Two-chamber refrigerators Atlant have long established themselves as reliable assistants in the kitchen, but not all users fully understand how exactly their freezer compartment works. Not only the safety of food, but also the energy efficiency of the device, as well as its durability, depend on the correct operation of the freezer. In this article we will analyze in detail what technologies are used in Atlant freezershow to regulate the temperature, what modes are available in different models and what to pay attention to during operation.
Features of two-chamber refrigerators Atlant —separate cooling systems for the refrigerator and freezer compartments (in models with No Frost) or a single circuit with forced circulation (in classic versions). This affects how the refrigerator freezes, how long it takes to freeze, and how often it needs to be defrosted. We will also look at typical “symptoms” of malfunctions associated with the operation of the freezer and give practical advice on how to eliminate them.
Design of the freezer compartment in Atlant refrigerators: key elements
Freezer compartment in two-chamber models Atlant consists of several main components, each of which is responsible for a specific function. Understanding their operation will help you operate the equipment correctly and identify problems in a timely manner.
Main elements:
- 🔹 The evaporator —a metal radiator, where the refrigerant (freon) passes from a liquid to a gaseous state, actively absorbing heat. In models with No Frost the evaporator is hidden behind the back panel, in classic models it is located openly.
- 🔹 Compressor is the “heart” of the refrigerator, which pumps refrigerant through the system. In Atlant most often inverter or linear compressors are installed (for example, Danfoss or Secop).
- 🔹 Thermostat or electronic control unit - regulates the temperature by turning the compressor on/off. Modern models use electronic control with sensors.
- 🔹 Fan (in systems No Frost) - ensures the circulation of cold air, preventing the formation of frost.
- 🔹 Door seal - is responsible for tightness chambers. A damaged seal leads to loss of cold and increased load on the compressor.
In models with No Frost (for example Atlant XM 6025-031), the freezer is equipped with an automatic defrosting system: moisture condenses on evaporator, and then taken to a special tray where it evaporates. In classic refrigerators (for example Atlant MHM 1705), defrosting has to be done manually 1-2 times a year.
Operation principle freezer: how freezing occurs
The cooling process in the freezer Atlant is based on the cyclic operation of the refrigerant (freon) and the compressor Let's look step by step at how this happens:
- Refrigerant compression: The compressor sucks. gaseous freon from the evaporator and compresses it, increasing the temperature and pressure.
- Condensation: Hot freon enters the condenser (grid on the back wall of the refrigerator), where it cools and turns into a liquid state, releasing heat to the environment.
- Expansion: Liquid freon passes through a capillary tube (or expansion valve), where its pressure drops sharply.
- Evaporation: The refrigerant enters the evaporator of the freezer, where it boils, absorbing heat from the interior. The temperature in the chamber drops.
- Repeat the cycle: Freon gas again enters the compressor, and the process repeats.
In refrigerators with No Frost fan distributes cold air evenly throughout the chamber, preventing the formation of frost. In classic models, cold spreads naturally, so ice can accumulate in the freezer, especially when the door is opened frequently.
Important: In two-chamber refrigerators Atlant the freezer and refrigerator compartments can operate either from one compressor (with separate control) or from two separate ones. (in premium models). This affects energy consumption and temperature control capabilities.
Freezer operating modes: what are they and how to choose
Modern two-chamber refrigerators Atlant are equipped with several operating modes for the freezer compartment. Their choice depends on the number of products, frequency of use and external conditions (for example, room temperature). data-i="110">Atlant
| Mode | Temperature, °C | Purpose | Energy consumption |
|---|---|---|---|
| Super freezing | from -24 to -30 | Quick freezing of large volumes of food (up to 4-5 kg at a time). Turns on for 24-48 hours. | Increased |
| Optimal | –18 | Standard mode for long-term storage of food. | Normal |
| Economic | –16 | Suitable for a small amount of food or when the freezer is rarely used. | Reduced |
| Vacation | –14 | Minimum energy consumption during long absence (for example, on a business trip). | Minimum |
In most models Atlant switching between modes is carried out using a mechanical thermostat or an electronic panel. For example, in Atlant XM 4426-080 modes are selected by buttons on the display, and in Atlant MHM 2835-80 by a rotary switch.
