We all rely on your refrigerators to keep our drinks cold and our food fresh, but do we actually take it for granted? Since it’s just expected that something we put in our fridge will stay chilled, it’s only once a problem arises that we actually take a look into the ins and outs of the cooling process.
A refrigerator is made up of five different components: A fluid refrigerant, a compressor, condenser coils, evaporator coils and an expansion device. Let’s dive a little deeper to find out how all of these work together to make up your favorite and most used home appliance.

Refrigerators are a modern luxury – they work around the clock to
keep our food fresh and our beverages refreshing. Even though we use
ours several times each day, the refrigerator is as under-appreciated
as it gets. If you are interested in learning more about the science
of household refrigeration, Speedy Subzero has put together this
short guide explaining how refrigerators work, with some help from
Before you learn about how your refrigerator works, it is necessary
to understand two scientific principles:
Gas cools down as it expands.
When two surfaces of different temperatures come in contact, the
warmer surface cools down and the cooler surface warms up.
Knowing these two points, we can now illustrate how the household
refrigerator keeps your food cold.
The refrigerant inside your refrigerator’s tubes, currently in a
gaseous state, passes through the compressor. This causes its
temperature to rise.
The refrigerant moves through internal pipes and loses some of its
heat through exhaust fins in the back of the unit.
The refrigerant reaches the condenser where its temperature is
reduced and it turns into a liquid.
The liquid refrigerant flows through the expansion valve, causing
some of the liquid to evaporate and expand, further lowering the
As the refrigerant continues to make its way through your
refrigerator, it absorbs the heat from your food (remember principle
#2) and turns back into a gas.
The gas is sucked back in to the compressor where the cycle starts
