Refrigerators have become an essential appliance owned by millions of households around the world. Have you ever wondered how refrigerator works and what’s behind its cooling power? Don’t think about it too much because this article will give answers to your questions! Be sure to read until the end to know how refrigerator works.
Function of Your Fridge
Owning a refrigerator has become a must. A fridge is everyone’s best friend in food preservation. It cools down food at a certain level of temperature and slows down disease-causing bacteria’s growth rate. In that way, you won’t have to go to the grocery every day to buy fresh foods because your fridge can store your foods that last for a couple of days.
But how does a fridge work? What is behind its cooling function? The next part will discuss how refrigerator works as well as the parts responsible for its function.
The scientific principles that enable your fridge to do its cooling function are condensation and evaporation. This idea was made possible by past scientists and pioneers of technology. How refrigerator works depends on its components.
Here is a list of every refrigerator’s main components:
- Condenser – A condenser is always located at the back of the refrigerator. It has a huge role in how refrigerator works. It releases off the heat that is absorbed from the inside of your fridge.
- Compressor – Your fridge has a functioning heart, too! The compressor is responsible for the pumping of air into a tube and circulating the refrigerant throughout the system.
- Evaporator – This serves as the heat-absorber on the inside of your fridge; thus, making the inside drop in temperature.
- Thermostat – This device regulates the cooling process of your fridge.
Below is the whole refrigeration process/cycle:
- Your fridge has a built-in sensor that tracks the temperature inside. When the temperature is higher than the setpoint, the sensor automatically triggers the compressor to start the cooling process.
- A liquid refrigerant will then be released. It will undergo pressurization and condensation until the temperature will rise. And from liquid, it will turn into a gas state.
- The compressor will circulate the hot gas to the back of the fridge until it reaches down to the condenser. The condenser will then convert the hot gas to its liquid form. The liquid will travel to the evaporator and along every coil inside the fridge, as well as reaching the freezer box.
- As the cycle continues, the refrigerant will absorb the hot air from the refrigerator’s interior and turn the temperature down to a cool level.
- Lastly, the refrigerant will travel back to the compressor in a gas state. This cycle continues as long as your refrigerator is turned on.
The whole refrigeration process is a product of creativity, intelligence, passion, and dedication. Thanks to those with innovative minds, our world has benefited from this great and bright invention.
