially referred to as a Zamboni – referring to a major manufacturer of such machinery). For curling, the surface is 'pebbled' by allowing loose drops of cold water to fall onto

2668-558: A substitute consisting of a mixture of hog's lard and various salts. An item in the May 8, 1844 issue of Eliakim Littell 's Living Age headed "The Glaciarium" reported that "This establishment, which has been removed to Grafton street East' Tottenham Court Road , was opened on Monday afternoon. The area of artificial ice is extremely convenient for such as may be desirous of engaging in the graceful and manly pastime of skating". By 1844, these venues fell out of fashion as customers grew tired of

2784-636: A triumph over physical difficulties, as would have been incredible, even unimaginable, a very few days ago...". The Marlborough —sister ship to the Dunedin – was immediately converted and joined the trade the following year, along with the rival New Zealand Shipping Company vessel Mataurua , while the German Steamer Marsala began carrying frozen New Zealand lamb in December 1882. Within five years, 172 shipments of frozen meat were sent from New Zealand to

2900-748: A wealthy clientele, experienced in open-air ice skating during winters in the Alps . He installed an orchestra gallery, which could also be used by spectators, and decorated the walls with views of the Swiss Alps . The rink initially proved a success, and Gamgee opened two further rinks later in the year: at Rusholme in Manchester and the "Floating Glaciarium" at Charing Cross in London, this last significantly larger at 35.1 by 7.6 metres (115 by 25 ft). The Southport Glaciarium opened in 1879, using Gamgee's method. In

3016-415: Is 3 to 5 °C (37 to 41 °F). In commerce and manufacturing, there are many uses for refrigeration. Refrigeration is used to liquefy gases – oxygen , nitrogen , propane , and methane , for example. In compressed air purification, it is used to condense water vapor from compressed air to reduce its moisture content. In oil refineries , chemical plants , and petrochemical plants, refrigeration

Ice rink An ice rink (or ice skating rink ) is a frozen body of water or an artificial sheet of ice where people can ice skate or play winter sports . Ice rinks are also used for exhibitions, contests and ice shows. The growth and increasing popularity of ice skating during

3248-589: Is an artificial, or human-made, cooling method. Refrigeration refers to the process by which energy, in the form of heat, is removed from a low-temperature medium and transferred to a high-temperature medium. This work of energy transfer is traditionally driven by mechanical means (whether ice or electromechanical machines), but it can also be driven by heat, magnetism , electricity , laser , or other means. Refrigeration has many applications, including household refrigerators , industrial freezers , cryogenics , and air conditioning . Heat pumps may use

3364-518: Is critical. The popularity of the sport of hockey in Canada has led its icemakers to be particularly sought after. One such team of professionals was responsible for placing a loonie coin under center ice at the 2002 Winter Olympics in Salt Lake City, Utah ; as both Canadian teams (men's and women's) won their respective hockey gold medals, the coin was christened "lucky" and is now in the possession of

3480-593: Is located on the campus of Northeastern University . This American rink is the original home of the National Hockey League (NHL) Boston Bruins . The Bruins are the only remaining NHL team who are members of the NHL's Original Six with their original home arena still in existence. The Guidant John Rose Minnesota Oval is an outdoor ice rink in Roseville, Minnesota , that is large enough to allow ice skaters to play

3596-471: Is supplied from a high-temperature source to the engine, part of the heat being used to produce work and the rest being rejected to a low-temperature sink. This satisfies the second law of thermodynamics . A refrigeration cycle describes the changes that take place in the refrigerant as it alternately absorbs and rejects heat as it circulates through a refrigerator . It is also applied to heating, ventilation, and air conditioning HVACR work, when describing

3712-440: Is typically played on a tarmac tennis court that has been flooded with water and allowed to freeze. The sports of broomball, curling, ice stock sport, spongee, Moscow broomball, and the game of crokicurl, do not use ice skates of any kind. While technically not an ice rink, ice tracks and trails , such as those used in the sport of speed skating and recreational or pleasure skating are sometimes referred to as "ice rinks". Rink ,

3828-403: Is used to cool the ice down further (as in a traditional ice-cream maker ). Dry ice can reliably bring the temperature well below water freezing point. This consists of a refrigeration cycle, where heat is removed from a low-temperature space or source and rejected to a high-temperature sink with the help of external work, and its inverse, the thermodynamic power cycle . In the power cycle, heat

