Correct operation of the freezer compartment directly affects the safety of food and the service life of the compressor. Owners of Belarusian equipment often wonder what specific indicators are considered standard for models Atlant. Correctly set parameters ensure that meat, fish and vegetables remain fresh for a long time, maintaining their structure and taste.
Modern two-chamber units allow you to adjust the degree of cooling manually or automatically. Understanding the principles of operation thermostat will help you avoid common mistakes, such as excessive energy consumption or, conversely, spoilage of supplies due to insufficient cold. In this article we will analyze the technical nuances and standards adopted by the manufacturer.
It is worth noting that different models may have their own characteristics in control. This applies to both mechanical handles and electronic display panels. Regardless of the type of control, the physics of the process remains the same: the compressor operates until a predetermined threshold is reached, after which it turns off.
Standard temperature indicators for Atlant freezers
According to technical regulations and international standards, the optimal value for long-term storage of products is considered to be the range from minus 18 to minus 24 degrees Celsius. It is at these levels that biochemical processes in tissues stop, which prevents the proliferation of bacteria. Models Atlant are designed to maintain this mode with high accuracy, provided the system is in good working order.
It is important to distinguish between the concepts of “storage temperature” and “freezing temperature”. The first parameter must be stable, and the second implies a short-term decrease in values to extreme levels (about minus 24...minus 30 °C) for quick processing of fresh products. If you have loaded a full chamber of fresh meat, the standard mode may not be enough to maintain quality.
The manufacturer indicates in the product passport that the climate class also affects the operation of the unit. For most regions of Russia and Belarus, class models N (normal) and SN (subnormal) are suitable. They work effectively at ambient temperatures from +10 to +32 degrees, providing the necessary minus values inside the chamber.
When operating in the “Super Freeze” mode, the indicators may drop below standard values. This is a normal situation provided for by the design. However, it is not recommended to constantly keep the equipment in this mode, as this increases the load on the motor and energy consumption.
How to adjust the temperature in different models
The adjustment process depends on the type of control installed on your refrigerator. In older or budget series, a mechanical one is used, which is a rotary knob with divisions. More advanced models have an electronic control panel with a digital display where you can set the exact value. thermostat, which is a rotary knob with divisions. More advanced models have an electronic control panel with a digital display where you can set the exact value.
For mechanical regulators, the scale usually varies from 1 to 7 or from Min to Max. A simple rule applies here: the higher the number, the colder it is inside. Setting the knob to maximum does not mean that the temperature will immediately drop to the extreme values; this is only a signal to the compressor to work longer without interruption.
In electronic models, adjustment is made by sequentially pressing the buttons. Typically you need to press the temperature setting button (often indicated by a snowflake or thermometer symbol) and then use the "+" or "-" buttons to change the value. After selecting the desired parameter, the system remembers the command in a few seconds.
☑️ Setting up the electronic thermostat
If you changed the settings, do not expect instant results. The refrigeration unit needs time to rebuild the cycles and stabilize the climate inside the chambers. Typically, this process takes from 2 to 5 hours, depending on the load on the shelves.
Operating modes and the super freezing function
Many users do not fully understand the purpose of the function Super Freeze or “Super freezing”. This mode is designed for fast freezing of large volumes of fresh food. When activated, the compressor goes into continuous operation, ignoring standard shutdown thresholds, until the temperature reaches critically low values.
This mode should be used with caution. If left on for several days, excess ice may form in the compartment and food that has already been frozen may dry out (freezer burn effect). In mechanical models, this mode is often activated by a separate red button or switch.
In electronic systems, control of this process is automated. You can set a timer after which the refrigerator will automatically return to normal storage mode. This prevents the human factor and forgetfulness when the user forgets to turn off the enhanced freezing.
⚠️ Attention: Long-term operation in super freezing mode (more than 24-48 hours without loading fresh food) leads to overheating of the compressor and shortening the life of the refrigerator. Use the function only when necessary.
It is also worth mentioning the “Vacation” mode. Although it is primarily intended for the refrigerator compartment, in some models it also affects the operation of the freezer, switching it to economy mode if it is empty. However, this is less relevant for the freezer, since it must work constantly.
Factors affecting chamber cooling
Even with the correct settings, the actual temperature can fluctuate (fluctuate) under the influence of external and internal factors. One of the key points is loading density. An empty freezer cools down faster, but it also loses cold faster when the door is opened. A loaded chamber operates more stable, since frozen foods act as cold accumulators.
The tightness of the door seal is another critical parameter. If the rubber is worn out, dirty, or the door is warped, warm, moist air will constantly flow inside. This will lead not only to an increase in temperature, but also to the active formation of a snow coat on the evaporator The frequency of opening the door also plays a role. Each opening starts the heat transfer process. If you often look into the freezer or keep the door open for a long time, the compressor is forced to work harder to compensate for the loss of cold. on the evaporator.
