Can I Use My Freezer as A Cooler?
A cooler is designed to keep beverages cold, commonly made of hard plastic or metal. The unit typically consists of a lid and the container itself.
We can find coolers for sale in every grocery and convenience store that stocks cold drinks and camping stores. When we say “cooler,” we typically mean a portable device; these come in different sizes depending on their intended needs.
Yes! You can use your freezer as a cooler. Here’s how
Prepare the Freezer: Start by unplugging it and removing all the food items. Clean the freezer thoroughly and remove any ice build-up or frost build-up.
Clean the Freezer’s walls and door: The walls of your freezer will be its fastest cooling surfaces, which is why they need to be clean. Make sure to wipe them down with a cloth dampened with some water. If there is any ice build-up or frost build-up, scrub it off.
Run the Defrost cycle: You can use the defrost cycle in your freezer to remove any ice build-up on the inside walls of the freezer. While running the defrost cycle, you can remove any ice build-up still on the inside wall of your freezer.
Remove any Finish Coatings: If there are any finish coatings on the inside walls of your freezer, such as that clear plastic covering the top of your freezer, you can easily remove those with a damp cloth or sponge.
Remove the Plastic film from the freezer’s interior: The plastic film covering the inside of your freezer keeps it cool and protects it from damage.
If you want to remove it, buy a small, handheld vacuum cleaner to remove dust and lint. You can then use it on your freezer’s interior walls.
Install insulation materials: Once you’ve removed all those things from your freezer, install insulation materials like foam or felt onto the inside walls of your freezer. The insulation materials will keep the freezer cool when it’s turned off.
Plug in and Turn on your freezer: Now that you’ve done all that work, you can plug in your freezer and turn it on. You can then enjoy your cold food whenever you want it.
How Do I Turn My Freezer into A Cooler?
- Unplug the Freezer: Make sure the freezer does not boast a connection to any power source for safety reasons.
- Empty the Freezer: Remove all items from the freezer and temporarily store them in another location.
- Clean the Freezer: Thoroughly clean the interior using a mild cleaning solution and warm water. Rinse off any residue and allow it to dry completely.
- Prepare the Cooling Elements: You can use ice packs or even frozen water bottles as cooling elements. Please place them in the freezer to get them chilled.
- Arrange the Cooling Elements: Once the ingredients are sufficiently chilled, arrange them evenly in the freezer. You can place them on the shelves or in any available space.
- Monitor Temperature: Use a thermometer to monitor the temperature inside the freezer. You may need to periodically rotate or replace the cooling elements to maintain the desired temperature.
- Insulate the Freezer: To improve the cooling efficiency, you can insulate the freezer by covering it with blankets, towels, or foam insulation. This will keep the cold air inside and prevent warm air from entering.
- Use as a Cooler: Once the cooling elements are in place and the freezer is insulated, you can use it as a cooler by placing your food, drinks, or other perishable items inside.
Make sure to close the freezer door tightly to maintain the cold temperature.

Do Freezers Have Ventilation?
Freezers typically have some form of ventilation to ensure proper airflow and cooling. Ventilation is crucial for maintaining the desired temperature inside the freezer and preventing excessive heat build-up.
There are a few different ways in which freezers may get designed to incorporate ventilation:
Air Vents: Many freezers have built-in air vents or grilles that allow air to circulate. These vents are usually located at the back of the freezer or along the sides.
They enable the movement of cold air produced by the freezer’s cooling system, helping to distribute the cold air evenly and preventing hot spots.
Condenser Coils: Freezers also have condenser coils, which remove heat from the interior and release it to the surrounding environment.
These coils can be located either on the back or underneath the freezer. Adequate ventilation around the condenser coils is essential to ensure efficient heat dissipation.
Fan Systems: Some freezers incorporate fans to improve air circulation. These fans help to distribute cold air more effectively, reducing temperature variations and ensuring consistent cooling throughout the freezer’s interior.
The fans also assist in dissipating heat from the condenser coils.
Why Does A Room Get Hotter When The Fridge Is Open?
When you open a refrigerator door, the room tends to get hotter due to a combination of factors. Here’s a breakdown of why this happens:
Heat exchange: Refrigerators remove heat from the interior and release it to the surrounding environment.
The cooling process inside the fridge involves removing heat from the food and expelling it through the condenser coils at the back or bottom of the refrigerator.
When you open the fridge door, the heat that was supposed to be removed outside escapes into the room, raising its temperature.
Less insulation: The thicker insulation on the back of the fridge absorbs more heat. In a less insulated area, surrounding air can come into contact with the cold food and replace the heat initially expelled.
The surrounding air also absorbs heat from your body!
Evaporative Cooling: As warmer air comes in contact with the colder food, it quickly absorbs moisture which falls to the floor as condensation.
Conduction: The metal door, ice dispenser, shelves, and other metal parts of the fridge conduct heat from the room through direct contact.
Converting A Chest Freezer into An Ice Bath or Ice Plunge
Select a suitable chest freezer: Choose a chest freezer that is large enough to accommodate your body comfortably. Measure the dimensions of the freezer to ensure it can fit you while lying down or sitting comfortably.
Empty and clean the freezer: Remove all items and unplug them from the power source. Clean the freezer’s interior thoroughly to remove dirt, debris, or odors. Use a mild detergent and warm water, and allow it to dry completely.
Install a drain: To prevent the ice bath from overflowing, you’ll need to install a drain in the bottom of the freezer.
You can use a rubber stopper with a hole drilled into it, connected to a length of PVC pipe, or a flexible hose. Ensure the drain extends outside the freezer or into a nearby drain to remove melted ice.
