How does a Refrigerator work?

A refrigerator is a household appliance that keeps food and drinks at a certain temperature and prevents it from getting warmer.

The refrigerator has many parts: the compressor, condenser, evaporator, expansion valve, and fans.

Condenser – The water vapor turns into liquid water as it travels through the huge coils of tubing on the outside of your fridge.

As heat escapes from inside the fridge to make room for all the cold air, the refrigerant cools down and goes back to a liquid state.

Evaporator – Then this cooled liquid flows into a narrow tube called an ‘evaporator’ where it lets out its coldness in the form of super-cold gas that’s even colder than ice or snow!

This cold gas is drawn into the compressor and the whole process starts over again.

Compressor – This motor-driven pump forces out this cold gas, squeezing it so it becomes even colder, and pumps it back through the condenser coils where the process starts all over again.

The heat from inside your fridge warms up this gaseous refrigerant going through the evaporator, turning it back into a liquid that’s drawn into a different part of your fridge by a fan called a ‘condenser fan’.

Expansion Valve – As the hot refrigerant enters this valve, a small amount of fluid flows around it to keep everything running smoothly.

Then as more cold air blows past these blades they “chill” and blow cold air into the fridge.

Fans – The cold air is blown straight into your fridge and a warmer breeze comes out of a vent in the rear of the appliance, which warms up the kitchen so you don’t have to!

If there’s any warm air in your freezer it will be blown away by this fan too.

COMPONENTS:

Condenser Coil – This is where most of the cooling process takes place.

The liquid refrigerant travels from its source (the compressor) through tubes outside the refrigerator cabinet and becomes a gas that cools down into a liquid again.

That’s why they’re called ‘condenser coils’.

If they were on inside your fridge, they would make everything very damp because water would condense on them.

Evaporator Coil – This is a narrow tube in your fridge where the cold gas from the compressor turns back into a super-cold liquid so it can flow back to be compressed again and go through the process all over again.

Compressor – The heart of a refrigerator, this motor-driven pump forces out the coolant in a gaseous state then squeeze it until it becomes even colder before re-entering your fridge as an even colder liquid that begins its journey all over again.

If there’s any warm air in your freezer it will be blown away by this fan too.

Has been working for 50 years!

In fact, they’re designed to run 24/7 for 10 or more years.

It is powerful enough to keep all your food cold for hours without having to run constantly as an air conditioner does!

So you don’t need to worry about leaving it on while you’re out of the house for a few hours.

The evaporator coil is a narrow tube in your fridge where the cold gas from the compressor turns back into a super-cold liquid so it can flow back to be compressed again and go through the process all over again.