3944-454: Is used to maintain certain processes at their needed low temperatures (for example, in alkylation of butenes and butane to produce a high- octane gasoline component). Metal workers use refrigeration to temper steel and cutlery. When transporting temperature-sensitive foodstuffs and other materials by trucks, trains, airplanes and seagoing vessels, refrigeration is a necessity. Dairy products are constantly in need of refrigeration, and it

4060-537: The Sleaping , describes religious ceremonies for filling and emptying ice cellars. However, little is known about the construction of these ice cellars or the purpose of the ice. The next ancient society to record the harvesting of ice may have been the Jews in the book of Proverbs, which reads, "As the cold of snow in the time of harvest, so is a faithful messenger to them who sent him." Historians have interpreted this to mean that

4176-569: The British Isles . Although not actually the first to achieve successful transportation of frozen goods overseas (the Strathleven had arrived at the London docks on 2 February 1880 with a cargo of frozen beef, mutton and butter from Sydney and Melbourne ), the breakthrough is often attributed to William Soltau Davidson , an entrepreneur who had emigrated to New Zealand . Davidson thought that Britain's rising population and meat demand could mitigate

4292-480: The Hockey Hall of Fame after having been retrieved from beneath the ice. In bandy , the size of the playing field is 90–110 m (300–360 ft) x 45–65 m (148–213 ft). For internationals, the size must not be smaller than 100 m × 60 m (330 ft × 200 ft). The variety rink bandy is played on ice hockey rinks . The size of figure skating rinks can be quite variable, but

4408-500: The International Skating Union prefers Olympic-sized rinks for figure skating competitions, particularly for major events. These are 60 by 30 m (197 by 98 ft). The ISU specifies that competition rinks must not be larger than this and not smaller than 56 by 26 m (184 by 85 ft). Although there is a great deal of variation in the dimensions of actual ice rinks, there are basically two rink sizes in use at

4524-631: The sushi / sashimi industry in Japan. Before the discovery of refrigeration, many sushi connoisseurs were at risk of contracting diseases. The dangers of unrefrigerated sashimi were not brought to light for decades due to the lack of research and healthcare distribution across rural Japan. Around mid-century, the Zojirushi corporation, based in Kyoto, made breakthroughs in refrigerator designs, making refrigerators cheaper and more accessible for restaurant proprietors and

4640-599: The winter in climates where the surface freezes thickly enough to support human weight. Rinks can also be made in cold climates by enclosing a level area of ground, filling it with water, and letting it freeze. Snow may be packed to use as a containment material. An example of this type of "rink", which is a body of water converted into a skating trail during winter, is the Rideau Canal Skateway in Ottawa, Ontario . In any climate, an arena ice surface can be installed in

4756-440: The "process" of refrigerant flow through an HVACR unit, whether it is a packaged or split system. Heat naturally flows from hot to cold. Work is applied to cool a living space or storage volume by pumping heat from a lower temperature heat source into a higher temperature heat sink. Insulation is used to reduce the work and energy needed to achieve and maintain a lower temperature in the cooled space. The operating principle of

4872-596: The 'smelly' ice substitute. It wasn't until thirty years later that refrigeration technology developed to the point where natural ice could finally be feasibly used in the rink. The world's first mechanically frozen ice rink was the Glaciarium , opened by John Gamgee , a British veterinarian and inventor, in a tent in a small building just off the Kings Road in Chelsea, London , on 7 January 1876. Gamgee had become fascinated by

4988-511: The 1800s marked a rise in the deliberate construction of ice rinks in numerous areas of the world. The word "rink" is a word of Scottish origin meaning "course", used to describe the ice surface used in the sport of curling , but was kept in use once the winter team sport of ice hockey became established. There are two types of ice rinks in prevalent use today: natural ice rinks , where freezing occurs from cold ambient temperatures, and artificial ice rinks (or mechanically frozen), where

5104-511: The 19th century, they began to make use of the ice trade to develop cold chains . In the late 19th through mid-20th centuries, mechanical refrigeration was developed, improved, and greatly expanded in its reach. Refrigeration has thus rapidly evolved in the past century, from ice harvesting to temperature-controlled rail cars , refrigerator trucks , and ubiquitous refrigerators and freezers in both stores and homes in many countries. The introduction of refrigerated rail cars contributed to

5220-732: The Caribbean islands as well as the southern states. In the beginning, Tudor lost thousands of dollars, but eventually turned a profit as he constructed icehouses in Charleston, Virginia and in the Cuban port town of Havana. These icehouses as well as better insulated ships helped reduce ice wastage from 66% to 8%. This efficiency gain influenced Tudor to expand his ice market to other towns with icehouses such as New Orleans and Savannah. This ice market further expanded as harvesting ice became faster and cheaper after one of Tudor's suppliers, Nathaniel Wyeth, invented

