The compressor is typically located at the back of the freezer, near the cooling coils. It is powered by an electric motor and is designed to run continuously to maintain the desired temperature inside the freezer.
When the compressor starts, it creates a high-pressure zone where the refrigerant gas is compressed. As the gas is compressed, its temperature rises significantly. This hot, high-pressure gas then flows into the condenser coils, where it gives off heat to the surrounding environment through a process called condensation.
The compressor is also equipped with a motor overload protector to prevent overheating. If the compressor gets too hot, the overload protector will trip and interrupt the power supply to the compressor. This protects the compressor from damage and allows it to cool down before starting again.
Overall, the compressor plays a vital role in the freezing process by generating the necessary pressure and temperature changes in the refrigerant gas. Without a properly functioning compressor, the freezer will not be able to maintain its temperature and preserve the freshness of the stored food.
Condenser
The condenser is an essential part of a freezer that plays a crucial role in cooling the unit. Located on the exterior of the freezer, the condenser works to remove heat from the interior and dissipate it into the surrounding environment. This process is essential for maintaining a cold temperature inside the freezer and preventing the food from spoiling.
The main function of the condenser is to turn the refrigerant gas into a liquid state. When the compressor pressurizes the refrigerant, it becomes hot and high-pressure gas. The condenser, with its coiled tubes and fins, helps to dissipate the heat from the gas, causing it to cool down and condense into a liquid form.
In most freezers, the condenser is located at the back or bottom of the unit. It is designed in such a way that air can easily circulate around the coils, which enhances the cooling process. The condenser coils are usually made of copper or aluminum, as these materials are excellent conductors of heat.

Evaporator
The evaporator is an essential component of a freezer that is responsible for cooling down the freezer to the desired temperature. It is typically located inside the freezer and is responsible for the actual cooling process.
The evaporator consists of a series of coils that are filled with a refrigerant, typically a chemical compound such as Freon. When the freezer is turned on, the compressor pumps the refrigerant into the coils of the evaporator.
As the refrigerant flows through the evaporator coils, it undergoes a phase change from a liquid to a gas. This phase change absorbs heat from the air inside the freezer, causing the temperature to decrease.
As the heat is absorbed, the evaporator coils become cold. This cold temperature is what cools down the freezer and keeps the food inside frozen. The cold air generated by the evaporator is then circulated throughout the freezer by a fan to ensure even cooling.
During this process, the refrigerant inside the evaporator absorbs heat and vaporizes. It then travels back to the compressor, where it is compressed and heated up again, starting the cycle anew.
| Evaporator | Function |
|---|---|
| Coils filled with refrigerant | Transfer heat from the air inside the freezer |
| Phase change from liquid to gas | Absorb heat and decrease temperature |

The thermostat is an essential part of a freezer that helps regulate the temperature inside. It acts as a control mechanism, ensuring that the temperature stays within the desired range. The thermostat is usually located near the top of the freezer, where it is easily accessible.
When you set the temperature on the freezer, the thermostat measures the current temperature and compares it to the desired temperature. If the temperature is too high, the thermostat signals the compressor to start cooling the freezer. Once the temperature reaches the desired level, the thermostat signals the compressor to stop cooling.
The thermostat also helps prevent the freezer from getting too cold. If the temperature drops below the desired range, the thermostat signals the defrost heater to turn on and melt any ice that may have accumulated on the freezer walls or coils. This helps maintain the efficiency of the freezer and ensures optimal performance.
Some freezers have more advanced thermostats that offer additional features, such as temperature displays and programmable settings. These thermostats allow you to easily monitor and adjust the temperature according to your specific needs.
