When choosing modern household appliances for the kitchen, consumers are often faced with abbreviations and marketing names of functions, the meaning of which is not always obvious. One of these technologies is CoolPlus in refrigerators Liebherr. This is not just a fancy word on the front panel, but a complex engineering system developed by the engineers of the German brand to optimize cooling in different areas of the refrigerator compartment. Understanding what is hidden behind this term will help you operate the device correctly and keep food fresh longer.
The main task of the system is to create ideal conditions for storing various groups of products that require different temperature conditions. If standard cooling evenly distributes cold air, then The CoolPlus algorithm dynamically changes the operating parameters of the compressor and dampers depending on the mode selected by the user. This allows you to avoid overcooling of some zones and insufficient cooling of others, which is especially important when the refrigerator is fully loaded or storing specific products.
In this article we will analyze in detail the physical principles of the system's operation, consider the available modes and answer questions that often arise among equipment owners. Liebherr. You will learn how to properly use the functionality to save energy and extend the shelf life of your supplies.
Physical principles of operation of the CoolPlus system
Technology CoolPlus is based on an improved air circulation system inside the refrigeration chamber. Unlike static cooling, forced convection is used here. Cold air from the evaporator is forced by a fan and distributed through special channels located on the rear wall. The key element is an intelligent control unit that reads temperature sensors in real time.
When you activate one of the modes through the control panel, the system rearranges the operation of the compressor. Electronics Adjusts the fan speed and the position of the air dampers. This allows you to direct air flows of a certain temperature and intensity to specific areas. For example, the fresh vegetable zone requires higher humidity and a temperature closer to +4°C, while meat products require cold around 0...+2°C.
It is important to note that the system does not constantly operate at maximum power. Algorithm analyzes the thermal load. If you just put a bag of room temperature food into the refrigerator, CoolPlus temporarily increases the cooling intensity to quickly compensate for the heat. As soon as the temperature stabilizes, the system will switch to an economical maintenance mode.
⚠️ Attention: Do not block the air circulation holes on the back wall of the refrigerator with food or packaging. Violation of airflow can lead to incorrect operation of the CoolPlus system and the formation of condensation.
The efficiency of operation directly depends on the tightness of the chamber and the condition of the seals. If the door does not fit tightly, the system will try to compensate for the influx of warm air by constant operation of the compressor, which will lead to increased energy consumption.
Operating modes and their purpose
Functional CoolPlus in different models Liebherr may offer several preset scenarios. Each of them is optimized for a specific type of storage. The user can switch between them depending on what exactly you plan to fill the refrigerator with.
The most common mode is Standard (Standard). In this mode, the system maintains an average temperature of about +5°C throughout the entire volume of the refrigerator compartment. This is a universal setting for daily use, when a diverse set of products is stored in the refrigerator: from milk and eggs to ready-made meals and drinks.
For those who purchase food for several days in advance, the Eco (Eco) mode is intended. Here the temperature can be slightly increased (up to +6...+7°C), which reduces energy consumption, but maintains a sufficient level of cold for most products. However, for perishable goods, this mode may be less effective.
There is also a specialized mode for parties or large purchases, often called Party or Max Cooling. In this case CoolPlus reduces the temperature in the main chamber to minimum values (+2...+3°C) for a certain period of time. This is useful when you often open the door or put a lot of warm bottles.
Advantages of technology for food preservation
The use of advanced cooling systems, such as CoolPlus, provides tangible advantages compared to classic drip systems. The main one is the uniformity of the temperature field. The absence of “warm pockets” in the corners of the refrigerator prevents the growth of bacteria in areas where the temperature could be higher than critical.
In addition, the system helps maintain an optimal level of humidity. Rapid air circulation prevents moisture from settling on products, but at the same time, special filters or shelf designs (depending on the model Liebherr) prevent vegetables and fruits from drying out. This significantly extends the shelf life of fresh herbs, berries and lettuce.
