Fridge or Refrigerator has changed our food habits, but how Refrigerator is changed since 1750s. Let's take a look.....

The history of artificial refrigeration began when professor William Cullen designed a small refrigerating machine in 1755. Cullen used a pump to create a partial vaccum over the containers of diethylamide ether, which then boiled absorbing heat from surrounding air but had no practical application at that time

In 1805, American innovator Oliver Evans described a closed vapour compression refrigeration cycle for the production of ice by ether under vaccum.

In 1820, the British scientist Michael Faraday liquidised ammonia and other gases by using high pressure and low temperature.

In 1834, an American expatriate in Great Britain, Jacob Perkins built first working vapour compression refrigeration system. It was a closed cycle device that could operate continuously

A similar attempt was made in 1842, by American Physician John Gorrie who built a working prototype, but it was a commercial failure. 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 was for a vapour compression system, using ether, alcohol and ammonia. Harrison also introduced commercial vapour- compression refrigeration to breweries and meat packing houses and by 1861, a dozen of his systems were in operation.

The first gas absortion refrigeration system using gases ammonia dissolved in water, was developed by Fredinand Carre of France in 1859 and patented in 1860

Carl Von Linde, an engineering professor of the Technology University Munich in Germany patented an improved method of liquefying gases in 1876. His new patent made possible the use of gases such as ammonia, Sulfur dioxide, methyl chloride as refrigerant and they were widely used for that purpose until the late 1920s

In 1913 refrigerators for home and domestic use was invented by Fred W. Wolf. In 1914, engineer Nathaniel B. Wales introduced an idea for a practical electric refrigeration unit, which later became the basis for the Kalvinator.

A self contained refrigerator, with a compressor on the bottom of the cabinet was invented by Alfred Mellows in 1916. Mellows produced his refrigerator commercially but was brought out by William C. Durant in 1918. In 1918, Kalvinator company introduced the first refrigerator with any type of automatic control. The absortion refrigerator was invented by Boltzar Von Platen and Carl Manters from Sweden in 19

The first refrigerator to see widespread used was the General Electric 'Monitor Top' introduced in 1927. Over a million units were produced. As the refrigerating medium, these refrigerators used either Sulfur dioxide, which is corrosive to the eyes and may cause loss of vision, painful skin burns and lesions or methyl formats, which is highly flammable and harmful to eyes

The introduction toon of Freon in the 1920s expanded the refrigerator market during the 1930s, provided a safer low toxicity alternative o perviously used refrigerators.

Separate Freezer became common during the 1940s, the popular term for the unit was deep fridge. These devices or appliances didn't go into mass production for use in the in the home until after World War II

The 1950s and 1960s saw technical advances like automatic deforesting and automatic ice making. More efficient refrigerators were developed in 1970s and 1980s, even through environmental issues led the banning of very effective (Feron) refrigerators.
In early 1950s, most refrigerators were white, but from mid 1950s through present day designers and manufacturers put colours onto refrigerators. In the late 1950s and early 1960s pastel colours became popular. In the late 1960s and throughout 1970s, earth stone colours were popular including Harvest Gold, Avocado green and Almond. In 1980s Blakeley became fashionable. In late 1990s stainless steel came into vogue. In 2009 one manufacturer introduce multiple designs.
