Modern refrigerators brand Atlant have long ceased to be bulky units that require weekly defrosting with basins and rags. Many users, when switching to new models, come across the term “drip system”, but do not fully understand the physical essence of the process. Automatic defrosting This is not magic, but a thoughtful engineering algorithm based on a cyclic change in the temperature of the evaporator.
Unlike old models, where a coat of ice grew directly on the back wall inside the chamber, in systems with drip technology this process is hidden from the owner’s eyes. You no longer need to wait until the weekend to unplug the device and wait several hours for the ice to turn into water. Temperature conditions It is regulated electronically or by a mechanical thermostat, which strictly ensures that moisture does not turn into a monolithic layer of ice.
Understanding exactly how your Atlantoperation will allow you to avoid common operating errors and extend the life of the compressor. In this article we will analyze in detail the physics of the process, consider the design features and answer the questions that most often arise among owners of equipment with a system Direct Cool or combined cooling.
Physics of the process: how the evaporator works
The basis of any refrigeration system is evaporator, which in models Atlant with drip defrosting is located behind the rear panel of the main compartment. When the compressor turns on, the refrigerant circulates through the tubes, cooling the surface of the evaporator to subzero temperatures. At this moment, the moisture contained in the air inside the chamber begins to condense on the coldest surface - the back wall.
You can notice how the first droplets appear on the inner panel, which gradually turn into frost. This is a normal operating process and not a sign of a breakdown. Evaporator temperature falls below the freezing point of water, so ice begins to grow. However, the key difference from old systems is that this layer of ice does not have time to become critically thick due to cyclical operation.
As soon as the temperature you set inside the chamber is reached, the thermostat sends a signal to turn off the compressor. At this point the defrost phase begins. The remaining heat from the products and natural heat exchange with the environment begin to heat the back wall. The ice crust melts, turning into water, which flows into a special groove.
⚠️ Attention: If you notice that the ice coat is growing unevenly or only in one corner, this may indicate a violation of the tightness of the door seal or displacement of the housing relative to the wall.
Water through the channel the outlet flows into a container located above the compressor at the bottom of the unit. There it safely evaporates under the influence of heat from a running motor. Thus, cooling cycle is closed, and moisture is removed from the system without your direct participation.
Differences between a drip system and No Frost
Users often confuse the concepts, believing that the absence of visible ice means the presence of a system No Frost. However, in refrigerators Atlant these technologies can be combined or exist separately. The drip system (or Direct Cool) assumes that in the refrigerator compartment moisture still condenses on the wall, while in No Frost air circulation is forced and dehumidified.
In models with full No Frost the evaporator is completely hidden and you never see ice on the back wall of the chamber. The air is forced by a fan through a hidden heat exchanger, where it is cooled and dried. In drip models Atlant the rear wall of the refrigeration compartment will always be slightly damp or covered with a thin layer of frost when the compressor is operating.
Let's compare the main characteristics of these approaches for a better understanding:
| Parameter | Drip system (Direct Cool) | No Frost system |
|---|---|---|
| Presence of ice | Forms a thin layer on the wall | Absent from the chamber |
| Humidity | High, food dries more slowly | Low, food can get airy |
| Noise | Quiet operation (no fan) | Noise is heard fan |
| Energy consumption | Lower | Higher due to the fan and heating elements |
Many choose Atlant with a drip system in the refrigerator compartment, as it provides a more gentle mode for vegetables and fruits. Humidity in such chambers it is higher, which prevents the rapid withering of products. At the same time, the freezer in such models is often equipped with a No Frostsystem, which creates an ideal balance.
Why does water sometimes appear on the shelves in a drip system?
This happens if the drain hole is clogged. The ice plug prevents the water from leaving, and it overflows over the edge of the gutter, falling on the food.
Design features of Atlant refrigerators
Engineers Atlant implemented a number of specific solutions to optimize the defrosting process. First of all, it is worth noting the design of the rear panel. It is made of plastic with a special profile that directs air flow and promotes uniform distribution of cold. This reduces the likelihood of the formation of local zones with excessive freezing.
The drain channel in these models is often equipped with a special plug or valve that prevents warm air from the outside from entering the thermal insulation. This is an important detail that affects Energy efficient the entire system. If this element is damaged or displaced, the compressor will work longer, trying to compensate for heat gain.
- 🧊 Rear wall Made from a material with low thermal conductivity, which speeds up the defrost process when the compressor stops.
- 💧 The drain chute has an increased slope so that the water does not stagnate and does not freeze again when turned on.
- ❄️ The temperature regulator is configured so that the pauses between turns on are sufficient for the condensate to completely drain.
In some modern series Atlant multi-threaded cooling is used, even with a drip system. This means that cold air is distributed not only from the rear wall, but also through additional channels. This approach allows you to quickly restore temperature regime after opening the door, minimizing the operating time of the compressor.
