The brand's two-chamber refrigerators Atlant have earned a reputation as reliable “workhorses” in the post-Soviet space, however, many owners are faced with a misunderstanding of the operating principles of the thermostat. The question often arises: what temperature should be in the freezer to ensure long-term storage of products without loss of their taste and structure. Optimal temperature conditions is a critical parameter on which not only the shelf life of stocks depends, but also the energy consumption of the entire system.
Unlike old single-chamber models, modern two-chamber units allow you to regulate the climate in each compartment more flexibly. However, even with a powerful compressor, the device cannot always maintain the declared parameters if the operating rules are violated or there is a failure in the calibration of the sensors. In this article, we will examine in detail the physics of the freezing process, standards for various products and algorithms for action in case of deviations from the norm.
Understanding how your Atlantworks will help you avoid common mistakes, such as overloading the chamber with warm products or setting the regulator to extreme positions unnecessarily. Correct settings extend the life of the compressor and preserve vitamins in vegetables and meat for many months.
Standard temperature indicators for the freezer
According to international standards and technical data sheets of most models Atlant, the operating temperature in the freezer compartment must be in the range from -6 to -24 degrees Celsius. However, to ensure complete freezing and storage of products for a long time (up to 12 months), it is recommended to maintain a value of about -18 degrees Celsius. It is at this indicator that the biochemical processes in products stop, and bacteria lose their ability to reproduce.
Many users mistakenly believe that the colder the better. This is not entirely true. Setting the controller to maximum cooling (for example, -24°C) leads to increased load on the compressor and increased energy consumption, while the nutritional value of the products does not increase. Moreover, at too low temperatures, some types of vegetables and fruits may lose their texture more quickly.
It is important to note that the actual temperature at different points in the chamber may vary slightly. It is always colder at the back wall, where the evaporator is located, than at the door. Therefore, the distribution of products is important: it is better to place meat and fish closer to the source of cold, and semi-finished products in containers - in less cold areas.
⚠️ Attention: If you notice that the ice in the freezer has become loose or an unpleasant odor has appeared, this may indicate that the temperature has risen above -12°C, even if the indicator shows normal. Check the tightness of the seal.
For accurate control, it is recommended to use an external thermometer, since the built-in sensors in budget models Atlant may have an error of 2-3 degrees. Regular monitoring will help to detect the onset of defrosting in time.
Deciphering the thermostat scale and operating modes
Temperature control in refrigerators Atlant is most often carried out by a mechanical thermostat located inside the refrigeration compartment or on the body. The scale usually has divisions from 1 to 7 (or from Min to Max). It is important to understand that the numbers on the regulator do not directly correspond to degrees Celsius, but indicate cooling intensity.
In the standard position (usually division 3), the temperature in the freezer is maintained at about -18°C. Shifting the knob towards larger numbers enhances the work of the compressor, lowering the temperature, but increasing the time of its continuous operation. A shift towards lower numbers, on the contrary, allows the camera to “rest” longer, raising the temperature inside.
There is also a special “Super Freeze” mode (often indicated by a snowflake or a button with the corresponding inscription). When activated, the compressor runs continuously, ignoring thermostat signals, to quickly freeze large volumes of fresh food. You cannot use this mode all the time - this will lead to freezing of the evaporator and breakdown.
If you have an electronically controlled model, the adjustment is made more precisely, in 1-degree increments. Here you set exactly the target value, and the “brains” of the refrigerator themselves decide how long the compressor should operate. This is a more energy-efficient option, but it is sensitive to power surges in the network.
Factors affecting temperature stability
Even a working refrigerator Atlant may not maintain the temperature if its operating conditions are violated. The first and most important factor is environment. If the refrigerator is located near the radiator, in direct sunlight or in an unheated room in winter, the thermoregulation system may not work correctly.
The second factor is the fullness of the chamber. An empty freezer loses cold faster when the door is opened, since the air there does not have thermal inertia. On the contrary, a chamber tightly packed with food (especially if there are frozen briquettes there) works as a cold accumulator and holds the temperature better. However, it is also impossible to fill the chamber “to capacity”, blocking the air circulation channels.
The third, and often ignored, factor is the condition of the rubber seal on the door. If it has dried out, become dirty or deformed, warm, moist air from the room constantly enters the chamber. This leads not only to an increase in temperature, but also to the formation of a thick ice crust (“fur coat”) on the walls.
- 🧊 Frequent opening of the door significantly increases the temperature inside, forcing the compressor to work harder.
- 🥩 Loading a large amount of warm products requires turning on the “Super Freeze” mode, otherwise the temperature in the chamber will sharply will grow.
- 💨 Impaired air circulation due to improperly laid out bags can create “heat pockets” where food will spoil faster.
It is also worth considering the technical condition of the refrigerator. A clogged capillary tube, a freon leak, or a malfunction of the thermostat are all technical reasons that cannot be solved by simply reconfiguring the regulator knob.
Comparison of temperature conditions for different products
Not all products require the same storage conditions. Meat and fish really need a stable temperature of -18°C or lower to maintain cell structure and prevent fat oxidation. However, some semi-finished products or ready-made dishes can be stored at -12°C, although their shelf life in this case is halved.
