When choosing household appliances for the kitchen, one of the key parameters is the number of compressors, and the question of how many are installed in the refrigerator Atlantworries many buyers. The Belarusian manufacturer has long established itself in the market, offering solutions with both one and two motors, which directly affects the functionality and price of the device. Understanding this difference helps to avoid overpaying for unnecessary functions or, conversely, save where possible without loss of quality.
The modern market offers a wide range of models, where technical characteristics can differ significantly even within the same series. Compressor is the heart of the unit, and its quantity determines whether the equipment can work in two cooling circuits independently of each other friend. In this article, we will analyze the design features in detail so that you can make an informed choice.
It is important to note that the number of motors is not the only indicator of efficiency, but it sets the base level of the system's capabilities No Frost or drip defrosting. Let's figure out exactly how it works and what is best for your family.
Main types of Atlant compressor systems
Belarusian brand refrigerators are divided into two main categories based on the number of engines: single-compressor and double-compressor models. In the first case, one powerful motor serves both compartments at once - the refrigerator and freezer compartments, switching between them alternately. In the second option, each circuit has its own independent source of cold, which ensures a more stable temperature regime.
Single-compressor units are often equipped with a system Single Coolingwhere cold air circulates between the chambers through a common channel. This is an economical solution that is found in budget and mid-priced series. Dual-compressor models, in turn, allow you to set different temperature conditions without the risk of freezing of products in the upper compartment.
Independent cooling in dual-engine systems provides a number of advantages, especially for those who purchase products for future use. If the freezer runs out of freon or one of the motors fails, the refrigerator compartment will continue to operate as normal, keeping vegetables and drinks fresh.
How to determine the number of compressors visually
Often buyers wonder how to find out how many motors are installed in the selected model without looking at the technical data sheet. The easiest way is to look at the back of the device. If you see one black barrel-shaped element, most likely you have a single-circuit system. The presence of two such elements clearly indicates a two-compressor design.
Information can also be found on the information sticker, which is usually located inside the refrigerator compartment on the side wall or on the door. The technical specifications section indicates the power consumption and type of refrigerant, which indirectly confirms the complexity of the system. Models with index KHT or KHMT often have two motors, but it is better to double-check the specific modification.
⚠️ Attention: Do not try to remove the back panel or disassemble the compressor compartment yourself if the device is under warranty. This may lead to loss of warranty service.
Another sign is the presence of separate temperature controllers for each chamber. If there are two independent switches (thermostats) on the control panel or inside the housing, this is a sure sign of a dual-circuit system. In single-circuit models, adjustment is often carried out by one common mechanical lever.
Advantages of two-compressor refrigerators
The main advantage of having two motors is the complete autonomy of the circuits. You can defrost the refrigerator compartment without touching the stock in the freezer, and vice versa. This is especially convenient for long trips or the need to defrost one of the compartments without losing food in the other.
In addition, two-compressor models Atlant quickly reach the set temperature after loading with a large amount of warm products. Each motor operates only at its own volume, which reduces the overall load on the system and extends the service life of the unit. Energy consumption in such models may be even lower, since the motors turn on less often and operate in short cycles.
List of key advantages of a dual-motor system:
- 🧊 Complete independence of temperature conditions in different chambers
- 🔇 Reduction noise level due to load distribution
- ⚡ Energy savings when chambers are partially loaded
- 🛡️ Increased reliability: the output of one motor does not stop the entire system
It is worth noting that systems No Frost in two-compressor models work more efficiently, since Each compartment is blown independently. This prevents mixing of odors, which is critical for storing fish, meat and ready meals in one device.
Features of operation of single-circuit models
Single-compressor refrigerators Atlant remain popular due to their affordable price and simplicity of design. In such systems, the refrigerant flows through a single circuit, first cooling the freezer compartment and then passing into the refrigerator compartment. The cold flow is controlled using an electromagnetic valve.
The main feature of such models is the inability to completely independently regulate the temperature. If you set your freezer to super freeze, the refrigerator compartment will also become colder, which may cause vegetables to freeze at the back. However, modern control systems have learned to minimize this effect.
