Modern refrigerators are complex technical devices where every detail plays a role in maintaining the freshness of products. One of the key technologies introduced by Samsung into its models was the system All Around Cooling. Users often come across this term when choosing a new technology, but do not always understand its practical meaning. Essentially, this is an intelligent cold air distribution system designed to eliminate temperature differences inside the chamber.
Unlike older models, where the cold flow came from only one point, many holes are used here on each shelf. This allows you to maintain a stable temperature no matter how often you open the door. Air circulation happens evenly throughout the entire volume, which is critical for products sensitive to thermal shocks. If you're wondering whether it's worth paying extra for this feature, the answer lies in the design details and your storage habits.
Understanding how the system works will help you load shelves correctly and use the unit's capabilities more efficiently. Technology It doesn't just cool, it creates a microenvironment that extends life suitability of vegetables, fruits and ready meals. Next, we will analyze in detail the mechanics of the process, compare it with other solutions and give practical advice on operation.
The principle of operation of the All Around Cooling system
The main idea of the technology is to create multiple cold air outlet points. Inside the refrigerator compartment, on the back wall and often on the side partitions between the shelves, there are special deflectors. Temperature sensorsinstalled in different zones, constantly read data and transmit it to the control module. Based on these readings, the system regulates the intensity of air supply through certain openings.
When you open the door, warm air gets inside and the temperature rises sharply. The system All Around Cooling reacts to this instantly, launching increased circulation through all available channels. This allows you to quickly restore the set mode without waiting for the cold to “fall” from top to bottom, as happens in classic models with one upper nozzle. Uniformity is the key word here.
It is important to note that the air flows are directed so as not to overdry the products. Humidity in the storage areas of vegetables and fruits it is maintained at an optimal level due to the special geometry of the channels. Cold air flows around the food from all sides - top, bottom, left and right, hence the name "All Around". This prevents the formation of local “warm pockets” where bacteria could multiply more actively.
⚠️ Attention: Do not block the air outlets with food or packaging. Blocking the channels disrupts circulation and forces the compressor to work with increased load, which leads to excessive energy consumption.
The operating mechanism can be described as a dynamic balance. If you put a hot dish (which, however, is not recommended), the system will increase the cooling power in the area where the heat surge is recorded. Algorithm The operation of the fan and dampers is synchronized to minimize noise and energy consumption during quiet periods.
Key differences from standard cooling systems
To understand the value of the technology, it is necessary to compare it with traditional approaches. In conventional refrigerators without this system, cooling is often uneven. Cold air is heavier than warm air, so it sinks, creating a temperature gradient. It can be much warmer on the top shelf than on the bottom. The system All Around Cooling eliminates this problem by ensuring the same temperature at all levels.
Another important difference concerns the speed of mode recovery. After loading groceries from the store, a standard refrigerator takes longer to “grab” the heat. On Samsung models with this feature, this process is faster thanks to distributed threads. This is especially important for meat, fish and dairy products, which spoil with the slightest heating.
Let's look at the main differences in the table for clarity:
| Comparison parameter | Standard system | All Around Cooling System |
|---|---|---|
| Cold distribution | Uneven, gradient from top to bottom | Uniform throughout the entire volume |
| Cooling rate | Slow, depends on natural convection | High, forced circulation |
| Reaction to door opening | Late, long recovery cycle | Instant, fast stabilization |
| Humidity retention | Possible over-drying of food | Optimized to maintain freshness |
Energy efficiency is also worth mentioning. Although the fan consumes electricity, the overall system efficiency is higher. The compressor turns on less often and works for less time, since Heat transfer it happens better. In the long run, this can lead to savings on energy bills, despite the higher initial cost of the device.
Benefits for food preservation
The main goal of any refrigerator is to extend the life of food. Technology All Around Cooling copes with this better than many analogues. Due to the absence of sudden temperature changes, the structure of the products is not destroyed. Vegetables and fruits stay crispier longer because they are not exposed to “heat shock” every time you take milk from the bottom shelf.
The preservation of taste deserves special attention. With uneven cooling, some foods may freeze at the back wall, while others begin to spoil at the door. In the Samsung system, the temperature is equalized, which prevents local freezing. Vitamins and beneficial microelements in fruits are retained in a larger volume.
List of benefits for various product groups:
- 🥦 Vegetables and greens: no wither and are not covered with condensation due to humidity control.
- 🥩 Meat and fish: quickly cool after purchase, which blocks the growth of bacteria.
- 🍰 Prepared dishes: do not dry out and retain their taste even with frequent opening of the door.
- 🥛 Dairy products: remain fresh until the last day of the expiration date indicated on the package.
