How The Refrigerator Cools Your Food
Before the advent of the refrigerator, there were various crude means of storing foodstuff.
It was through drying, salting and many other means but the refrigerator had made all that a thing of the past.
Refrigerators have been an amazing invention making living easier for mankind.
Have you ever wondered how a refrigerator cools your foodstuff and drinks?
Have you made a research about the mechanism of a refrigerator but still don’t understand?
Well, in this article, we identify the components of the refrigerating unit, how it cools substances, and the basic maintenance of the system.
Components Of The Refrigerator
It contains four different equipment namely compressor, evaporator and it also has refrigerant or working fluid/medium.
This fluid continuously circulates through all these four different equipment.
This is to enable heat transfer and thus cooling.
The refrigerant while passing through different parts, changes phase, and this enables cooling in a domestic refrigerator.
Working Principle Of A Refrigerator
A fridge can be like a heat pump.
It takes air inside the fridge and cools it by eliminating heat from it.
This heat needs to head off to someplace however and is generally extinguished at the rear of the fridge by a little fan.
On the off chance that you feel the rear of a fridge outwardly, it will ordinarily be warm if the unit is running.
Thus when a fridge is running it is truly heating the room.
Sonce we cannot make a fridge to be completely effective, the second law of thermodynamics ensures this a portion of the electrical energy gets changed over to heat.
Since in such a case that more heat gets unloaded outside the fridge than gets pumped out.
So regardless of whether you open the fridge to allow the cool air to get away from the fridge, it will in any case be heating the room more than cooling it.
Basic Maintenance Of A Refrigerator
Clean the Condenser Coils
Dusty condenser coils cause a refrigerator to work harder.
This translates into more significant energy bills and a shorter life expectancy for the fridge.
To prevent this from happening, use a vacuum or broom to remove dust build-up from the coils every three months
Remove Deposits From Drain Hole
Most refrigerators rely on a drain hole to remove condensation.
Remove any food particles and mineral deposits from the drain hole according to the instructions in your owner’s manual.
Check and Wipe the Gaskets
The gaskets on the refrigerator and freezer doors seal the cold air in and keep the warm air out, which is vital to the efficiency of your fridge.
So, it’s essential to make sure that the seal is as tight as it should be.
Change the Water Filter
Does your refrigerator have an ice maker or a water dispenser?
If so, it probably also has a water filter that needs to be changed regularly.
Replace your filter every six months or as recommended by the owner’s manual.
Conclusion
We have covered all you need to know about the working of refrigerators and the basic maintenance of the refrigerating system to lengthen their lifespan.