5336-626: The Jews used ice to cool beverages rather than to preserve food. Other ancient cultures such as the Greeks and the Romans dug large snow pits insulated with grass, chaff, or branches of trees as cold storage. Like the Jews, the Greeks and Romans did not use ice and snow to preserve food, but primarily as a means to cool beverages. Egyptians cooled water by evaporation in shallow earthen jars on the roofs of their houses at night. The ancient people of India used this same concept to produce ice. The Persians stored ice in

5452-655: The United Kingdom, of which only 9 had significant amounts of meat condemned. Refrigerated shipping also led to a broader meat and dairy boom in Australasia and South America. J & E Hall of Dartford , England outfitted the SS Selembria with a vapor compression system to bring 30,000 carcasses of mutton from the Falkland Islands in 1886. In the years ahead, the industry rapidly expanded to Australia, Argentina and

5568-407: The United States and a population of 127 million. Yet, while the United States population has continued to climb, citizens pursuing agriculture continue to decline. Based on the 2007 US Census, less than one percent of a population of 310 million people claim farming as an occupation today. However, the increasing population has led to an increasing demand for agricultural products, which is met through

5684-692: The United States opened in 1894, the North Avenue Ice Palace in Baltimore, Maryland , and the Ice Palace in New York City . The St. Nicholas Rink , ( a.k.a. "St. Nicholas Arena"), was an indoor ice rink in New York City which existed from 1896 until its demolition in the 1980s. It was one of the earliest American indoor ice rinks made of mechanically frozen ice in North America and gave ice skaters

5800-474: The United States. By the 1890s, refrigeration played a vital role in the distribution of food. The meat-packing industry relied heavily on natural ice in the 1880s and continued to rely on manufactured ice as those technologies became available. By 1900, the meat-packing houses of Chicago had adopted ammonia-cycle commercial refrigeration. By 1914, almost every location used artificial refrigeration. The major meat packers , Armour, Swift, and Wilson, had purchased

5916-470: The United States. As a result, United States farmers quickly became the most productive in the world, and entire new food systems arose. In order to reduce humidity levels and spoiling due to bacterial growth, refrigeration is used for meat, produce, and dairy processing in farming today. Refrigeration systems are used the heaviest in the warmer months for farming produce, which must be cooled as soon as possible in order to meet quality standards and increase

6032-525: The acceptance of the refrigerated rail cars led to an increase of car loads from 4,500 carloads in 1895 to between 8,000 and 10,000 carloads in 1905. The Gulf States, Arkansas, Missouri and Tennessee entered into strawberry production on a large-scale while Mississippi became the center of the tomato industry . New Mexico, Colorado, Arizona, and Nevada grew cantaloupes. Without refrigeration, this would have not been possible. By 1917, well-established fruit and vegetable areas that were close to eastern markets felt

6148-458: The adoption of the refrigerated rail car. After the slow adoption of the refrigerated car, the beef packing industry dominated the refrigerated rail car business with their ability to control ice plants and the setting of icing fees. The United States Department of Agriculture estimated that, in 1916, over sixty-nine percent of the cattle killed in the country was done in plants involved in interstate trade. The same companies that were also involved in

6264-489: The advent of the household refrigerator, people would have to shop on a daily basis for the supplies needed for their meals. The introduction of refrigeration allowed for the hygienic handling and storage of perishables, and as such, promoted output growth, consumption, and the availability of nutrition. The change in our method of food preservation moved us away from salts to a more manageable sodium level. The ability to move and store perishables such as meat and dairy led to

6380-500: The business was a costly failure. In 1842, John Gorrie created a system capable of refrigerating water to produce ice. Although it was a commercial failure, it inspired scientists and inventors around the world. France's Ferdinand Carre was one of the inspired and he created an ice producing system that was simpler and smaller than that of Gorrie. During the Civil War, cities such as New Orleans could no longer get ice from New England via

6496-416: The case of concrete, to keep it from being marked). This thin layer is painted white or pale blue for better contrast; markings necessary for hockey or curling are also placed, along with logos or other decorations. Another thin layer of water is sprayed on top of this. The ice is built up to a thickness of 19 to 38 mm ( 3 ⁄ 4 to 1 + 1 ⁄ 2  in). Synthetic rinks are constructed from

