Refrigerators of the Belarusian brand Atlant are deservedly popular due to their reliability and affordability, but even the highest quality equipment requires proper control of operating modes. Many owners are wondering what temperature should be in the freezer to ensure that food retains its properties for as long as possible. The answer to this question is not always clear, as it depends on the type of food being frozen and the model of your device.
The correctly set temperature is not just a number on the thermostat, but a guarantee that meat, fish or vegetables will not lose vitamins and taste. If the values are set too low, the compressor will wear out, and if the values are too high, the process of food spoilage will begin even before they are consumed. In this article, we will look at the technical nuances, standards and methods for fine tuning.
Standard temperature standards for freezers
According to international standards, the freezer compartment of any household refrigerator, including models Atlant, should maintain a temperature no higher than -18°C. It is this threshold that allows you to stop the proliferation of bacteria and preserve the structure of products for up to 12 months. However, in reality, the range may vary depending on the selected operating mode and chamber load.
Modern models are often equipped with a quick freezing function, which briefly lowers the temperature to -24°C or even lower. This is necessary to shock fresh food so that ice crystals do not damage the cellular structure. For normal storage, such cold is excessive and leads to excessive energy consumption.
It is important to understand that the temperature in different parts of the chamber may differ. It is always colder near the back wall, where the evaporator is located, than near the door. Therefore, for long-term storage, it is recommended to use shelves located closer to the source of cold, and it is better to place foods that you plan to eat in the near future on the door or upper shelves.
⚠️ Attention: If your refrigerator Atlant is not equipped with a No Frost system, regular defrosting is required. A layer of ice more than 5 mm thick significantly impairs heat transfer, and the actual temperature inside the chamber may be higher than the set one.
Thermostat operating modes and their meaning
Temperature control in refrigerators Atlant is carried out through a thermostat, which can be mechanical (with a rotary knob) or electronic (with a digital display). Understanding the operating logic of this device is critical for proper operation.
In mechanical models, the handle usually has divisions from 1 to 7 (or from Min to Max). It is important to remember here: the higher the number, the lower temperature there is inside the chamber. Setting the knob to position “7” or “Max” makes the compressor work almost without stopping, which is justified only in fast freezing mode.
- ❄️ Position 1 (Min) - temperature about -6...-8°C, suitable for short-term storage or “vacation” mode.
- ❄️ Position 3-4 is the optimal mode for everyday use, providing about -18°C.
- ❄️ Position 6-7 (Max) - intensive freezing mode, the temperature drops to -24°C and below.
In electronic control everything is simpler: you set a specific value in degrees Celsius. The system itself controls the operation of the compressor to achieve the set parameter. However, even here it is worth considering that opening the door or loading warm food can temporarily upset the balance.
Chart of shelf life of food at different temperatures
The duration of storage of products directly depends on the stability of the temperature regime. Even a slight deviation from the norm can reduce the shelf life significantly. Below is a table that will help you figure out how long different categories of products can be stored at a standard temperature of -18°C.
| Product type | Temperature (°C) | Shelf life (months) | Note |
|---|---|---|---|
| Meat (beef, pork) | -18...-24 | 8-12 | Large pieces are stored longer than minced meat |
| Poultry (whole carcass) | -18...-24 | 10-12 | It is not recommended to store longer than a year |
| Fatty fish | -18...-24 | 2-3 | Fat can oxidize, changing the taste |
| Vegetables and fruits | -18...-20 | 8-10 | Require preliminary blanching |
| Semi-finished products | -18 | 3-4 | Dumplings, cutlets, pancakes |
It is worth noting that fats tend to oxidize even at low temperatures. Therefore, it is not recommended to store fatty fish or meat with a high fat content in the freezer Atlant longer than 3-4 months, even if the device technically maintains cold.
The influence of the No Frost system on the temperature regime
Refrigerators Atlant with the system No Frost (or Low Frost) work on the principle of forced air circulation. In such models, the temperature is distributed more evenly throughout the entire volume of the chamber, but they also have their own characteristics. The air here is drier, which prevents the formation of ice, but can contribute to chapping of products.
In models with No Frost, temperature sensors are often located in the cold air outlet area. This means that the response to temperature increases is faster than in static models. However, when the chamber is fully loaded, circulation may be disrupted, which will lead to the appearance of “warm zones.”
⚠️ Attention: In No Frost refrigerators, do not block the air ducts with food. Blocking air circulation will lead to a local increase in temperature and incorrect operation of the thermostat.
If you notice that food in the corners of the chamber begins to thaw and frost appears on the walls, the air exhaust system may be clogged or the fan is not working correctly. In this case, checking the temperature with a thermometer will help diagnose the problem.
Why do products dry faster in No Frost?
Dry cold air circulating in the chamber actively draws moisture from the surface of the products. To avoid this, always use airtight containers or cling film.
How to check and adjust the temperature
It often happens that the indicators on the refrigerator panel Atlant show one thing, but the reality is different. For accurate diagnosis, it is necessary to use an external measuring device. Built-in sensors may have an error or fail.
To check, you will need a regular household thermometer capable of measuring negative values. Place it between the foods in the center of the freezer, close the door and wait a few hours (it's best to leave it overnight). This is the only way to obtain objective data about what temperature actually remains inside.
- 🌡️ Place the thermometer in a glass of water or between bags of food to simulate heat capacity.
- 🌡️ Do not open the door during the measurement process, so as not to disturb the temperature regime.
- 🌡️ Take readings in the morning, before opening the refrigerator for the first time.
If the measurements showed a deviation of more than 2-3 degrees from the norm, it is necessary to make an adjustment. In mechanical models, turn the thermostat knob one notch in the desired direction and repeat the measurement in a day. In electronic models, change the settings in the menu.
☑️ Checking the temperature conditions
Typical problems and causes of deviations
If after adjusting the temperature in the freezer Atlant does not stabilize, the reason may lie in technical malfunctions. The most common of them is a refrigerant (freon) leak. In this case, the compressor works constantly, but cannot reach the desired temperature.
Another common problem is a malfunction of the thermostat. If it is stuck, the compressor may not turn on at all (temperature rises) or run continuously (temperature drops too low). It is also worth checking the rubber seals on the door: if they do not fit tightly, warm air will constantly flow inside.
A critical sign of a malfunction is the compressor operating less than 20% of the time or, conversely, continuous operation without shutdown cycles at full load cameras. In the first case, the products will flow, in the second, they will freeze in an ice ball.
Frequently asked questions (FAQ)
Why is the temperature in the Atlant freezer -10°C instead -18°C?
Most likely, the thermostat is set to the minimum position, or there are too few products in the chamber to keep it cold. The cause may also be a frozen evaporator, which interferes with heat transfer. Check the settings and defrost the refrigerator if necessary.
Is it possible to set the temperature to -30°C in a domestic refrigerator?
In most household models Atlant the minimum threshold is -24°C (fast freezing mode). Temperatures of -30°C are typical for industrial freezers. Long-term operation of a household unit at its maximum capacity will lead to rapid wear of the compressor.
How often do you need to defrost the Atlant freezer?
If you have a model with manual defrosting, the procedure should be carried out when an ice crust 5 mm thick has formed, but at least once every 6 months. No Frost models do not need to be defrosted, it is enough to wash them 1-2 times a year.
Does the temperature in the room affect the operation of the freezer?
Yes, the refrigerator Atlant is designed to operate in a certain climate class (usually from +10°C to +32°C or +43°C). If the room is too hot, the compressor will work with overload, and the temperature in the freezer may not drop to the required values.
