Correct setting of the temperature regime in refrigeration equipment is a key factor in ensuring long-term preservation of food freshness and safety of consumption. For owners of brand equipment Atlant, which is widespread in the post-Soviet space, this issue is especially relevant due to the variety of models and thermostats. An incorrectly set temperature can lead to rapid deterioration of perishable goods or, conversely, to their freezing.
The optimal climate inside the chamber depends on many factors: the location of the products, the frequency of opening the door and even the time of year. Temperature in the Atlant refrigerator regulated by a mechanical regulator or an electronic panel, and an understanding of the principles of operation These systems will help you avoid common mistakes. In this article, we will analyze in detail the standards for different departments and learn how to set up equipment as efficiently as possible.
Standard temperature indicators for different departments
The refrigerator and freezer perform completely different functions, and therefore the temperature requirements for them are radically different. In the main compartment, where prepared meals, vegetables and dairy products are stored, the climate should be stable and positive. According to the technical standards established for household appliances Atlant, the average here varies from +2 to +5 degrees Celsius.
The freezer, whether it is a separate drawer at the bottom or an upper compartment, is designed for deep freezing. Here, the temperature must drop well below zero to stop the growth of bacteria and preserve the structure of the food for months. The optimal value is considered to be -18 degrees Celsius and below. Some models allow you to set the fast freezing mode, lowering the temperature to -24 degrees, but constantly maintaining this mode is not economically profitable.
⚠️ Attention: Long-term storage of products at temperatures above -12 degrees in the freezer reduces their shelf life several times, even if they remain hard to the touch.
It is important to consider that in different areas of the same chamber the degree may differ. This is due to the physics of the movement of air masses and the design of the evaporator. Cold zones are distributed unevenly, and knowledge of this feature helps to correctly distribute supplies. For example, at the back wall, where the cooling element is usually located, it is always colder than at the door.
The influence of the type of cooling system on the distribution of cold
Equipment Atlant is available with both a classic cooling system (crying evaporator) and with more modern system No Frost. In models with a “crying” wall, cold air falls down naturally, which creates a noticeable temperature gradient. In such refrigerators, the difference between the top and bottom shelves can reach several degrees, which requires a careful approach to the placement of products.
Device equipped with the system No Frostprovide a more uniform distribution of cold thanks to forced air circulation by fans. Here, temperature changes are minimal, and the microclimate stabilizes faster after opening the door. However, even in such models there are zones with different indicators, which are important to consider for ideal storage.
Owners of models with a drip system should remember that an ice crust periodically forms on the back wall, which then melts. At this point, the temperature in the immediate vicinity of the wall may rise briefly. This is a normal operating cycle, but it affects how long the food stays chilled.
Optimal temperature on the shelves of the refrigerator compartment
Understanding the microclimate on each shelf allows you to extend the life of products. The top shelves are usually the warmest area in the refrigerator, other than the door. It is best to place products here that do not require strong refrigeration: drinks, confectionery, ready-made dishes that will be eaten during the day.
The middle and lower shelves are the main cold zone. This is where it is recommended to store dairy products, sausages, cheeses and meats. Bottom shelflocated above the vegetable drawers is often the coldest part of the refrigerator compartment in models with a top freezer. This is where you should put raw meat and fish if they are intended to be cooked in the next 24 hours.
Why can’t you put hot food?
If you put a hot pan in the refrigerator, the temperature sensor will detect a sharp heating and force the compressor to work hard until it cools the entire volume of the chamber. This also raises the temperature around nearby food, causing it to spoil.
Door shelves are the warmest and most unstable place. Due to the constant opening of the door, the temperature here often rises above +7 degrees. It is not recommended to store milk or eggs here in large quantities; it is better to reserve this place for sauces, mustard, drinks in closed bottles and other products with a long shelf life.
Operating modes of the Atlant freezer
The freezer in refrigerators Atlant usually has its own settings, independent of the main compartment, especially in dual-compressor models. The standard storage mode assumes a temperature of -18 degrees. At this value, most products retain their properties for up to 12 months. This is the gold standard for home freezing.
The “Super Freeze” function (often indicated by a snowflake or a button with the number 7 on mechanical thermostats) briefly lowers the temperature to -24 degrees. This mode is necessary when loading a large amount of fresh, not yet frozen food. It allows you to quickly freeze them without defrosting existing stocks.
| Product type | Recommended temperature | Shelf life (approximate) |
|---|---|---|
| Meat (beef, pork) | -18°C and below | 6-12 months |
| Poultry (whole carcass) | -18°C and below | 12 months |
| Fish fatty | -18°C and below | 2-3 months |
| Vegetables and fruits | -18°C and below | 8-12 months |
| Semi-finished products | -18°C and below | 3-6 months |
You should not keep the super freezing mode on all the time. This leads to excessive energy consumption and increased load on the compressor. As soon as fresh food freezes (usually after 24 hours), it is necessary to return the regulator to the standard position.