6612-526: The coastal ice trade. Carre's refrigeration system became the solution to New Orleans' ice problems and, by 1865, the city had three of Carre's machines. In 1867, in San Antonio, Texas, a French immigrant named Andrew Muhl built an ice-making machine to help service the expanding beef industry before moving it to Waco in 1871. In 1873, the patent for this machine was contracted by the Columbus Iron Works,

6728-586: The debate of how to compete against the American advantage of unrefrigerated beef sales to the United Kingdom . In 1873 he prepared the sailing ship Norfolk for an experimental beef shipment to the United Kingdom, which used a cold room system instead of a refrigeration system. The venture was a failure as the ice was consumed faster than expected. The first gas absorption refrigeration system using gaseous ammonia dissolved in water (referred to as "aqua ammonia")

6844-485: The development of smaller, lighter, and cheaper refrigerators. The average price of a refrigerator dropped from $ 275 to $ 154 with the synthesis of Freon. This lower price allowed ownership of refrigerators in American households to exceed 50% by 1940. Freon is a trademark of the DuPont Corporation and refers to these CFCs, and later hydro chlorofluorocarbon (HCFC) and hydro fluorocarbon (HFC), refrigerants developed in

6960-438: The east. The refrigerated car made it possible to transport perishable crops hundreds and even thousands of kilometres or miles. The most noticeable effect the car gave was a regional specialization of vegetables and fruits. The refrigeration rail car was widely used for the transportation of perishable goods up until the 1950s. By the 1960s, the nation's interstate highway system was adequately complete allowing for trucks to carry

7076-405: The eastern cities and states. In the 20th century, refrigeration has made "Galactic Cities" such as Dallas, Phoenix and Los Angeles possible. The refrigerated rail car ( refrigerated van or refrigerator car ), along with the dense railroad network, became an exceedingly important link between the marketplace and the farm allowing for a national opportunity rather than a just a regional one. Before

They conducted their experiment with the bulb of a mercury thermometer as their object and with a bellows used to quicken the evaporation; they lowered the temperature of the thermometer bulb down to −14 °C (7 °F), while the ambient temperature

7308-456: The existing farms in the United States today. This is a partial result of the market created for the frozen meat trade by the first successful shipment of frozen sheep carcasses coming from New Zealand in the 1880s. As the market continued to grow, regulations on food processing and quality began to be enforced. Eventually, electricity was introduced into rural homes in the United States, which allowed refrigeration technology to continue to expand on

7424-460: The exportation of meat. In 1882, the first successful shipment of sheep carcasses was sent from Port Chalmers in Dunedin , New Zealand, to London . By the 1890s, the frozen meat trade became increasingly more profitable in New Zealand, especially in Canterbury , where 50% of exported sheep carcasses came from in 1900. It was not long before Canterbury meat was known for the highest quality, creating

7540-507: The farm, increasing output per person. Today, refrigeration's use on the farm reduces humidity levels, avoids spoiling due to bacterial growth, and assists in preservation. The introduction of refrigeration and evolution of additional technologies drastically changed agriculture in the United States. During the beginning of the 20th century, farming was a common occupation and lifestyle for United States citizens, as most farmers actually lived on their farm. In 1935, there were 6.8 million farms in

7656-454: The feasibility and then popularity of the modern supermarket. Fruits and vegetables out of season, or grown in distant locations, are now available at relatively low prices. Refrigerators have led to a huge increase in meat and dairy products as a portion of overall supermarket sales. As well as changing the goods purchased at the market, the ability to store these foods for extended periods of time has led to an increase in leisure time. Prior to

7772-523: The first working vapor-compression refrigeration system in the world. It was a closed-cycle that could operate continuously, as he described in his patent: His prototype system worked although it did not succeed commercially. In 1842, a similar attempt was made by American physician, John Gorrie , who built a working prototype, but it was a commercial failure. Like many of the medical experts during this time, Gorrie thought too much exposure to tropical heat led to mental and physical degeneration, as well as

7888-430: The general public. Methods of refrigeration can be classified as non-cyclic , cyclic , thermoelectric and magnetic . This refrigeration method cools a contained area by melting ice, or by sublimating dry ice . Perhaps the simplest example of this is a portable cooler, where items are put in it, then ice is poured over the top. Regular ice can maintain temperatures near, but not below the freezing point, unless salt

8004-569: The heat output of the refrigeration process, and also may be designed to be reversible, but are otherwise similar to air conditioning units. Refrigeration has had a large impact on industry, lifestyle, agriculture, and settlement patterns. The idea of preserving food dates back to human prehistory , but for thousands of years humans were limited regarding the means of doing so. They used curing via salting and drying , and they made use of natural coolness in caves , root cellars , and winter weather, but other means of cooling were unavailable. In

