How a refrigerator works? - appliance repair advice



The snow and ice, cold streams, springs, caves and cellars have long been used to refrigerate meat and fish food were kept in hot weather by salting or smoking.
500 B C Egyptians and Indians were ice cold nights by putting water in pots in the ground and keeping them moist pots.
In 18th century England, servants collected ice in winter and put in coolers, where ice sheets were packed in salt, wrapped in strips of flannel, and stored underground to keep them frozen until summer.
In the early 19th century, ice boxes were used in England.
Natural ice was harvested, distributed and used in commercial applications and at home to mid-1800s trade ice between Boston and the South was one of the first victims of the civil war.
Wooden boxes lined with tin or zinc and insulated with various materials, including cork, sawdust, and algae were used to hold the blocks of ice and food in the refrigerator drip pan collected the meltwater - and had to be emptied daily.


Pioneers in refrigeration included Dr. William Cullen, a Scotsman, whose studies in the early 1700s dealt the evaporation of liquid in a vacuum Michael Farady, a Londoner who in the early 1800s liquefied ammonia to cause cooling, and Dr. John Goorie of Apalachicola, Florida, who has built a machine to make ice to cool the air for yellow fever patients in 1834 compression refrigeration system today works on a concept tailored experiences of Farady it consists in compressing the gas in a liquid which will then absorb the heat in doing so, it returns to the gas this is a simplified description of what happens in a domestic refrigerator, freezer, air conditioner or a dehumidifier.
Mild winters in 1889 and 1890 created a serious shortage of natural ice in the US This stimulated the use of mechanical cooling for the freezing and storage of fish and brewery, dairy and packaging industries commercial refrigeration techniques meat were also applied to railway cars, were used in refrigerators in grocery stores and in various ways in manufacturing.
Two of the first refrigerators at home both appeared in Fort Wayne, Indiana, where, in 1911, General Electric unveiled a unit invented by a French monk In 1915, the first refrigerator Guardian - a predecessor to the Frigidaire - has was assembled in a wash house in a backyard Fort Wayne.
kelvinator and Servel models were among some two refrigerators dozen homes introduced to the market in 1916 U S In 1920, the number increased to more than 200 compressors were usually by straps attached to motors located in the basement or in an adjoining room.



In 1918 Kelvinator introduced the first refrigerator with any type of automatic control A 1922 manufacturer model had a wooden wardrobe, a compressor water-cooled, two ice cube trays and nine cubic feet of storage It cost 714 in 1923 Frigidaire introduced the first self unit -contained steel cabinets and porcelain began to appear in the mid 20s.
In the 1920s and 30s, consumers were introduced in freezers when the first electric refrigerators with freezer compartment came on the market mass production of modern refrigerators didn t start until after World War II.
In the 1930s Freon 12 has been used to replace sulfur dioxide as the most commonly used refrigerant.
During the 1940s, the frozen food storage has become widely used by consumers.
Refrigeration started jumping in 1950 and 60 when innovations such as automatic defrosting and automatic ice makers appeared.



The environment has become a priority in the 1970s and 80s, leading to more energy efficient refrigerators and elimination of chlorofluorocarbons in the sealed refrigeration systems.
Today, the refrigerator is the most used appliance in America, found more than 99 5 American households.