Despite the limitations, such refrigerators cope well with everyday tasks in small families. They take up less space, weigh less and are easier to repair. Spare parts for single-circuit systems are always available, and the cost of their replacement is lower.
Comparative table of system characteristics:
| Characteristics | One compressor | Two compressors |
|---|---|---|
| Independence contours | No | Yes |
| Noise level | Average | Low |
| Energy consumption | Standard | Economical |
| Repair cost | Low | High |
Influence of the number of motors on safety products
The number of compressors directly affects the microclimate inside the chambers. In dual-circuit systems, there is no air circulation between the freezer and refrigerator, which prevents drying the products. The moisture remains in the products, and is not frozen out by a powerful stream from the freezer compartment, as happens in cheap single-circuit models.
Stable humidity is critical for storing vegetables, fruits and herbs. Two-compressor Atlanta with system Multi Flow or analogues provide gentle cooling without drafts. This allows you to preserve vitamins and freshness of food for several days longer.
The myth about the smell
There is an opinion that odors never mix in two-compressor refrigerators. This is only partly true: the tightness of the chambers is high, but when the door is opened, odors can still enter the general volume of the kitchen and then into another chamber, although to a lesser extent.
In single-circuit models, the risk of food freezing at the back wall is higher. It is important to distribute food correctly, without placing cold-sensitive items close to the back panel. Adjusting the cold air damper helps, but does not solve the problem completely.
⚠️ Attention: In single-circuit models, it is not recommended to store open products with a strong smell (fish, smoked meats) without sealed packaging, as the smell will quickly spread throughout the entire volume.
Energy consumption and efficiency
The issue of saving energy often becomes decisive when purchasing. Many people mistakenly believe that one motor consumes less energy than two. However, in reality, two-compressor models are often more economical. The reason lies in the operating mode: each motor turns on only when the temperature in its chamber rises above normal.
In a single-circuit system, a powerful motor is forced to work harder to cool two volumes at once, especially after frequently opening the door or loading warm products. The dual-motor system works more “intelligently,” spending resources only on the required circuit.
Energy consumption class A++ or A+ is found in both types of models, but achieving high performance in dual-compressor units is easier thanks to modern inverter technology. Inverter compressors Atlant smoothly regulate power, avoiding peak loads on the network.
☑️ Check before purchase
Maintainability and service life
From a reliability point of view, the presence of two motors distributes the load, which theoretically increases the overall service life of the device. If one compressor fails after 10 years, the second will continue to work, and you will not have to urgently replace the entire refrigerator. Replacing one motor in such a system is a standard procedure for service centers.
However, it is worth considering that in two-compressor models there are more components that could potentially fail (two starting relays, two thermostats, more pipes and connections). Service center statistics show that Atlant compressors last an average of 10-15 years, regardless of their quantity, subject to proper operation.
Single-circuit models are characterized by the ease of replacing the compressor, but its failure means a complete stop in the operation of the refrigerator. It is important to keep the condenser at the back of the device clean and provide good ventilation to extend the life of the motor.
Timely maintenance and proper installation will extend the life of any equipment. Do not place the refrigerator close to the wall and regularly check the door seals for leaks.
Frequently asked questions (FAQ)
Is it possible to turn off the freezer separately in an Atlant single-circuit refrigerator?
In most single-circuit models, turn it off completely the freezer is not possible, since the refrigerant passes through both circuits. However, many modern models have a “Vacation” function or the ability to adjust the freezer temperature to minimum values, but there is no complete independence, as in two-compressor models.
Is it true that a two-compressor refrigerator is louder?
On the contrary, two-compressor models are often quieter. Because the load is shared, each motor works less hard and is less likely to run at full power. In addition, they do not create such a strong buzz as one powerful motor operating in a stronger mode.
How to find out the exact number of compressors by model?
Look at the model markings. Often the name or technical data sheet indicates the number of circuits. You can also find the model on the Internet on the manufacturer’s official website or in online stores, where the characteristics always indicate: “Number of compressors: 1 or 2.”
Is it worth overpaying for two compressors in a small refrigerator?
If the budget allows, then yes, this will add comfort. But for small-sized refrigerators (up to 150 cm in height), one high-quality compressor is often used, and the difference in performance will not be as noticeable as in large units with a volume of 300+ liters.