8120-624: The highest levels of ice hockey . Historically, earlier ice rinks were smaller than today. Official National Hockey League rinks are 26 m × 61 m (85 ft × 200 ft). The dimensions originate from the size of the Victoria Skating Rink in Montreal, Quebec , Canada. Official Olympic and International ice hockey rinks have dimensions of 30 m × 60 m (98.4 ft × 197 ft). Sledge hockey ( a.k.a. "Para ice hockey", or "sled hockey"), uses

8236-571: The ice and freeze into rounded peaks. Between events, especially if the arena is being used without need for the ice surface, it is either covered with a heavily insulated floor or melted by allowing the fluid in the pipes below the ice to warm. A highly specialized form of rink is used for speed skating ; this is a large oval (or ring ) much like an athletic track. Because of their limited use, speed skating ovals are far less common than hockey or curling rinks. Those skilled at preparing arena ice are often in demand for major events where ice quality

8352-470: The increase in adult stature (in the US) through improved nutrition, and when the indirect effects associated with improvements in the quality of nutrients and the reduction in illness is additionally factored in, the overall impact becomes considerably larger. Recent studies have also shown a negative relationship between the number of refrigerators in a household and the rate of gastric cancer mortality. Probably

8468-421: The invention of the refrigerated rail car, it was impossible to ship perishable food products long distances. The beef packing industry made the first demand push for refrigeration cars. The railroad companies were slow to adopt this new invention because of their heavy investments in cattle cars, stockyards, and feedlots. Refrigeration cars were also complex and costly compared to other rail cars, which also slowed

8584-406: The lanes surround the exterior of an ice rink. The sport requires the use of a special type of racing skate, the speed skating ice skate . Refrigeration Refrigeration is any of various types of cooling of a space, substance, or system to lower and/or maintain its temperature below the ambient one (while the removed heat is ejected to a place of higher temperature). Refrigeration

8700-512: The largest artificial outdoor refrigerated sheet of ice in North America. It is a world-class facility that is primarily used for ice sports such as ice skating, ice hockey, speed skating, and bandy. The oval hosts several national and international competitions throughout the year, including the USA Cup in bandy. The first building in Canada to be electrified was the Victoria Skating Rink which opened in 1862 in Montreal , Quebec, Canada. The rink

8816-529: The late 1920s. Thaddeus Lowe , an American balloonist, held several patents on ice-making machines. His "Compression Ice Machine" would revolutionize the cold-storage industry. In 1869, he and other investors purchased an old steamship onto which they loaded one of Lowe's refrigeration units and began shipping fresh fruit from New York to the Gulf Coast area, and fresh meat from Galveston, Texas back to New York, but because of Lowe's lack of knowledge about shipping,

8932-502: The late 1920s. These refrigerants were considered — at the time — to be less harmful than the commonly-used refrigerants of the time, including methyl formate, ammonia, methyl chloride, and sulfur dioxide. The intent was to provide refrigeration equipment for home use without danger. These CFC refrigerants answered that need. In the 1970s, though, the compounds were found to be reacting with atmospheric ozone, an important protection against solar ultraviolet radiation, and their use as

9048-473: The majority of the perishable food loads and to push out the old system of the refrigerated rail cars. The widespread use of refrigeration allowed for a vast amount of new agricultural opportunities to open up in the United States. New markets emerged throughout the United States in areas that were previously uninhabited and far-removed from heavily populated areas. New agricultural opportunity presented itself in areas that were considered rural, such as states in

9164-614: The marshlands of The Fens , skating was developed early as a pastime during winter where there were plenty of natural ice surfaces. This is the origin of the Fen skating and is said to be the birthplace of bandy . The Great Britain Bandy Association has its home in the area. In Germany, the first ice skating rink opened in 1882 in Frankfurt during a patent exhibition. It covered 520 m (5,600 sq ft) and operated for two months;

9280-450: The measurements of an ice hockey rink , though may be slightly larger due to the sport having originated in Europe where the bandy field influenced the size and development of smaller ice rinks. Tracks and trails are occasionally referred to as ice rinks in spite of their differences. Ice skating tracks and ice skating trails are used for recreational exercise and sporting activities during

9396-500: The meat trade later implemented refrigerated transport to include vegetables and fruit. The meat packing companies had much of the expensive machinery, such as refrigerated cars, and cold storage facilities that allowed for them to effectively distribute all types of perishable goods. During World War I, a national refrigerator car pool was established by the United States Administration to deal with problem of idle cars and