Insulate the lid: Since the chest freezer lid boasts a design to keep cold air, you’ll need to insulate it to maintain the cold temperature.
Apply weatherstripping tape around the edges of the lid to create an airtight seal. This will help minimize heat transfer and keep the water colder for longer.
Fill the freezer with water: Fill the freezer with water to the desired depth for your ice bath or plunge.
I recommend you start with a lower water level and gradually increase it over time to acclimate your body to the cold temperature.
Monitor the temperature: Use a digital thermometer to monitor the temperature of the water regularly. Adjust the temperature by adding or removing ice as needed.
Consider using a temperature controller to maintain a consistent temperature throughout your cold therapy session.
Ensure safety precautions: Safety should always be a priority. Before entering the ice bath or plunge, ensure you can exit quickly.
Consider having a timer or someone nearby to assist you. It’s also essential to start with shorter sessions and gradually increase the duration as your body adapts to the cold.
Does A Freezer Get Cold Faster Than A Fridge?
Yes! A freezer does get cold faster than a fridge because of the:
Temperature Setting: Freezers boast designs to maintain much lower temperatures than fridges.
The typical temperature range for a freezer is between -18 to -23 degrees Celsius (-0.4 to -9.4 degrees Fahrenheit), while fridges usually maintain temperatures around 0 to 4 degrees Celsius (32 to 39.2 degrees Fahrenheit).
The lower temperature setting in freezers allows for faster cooling.
Freezer Door: A freezer door is a highly efficient insulator that helps to maintain much lower temperatures within the freezer.
The typical thickness of the door of a standard freezer (seamless) is 0.5 mm to 0.6 mm (0.02 inches to 0.024 inches). A regular fridge door is only 0.2mm thick (0.008 inches).
Thermal Energy: Thermal energy refers to the heat energy of any thermal system (such as a freezer or fridge).
The thermal energy within the freezer will speed up the cooling process, while the thermal energy in a refrigerator will slow down the cooling process.
Thermal Mass: Freezers have much more thermal mass than fridges due to their larger size (usually).
This means that they can hold more heat for extended periods. This means the heat boasts continuous removal from the freezer, even in standby mode.
How To Turn an Air Conditioner into A Refrigerator?
Gather some tools and materials: You’ll need a basic understanding of HVAC systems and the following tools and materials:
An air conditioner unit, refrigerant, refrigeration gauge set, refrigeration tubing, a refrigeration compressor, a condenser, an evaporator, a filter drier, and copper tubing.
Disconnect the power supply: Before starting any work, ensure the air conditioner gets disconnected from the power source. Safety should always be a top priority.
Remove the existing components: Start by removing the existing elements of the air conditioner that are not necessary for refrigeration.
This typically includes the blower motor and fan, as refrigerators don’t require air circulation like air conditioners.
Install the evaporator: Place the coil in the desired location, usually inside the refrigerator cabinet. This component absorbs heat from the refrigerator’s interior, causing the temperature to drop.
Install the condenser: Mount the condenser coil, which dissipates heat from the system, in an appropriate location outside the refrigerator. Ensure it has proper ventilation to maintain efficient cooling.
Connect the components: Use copper tubing to connect the evaporator and condenser coils. Install a filter drier in the line to remove any contaminants or moisture that could harm the system.
Connect the refrigeration compressor to the condenser and evaporator coils.
Charge the system with refrigerant: Use a refrigeration gauge set to evacuate the system and remove any existing air or moisture.
Then, charge the system with the appropriate refrigerant according to the manufacturer’s specifications. Be sure to follow all safety guidelines and local regulations when handling refrigerants.
Convert The Air Conditioner to The Freezer
- Gather the necessary equipment: Including a pressure gauge, refrigerant, a compressor bypass valve, and appropriate tubing and fittings.
- Calculate the amount of refrigerant needed: Remember that the unit doesn’t work by only cooling but by removing moisture. Hence, you need to calculate the weight of the water that requires removal from the air.
- Remove the indoor compressor: Remember that the refrigerant lines are still attached. This may become very heavy once you empty it; get prepared.
- Switch to the bypass mode on the compressor: This boasts control by a switch or a solenoid valve; once you turn it off, any gas that enters it will not come out and will go directly to your new conversion.
- Connect the refrigerant line to the new conversion: Use the necessary lengths of tubing to connect the new transformation.
The size of these must be enough to allow your freezer to fit in a convenient space and still have enough room for its moving parts.
- Connect the airlines to the conversion: Connect all necessary air lines to your new conversion. The important thing here is to ensure that all of your connections are leak-free.
- Place in the freezer: Once you’ve connected all the refrigerant hoses, you can start freezing or prepare your compressor to burn.
- Let it thaw out: Leave your conversion in the freezer for up to a week. I recommend waiting at least 3 to 4 days before taking it out so that the paint on your unit doesn’t crack.
- Service the unit: Needless to say, your condenser coils will get pretty dirty after all of that. So, you’ll need to clean them before you can use the unit again.
- Reinstall the indoor compressor: After it has thawed out, slide it back into place, secure it using screws or clamps, and install new refrigerant lines. Remember to re-attach them to the outdoor unit as well.
- Store the unit: After you’ve cleaned the coils and installed new refrigerant lines, you’ll probably want to store the unit for an extended period.
Manufacturers design coolers to cool down food and beverages; that’s it. Refrigerators, on the other hand, have a secondary function of keeping food from spoiling and adding to the food safety of the fridge.
The difference is mainly in size; they are much bigger than a cooler, but let’s not go there. Re-purposing an air conditioner for refrigeration can also be done.
