A bottom freezer refrigerator is a popular appliance that many households use to keep their food fresh and cool. But have you ever wondered how it actually works?
Well, a bottom freezer refrigerator works on the principle of heat transfer. It uses a combination of mechanical and chemical processes to keep your food at the perfect temperature.
At the back of the refrigerator, you will find a compressor, which is responsible for circulating a special refrigerant fluid. This fluid is pumped through a series of coils and tubes, and as it flows, it absorbs heat from the inside of the refrigerator.
The heat is then transferred to the outside of the refrigerator, where it is released into the surrounding air. This is why you may feel warm air when standing near the back of the refrigerator.
Meanwhile, the cool air generated by the refrigerant fluid is directed downwards into the freezer compartment. The freezer compartment is separated from the refrigerator compartment by a partition, which prevents the cold air from seeping into the fresh food area.

The Role of the Compressor and Condenser
The compressor and condenser are vital components of a bottom freezer refrigerator. They work together to cool and maintain the desired temperature inside the refrigerator.
The Compressor
The compressor is essentially the heart of the refrigerator. It is a motorized pump that is responsible for compressing the refrigerant gas and increasing its pressure. When the compressor starts running, it sucks low-pressure refrigerant gas from the evaporator coil and compresses it into a high-pressure gas.
This compression process creates heat, raising the temperature of the refrigerant gas. The high-pressure gas then moves into the condenser, located at the back of the refrigerator.
The Condenser
The condenser is responsible for releasing the heat absorbed by the refrigerant gas. It is a network of coils or tubes with fins that promote heat transfer. As the high-pressure refrigerant gas enters the condenser, its temperature starts to decrease.
The condenser is usually located at the back of the refrigerator, near the compressor, to facilitate efficient cooling. Air from the surroundings is drawn in by a fan and passed over the condenser coils, cooling the refrigerant gas inside. This process causes the refrigerant to condense and transform from a gas to a liquid state.
Once the refrigerant has been cooled and condensed, it flows through a narrow tube called the capillary tube or expansion valve, where its pressure drops significantly. This drop in pressure causes the refrigerant to evaporate and absorb heat from the refrigerator’s interior, cooling it down.
The compressor then kicks in again, drawing the low-pressure refrigerant gas from the evaporator coil and repeating the cycle. This continuous cycle of compression, condensation, expansion, and evaporation helps maintain a consistent temperature inside the refrigerator, keeping your food fresh and cool.
By understanding the role of the compressor and condenser, you can appreciate how these components work together to keep your bottom freezer refrigerator running efficiently and effectively.
The Function of the Evaporator and Expansion Valve
The evaporator and expansion valve are crucial components in the functioning of a bottom freezer refrigerator. These components work together to cool the interior of the refrigerator and maintain the desired temperature.
The evaporator is located inside the refrigerator and is responsible for absorbing heat from the inside, cooling the air and reducing the temperature. It consists of a series of coils that are filled with a refrigerant, usually a gas or liquid, which undergoes a phase change from a high-pressure, high-temperature state to a low-pressure, low-temperature state.
As the warm air from the refrigerator comes into contact with the evaporator coils, the refrigerant evaporates, drawing heat from the air and cooling it down. This cooled air is then circulated back into the refrigerator, effectively lowering the temperature inside.
To regulate the flow of refrigerant and control the cooling process, the expansion valve is used. This valve is located between the condenser and the evaporator, and its primary function is to regulate the flow of refrigerant into the evaporator coils. It works by restricting the flow of the refrigerant, causing it to expand and cool down further.
When the refrigerant passes through the expansion valve, its pressure and temperature drop significantly. This drop in pressure allows the refrigerant to absorb more heat from the air inside the refrigerator, further cooling it down. As a result, the temperature inside the fridge is maintained at the desired level.
In summary, the evaporator and expansion valve work together to cool the interior of a bottom freezer refrigerator. The evaporator absorbs heat from the inside, while the expansion valve regulates the flow of refrigerant, facilitating the cooling process and maintaining the desired temperature.
How Does the Freezer Section Work
The freezer section of a bottom freezer refrigerator operates using the same principles as a standard freezer. It is located below the fresh food compartment and is used to store frozen foods at a temperature below 0 degrees Fahrenheit (-18 degrees Celsius).
Inside the freezer section, you will find shelves or drawers that are designed to hold frozen foods. These compartments are insulated to help maintain the cold temperature necessary for optimal food preservation.
The freezer section is equipped with a compressor, condenser, evaporator, and expansion valve, just like the rest of the refrigerator. When you select a temperature for the freezer, the compressor starts working to cool down the evaporator coil located inside the freezer section.
As the refrigerant flows through the evaporator coil, it absorbs heat from the freezer compartment, causing the temperature to decrease. The cold air generated by the evaporator coil is circulated throughout the freezer section by a fan, ensuring even cooling and preventing frost build-up.
Any moisture in the freezer compartment is collected by a drain and directed to a condensation pan located under the refrigerator, where it is evaporated.
The freezer section also has a door with a seal that helps keep the cold air inside and the warm air outside. This door is usually opened less frequently than the fresh food compartment door, maintaining a consistent temperature and minimizing energy consumption.
Overall, the freezer section of a bottom freezer refrigerator works to provide a separate space for long-term food storage at freezing temperatures, preserving the quality and freshness of your frozen foods.