9512-554: The midst of the Great Depression , President Franklin D. Roosevelt realized that rural areas would continue to lag behind urban areas in both poverty and production if they were not electrically wired. On May 11, 1935, the president signed an executive order called the Rural Electrification Administration , also known as REA. The agency provided loans to fund electric infrastructure in the rural areas. In just

9628-426: The most expensive units which they installed on train cars and in branch houses and storage facilities in the more remote distribution areas. By the middle of the 20th century, refrigeration units were designed for installation on trucks or lorries. Refrigerated vehicles are used to transport perishable goods, such as frozen foods, fruit and vegetables, and temperature-sensitive chemicals. Most modern refrigerators keep

9744-531: The most widely used current applications of refrigeration are for air conditioning of private homes and public buildings, and refrigerating foodstuffs in homes, restaurants and large storage warehouses. The use of refrigerators and walk-in coolers and freezers in kitchens, factories and warehouses for storing and processing fruits and vegetables has allowed adding fresh salads to the modern diet year round, and storing fish and meats safely for long periods. The optimum temperature range for perishable food storage

9860-486: The needs of grocers, farmers, and food shippers. Refrigerated railroad cars were introduced in the US in the 1840s for short-run transport of dairy products, but these used harvested ice to maintain a cool temperature. The new refrigerating technology first met with widespread industrial use as a means to freeze meat supplies for transport by sea in reefer ships from the British Dominions and other countries to

9976-565: The ones mentioned above have not been uncommon in history, but what separates these cities from the rest are that these cities are not along some natural channel of transport, or at some crossroad of two or more channels such as a trail, harbor, mountain, river, or valley. These large cities have been developed in areas that only a few hundred years ago would have been uninhabitable. Without a cost efficient way of cooling air and transporting water and food from great distances, these large cities would have never developed. The rapid growth of these cities

10092-438: The only winter activities or sports whereby ice skaters use tracks and lanes designed to include bends rather than using a simple straightway. Some ice rinks are constructed in a manner allowing for a speed skating rink to be created around its outside perimeter. Speed skating tracks or "rinks" can either be created naturally or artificially and are made either outdoors or inside indoor facilities. Tracks may be created by having

10208-493: The opportunity to enjoy an extended skating season. The rink was used for pleasure skating, ice hockey , and ice skating , and was an important rink involved in the development of the sports of ice hockey and boxing in the United States . The oldest indoor artificial ice rink still in use in the United States is Boston, Massachusetts 's, Matthews Arena (formerly Boston Arena) which was built between 1909 and 1910. The rink

10324-468: The pressure of competition from these distant specialized centers. Refrigeration was not limited to meat, fruit and vegetables but it also encompassed dairy product and dairy farms. In the early twentieth century, large cities got their dairy supply from farms as far as 640 kilometres (400 mi). Dairy products were not as easily transported over great distances like fruits and vegetables due to greater perishability. Refrigeration made production possible in

10440-502: The purity of water, from which ice was formed, began to increase in the early 1900s with the rise of germ theory. Numerous media outlets published articles connecting diseases such as typhoid fever with natural ice consumption. This caused ice harvesting to become illegal in certain areas of the country. All of these scenarios increased the demands for modern refrigeration and manufactured ice. Ice producing machines like that of Carre's and Muhl's were looked to as means of producing ice to meet

10556-436: The refrigeration system was designed by Jahre Linde, and was probably the first skating rink where ammonia was used as a refrigerant. Ten years later, a larger rink was permanently installed on the same site. Ice skating quickly became a favorite pastime and craze in several American cities around the mid 1800s spawning a construction period of several ice rinks. Two early indoor ice rinks made of mechanically frozen ice in

10672-409: The refrigeration technology he encountered during a study trip to America to look at Texas fever in cattle. In March of that same year it moved to a permanent venue at 379 Kings Road, where a rink measuring 12.2 by 7.3 metres (40 by 24 ft) was established. The rink was based on a concrete surface, with layers of earth, cow hair and timber planks. Atop these were laid oval copper pipes carrying

10788-494: The rink dimensions defined by a standard Canadian ice hockey rink . The sport of spongee , a.k.a. "sponge hockey", does not use ice skates. A skateless outdoor winter variant of ice hockey, spongee has its own rules codes and is played strictly within the Canadian city of Winnipeg as a cult sport. The sport generally uses the rink dimensions defined by a standard Canadian ice hockey rink . Rinkball rinks today typically use

