Modern brand refrigerators Liebherr are famous for their technology and thoughtful functionality, which often goes beyond simply storing food. One of the key modes that is of interest to owners is the Cool Plusfunction. Many users, when encountering this designation on the control panel for the first time, wonder about its purpose and differences from standard cooling.
In this article we will analyze in detail what it is Cool Plus, how exactly this mode affects the operation of the compressor and the temperature in the chamber. Understanding the principles of operation of this option will allow you to make the most of the capabilities of your equipment and extend the shelf life of food.
Unlike basic models, where the temperature is maintained at the same level, Liebherr implements intelligent cold control algorithms. Mode Cool Plus is not just a marketing name, but a real engineering feature that allows you to quickly reduce the temperature in a certain compartment without damaging the rest of the contents of the refrigerator.
The principle of operation of the Cool Plus system
Function Cool Plus in refrigerators Liebherr is an enhanced cooling mode that is activated by the user manually or automatically (depending on the model and settings). The main task of this mode is to create a temporary decrease in temperature in the main refrigeration chamber or in the freshness zone.
When you activate Cool Plus, the control system receives a signal to increase the compressor power. In standard mode, the refrigerator maintains the set temperature, periodically turning on and off. In the enhanced cooling mode Liebherr ignores standard pauses and works continuously until target values are reached.
It is important to understand that Cool Plus is not an analogue of the “SuperFrost” mode, which is intended exclusively for the freezer. Here we are talking specifically about the refrigerator compartment. The system directs the main flow of cold air to the upper and middle parts of the chamber, where ready-made dishes and perishable foods are usually stored.
⚠️ Attention: Long-term operation in the mode Cool Plus can lead to freezing of vegetables and fruits stored in close proximity to the cold air outlet. It is not recommended to keep this mode turned on constantly.
Technically, the process is as follows: temperature sensors record the current state, and the electronic module Liebherr gives a command to change the operation of the dampers and increase the fan speed (in models with NoFrost) or the intensity of refrigerant circulation. This allows you to quickly “break through” the thermal barrier that occurs when loading a large number of products at room temperature.
Differences from the SuperFrost and SmartFrost modes
Users often confuse the different accelerated operation modes of the refrigerator. In the Liebherr line there is a clear division of functions, and understanding these differences is critical for the correct operation of the equipment.
Mode SuperFrost is intended exclusively for the freezer compartment. Its task is to quickly freeze fresh food without defrosting the supplies already in the freezer. Cool Plus, in turn, works in the refrigeration compartment. Mode SmartFrost is generally a technology for the formation of ice on the walls, facilitating defrosting, and not the operating mode of the compressor.
Let's consider the main differences in the table for clarity:
| Parameter | Cool Plus | SuperFrost | SmartFrost |
|---|---|---|---|
| Area of action | Refrigerator compartment | Freezer compartment | Freezer compartment (covering) |
| Purpose | Fast cooling of food | Fast freezing | Simplification of defrosting |
| Impact on the compressor | Increasing operating time | Maximum power | No effect (passive technology) |
| Duration | Temporary/Manual | Automatic shutdown | Permanent characteristic |
Use Cool Plus is justified when you need to cool drinks before guests arrive or keep food fresh after a long trip from the store. Use SuperFrost is necessary when storing meat or berries for long-term storage.
Some advanced models Liebherr allow you to synchronize these modes, but by default they work independently of each other, serving different temperature zones inside the unit.
When it is necessary to activate Cool Plus
Mode Cool Plus is not intended for everyday constant work. Its activation is advisable in specific situations when the standard algorithm for maintaining temperature is not enough to preserve the quality of products.
Here are the main scenarios when you should use this function:
- 🛒 Loading warm products: If you brought a large number of products from the store that were at room temperature, placing them in the refrigerator will create a thermal load. Cool Plus will help quickly compensate for this warm.
- 🥤 Preparing for a party: When it is urgently necessary to cool a large number of drinks or dishes that will be served cold, this mode will reduce the temperature faster than usual.
- 🌡️ Hot weather: In the summer, when the temperature in the kitchen is significantly higher than normal, the refrigerator works with increased load. Turning on Cool Plus for a few hours will help stabilize the internal climate.
- 🍖 Storing perishables delicacies: If you plan to store foods with an extremely short shelf life for a short time, a lower temperature will prolong their freshness.
The mode is activated through the control panel. Depending on the Liebherr model, this may be a touch button with a corresponding icon or a switch in the settings menu. Usually the indicator lights up, signaling the start of operation in enhanced mode. Liebherr, this could be a touch button with a corresponding icon or a switch in the settings menu. Usually the indicator lights up, signaling the start of work in enhanced mode.
