Deep Freezer 200 Litre

[Billie Kjergaard]

Anupright freezer will have a smaller footprint and fit nicely between kitchen cabinets. Common upright freezer sizes include compact, small, medium and large. As cubic footage increases, the freezer will typically be taller rather than wider or deeper. The built-in, vertical shelving and door storage make it easy to organize and the finish options allow you to match other appliances.

Inside, chest freezers generally have more open, usable space overall but may lack some of the shelving and storage compartments of an upright freezer, often making them less convenient to organize. Food stored toward the bottom of the freezer can be more difficult to reach as well.

There is a wide range of sizes to choose from for both upright and Maytag chest freezers. In terms of storage space, expect anywhere from 3 to 25 cubic feet for either type of freezer. As a general rule of thumb, each cubic foot can hold approximately 25 lbs of food. When it comes to exterior dimensions, these two freezer types have completely different shapes, so they will take up space in different ways.

To help determine the best freezer size for your family, you could allow for 2.5 cubic feet of freezer space for each household member. For a family of four, a freezer with around 10 to 16 cubic feet of capacity could be ideal, depending on your storage needs. Larger items will require more space, so factor food size into your decision as well.

To store up to 350 lbs of food, a 14 cubic foot freezer may fit your needs. Although weight and volume are not the same, you can estimate that 1 cubic foot of freezer space may hold approximately 25 lbs. Medium freezers are usually 10 to 16 cubic feet and could hold up to around 400 lbs of food.

The first cooling systems for food involved ice.[6] Artificial refrigeration began in the mid-1750s, and developed in the early 1800s.[7] In 1834, the first working vapor-compression refrigeration, using the same technology seen in air conditioners, system was built.[8] The first commercial ice-making machine was invented in 1854.[9] In 1913, refrigerators for home use were invented.[10] In 1923 Frigidaire introduced the first self-contained unit. The introduction of Freon in the 1920s expanded the refrigerator market during the 1930s. Home freezers as separate compartments (larger than necessary just for ice cubes) were introduced in 1940. Frozen foods, previously a luxury item, became commonplace.

Domestic refrigerators and freezers for food storage are made in a range of sizes. Among the smallest are Peltier-type refrigerators designed to chill beverages. A large domestic refrigerator stands as tall as a person and may be about one metre (3 ft 3 in) wide with a capacity of 0.6 m3 (21 cu ft). Refrigerators and freezers may be free standing, or built into a kitchen. The refrigerator allows the modern household to keep food fresh for longer than before. Freezers allow people to buy perishable food in bulk and eat it at leisure, and make bulk purchases.

Ancient Iranians were among the first to invent a form of cooler utilizing the principles of evaporative cooling and radiative cooling called yakhchāls. These complexes used subterranean storage spaces, a large thickly insulated above-ground domed structure, and outfitted with badgirs (wind-catchers) and series of qanats (aqueducts).[citation needed][11]

In modern times, before the invention of the modern electric refrigerator, icehouses and iceboxes were used to provide cool storage for most of the year. Placed near freshwater lakes or packed with snow and ice during the winter, they were once very common. Natural means are still used to cool foods today. On mountainsides, runoff from melting snow is a convenient way to cool drinks, and during the winter one can keep milk fresh much longer just by keeping it outdoors. The word "refrigeratory" was used at least as early as the 17th century.[12]

The history of artificial refrigeration began when Scottish professor William Cullen designed a small refrigerating machine in 1755. Cullen used a pump to create a partial vacuum over a container of diethyl ether, which then boiled, absorbing heat from the surrounding air.[13] The experiment even created a small amount of ice, but had no practical application at that time.

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 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. It was a closed-cycle device that could operate continuously.[14] A similar attempt was made in 1842, by American physician, John Gorrie,[15] who built a working prototype, but it was a commercial failure. American engineer Alexander Twining took out a British patent in 1850 for a vapor compression system that used ether.

The first practical vapor compression refrigeration system was built by James Harrison, a Scottish Australian. His 1856 patent was for a vapor 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 vapor-compression refrigeration to breweries and meat packing houses, and by 1861, a dozen of his systems were in operation.

The first gas absorption refrigeration system (compressor-less and powered by a heat-source) was developed by Edward Toussaint of France in 1859 and patented in 1860. It used gaseous ammonia dissolved in water ("aqua ammonia").

Carl von Linde, an engineering professor at the Technological University Munich in Germany, patented an improved method of liquefying gases in 1876, creating the first reliable and efficient compressed-ammonia refrigerator.[16] His new process made possible the use of gases such as ammonia (NH3), sulfur dioxide (SO2) and methyl chloride (CH3Cl) as refrigerants, which were widely used for that purpose until the late 1920s despite safety concerns.[17] In 1895 he discovered the refrigeration cycle.

In 1894, Hungarian inventor and industrialist Istvn Rck started to manufacture a large industrial ammonia refrigerator which was powered by electric compressors (together with the Esslingen Machine Works). Its electric compressors were manufactured by the Ganz Works. At the 1896 Millennium Exhibition, Rck and the Esslingen Machine Works presented a 6-tonne capacity artificial ice producing plant. In 1906, the first large Hungarian cold store (with a capacity of 3,000 tonnes, the largest in Europe) opened in Tth Klmn Street, Budapest, the machine was manufactured by the Ganz Works. Until nationalisation after the Second World War, large-scale industrial refrigerator production in Hungary was in the hands of Rck and Ganz Works.[18]

Commercial refrigerator and freezer units, which go by many other names, were in use for almost 40 years prior to the common home models. They used gas systems such as ammonia (R-717) or sulfur dioxide (R-764), which occasionally leaked, making them unsafe for home use. Practical household refrigerators were introduced in 1915 and gained wider acceptance in the United States in the 1930s as prices fell and non-toxic, non-flammable synthetic refrigerants such as Freon-12 (R-12) were introduced. However, R-12 proved to be damaging to the ozone layer, causing governments to issue a ban on its use in new refrigerators and air-conditioning systems in 1994. The less harmful replacement for R-12, R-134a (tetrafluoroethane), has been in common use since 1990, but R-12 is still found in many old systems.

The glass-fronted beverage cooler is mostly used as a commercial refrigerator. These types of appliances are usually designed for specific load requirements, resulting in a larger cooling mechanism. This ensures that they are able to cope with a large throughput of drinks and frequent door opening. As a result, it is common for these types of commercial refrigerators to compose up to 50% of the energy usage of a supermarket.[19]
