How Refrigerators Work?

Engineers or other practical approach lovers out there thinking about the basics of how refrigerators work? Read our brief guide below so you acquaint yourself with the basic know how of these indigenous systems.

A refrigerator simply keeps your food fresh by keeping it at a low temperature than the one it is getting outside. This reduces the rate of harmful bacteria growing inside.

  • A refrigerator consists of several main electrical and mechanical components, including a compressor, a condenser, a thermostat for setting up the temperature and a tube for pressure adjustments.
  • Out of these the most important system is the compressor which ensures the circulation of the coolant through the system and also maintains pressure on the lower part of fridge.

Refrigerators work simply, by forcing the coolant chemical moving inside to change its state to gas from liquid. This is the cooling process which causes evaporation around the ambiance.

However, to ensure this process of coolant the pressure is adjusted to a certain number by the tube of the fridge which pushes the excess pressure outside. Doing such the excess pressure is released and the overall pressure is reduced as the state changes from liquid to gas.

Still there is more to the story to keep the fridge in operation the state needs to reverse as well in liquid sate.

  • To make this happen, the gas is again crushed to increased temperature. This all now happens through the compressor which is one of the cores of the refrigerator.
  • After the compressor has completed its task the new hot pressure gas needs cooling down which is achieved by the condenser which we discussed above.
  • The same process happens to cool this new pressure with the heat being given outside the metal pipes.
  • After this stage the coolant gas has now successfully changed state to liquid.
  • This liquid then goes back to the evaporator block where all the previous steps start again from scratch.
