Owners of modern household appliances often come across abbreviations and names of functions that are not always clear at first glance. One of such technologies is the Natur Cool (NaturalCool) system in refrigerators of the German brand Bosch. Many users see this inscription on the control panel or in the instructions, but do not fully understand the principle of its operation and the impact on the safety of products.
In fact, we are talking about an advanced air circulation system, which is radically different from the usual static freezing. NaturalCool created in order to most accurately imitate natural storage conditions, preventing food from drying out and mixing odors. In this article we will analyze in detail the structure of the system, its differences from the classic one NoFrost and operating rules.
Understanding the operation of this mode allows you not only to extend the shelf life of products, but also to significantly save on electricity. The key feature of the system is the distribution cooled air through special channels in the rear wall, which eliminates the formation of an ice crust. Let's look at the technical nuances in more detail.
The principle of operation of the NaturalCool system
Technology NaturalCool is based on the principle of multi-flow cooling. Unlike older models, where cold air fell from top to bottom, special fans and distribution channels are used here. They direct air flows to each level of the refrigeration chamber separately, ensuring uniform temperature throughout the entire volume.
It is important to note that the system Bosch constantly monitors the temperature conditions using sensors. If you open the door, sensors detect a temperature jump and the compressor temporarily increases power. This allows you to quickly return the parameters to the set values without overloading the motor.
Air circulation occurs in such a way as not to create direct drafts that could damage delicate products such as greens or baked goods. Humidity the chamber is maintained at an optimal level due to the fact that the air is not dried directly by the freezing element, but passes through the buffer zones.
⚠️ Attention: Do not block the ventilation holes on the back wall of the refrigerator with food. Blocking the air flow will disrupt the operation of the system NaturalCool and lead to uneven cooling.
The efficiency of operation depends on the correct placement of weights inside the chamber. Packing food tightly against the back wall can create “heat pockets” where temperatures will be higher than normal. The system NaturalCool requires free space for the circulation of gas flows.
Differences from the classic NoFrost system
Frequent users are confused Natur Cool with the conventional system NoFrost, believing that they are one and the same. However, there is a significant technical difference between them, specifically regarding the method of supplying cold and controlling humidity. Understanding these differences will help you choose the right storage mode for different types of products.
In standard NoFrost air is usually supplied from one or two main channels, which can create zones with different temperatures. NaturalCool uses a distributed network of channels, which makes the temperature field more uniform. This is especially important for storing dairy products and meat.
- 🌡️ Uniformity: In the system Bosch the temperature difference between shelves is minimal, unlike classic models.
- 💧 Humidity: NaturalCool better retains natural humidity, preventing weathering products.
- 🔇 Noise: Modern fans are quieter due to optimized aerodynamics of the blades.
- ❄️ Frost: Both systems prevent ice formation, but the moisture removal mechanism is structurally different.
Another difference is the speed of temperature recovery after loading warm products. Algorithms NaturalCool react more flexibly, distributing cold air exactly to the area where heating occurred. This reduces the overall load on the compressor in the long run.
Advantages of technology for food storage
Using the mode Natur Cool gives tangible advantages in everyday use. First of all, this concerns the preservation of the taste and appearance of food. Due to the absence of direct flows of dry cold air, vegetables and fruits remain elastic much longer.
Meat and fish products in such conditions are not covered with an unpleasant crust, which often forms during normal freezing. Freshness is preserved due to a stable temperature background, which does not allow bacteria to actively multiply in the “warm” areas of the refrigerator.
| Product type | NaturalCool effect | Comparison with normal mode |
|---|---|---|
| Greens and herbs | Retain elasticity for up to 5 days | Wither and dry quickly |
| Dairy products | Stable structure, no delamination | A film may appear |
| Ready meals | Do not absorb foreign odors | High risk of mixing flavors |
| Fruits | Slow ripening, no rot | Uneven cooling |
We should also mention hygiene. Air circulation in the system Bosch often passes through special filters (depending on the model) that trap bacteria and unpleasant odors. This makes storing open food safer for health.
Adjusting temperature conditions
For efficient operation of the system Natur Cool you need to set the temperature correctly. The control panel of refrigerators Bosch is usually equipped with an electronic display or mechanical controls with a digital display. The optimal value for the refrigerator compartment is considered to be a range from +2 to +4 degrees Celsius.