Thermostat adjustment: mechanics and electronics
Setting the temperature in the refrigerator Atlant depends on the type of control. In models with a mechanical thermostat (often one or two knobs inside the chamber), the scale usually varies from 1 to 7. It is important to remember the rule here: the higher the number, the colder it is. Setting to "1" makes the compressor work minimal, and to "7" - maximum.
The optimal position for the mechanical regulator under normal conditions is considered to be 3 or 4. This strikes a balance between sufficient cooling and efficiency. If the room is very hot (in summer), you can increase the power to 5, but it is not recommended to set it to maximum unless absolutely necessary.
⚠️ Attention: In two-compressor models with two mechanical regulators, one of them can only be responsible for the freezer. By mixing them up, you risk defrosting the main compartment or, conversely, freezing vegetables.
Electronic control, represented by a display on the door, allows you to set the exact temperature in degrees. Here the setting is intuitive: you set the desired value, and the electronics itself controls the operation of the compressor. The accuracy of such systems is higher, and the adjustment step can be 1 degree.
☑️ Checking the thermostat settings
Seasonal characteristics and external factors
The external temperature in the room directly affects the operation refrigeration equipment. In summer, when the apartment is hot, heat loss through the walls of the refrigerator increases. The compressor is forced to work longer and more often to maintain the desired indoor climate. During such periods, there may be a slight increase in the average temperature inside, especially if the refrigerator is placed near the stove or in the sun.
In winter, the situation changes. If the refrigerator is placed on an unheated loggia or in a cold corridor where the temperature drops below +10 degrees, the oil in the compressor may thicken. This leads to starting and lubrication problems. In addition, in models with No Frost the operation of the defrost system may be disrupted, since it is tied to a minimum temperature difference.
It is recommended to avoid installing the refrigerator Atlant in unheated rooms, unless otherwise specified in the manufacturer's instructions. Most household models are designed to operate in climate class SN-N-ST, which implies a minimum ambient temperature of +10 degrees Celsius.
Diagnostics of problems with temperature conditions
How to understand that the refrigerator is not working correctly without using a thermometer? There are indirect signs. If a “coat” of ice constantly forms on the walls of the refrigerator compartment, and food freezes in the depths, the thermostat may be faulty or set to maximum. Conversely, if the food quickly deteriorates, and the inside is warm and humid, this is a signal of a loss of freon or a compressor failure.
For accurate diagnosis, you can use an external thermometer. Place it on a glass of water on the middle shelf and leave it for several hours (without opening the door). This will show the actual average temperature. Remember that readings may fluctuate depending on the operating cycle of the motor.
⚠️ Attention: If you notice that the back wall of the refrigerator compartment is not covered with frost and does not “cry” (in drip models) for a long time of operation, this may indicate a refrigerant leak.
A frequent problem is a loose fit door seal. Warm air enters through the cracks, forcing the refrigerator to work in enhanced mode. Check the rubber band for cracks and dirt that may impair the seal.
Why does ice freeze on the back wall in the Atlant refrigerator?
In models with a drip system, this is normal. Moisture from the air condenses on the cold back wall, freezes, and then flows into the drain hole when the compressor turns off. If the ice does not melt and forms a fur coat, check whether the door is tightly closed or the thermostat is working properly.
Is it possible to store the Atlant refrigerator at sub-zero temperatures?
The manufacturer does not recommend operating household refrigerators at ambient temperatures below +10°C. The oil in the compressor thickens, which leads to breakdown. Storage in an unheated garage is possible only when it is turned off and provided that it is dry inside.
How often do you need to defrost the Atlant refrigerator?
Models with the No Frost system do not require manual defrosting; it is enough to wash them 1-2 times a year. Refrigerators with a drip system (crying wall) also do not need frequent defrosting, but preventive cleaning and defrosting are recommended every 6-12 months or as ice accumulates.
What does the flashing temperature indicator on the display mean?
Flashing usually indicates an increase in the temperature in the chamber above the permissible limit. This may happen immediately after switching on, after loading a large amount of food, or when the door is not tightly closed. If the indicator is constantly on, check the settings and tightness.
Does the amount of food affect the temperature inside?
Yes, a full refrigerator keeps the temperature more stable, since food acts as cold accumulators. However, if you fill the chamber to capacity and block the ventilation holes, the air circulation will be disrupted and the cooling will be uneven.
