Freezer Vs Refrigerator is an appliance that helps to keep food fresh. A freezer typically has a lower temperature than a refrigerator, which can impact the food quality because it slows down bacteria growth rates.
The main difference between these two is how long your food will last: with a freezer, you look at about six months or less before meat starts to go wrong.
What Is A Refrigerator?
A refrigerator or a fridge is a cooling apparatus with various applications. It consists of an insulated compartment and a heat pump. A freezer maintains higher temperatures than a refrigerator.
Refrigerator comes from the Latin “refrigerate,” which means to cool down. The first refrigerators were invented in 1834 by Jacob Perkins.
A refrigerator usually stores foodstuffs and other items that must be preserved at a cold temperature. It contains the compartment in which frozen food can be stored.
The compartment will maintain a low temperature (-18 °C) for safe operation at average room temperatures. The cooling elements are placed behind the coils to allow air to flow freely.
In rising temperatures, fans are also installed to blow cold air into the compartment. Cold air flows out and is taken from a freezer via doors or drawers.
Pros:
- Keeps food fresh for longer periods
- Provides ample storage space for food and drinks
- Helps to reduce food waste
- Saves time and effort with frost-free technology
- Energy-efficient models can save on electricity bills
Cons:
- It can be noisy when the compressor kicks in
- Large sizes can take up valuable kitchen space
- Repairs can be expensive
- Some models may have limited storage space
- Smart features can be costly and may not always work as intended.
What Is Freezer?
A freezer is a cooling device that maintains lower temperatures than refrigerators with compartments. At temperatures, the water in food is frozen and stops bacteria from growing or multiplying.
Alfred Bird invented the first freezer in 1892.
The freezer maintains a cold temperature because it has a refrigerant that turns from liquid to gas when moving through the freezer ducts. This process absorbs heat energy and later releases it as more excellent gas.
The compartment maintains low temperatures because it contains insulating foam, cork, and rubber materials. These materials are placed between freezer walls so that it does not conduct heat from outside.
In addition, doors also contain air gaps to prevent warm air from entering inside.
Pros:
- Freezers allow you to buy food in bulk, saving you money in the long run.
- You can freeze leftovers and meals, reducing waste and making it easier to meal prep.
- A freezer can help you stock seasonal items, such as fruits and vegetables, throughout the year.
Cons:
- Freezers require a lot of electricity to run and can drive up your energy bill.
- They take up much space, so you’ll need enough room to accommodate one.
- Chest freezers can be difficult to organize and access items at the bottom without rearranging the entire freezer.
Difference Between Freezer and Refrigerator
Working principle
The freezer uses a refrigerant to turn from liquid to gas while the freezer maintains low temperatures because of insulating materials. Meanwhile, the refrigerator uses an electric motor as its power source.
The compartment contains frozen food, while the freezer is the whole unit that holds refrigerated food.
Temperature
The compartment maintains lower temperatures. The compartment has a temperature usually between -18 to -25 °C, during the freezer range from 0 to 5 degrees Celsius.
The refrigerator maintains average room temperature, and the freezer stores frozen food. Shapes and sizes
In terms of shape, a refrigerator can be built-in or free-standing. The freezer also comes in different forms, including chest, upright, built into kitchen cabinets.
In terms of size, a freezer has a larger capacity than a refrigerator. It can store food for a long time compared to refrigerators. It is usually at least four times larger than a refrigerator.
Application
A refrigerator is used for storing perishable foodstuffs. It is essential that the fridge maintains a stable temperature and have compartments in case frozen food is needed. A refrigerator is also known as a domestic refrigerator or kitchen refrigerator today.
The refrigerator stores drinks and perishable foods such as meat, fish, poultry, etc. They can be placed in different areas inside the compartment. However, frozen food can be stored separately from drinks or other food items.

Common Mistakes For Storing Food
1. Not maintaining enough temperature – It should maintain a constant and low temperature. This is important to keep the nutrients and flavors of foods when freezing or preserving them.
2. Storing large – It should not be filled to the top. A space of about 1/3 of a freezer is needed. Otherwise, the freezer runs longer and might use more energy than necessary.
3. Storing food that can spoil quickly – Foodstuffs such as meat, seafood, and poultry must be stored separately from vegetables and fruit. Otherwise, it will be contaminated by bacteria from beef.
4. Leaving the freezer door open – It should not empty the freezer for long. It is essential to allow the compartment to maintain a low temperature and avoid heat leakage outside.
5. Not defrosting – If the freezer compartment is frozen, it needs to be defrosted using the freezer’s automatic defrost system. If the freezer is not fully defrosted, it can cause freezer burn, and food might not taste good after thawing.
6. Not cleaning – It is essential to clean the compartment every six months because of moisture build-up, which will cause the freezer to burn quickly. Food will lose its flavor after burn.
FAQs
Can a freezer be used as a refrigerator?
A freezer can never be used as a refrigerator because freezing does not maintain food at optimum temperatures.
Yes, frozen foods must be placed inside the compartment, but only this should be done in the freezer. It will never keep food at room temperature, even if the freezer is open and exposed to air.
Is a deep freezer colder than a refrigerator?
Yes. The compartment has a temperature between -18 to -25 °C, while the freezer has an average of 0 to 5 °C.
A deep compartment also uses different materials as its functional materials, such as silicone oils or gases. In contrast, a freezer uses an electric motor as its power source.
There is more burned food than in the refrigerator because the freezer maintains a colder temperature than the fridge. This will cause a burn if the nutrition inside the freezer is not wrapped well.
How to turn the freezer into a refrigerator?
A freezer can never be used as a refrigerator because the freezer runs at a lower temperature than the fridge or compartment, which maintains a temperature between -18 and -25 °C.
The freezer only has a temperature range from 0 to 5 °C. However, the freezer burns food quickly if the foods inside the freezer are not wrapped well.
However, a compartment with a temperature can be used as a refrigerator by defrosting it once in a while.
Once the compartment is fully defrosted, foods placed inside it will maintain their temperature and freshness for at least seven days without getting burnt.
Freezer burn food will be affected when frozen food defrosts because the temperature causes the burn.
How much should I fill my freezer?
Filling your freezer to about 75-80% capacity would be best. Overfilling your freezer can cause it to work harder to maintain the temperature, reducing its efficiency and increasing energy consumption.
In addition, if you leave too much room in the freezer, the temperature may fluctuate, hurting the food you keep inside.
Can I store food in the refrigerator or freezer for an indefinite period?
No, you cannot store food in the refrigerator or freezer indefinitely. While freezing can prolong the shelf life of food, it does not make it last forever.
Frozen food can still go bad over time. And it is recommended to use or consume frozen food within a reasonable time frame to ensure its quality and safety.
How can I improve the energy efficiency of my refrigerator or freezer?
The energy efficiency of your fridge or freezer may be increased by:
- Keep the door closed as much as possible to prevent cold air from escaping.
- Ensure the door seals are tight and in good condition to prevent air leaks.
- Keep the coils clean and free from dust and debris to improve cooling efficiency.
- Keep the refrigerator or freezer away from heat sources.
- Set the temperature to the recommended level and avoid adjusting it frequently.