In addition, the system helps to avoid the appearance of unpleasant odors. Constant air circulation through filters (if provided by the model) or simply active air exchange prevents odors from stagnating. Hygiene inside the chamber is maintained at a high level, which is especially important for families with small children.
Impact on energy consumption and noise
Many users are afraid that a complex system with many fans will be noisy. However, Samsung engineers paid special attention to this. The fans in the system All Around Cooling are designed to produce minimal noise. In practice, this means that the hum of equipment is practically inaudible against the background of household sounds, unless the refrigerator is located in close proximity to the sleeping place.
As for energy consumption, the principle of “smart” control works here. Sensors prevent the system from running idle. If the temperature is stable, the fan speed is reduced. This makes modern Samsung models one of the most economical in their class. Energy efficiency class A++ or A+++ is achieved precisely due to such optimized algorithms.
⚠️ Attention: The noise level may increase if the refrigerator is installed unevenly or close to the wall. Always leave the recommended clearance for ventilation of the compressor and heat exchanger.
It is important to understand that the initial start-up or Power Cool/Power Freeze mode may be accompanied by a more active sound of the fans. This is a normal operating process and indicates that the system All Around Cooling is actively carrying out its task of equalizing temperatures.
Why might the refrigerator hum louder than usual?
If you hear increased noise, check to see if food is pressed against the vents. Also, the humming may increase on hot days when the system works harder to maintain the temperature inside.
Comparison with Twin Cooling Plus technology
Often buyers confuse the All Around Cooling system with another popular Samsung development - Twin Cooling Plus. It is important to distinguish between these concepts. All Around Cooling is responsible for circulation air inside one chamber (usually a refrigeration chamber). Twin Cooling Plus is a system that involves the presence of two independent cooling circuits: one for the refrigerator compartment, the other for the freezer.
In models with Twin Cooling Plus, odors from the freezer will never enter the refrigerator compartment, since the air flows are physically separated. The All Around Cooling system can work either in conjunction with Twin Cooling or independently in models with one compressor. If both technologies are indicated in the description of the refrigerator, this means the highest level of climate control.
Let's consider the differences in functionality:
- ❄️ All Around Cooling: Uniform distribution of cold inside the chamber, eliminating warm zones.
- 🔄 Twin Cooling: Separation of air flows between the refrigerator and freezer, independent humidity control.
- 🛡️ Protection: All Around Cooling protects against changes when opening the door; Twin Cooling protects against mixing odors.
For the user, having both systems is an ideal option. However, if there is a choice, then All Around Cooling is more critical for the daily preservation of freshness of food on the shelves of the refrigerator, since this is where we store perishable food that we get most often.
Recommendations for use and care
So that the system All Around Cooling works correctly for a long time years, you must follow simple operating rules. The main thing is not to overload the shelves. Dense packing of food blocks air circulation channels. There should be a gap of at least 1-2 centimeters between the packages for the free passage of air masses.
Regular cleaning is also important. Dust and crumbs can clog the vents, reducing efficiency. Wipe the areas around the vents with a damp cloth every time you deep clean your refrigerator. Do not use aggressive chemicals, which can damage the plastic elements of the system.
☑️ Checking the operation of the cooling system
If you notice that food has begun to deteriorate faster or condensation has appeared on the walls, defrosting (if the model is not NoFrost) or diagnostics of the sensors may be required. In models with Full NoFrost and All Around Cooling, ice formation is minimal, but checking the drainage hole will not be superfluous.
⚠️ Attention: Do not try to disassemble the back panel inside the refrigerator to clean the channels yourself. This can damage fragile plastic air ducts and compromise the seal of the system.
Frequently asked questions (FAQ)
Do you need to defrost a refrigerator with the All Around Cooling system?
Most modern Samsung models with this technology also implement the NoFrost system, which eliminates the need for manual defrosting. However, if you have a model with a drip system (crying evaporator) in the refrigeration chamber, but with All Around Cooling, then once every 6-12 months you may need defrosting for prevention.
Why is cold air blowing in the refrigeration chamber?
This is normal operation of the All Around Cooling system. Perceptible air flows indicate that the fans are functioning and distributing the cold throughout the entire volume. If the flow is too strong and blows food out, check the temperature settings or the position of the dampers.
Is it possible to turn off the All Around Cooling system?
No, this is a basic design feature of the refrigerator and does not have a shutdown button. It works in the background, controlled electronically. You can disable only the accelerated cooling modes (Power Cool), but not the circulation system itself.
Does this system affect the formation of ice on products?
On the contrary, thanks to the uniform temperature distribution and humidity control, the likelihood of ice crust formation on products (for example, meat or herbs) is significantly reduced compared to conventional ones refrigerators.