How to use the modes correctly:
- 🍗 Super freezing turn on 2-3 hours before loading the products. After freezing, return to the optimal mode.
- ❄️ In economy mode do not store meat, fish or ice cream for longer than 1-2 weeks - partial defrosting is possible.
- 🏝️ Mode "Vacation" is not suitable for storing perishable foods Before leaving, defrost and wash. camera.
Optimal temperature in the freezer: norms and settings
According to standards, the ideal temperature for long-term storage of products in the freezer is –18°C. However, depending on the load and type of products, this indicator can be adjusted. Let's consider the recommendations for different cases:
Recommended temperatures:
- 🥩 Meat and fish: –18°C (long-term storage up to 6–12 months).
- 🍦 Ice cream and semi-finished products: –18°C (preserves texture and taste).
- 🥬 Vegetables and fruits: –16°C (prevents softening).
- 🍞 Bread and pastries: –14°C (enough for storage for 1–2 months).
In refrigerators Atlant temperature is regulated:
- 🔘 Mechanical thermostat: rotary regulator with divisions from 1 to 7 (where 1 is the highest temperature, 7 is the lowest).
- 📱 Electronic panel: precise temperature setting in 1°C steps (in models with a display, for example, Atlant XM 6321-000).
In models with one compressor, changing the temperature in the freezer can affect the refrigeration compartment. For example, if you set the freezer to -24°C, the temperature in the main compartment may drop to +2°C, which will lead to freezing of food.

Typical problems with the freezer and how to eliminate them
Even reliable refrigerators Atlant can malfunction freezer compartment. Let's look at the most common malfunctions and their possible causes:
| Problem | Possible causes | Solution |
|---|---|---|
| The freezer does not freeze, but the refrigeration compartment is working | Clogged capillary tube, freon leak, thermostat malfunction | Call a technician to diagnose and refill freon |
| Formation of a thick layer of ice | System malfunction No Frost, damaged seal, frequent door opening | Defrost the refrigerator, check the seal, replace the defrost heating element if necessary |
| Continuous operation of the compressor without shutting down | High room temperature, freezer overload, malfunction thermostat | Reduce the load, check the settings, replace the thermostat |
| Noise or vibration during operation | Incorrect installation, compressor wear, foreign objects getting into the fan | Level the refrigerator, clean the fan, if there is strong vibration - replace compressor shock absorbers |
If the freezer has stopped freezing, first check:
- Is the refrigerator connected to the network (maybe the machine has tripped or the socket is faulty).
- Is the mode turned on "Vacation" or "Eco"at which the temperature in the freezer increases.
- Is the chamber overloaded with products (air circulation should be free).
What to do if the freezer freezes too much?
If the food in the freezer is covered with a thick layer of frost or freezes (for example, vegetables become brittle), the reason may be:
- Faulty thermostat (replaced by a technician).
- Clogged capillary tube (cleaning or replacement is required).
- Incorrect temperature setting (check the settings).
As a temporary measure, you can move the regulator one notch towards increasing the temperature (for example, from 5 to 4).
Warranty warning:
⚠️ Attention: Self-repair of refrigerators Atlantthat are under warranty will invalidate it. Before any manipulations with internal components (filling freon, replacing a compressor), contact an authorized service center for a list of centers.
How to properly defrost the Atlant freezer
Even if your refrigerator is equipped with a system No Frost, periodic defrosting and cleaning of the freezer is necessary to maintain hygiene and operational efficiency For models with manual defrosting (for example, Atlant MHM 1703) This is a mandatory procedure 1-2 times a year.
Step-by-step instructions:
- Unplug the refrigerator and remove all products For temporary storage, use a cooler bag or a bowl. ice.
- Place containers with hot water (not boiling water!) in the chamber or use a hair dryer in cold air mode to speed up defrosting. Do not scrape the ice with a knife or metal objects this will damage the evaporator.