Vegetables and fruits, if you store them in blast freezing, are also better kept at -18°C. At higher temperatures (-6...-10°C), enzymatic processes can continue in them, which, after defrosting, will lead to the product turning into porridge. For short-term storage (a week or two), it is permissible to increase the temperature to -12°C.
Below is a table that will help you navigate the optimal conditions for various categories of products in the freezer Atlant.
| Product type | Recommended temperature | Shelf life (max) | Features |
|---|---|---|---|
| Meat (beef, pork) | -18°C and below | 12 months | Requires deep freezing |
| Fish and seafood | -18°C ... -24°C | 6-8 months | Fatty fish can be stored less |
| Vegetables and fruits | -18°C | 12 months | Needs preliminary blanching |
| Semi-finished products | -12°C ... -18°C | 3-4 months | Sensitive to changes |
| Bakery products | -10°C ... -15°C | 2-3 months | May become stale during long-term storage |
Using the correct temperature allows you not only to preserve food, but also to save your budget by reducing the amount of spoiled food thrown away. Remember that re-freezing already defrosted products is strictly not recommended, as it destroys their structure and promotes the growth of bacteria.
Diagnosis of problems: why the cold does not stay cold
If you notice that the food in the freezer Atlant began to thaw, and there is no frost on the walls or, on the contrary, a thick layer of ice has formed, it is necessary to carry out diagnostics. First of all, check whether the defrost button (if there is one) is stuck or whether the regulator is in the “0” or “Min” position.
A common reason for an increase in temperature is freezing of the evaporator. In refrigerators with manual defrosting (and many double-chamber Atlanta are of this type, especially in the freezer), the ice crust acts as a heat insulator. The compressor hums, trying to cool the chamber, but the cold does not pass through the layer of ice to the food. In this case, complete defrosting is required within 10-12 hours.
If the situation has not changed after defrosting, the problem may be more serious. This could be a refrigerant (freon) leak. Signs: the compressor works constantly or very rarely (if the protection has tripped), the freezer is warm, and in the refrigerator compartment the temperature may be normal or also elevated. It is also possible that the thermostat fails: it simply “does not see” that it is warm in the chamber and does not turn on the motor.
☑️ Diagnostics of the freezer
Another hidden reason - Fan malfunction (in models with No Frost). If the fan does not spin, cold air does not enter the chamber, although the evaporator may be icy. In such cases, you often hear extraneous noise or hum from the freezer.
Rules for defrosting and caring for the freezer
To maintain the correct temperature in a two-chamber refrigerator Atlant it is necessary to defrost regularly. The frequency depends on the rate of ice growth, but usually this needs to be done 2-3 times a year. Ignoring this procedure leads to the fact that the useful volume of the chamber decreases and the load on the unit increases.
The defrosting process should be natural. Never use a knife, screwdriver or other sharp objects to chip ice. A breakdown of the evaporator will lead to an immediate release of freon and expensive repairs, which are often not economically feasible. It is also not recommended to pour hot water, since a sharp temperature change can damage the plastic and rubber seals.
After defrosting, the chamber must be thoroughly washed using a weak soda solution or a special product for refrigerators, and wiped dry. This will remove bacteria and odors that may have accumulated during use. Only after this can you turn on the refrigerator and load food.
⚠️ Attention: In modern models Atlant with the No Frost system, complete defrosting may not be required for years, but hygienic washing is recommended at least once a year. Check the instructions for your specific model.
Regular maintenance includes checking the cleanliness of the condenser (the grille at the back of the refrigerator). If it is clogged with dust and animal hair, heat exchange is disrupted, the compressor overheats and cannot provide the required temperature in the freezer.
Frequently asked questions (FAQ)
Why is the temperature in the Atlant freezer -24 degrees, although the regulator is set to 3?
This may indicate a malfunction of the thermostat, which is “stuck” in the on position, or a clogged capillary system, due to which the refrigerant does not circulate normally, causing local hypothermia. Also check if the “Super Freeze” mode is turned on.
Can food be stored at -6 degrees in the freezer?
Temperature -6°C is only permissible for short-term storage (several days) or for products that will be cooked immediately. For a long-term supply of meat and fish, this is not enough, since the bacteria do not completely stop their activity.
How to understand that there is little freon in a two-chamber Atlanta?
Signs of a freon shortage: the compressor works almost non-stop, the freezer cools weakly or only at the back wall, and the refrigerator compartment may be warm. Also, there may not be uniform frost on the tubes inside the freezer.
Does placing the refrigerator near a window affect the temperature in the freezer?
Yes, direct sunlight heats the body of the refrigerator, causing the thermostat to turn on the compressor more often. This can lead to the temperature inside the freezer fluctuating and rising above normal, especially in summer.
What to do if after defrosting the temperature does not drop below -10?
If after 12 hours of defrosting and idling the temperature does not drop, there may be a malfunction of the compressor, a freon leak, or a failure of the starter relay A call to a technician is required for diagnostics.
