How does a fridge freezer work?
A fridge freezer is a common household appliance that is used to store and preserve food at a low temperature. It works on the principle of removing heat from the inside of the unit and releasing it to the surrounding environment. This process is facilitated by a refrigeration system consisting of several key components.
1. Compressor
The compressor is the heart of the fridge freezer and is responsible for circulating the refrigerant throughout the system. It compresses the low-pressure refrigerant gas, raising its temperature and pressure.
2. Condenser
After leaving the compressor, the high-pressure refrigerant flows into the condenser. Here, it releases heat to the surrounding air or water, causing it to condense into a high-pressure liquid.
3. Expansion Valve
Once the refrigerant has been condensed, it flows through the expansion valve, which controls the flow and reduces its pressure. This causes the refrigerant to rapidly expand and cool down.
4. Evaporator
The cooled refrigerant then enters the evaporator, where it absorbs heat from the inside of the fridge freezer. This heat transfer process cools the air inside and maintains a low temperature, preserving the food stored inside.
Overall, the fridge freezer works by continually circulating the refrigerant through these four components, creating a cycle that removes heat from the inside and keeps the contents cool.
