However, most modern refrigerators come with built-in temperature control mechanisms to ensure that the desired temperature is maintained consistently.

Refrigerators work by removing heat from the inside of the appliance, which in turn cools the air and food stored inside. This process is achieved using a compressor, condenser, evaporator, and refrigerant. The compressor circulates the refrigerant, transferring heat from the inside to the outside of the fridge freezer. As a result, the temperature inside the appliance drops, keeping your food fresh and safe to consume.

In conclusion, fridge freezers are capable of maintaining a temperature range between 0 to 4 degrees Celsius in the refrigerator compartment and -15 to -18 degrees Celsius in the freezer compartment. Thanks to these appliances, we can safely store our perishable items and ensure that they remain fresh for an extended period of time.

Understanding the Refrigeration Process

Refrigeration is the process of removing heat from an enclosed space in order to lower its temperature. This process allows us to preserve perishable items, such as food and medicine, by keeping them cold.

To understand how a fridge freezer gets cold, it is important to know the basic principles behind the refrigeration process. The process involves a closed system containing a refrigerant, which is a substance that has a low boiling point and easily changes from a gas to a liquid and vice versa.


The refrigeration process begins with the refrigerant being evaporated by a compressor. As the refrigerant evaporates, it absorbs heat from the surrounding environment, causing the temperature to drop. This is the cooling effect we feel inside the fridge freezer.

At this stage, the evaporated refrigerant is in a gaseous state and enters the compressor, where its pressure and temperature are increased. This high-pressure, high-temperature gas is then directed to the condenser.


In the condenser, the heated refrigerant gas is cooled down, causing it to release heat to the surrounding environment. This heat exchange process allows the refrigerant to change from a gas to a liquid state.

Once the refrigerant has condensed into a liquid, it passes through an expansion valve, where its pressure is reduced. This pressure drop causes the refrigerant to expand and evaporate, starting the cycle again.

This continuous cycle of evaporation and condensation is what enables the fridge freezer to maintain a cold temperature. The refrigeration system continually removes heat from the inside of the fridge, keeping the contents cool and preventing spoilage.

It’s important to note that the refrigeration process requires energy to operate. The compressor is responsible for compressing the refrigerant gas, and this process requires electricity to run. Therefore, a fridge freezer needs to be plugged into an electrical outlet in order to operate.

In conclusion, the refrigeration process is a vital component of our daily lives, allowing us to keep perishable items cold and preventing food waste. Understanding how it works helps us appreciate the role it plays in our modern lifestyle.