- After complete thawing, rinse the chamber with a warm solution of soda (2 tablespoons per 1 liter of water) or a special detergent for refrigerators.
- Wipe all surfaces dry and leave the door open for 1-2 hours to ventilate.
- Connect the refrigerator to the network and wait until it reaches operating temperature before loading food.
Tips for speeding up defrosting:
- ⏳ Place a bowl of hot water on a shelf - the steam will speed up the melting of the ice.
- 🧊 Use a plastic scraper or spatula to remove melted ice.
- 🚫 Do not use salt or vinegar for cleaning - they can damage the plastic and rubber seals.
⚠️ Attention: If after defrosting the refrigerator does not turn on or the freezer does not cool, do not try to reconnect it to the network repeatedly. This may indicate a malfunction of the start relay or compressor.
Operating Tips: How to Extend the Life of Your Freezer
Following simple rules will help avoid breakdowns and ensure the long service of your refrigerator AtlantHere are the key recommendations:
Organization space:
- 📦 Distribute food evenly without blocking the ventilation holes (in models with No Frost).
- 🥶 Do not place hot or warm food in the freezer - this leads to the formation of condensation and ice.
- 🏷️ Use airtight containers or bags for storage to avoid weathering and cross-odor.
Care of equipment:
- 🧽 Once a month, wipe the door seal with a weak solution of vinegar (1:1 with water) to prevent mold.
- 🔌 Regularly clean the condenser (grid on the back wall) from dust using a vacuum cleaner or brush.
- 🌡️ Monitor the room temperature: the optimal range for the refrigerator to operate is from +16°C to +32°C.
Energy saving:
- 💡 Do not place the refrigerator next to the stove, battery or under direct sunlight.
- 🔌 Turn off the mode "Super Freeze" after use - it increases energy consumption by 25–30%.
- 📏 Optimal distance from the wall to back wall of the refrigerator - 5–10 cm for free air circulation.
FAQ: Frequently asked questions about the operation of the Atlant freezer
Why does the freezer work without stopping?
Continuous operation of the compressor can be caused by:
- High room temperature (for example, in summer).
- A door that is not tightly closed or a damaged seal.
- Freon leak or clogged capillary system.
- Faulty thermostat or temperature sensor.
Check the seal, temperature settings and rear wall ventilation. If the problem persists, call a technician.
How often should you defrost the refrigerator? "Atlant" with No Frost?
In models with No Frost defrosting is required less often - about once a year. However, this depends on the operating conditions:
- If the door is opened frequently or there is high humidity in the room, defrost every 6 months.
- If it appears in the freezer ice or an unpleasant odor, carry out unscheduled cleaning.
The system No Frost prevents icing, but does not eliminate the need for hygienic cleaning.
Is it possible to store food in the Atlant freezer during a power outage?
If there is a power outage, the freezer compartment remains cold for:
- up to 12–18 hoursif the door does not open and the chamber is filled with food (they act as cold accumulators).
- up to 4–6 hoursif the compartment is almost empty.
To extend the cold storage time:
- Do not open the door unless necessary.
- Wrap the refrigerator a blanket or thick cloth.
- Use cold accumulators (if they have been frozen in advance).
Why does a lot of ice form in the freezer, despite No Frost?
Causes of icing in systems No Frost:
- Malfunction Defrost heating element —it must be turned on periodically to remove frost from the evaporator.
- Failure defrost timer or temperature sensor.
- Clogging drainage hole, due to which moisture does not drain into pan.
- Frequent or prolonged opening of the door, leading to increased humidity.
To eliminate the problem, diagnostics and replacement of faulty parts are required.
Which Atlant model is best suited for a large family?
For a family of 4-5 people, two-chamber models are recommended with:
- Freezer volume from 100 liters (for example, Atlant XM 6026-031 - 120 l).
- System No Frost (no need for manual defrosting).
- Function "Super Freeze" for quick processing of large volumes of products.
- Energy efficiency class A+ or higher.
Also pay attention to models with freshness zones (for example, Atlant XM 6321-000), where you can store vegetables and fruits without freezing.