How often the door is opened also plays a role. Each opening starts the heat transfer process. If you look into your freezer often or leave the door open for a long time, the compressor is forced to work harder to compensate for the loss of cold.
The location of the refrigerator in the room matters. Proximity to heating appliances, direct sunlight, or lack of clearance for rear ventilation make it difficult to remove heat from the condenser. As a result, the cooling efficiency drops, and it becomes more difficult to achieve the required minus 18 degrees.
Table of correspondence between modes and temperatures
For the convenience of users, below is a table that will help you navigate the values of the divisions of the mechanical regulator and the corresponding approximate temperature conditions. Remember that the exact values depend on the specific model and operating conditions.
| Regulator division | Approximate t° (Frost) | Operating mode | Recommendation |
|---|---|---|---|
| 1 (Min) | -6...-8 °C | Economy | For short-term storage |
| 3 (Average) | -18 °C | Normal | Optimal for everyday use |
| 5 (Max) | -24...-26 °C | Intensive | For freezing large volumes |
| Super Freeze | up to -30 °C | Maximum | Turn on for no more than 24-48 hours |
As can be seen from the table, the middle position of the handle (usually the number 3 or 4) is the most rational choice for year-round use. Turning the regulator to maximum unnecessarily will not make the products “more frozen” in a qualitative sense, but will force the equipment to work at the limit of its capabilities.
Diagnostics of problems with temperature conditions
If you notice that the food in the freezer has begun to deteriorate, an unpleasant odor appears or the ice is melting, you need to carry out diagnostics. The first step should always be to check the actual temperature. To do this, you can use a regular outdoor thermometer or a special kitchen thermometer, leaving it in a glass of water or between bags for 6-8 hours.
A common cause of insufficient cooling is freezing of the evaporator. The ice layer acts as a heat insulator, preventing the cold from spreading throughout the chamber. In systems No Frost this may indicate a malfunction of the defrost system, and in drip systems - a violation of operating rules (open door, hot products).
It is also worth paying attention to the operation of the compressor. If it turns on too often or, conversely, does not turn on at all, the problem may be with the thermostat or start relay. Humming, clicking or complete silence of the unit are signals to call a technician.
⚠️ Attention: If you find that the back wall of the freezer is covered with a solid crust of ice, and the temperature does not drop below -10 °C, most likely, defrosting or repairing the defrosting system is required. Do not try to chip the ice with sharp objects - you may damage the evaporator.
In some cases, the problem lies in a refrigerant leak. If the compressor runs constantly, but there is no cold, and the condenser tubes (at the back or on the sides) remain cold, most likely the freon has evaporated. It is impossible to eliminate this malfunction on your own.
Rules for storing products at different temperatures
Different groups of products require different storage conditions. Meat and fish retain their properties longest at temperatures below minus 18 degrees. At higher values (for example, -6...-10 °C), the shelf life is reduced to several weeks, after which the taste and texture begin to change.
Vegetables, fruits and berries are usually frozen at shock temperatures to preserve their cellular structure. If freezing is slow, the resulting ice crystals destroy the cell walls, and when defrosted, the product turns into mush. Therefore, for preparations for the winter, it is better to use the mode Superfreezing.
Ready meals and semi-finished products are less demanding of extreme cold, but also require a stable mode. Sudden changes in temperature lead to condensation of moisture inside the package, which contributes to the development of mold even when frozen.
Shelf life at -18°C
Meat (beef, pork) - up to 12 months | Poultry - up to 9 months | Fatty fish - up to 3-4 months | Vegetables and fruits - up to 12 months|Ready meals - up to 3 months
It is also important to properly package food before storing. The use of sealed containers or special freezing bags prevents moisture from escaping and mixing odors, which is especially important for refrigerators with a general air circulation system.
Why does the Atlant freezer not maintain a temperature of -18?
There may be several reasons: thermostat malfunction, freon leak, wear of the door seal or blockage capillary tube. It is also possible that the refrigerator is overloaded or, conversely, is running idle when the door is open. Diagnostics by a specialist is required.
Is it possible to set the temperature below -24 degrees all the time?
Technically, this is possible in super-freezing mode, but maintaining this mode all the time is impractical. This will lead to excessive energy consumption and accelerated wear of the compressor. For long-term storage, -18...-20 °C is enough.
How to understand that the thermostat is broken?
If the refrigerator either does not turn on at all, or works non-stop, not reaching the desired temperature (or overcooling the chamber), most likely the thermostat or temperature sensor has failed.
Is it necessary to defrost Atlant No Frost freezer?
The No Frost system involves automatic removal of moisture, so complete defrosting is rarely required (1-2 times a year for hygiene). However, if the door does not fit tightly, ice can still form.
What temperature is considered critical for a compressor?
It is not so much the value inside the chamber that is critical, but the temperature of the motor-compressor itself. However, operating in super-freezing mode at high room temperatures (+30 °C and above) creates an extreme load on the unit.
