What is mechanical control and how does it work in a refrigerator?

1. 1. Mechanical control is a cooling process that relies on a mechanical compressor, condenser, refrigerants, and evaporators.
   2. It works by absorbing or diverting heat away from the refrigerator’s interior.
   3. Whereas a digital inverter compressor adjusts energy consumption by increasing or decreasing the revolutions per minute (RPM), the mechanical compressor is consistent.
   4. The mechanical compressor compresses the refrigerant (mostly propane) to a higher pressure, resulting in a higher temperature as well.
   5. It then proceeds to the condenser where it loses the heat and cools into liquid.
   6. A subsequent reduction of pressure causes the evaporation of a part of the liquid.
   7. The cool air is passed through vents to cool the interior of the fridge.
   8. Cooling happens because the vapor is colder than the temperature of the enclosed space to be refrigerated.
   9. This process is known as the vaporization cycle and it happens continuously, regulated by a thermostat inside the fridge.