To change the settings, you usually need to press the button Temp or Mode and hold it for several seconds until the flashing indicators appear. Then, using the + and - buttons, the desired value is set. In some models with touch control, you just need to touch the screen.
If you have a model with the function SuperCool (Super Cooling), it can be activated immediately after loading a large number of products. The mode operates for about 6 hours, intensively cooling the chamber, and then automatically turns off, returning control to the system NaturalCool.
⚠️ Attention: Prolonged use of the super cooling mode unnecessarily can lead to freezing of products located at the back wall. Use it only when fully loaded with warm food.
Do not forget that the temperature setting depends on the refrigerator load and the ambient temperature. In the summer, when the kitchen is hot, it makes sense to set the value 1 degree lower to compensate for heat gain.
☑️ Setting the ideal mode
Possible malfunctions and their elimination
Despite the reliability of the equipment Bosch, the system Natur Cool may encounter problems. The most common cause of failures is contamination of the ventilation ducts or failure of the temperature sensor. If you notice that food has begun to deteriorate faster or condensation has appeared on the walls, this is a signal of a malfunction.
The first thing to do if you suspect a breakdown is to carry out a visual inspection and defrost (if the model requires it, although NoFrost usually it does not need it). Sometimes the problem is solved by simply cleaning the drainage hole through which moisture is removed.
- 🔊 Extraordinary noise: May indicate a fan malfunction or a foreign object getting into the blades.
- 🌡️ Unstable temperature: Often caused by a broken thermostat or sensor NaturalCool.
- 💨 Lack of circulation: Check whether the air ducts are clogged with ice or food.
- ❄️ Ice in the chamber: Indicates that the door is not sealed or the defrost is malfunctioning.
If simple diagnostic methods do not help, you need to contact a service center. Self-repair of complex electronics or a compressor group may lead to loss of warranty. Diagnostics with professional equipment will take less time than experiments at home.
What to do if the refrigerator hums after installation?
A new refrigerator may hum the first hours of work are normal. Also make sure that it stands level and does not touch walls or furniture, which increases vibration.
Rules for caring for the cooling system
For the technology Natur Cool to serve for a long time and efficiently, it needs to be looked after. Regular cleaning of the internal surfaces prevents grease and food particles from clogging the filters and channels. Use mild detergents that do not contain abrasives and chlorine to avoid damaging the plastic elements.
Pay special attention to the area around the ventilation holes. Periodically (every 3-4 months) it is recommended to carefully vacuum the back wall inside the chamber, removing any dust that may have gotten there. This will improve heat transfer and reduce energy consumption.
It is also important to monitor the condition of the rubber seals on the doors. If they do not fit tightly, the system NaturalCool will work with overload, trying to compensate for the constant flow of warm air. The check can be carried out using a sheet of paper sandwiched between the door and the body.
⚠️ Attention: Never use sharp objects or steam cleaners to clean the inside of the refrigerator. This can damage the sensors and plastic air ducts of the system. Compliance with these simple operating rules will allow your refrigerator to keep food fresh for many years. Technology NaturalCool.
Following these simple operating rules will allow your refrigerator to Bosch keep food fresh for many years. Technology Natur Cool is an investment in the quality of nutrition and health of your family.
Is it possible to disable the NaturalCool system?
Completely disable air circulation in modern models Bosch It is impossible, since this is the basic principle of operation of the refrigerator. However, you can change the temperature mode or activate the “Holiday” mode, which puts the equipment into an economical operating mode with minimal cooling.
Why is the wind blowing in the refrigerator compartment?
A noticeable air flow is the normal operation of the system. NaturalCool. The fan drives cold masses through the chamber. If the flow is too strong and dries out the food, check to see if the air ducts are blocked and try lowering the fan speed (if your model has such a setting). How often should you defrost a NaturalCool refrigerator? defrosting. However, manufacturers recommend that once a year (or if it is very dirty) completely turn off the refrigerator, wash it and let it dry for several hours for hygiene.
How often should I defrost my NaturalCool refrigerator?
Systems NoFrost And NaturalCool do not require regular defrosting. However, manufacturers recommend that once a year (or if it is very dirty) you completely turn off the refrigerator, wash it and let it dry for several hours for hygiene.
Does NaturalCool affect energy consumption?
Yes, it does. Thanks to the even distribution of cold and smart sensors, the compressor turns on less often and works more efficiently. In the long run, this can reduce energy consumption compared to older models without smart controls.