☑️ Check before activating Cool Plus
It is worth noting that after reaching the target temperature or after a certain time has passed (usually several hours), many models Liebherr automatically return to normal operation, which saves electricity and compressor life.
Impact on energy consumption and equipment life
Use of the function Cool Plus inevitably affects energy consumption. Since the compressor operates intensively without taking standard breaks, energy consumption increases. However, given that the mode is used for a short time, the overall impact on electricity bills remains minimal.
From the point of view of equipment life, modern compressors Liebherr are designed for such loads. Inverter motors, which are often installed in these refrigerators, are able to smoothly change power, which reduces wear on mechanical parts compared to sudden starts of conventional compressors.
However, there are certain limitations:
- ⚡ Overheating: When operating for a long time Cool Plus in a hot room, the refrigerator condenser can become very warm up. It is necessary to ensure good ventilation of the rear wall.
- 🧊 Icing: In models with a drip defrosting system (not NoFrost), intensive work can lead to faster accumulation of ice on the rear wall.
- 🔊 Noise: In mode With increased power, the noise level may increase slightly due to more active operation of the compressor and fans.
⚠️ Attention: If you notice that the refrigerator operates in Cool Plus continuous mode without your intervention, this may indicate a malfunction of the temperature sensor or a refrigerant leak. In this case, diagnostics are required.
Engineers Liebherr include a safety margin, so periodic use of enhanced cooling will not lead to breakdown. On the contrary, correct use of the mode helps preserve products, preventing their spoilage due to insufficient cooling.
Technical details of the compressor operation in the Cool Plus mode
In this mode, the electronic module removes restrictions on the minimum compressor rest time. If in normal mode the cycle can be 15 minutes of work and 20 minutes of rest, then in Cool Plus the rest cycles are shortened or disappear until the set temperature is reached.
Setting and control via the panel
Function control Cool Plus in refrigerators Liebherr simplified as much as possible for the user. The interface may differ depending on the series (for example, Comfort, Premium or BioFresh), but the logic remains the same.
To activate the mode, you usually need to perform the following steps:
- Press the power button or unlock button on the control panel (if there is a child lock).
- Find the button with the designation Cool Plus or a snowflake/drop symbol (depending on the model).
- Press and hold the button for 3-5 seconds until the indicator appears.
- The indicator will light up, confirming the activation of the mode.
In some models with a touch screen Liebherr control is carried out via the menu Settings → Cool Plus. There you can often set the duration of the mode or the temperature to which you want to cool the camera.
If the indicator on the panel is on Cool Plus, but you did not turn on this mode, check the settings. In some cases, the mode may be activated automatically when there is a sharp jump in temperature inside the chamber, for example, if the door has been left open for a long time.
Frequently asked questions and troubleshooting
When operating refrigerators Liebherr with the function Cool Plus users often encounter typical situations that are not breakdowns. Let's look at the most common of them.
If the indicator Cool Plus flashes, this may mean that the system cannot reach the set temperature. Check if the door is tightly closed, if the refrigerator is not overloaded and if it is not standing next to a heat source (radiator, stove).
Another common question: “Why are the products at the back wall covered with frost?” This is a direct consequence of the work Cool Plus. This is where the cold air comes out. In the enhanced cooling mode, the temperature in this zone may drop below zero.
It is important to regularly check the condition of the door seals. If they are worn out, the refrigerator will work in Cool Plus endlessly, trying to compensate for the loss of cold, which will lead to excessive energy consumption and wear on the compressor.
Is it possible to keep Cool Plus on constantly?
Technically, the refrigerator will work, but this is impractical. Constant operation at maximum power will lead to excessive energy consumption, possible freezing of food and a reduction in the service life of the compressor. Use the mode only when necessary.
Why does the refrigerator hum louder after turning on Cool Plus?
In the enhanced cooling mode, the compressor operates at higher speeds and without pauses. The fans of the NoFrost system (if equipped) also work more actively. This is a normal phenomenon, the noise level should decrease after turning off the mode.
Are Cool Plus settings reset when the power is turned off?
In most modern models Liebherr with electronic control, the settings memory is retained. However, after the power supply is restored, the mode Cool Plus may not be activated automatically; it will need to be turned on again to avoid network overload when all devices start simultaneously.
Does Cool Plus affect the operation of the BioFresh zone?
Mode Cool Plus primarily affects main refrigeration chamber. The BioFresh zone has its own insulation and humidity control system. However, a general decrease in temperature in the refrigerator may slightly affect the performance in BioFresh boxes, which is even useful for some types of products (for example, meat), but can be critical for vegetables.
Using the function Cool Plus in refrigerators Liebherr is an excellent way to adapt the equipment to your current needs. Proper use of this mode provides ideal storage conditions, preserving the taste and benefits of your products.
