00:00Refrigerators are essential for preserving food by keeping it cool to prevent bacterial growth.

00:05They operate by maintaining an internal temperature between 0 and 5 degrees Celsius,

00:10while freezers are much colder, between minus 18 and minus 22 degrees Celsius.

00:17A refrigerator works as a heat pump, removing heat from inside and releasing it outside.

00:23This involves several key components.

00:25Refrigerant, evaporator coils, condenser coils, and a compressor.

00:31The refrigerant, a liquid with a low boiling point, flows through pipes inside, evaporator coils,

00:37and outside, condenser coils, the refrigerator.

00:40The compressor circulates the refrigerant through the system.

00:43Inside the freezer, the refrigerant absorbs heat from the air and evaporates into a gas.

00:48The warm air rises, cools as it exchanges heat with the refrigerant, and is then circulated by a fan.

00:55The gas refrigerant is compressed into a high-pressure, high-temperature gas by the compressor.

01:00It then flows into the condenser coils, where it releases heat to the surroundings and condenses back into a liquid.

01:07The refrigerant's pressure drops through an expansion valve,

01:11cooling it down before it re-enters the evaporator coils to absorb heat again.

01:16This cycle of evaporation, compression, condensation, and expansion

01:21continuously cools the refrigerator's interior, preserving food effectively.
