 Learn Some Details About Refrigerator Repair

In this article, you’ll learn how a refrigerator works, its features, properties, advantages and disadvantages.

1. This device is the most used appliance in the world, because it helps keep food cool and in good condition for a long time. Since it was invented, has evolved into the inner workings, innovation in design and cooling technology is increasingly eficiente.

2. A refrigerator is a heat engine that allows heat transfer with an energy cost of at medio.Objeto Technology

3. Karl von Linde (Berndorf , 1842 , Munich , 1934) was a German Inventor. His most important works were related to achieving very low temperatures and the liquefaction of air. He obtained pure liquid oxygen and designed and built the first chiller cooler compresión.

4. The coolers we see daily are made by a machine (refrigerator) that transfers heat from inside a container adiabatic walls to the environment.

The methods used to achieve this heat transfer are varied and in this paper we refer specifically absorption method by a solution of ammonia-water

If we do not extract this heat the water temperature increase can not occur until more absorption and then cease all ammonia evaporation must therefore cool the absorber A during the absorption process. This can be done by directing a stream of air into the container when all the ammonia have evaporated liquid from the container B, the water in the container A will be loaded with the original contents of ammonia. Then the system is able to repeat the process.

6. Characteristics can have a single compartment, which can be refrigerated or frozen, or you can have both. Refrigerators with two compartments were introduced to the public by General Electric in 1939. Some refrigerators are divided into four zones to store different types of food: **** -30 ° C or -22 ° F ( freezer, to freeze ) *** -20 ° C or -4 º F ( (freezer , hold) * * 0 ° C or 32 ° F refrigerator (meat ) • 4 ° C or 40 ° F (refrigerator) 10 ° C or 50 ° F (and other miscellaneous vegetables ) the capacity of the refrigerator is usually measured in liters. possibilities newer refrigerators have expanded significantly ; may have: An LCD suggesting what types of food should be stored at what temperatures and the expiration date of the stored products. Indicator filter conditions suggesting when it’s time to change.

7. A power failure warning, alerting the user about the blackout, usually by flashing the screen showing the temperature. You can display the maximum temperature reached during the blackout , along with information on whether the frozen food thawed or can bring harmful bacteria. ? The recycling of old refrigerators has been an ecological concern, originally by the freezing of Freon that damaged the atmosphere in case of leakage, but later by the destruction of CFC insulation . Modern refrigerators use a refrigerant called HFC-134a 1,2,2,2 -tetrafluoroethane ) in place of Freon that damages the ozone. ( Vegetables and other produce several )

Cooler Properties

The ammonia absorption refrigerator is especially attractive when heat has a low temperature 100 to 200 degrees Celsius, since this system requires a very small amount of labor in comparison with other cooling systems, and the efficiency of this system is relatively high at around 18% , which can be improved by adding some auxiliary devices such as scanners or bubble columns , rectifiers or arrangements for reflux, heat exchangers, pre-coolers of liquid, etc… reaching up to 70 % . ? facilities used refrigerants ammonia have found a powerful opponent reaching toxicity in high concentrations in the air and therefore the latent danger of leakage that endangers workers and residents in the vicinity of the installation.

The ammonia absorption system allows for lower temperatures than those obtained with other systems (below zero) as the absorption of lithium bromide and water, which has been widely used for air conditioners.

Conclusion

Through this work we learned that the refrigerator is very necessary for everyday life, and to keep our food fresh.