⚠️ Attention: The design of the drain hole may vary depending on the year of manufacture of the model. Older versions may require periodic cleaning with a brush, while new ones have a self-cleaning system installed.
Is the formation of ice on the wall normal?
This is the most common question that arises among owners of new refrigerators. The short answer is yes, this is absolutely normal for a drip system. Moreover, if there is absolutely no frost or drops on the back wall, this may indicate a malfunction of the cooling system or a freon leak. Atlant There is absolutely no frost or drops, this may indicate a malfunction of the cooling system or a freon leak.
The process looks cyclical: first the wall is cooled and covered with a “fluff” of frost. Then the compressor turns off, the frost melts, turning into large drops that run down. Visually you can observe how ice cover it appears and then disappears. This is the working phase of drip defrosting.
You should only worry if:
- ❄️ The layer of ice becomes thick (more than 3-5 mm) and does not melt even after a long pause.
- 💧 Water accumulates at the bottom of the refrigerator or under the vegetable drawers.
- 🌡️ Products near the back wall freeze to it tightly.
If ice grows evenly over the entire surface of the rear panel, it means the system is working properly. The only problem is local freezing or the formation of ice stalactites that prevent the boxes from closing. In such cases, diagnostics thermostat or checking the tightness of the circuit.
Operating rules and typical errors
Even the most reliable equipment Atlant will fail ahead of time if the basic operating rules are violated. The drip system is sensitive to thermal loads. Frequent and prolonged opening of doors leads to an intense influx of moist air, which instantly turns into ice on the evaporator.
One of the common mistakes is installing hot or warm products. This causes a sharp jump in humidity and temperature, forcing the compressor to wear out. Temperature balance is disrupted, and the defrosting system simply does not have time to cope with the volume of melting ice.
It is also important to monitor the position of the refrigerator. If the unit is tilted backwards or skewed to one side, gravity will not be able to perform its function - the water will not flow into the drain hole, but will spread along the bottom of the chamber. Use a building level to check the horizon.
☑️ Checking correct installation
Do not forget about hygiene. Although the system is called self-service, it cannot process crumbs, dirt and food debris. Once in the drain channel, organic matter sours and clogs the drain, which leads to the appearance of an unpleasant odor and puddles inside the chamber.
Maintenance and troubleshooting
Despite automation, your Atlanta ll still require minimal maintenance. Approximately once every 6-12 months, it is recommended to carry out preventive cleaning of the drain hole. This is a simple procedure that will take no more than 10 minutes, but will save you from many problems.
To clean the canal, you can use a special soft brush, which is often included, or a regular cotton swab. You need to act carefully so as not to pierce the tube and damage the thermal insulation. After mechanical cleaning, you can rinse the channel with warm water from a syringe.
If you are faced with the fact that the refrigerator has stopped freezing or ice freezing has become excessive, check the following:
- 🔌 The tightness of the door and the condition of the rubber seal.
- 🌡️ Thermostat settings (perhaps the maximum power mode is set).
- ❄️ The presence of an ice plug in the outlet of the gutter.
⚠️ Attention: Never use sharp metal objects (knives, screwdrivers) to chip ice. Damage to the evaporator will lead to an immediate release of freon and expensive repairs.
If simple measures do not help, and the ice coat grows again and again, it is likely that the defrost sensor has failed. In such situations, it is better to contact an authorized service center thermostat or defrost sensor. In such situations, it is better to contact an authorized service center Atlant for professional diagnostics.
Frequently asked questions (FAQ)
Why does water flow from the refrigerator onto the floor?
Most likely, the drain hole behind the back panel is clogged. Ice or dirt prevents water from escaping into the container above the compressor, and it overflows over the edge of the chute into the chamber and then onto the floor. Also, the reason may be the misalignment of the refrigerator.
How often do you need to defrost the Atlant refrigerator with a drip system?
The manufacturer recommends completely defrosting and washing the refrigerator at least once a year. This is necessary for hygienic processing and checking the condition of the seals, even if there is no visible ice inside.
Is it possible to speed up the defrosting process with a hair dryer?
It is strictly not recommended to direct hot air flows from the hair dryer to the plastic inner panel. The plastic can be deformed, and a sudden temperature change can damage the evaporator hidden behind the wall. Let the ice melt naturally.
Why is the back wall covered with ice even though the refrigerator is new?
For a drip system, this is normal operating mode. A thin layer of frost or “puff” indicates that the evaporator is working correctly. The ice should disappear on its own in pauses between turning on the compressor.
What to do if food freezes to the back wall?
Move the food away from the wall. In the area of direct contact with the evaporator, the temperature is always lower than the average in the chamber. Store freeze-sensitive products (greens, dairy products) on the door or in the front rows of shelves.
