How a Refrigerator Works: Compressor, Condenser and Evaporator

The person who invented the refrigerator was a genius. Its core component is the

compressor. When the fridge turns on,

the compressor squeezes the refrigerant gas, heating it up to about 90

degrees Celsius.

This hot, high-pressure gas is then sent to the condenser coils on the back of

the fridge. As it flows through these coils, it releases heat into the air,

cools down to around 45 degrees Celsius, and turns into a liquid.

Next, the liquid refrigerant enters a long, ultra-thin capillary tube.

Here, the pressure suddenly drops,

and the temperature plunges to about minus 16 degrees Celsius. After that,

the refrigerant passes through a filter and enters the evaporator coils inside

the fridge.

This is where it absorbs heat from the food,

rapidly cooling the interior while the liquid fully evaporates back into a gas.

Finally, the gas returns to the compressor, and the entire process repeats.