10904-790: The same rink dimensions used by ice hockey rinks . Ringette utilizes most of the standard ice hockey markings used by Hockey Canada , but the ringette rink uses additional free-pass dots in each of the attacking zones and centre zone areas as well as a larger goal crease area. Two additional free-play lines (one in each attacking zone) are also required. A ringette rink is an ice rink designed for ice hockey which has been modified to enable ringette to be played. Though some ice surfaces are designed strictly for ringette, these ice rinks with exclusive lines and markings for ringette are usually created only at venues hosting major ringette competitions and events . Most ringette rinks are found in Canada and Finland . Playing area, size, lines and markings for

11020-506: The settlement of areas that were not on earlier main transport channels such as rivers, harbors, or valley trails. 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 Houston , Texas, and Las Vegas , Nevada. In most developed countries, cities are heavily dependent upon refrigeration in supermarkets in order to obtain their food for daily consumption. The increase in food sources has led to

11136-404: The shelf life. Meanwhile, dairy farms refrigerate milk year round to avoid spoiling. In the late 19th Century and into the very early 20th Century, except for staple foods (sugar, rice, and beans) that needed no refrigeration, the available foods were affected heavily by the seasons and what could be grown locally. Refrigeration has removed these limitations. Refrigeration played a large part in

11252-563: The size of the refrigerator. However, electric companies that were customers of GE did not benefit from a gas-powered unit. Thus, GE invested in developing an electric model. In 1927, GE released the Monitor Top, the first refrigerator to run on electricity. In 1930, Frigidaire, one of GE's main competitors, synthesized Freon . With the invention of synthetic refrigerants based mostly on a chlorofluorocarbon (CFC) chemical, safer refrigerators were possible for home and consumer use. Freon led to

11368-510: The slump in world wool markets that was heavily affecting New Zealand. After extensive research, he commissioned the Dunedin to be refitted with a compression refrigeration unit for meat shipment in 1881. On February 15, 1882, the Dunedin sailed for London with what was to be the first commercially successful refrigerated shipping voyage, and the foundation of the refrigerated meat industry . The Times commented "Today we have to record such

11484-572: The south and in the west. Shipments on a large scale from the south and California were both made around the same time, although natural ice was used from the Sierras in California rather than manufactured ice in the south. Refrigeration allowed for many areas to specialize in the growing of specific fruits. California specialized in several fruits, grapes, peaches, pears, plums, and apples, while Georgia became famous for specifically its peaches. In California,

11600-594: The sport of bandy . Its perimeter is used as an oval speed skating track. The facility was constructed between June and December 1993. It is the only regulation-sized bandy field in North America and serves as the home of USA Bandy and its national bandy teams. The $ 3.9 million renovation project planned for the Guidant John Rose Minnesota Oval was set to be completed before the opening of the rink's 29th season on November 18, 2022. The oval measures at 400 meters long and 200 meters wide, which makes it

11716-452: The spread of diseases such as malaria. He conceived the idea of using his refrigeration system to cool the air for comfort in homes and hospitals to prevent disease. American engineer Alexander Twining took out a British patent in 1850 for a vapour compression system that used ether. The first practical vapour-compression refrigeration system was built by James Harrison , a British journalist who had emigrated to Australia . His 1856 patent

11832-405: The standard Canadian ringette rink are similar to the average ice hockey rink in Canada with certain modifications. Early in its history, ringette was played mostly on rinks constructed for ice hockey, broomball , figure skating , and recreational skating, and was mostly played on outdoor rinks since few indoor ice rinks were available at the time. The organized format of broomball uses

11948-418: The technology did not progress. In fact, consumers that used the icebox in 1910 faced the same challenge of a moldy and stinky icebox that consumers had in the early 1800s. General Electric (GE) was one of the first companies to overcome these challenges. In 1911, GE released a household refrigeration unit that was powered by gas. The use of gas eliminated the need for an electric compressor motor and decreased

12064-561: The temperature between –40 and –20 °C, and have a maximum payload of around 24,000 kg gross weight (in Europe). Although commercial refrigeration quickly progressed, it had limitations that prevented it from moving into the household. First, most refrigerators were far too large. Some of the commercial units being used in 1910 weighed between five and two hundred tons. Second, commercial refrigerators were expensive to produce, purchase, and maintain. Lastly, these refrigerators were unsafe. It

