How a refrigeration repair system works
 |
| refrigeration system |
In a refrigerator, the liquid is forced to
evaporate so that it takes to
heat the interior of the fridge.
To understand how a refrigerator works and then learn how to fix Frigidaire parts, you have to see how the human body: it is generally the same: when we sweat, sweat produces a cold sensation by evaporation, because it takes calories on our skin.
All homes have a refrigerator. This equipment helps to keep all our food some days to several weeks. But how is it for use ensures continuous operation, for this you need to understand how things that going on in your fridge, something that makes you able to do your refrigeration repair tips.

Refrigerator repair operation:
The fluid flows in the evaporator. As it is a very fine tube, it passes dropper: molecules and disperse the fluid converted into gaseous state.
Very cold (-104 degree Fahrenheit) after he tries to warm up by absorbing heat that is inside the refrigerator.
Then, the gas is again compressed and liquefied in the condenser (outside coil), where it releases the stored heat.
You must know that the refrigerator "factory"
not cold, but
traps heat inside the fridge. If we open too
often the refrigerator door or
you put hot food, the unit turns on more often
to restore the original balance. It therefore consumes
more energy. It is also important to defrost the fridge regularly: a layer of 2 mm of ice increases fuel
consumption by 10%, as it prevents heat transfer.
Refrigerants fluid:
A refrigerant fluid quality must have several conditions. It must
evaporate at a pressure above
atmospheric pressure and at a temperature
below 32 degree Fahrenheit. It should also be chemically stable, non-toxic, and not flammable.
Many refrigerants have been used since the beginning of the innovation refrigerators. William Cullen
since the 18th century
successful in produce ice with ether, which
evaporates 25 times faster than
water. Ether is
highly flammable; the German
engineer Carl von Linde patented
in 1876 cold ammonia.
This gas is perfect, because it takes very little energy to lower the sensible heat (that exchanged with the environment without phase change). And Just 130 joules for passing a gaseous ammonia
gram 77 degree
Fahrenheit - 91.4 degree Fahrenheit.
But ammonia is highly
toxic; it is removed from the refrigerator in the 1930s.
He was then replaced by Freon, a gas family of CFCs (chlorofluorocarbons). But we see that gas causes a deterioration of the ozone layer. In 1987, 180 countries signed the Montreal Protocol, banning its use. It has since been replaced by oil, safe for the ozone layer, but Powerful greenhouse gas.
