Refrigeration equipment of the Belarusian plant "Atlant" deservedly enjoys the trust of consumers due to its reliability and availability, however, even the highest quality equipment requires proper operation to maintain the freshness of products.
Many owners wonder what exactly the temperature in the freezer should be so that meat does not spoil and vegetables do not lose their taste after defrosting.
In this article we will analyze in detail the temperature conditions, how to adjust them on different models and the reasons for possible deviations from the norm, so that your refrigerator works as efficiently as possible.
Optimal temperature indicators for the freezer
According to international standards and technical documentation of the manufacturer, the ideal temperature for long-term storage of products is in in freezers, the value is considered minus 18 degrees Celsius.
It is at such indicators that biochemical processes in the tissues of products stop, and the proliferation of bacteria and microorganisms becomes impossible, which allows you to store supplies for several months.
Some modern models of refrigerators Atlant equipped with a “super freezing” function, which allows you to briefly reduce the temperature to minus 24 degrees.
- 🧊 Minus 18°C - standard mode for everyday storage of meat and fish products.
- ❄️ Minus 24°C - mode fast freezing for fresh products, turned on for 12-24 hours.
- 🌡️ Minus 6...12°C - short-term storage mode (up to 3 days), typical for older single-chamber models.
It is important to understand that the temperature in different zones of the freezer may vary slightly, especially if the chamber has several compartments or boxes.
The coldest zones are usually located at the back wall and in the upper compartments, where cooled air descends, so for long-term preparation of semi-finished products it is better to use these places.
⚠️ Attention: Long-term storage of products at temperatures above minus 12°C can lead to a loss of their taste and a reduction in shelf life, even if outwardly they look normal.
Classification of freezers and markings
When choosing a refrigerator or studying the instructions for your unit Atlant you may encounter markings in the form of snowflakes, which indicate the class of the freezer and its capabilities.
This classification system is universal for all manufacturers and helps to understand how long products can be stored without losing their properties.
One asterisk (*) means that the chamber is capable of maintaining temperatures down to minus 6 degrees, which is only suitable for storing already frozen products for one week.
Two asterisks (**) indicate the ability to freeze fresh products and store them for up to one month at a temperature of minus 12 degrees.
Three stars (***) is the standard for most modern models Atlant, providing a temperature of minus 18 degrees and storage for up to three months.
Four stars (****) indicate the presence of a quick freezing function and the ability to store supplies for up to a year without loss of quality.
Knowing the class of your freezer will help you correctly plan the purchase of food and not store meat or fish longer than the recommended period.
For example, in a chamber with one star, you should not make strategic stocks of dumplings for the winter, since by summer they can become dry and tasteless.
How to adjust the temperature in different Atlant models
The methods for setting the temperature directly depend on the type of control installed in your refrigerator model - mechanical or electronic.
In models with mechanical control, adjustment is carried out using a rotary regulator, which is usually located inside the refrigerator compartment or on the top panel body.
The scale of such a regulator is often graduated with numbers from 1 to 7 or from Min to Max, where a higher value corresponds to a lower temperature.
For electronic models, adjustment is made through the control panel on the door, where the temperature is displayed on a digital display with an accuracy of a degree.
In some advanced series Atlant with the system No Frost you can independently adjust the climate in the refrigerator and freezer compartments.
☑️ Checking the temperature settings
If you have just installed the refrigerator or defrosted it, do not try to immediately set the maximum cold.
First, let the unit operate in normal mode for several hours so that the compressor and refrigerant reach the operating cycle, and only then make fine adjustments.
Factors influencing the temperature regime
Even with correctly set settings, the actual temperature inside the chamber can fluctuate under the influence of a number of external and internal influences factors.
One of the main enemies of stable cold is frequent opening of the door, especially in the hot season, when warm, humid air enters the chamber.
Loading density also plays an important role: a completely empty freezer loses cold faster when opened, and a too stuffed one prevents air circulation.
- 🚪 The frequency of opening the door - each time heat gets inside, forcing the compressor to work harder.
- 🥩 Number of products - a large volume of frozen goods acts as a cold accumulator, stabilizing the mode.
- 🧊 The presence of an ice crust - a layer of ice on the walls or evaporator impairs heat transfer and increases energy consumption.
In addition, the location of the refrigerator in the room matters: if it is located close to the wall or next to the radiator, its operating efficiency is reduced.
The technical characteristics of the compressor and the amount of refrigerant also determine how quickly the unit Atlant can restore the set temperature after loading warm products.
⚠️ Attention: Loading a large volume of warm food into the freezer can lead to a temporary increase in temperature and melting of the stocks already lying there.
Table of shelf life of products at different temperatures
Understanding the dependence of shelf life on temperature helps to avoid food poisoning and saves the family budget.
The following are indicative data for various categories of products, provided they are pre-frozen at high quality.
| Product type | At -6°C | At -12°C | At -18°C |
|---|---|---|---|
| Meat (beef, pork) | 1 week | 3 months | 12 months |
| Poultry (whole carcass) | 3 weeks | 6 months | 12 months |
| Fatty fish | 2 weeks | 2 months | 6 months |
| Vegetables and fruits | 1 week | 3 months | 12 months |
It is worth noting that fatty fish and poultry have a shorter shelf life even with deep frozen due to fat oxidation.
To maximize quality preservation, it is recommended to use vacuum packaging, which prevents product contact with air and the formation of “freezer burn.”
What is freezer burn?
Freezer burn is a change in the color and texture of the surface of a product (the appearance of whitish spots) due to sublimation of moisture. The product remains safe, but becomes dry and loses its taste.
Diagnostics of temperature problems
If you notice that the food in the freezer Atlant began to deteriorate faster than usual or ice has formed on the walls, this is a signal of a malfunction.
A frequent cause of an increase in temperature is the failure of the thermostat, which stops sending a signal to the compressor to turn on.
Also, the problem may lie in a freon leak, a compressor malfunction, or a clogged capillary tube of the cooling system.
In models with by electronic control, problems may be indicated by flashing indicators or error codes on the display.
For example, a flashing red light often indicates that the temperature in the chamber is above the permissible norm.
Independent repair of complex components, such as a compressor or refrigerant circulation system, requires special equipment and qualifications.
If simple methods such as defrosting and checking the tightness of the seal did not help, it is better to contact an authorized service center.
⚠️ Attention: Attempts to independently repair the cooling system without appropriate experience, they can lead to the final failure of the refrigerator and loss of warranty.
Frequently asked questions (FAQ)
Why is the temperature in the Atlant freezer -15 instead of -18?
A difference of several degrees can be caused by loose door closure, a large number of products loaded at the same time, or indoor heat. If the difference persists for a long time, the seal may need to be replaced or refilled with freon.
Can food be stored at -10 degrees?
Food can only be stored at this temperature for a short time (several days). For long-term storage, this is too high a temperature, bacteria can begin to multiply and vitamins are destroyed.
How to turn on the super-freeze mode on Atlanta?
In models with electronic control, you need to press the button with the image of a snowflake or the inscription "Super Freeze". In mechanical models, the regulator is temporarily moved to the maximum cold position, but not more than a day.
Does the amount of ice affect the temperature?
Yes, a thick layer of ice on the walls and evaporator acts as a heat insulator, interfering with the removal of heat from the chamber. Regular defrosting (for drip systems) is necessary to maintain efficiency.