12180-445: The west far from eastern markets, so much in fact that dairy farmers could pay transportation cost and still undersell their eastern competitors. Refrigeration and the refrigerated rail gave opportunity to areas with rich soil far from natural channel of transport such as a river, valley trail or harbors. "Edge city" was a term coined by Joel Garreau , whereas the term "galactic city" was coined by Lewis Mumford . These terms refer to

12296-511: The winter season including distance ice skating. Ice trails are created by natural bodies of water such as rivers, which freeze during winter, though some trails are created by removing snow to create skating lanes on large frozen lakes for ice skaters. Ice trails are usually used for pleasure skating, though the sport and recreational activity of Tour skating can involve ice skaters passing over ice trails and open areas created by frozen lakes. To date, speed skating and ice cross downhill are

12412-419: Was 18 °C (65 °F). They noted that soon after they passed the freezing point of water 0 °C (32 °F), a thin film of ice formed on the surface of the thermometer's bulb and that the ice mass was about a 6.4 millimetres ( 1 ⁄ 4  in) thick when they stopped the experiment upon reaching −14 °C (7 °F). Franklin wrote, "From this experiment, one may see the possibility of freezing

12528-435: Was created using natural ice . At the start of the twentieth century it had been described as "one of the finest covered rinks in the world" and was used during winter for pleasure skating, ice hockey, and skating sports. In summer months, the building was used for various other events. Many ice rinks consist of, or are found on, open bodies of water such as lakes, ponds, canals, and sometimes rivers; these can be used only in

12644-760: Was developed by Ferdinand Carré of France in 1859 and patented in 1860. Carl von Linde , an engineer specializing in steam locomotives and professor of engineering at the Technological University of Munich in Germany, began researching refrigeration in the 1860s and 1870s in response to demand from brewers for a technology that would allow year-round, large-scale production of lager ; he patented an improved method of liquefying gases in 1876. His new process made possible using gases such as ammonia , sulfur dioxide (SO 2 ) and methyl chloride (CH 3 Cl) as refrigerants and they were widely used for that purpose until

12760-537: Was for a vapour-compression system using ether, alcohol, or ammonia. He built a mechanical ice-making machine in 1851 on the banks of the Barwon River at Rocky Point in Geelong , Victoria , and his first commercial ice-making machine followed in 1854. Harrison also introduced commercial vapour-compression refrigeration to breweries and meat-packing houses, and by 1861, a dozen of his systems were in operation. He later entered

12876-403: Was influenced by refrigeration and an agricultural productivity increase, allowing more distant farms to effectively feed the population. Agriculture's role in developed countries has drastically changed in the last century due to many factors, including refrigeration. Statistics from the 2007 census gives information on the large concentration of agricultural sales coming from a small portion of

12992-530: Was later continued after the war. The idle car problem was the problem of refrigeration cars sitting pointlessly in between seasonal harvests. This meant that very expensive cars sat in rail yards for a good portion of the year while making no revenue for the car's owner. The car pool was a system where cars were distributed to areas as crops matured ensuring maximum use of the cars. Refrigerated rail cars moved eastward from vineyards, orchards, fields, and gardens in western states to satisfy Americas consuming market in

13108-468: Was not uncommon for commercial refrigerators to catch fire, explode, or leak toxic gases. Refrigeration did not become a household technology until these three challenges were overcome. During the early 1800s, consumers preserved their food by storing food and ice purchased from ice harvesters in iceboxes. In 1803, Thomas Moore patented a metal-lined butter-storage tub which became the prototype for most iceboxes. These iceboxes were used until nearly 1910 and

13224-412: Was only discovered in the past few decades that eggs needed to be refrigerated during shipment rather than waiting to be refrigerated after arrival at the grocery store. Meats, poultry and fish all must be kept in climate-controlled environments before being sold. Refrigeration also helps keep fruits and vegetables edible longer. One of the most influential uses of refrigeration was in the development of

13340-478: Was put into place as an amendment to the Meat Inspection Act of 1891. This new act focused on the quality of the meat and environment it is processed in. In the early 1930s, 90 percent of the urban population of the United States had electric power , in comparison to only 10 percent of rural homes. At the time, power companies did not feel that extending power to rural areas ( rural electrification ) would produce enough profit to make it worth their while. However, in

13456-413: Was unwholesome. When meat packing began to take off, consumers became nervous about the quality of the meat for consumption. Upton Sinclair 's 1906 novel The Jungle brought negative attention to the meat packing industry, by drawing to light unsanitary working conditions and processing of diseased animals. The book caught the attention of President Theodore Roosevelt , and the 1906 Meat Inspection Act