Let's compare the storage characteristics with and without technology:
| Parameter | Without CoolPlus (Standard) | With activated CoolPlus |
|---|---|---|
| Shelf life of greens | 3-4 days | up to 7-9 days |
| Risk of defrosting during jumps | High | Low (fast compensation) |
| Temperature distribution | Uneven (difference up to 4°C) | Uniform (difference up to 1°C) |
| Condensation formation | Possibly | Minimum |
It is also worth noting the protection against “heat shock”. If you return from the store and put food in the refrigerator that has already begun to thaw (for example, ice cream or frozen meat), the quick cooling mode will help restore the structure of the product, minimizing the loss of quality.
Activation and setup instructions
Function control CoolPlus is carried out through the control panel located on the door or inside the chamber (depending on from the series Liebherr). The interface can be touch or push-button. Before starting setup, make sure that the refrigerator is connected to the network and is operating in normal mode.
To activate the mode, follow these steps:
- 🔹 Press the button
ModeorFunctionon the control panel to enter the settings menu. - 🔹 Use the navigation buttons or sensor to select the icon corresponding to the desired mode (for example, a snowflake for maximum cooling or a leaf for Eco).
- 🔹 Confirm the selection by pressing the button
OKorSet. - 🔹 Wait for the sound signal or flashing indicator confirming activation.
In some models with the function SmartDevice control is possible through an application on a smartphone. This allows you to remotely switch the refrigerator to party mode before you arrive home.
☑️ Check before setting the mode
After activating the new mode, the system requires time to rebuild. This process usually takes from 2 to 6 hours. During this period, the compressor may operate more noisily or intermittently - this is a normal situation, indicating the operation of algorithm stabilization.
⚠️ Attention: Do not activate the maximum cooling mode (Max Cooling) on a permanent basis. Prolonged operation at low temperatures can lead to freezing of vegetables and fruits, as well as increased wear on the compressor.
Energy efficiency and impact on electricity consumption
The issue of energy consumption often worries equipment owners. The technology is CoolPlus designed to strike a balance between performance and savings. In standard mode (Standard) and mode Eco the system operates very efficiently, often consuming even less energy than older refrigerators without smart electronics, thanks to precise control of the compressor operation.
However, using intensive cooling modes (Party, Max) temporarily increases energy consumption. The compressor runs at high speeds, consuming more watts per hour. But since these modes are usually used for a short time (several hours), the overall annual increase in electricity costs will be minimal.
For maximum savings it is recommended:
- 🔌 Use the mode Eco during vacation periods or when the refrigerator is not fully loaded.
- ❄️ Not set the maximum cold mode if there is no urgent need for it (for example, for defrosted foods).
- 🚪 Make sure that the door does not remain open for more than 30-40 seconds.
Modern models Liebherr often have an energy consumption class of A++ or A+++. The implementation of the system CoolPlus exactly allows you to achieve such indicators due to the absence of idling and precise dosing of cold.
Fault diagnosis and maintenance
Although the system CoolPlus is reliable, during operation situations may arise that require attention user. Most often, problems are associated not with the breakdown of electronics, but with violation of operating conditions.
If you notice that food in one part of the chamber freezes and spoils in the other, check the following:
- Are the ventilation holes on the back wall blocked.
- Is the temperature setting set correctly for the current filling.
- Is the door seal OK (test with a sheet of paper).
If error codes appear on the display (for example, flashing temperature symbols), the system itself diagnoses the problem. This may be a signal about compressor overheating or a sensor malfunction. In such cases, it is recommended to unplug the refrigerator for 10-15 minutes to reboot the controller.
What to do if the CoolPlus system does not respond to commands?
If the control panel does not respond, the interface may be blocked (Child Lock function). Try holding the lock button for 3-5 seconds. If this does not help, check the presence of voltage in the network and the integrity of the power cord.
Regular cleaning of the ventilation ducts from dust (usually required once every year or two during general cleaning) will also help the system work efficiently. To do this, you can use a vacuum cleaner with a soft nozzle, carefully walking along the grate on the back wall inside the chamber.
Frequently asked questions (FAQ)
Can I use the CoolPlus mode to freeze food?
No, mode CoolPlus only intended for the refrigerator compartment (temperatures above 0°C). For freezing, you must use the freezer compartment and function SuperFrostif it is provided in your model. Liebherr.
Why does the refrigerator hum loudly after turning on the party mode?
In intensive cooling mode (Party/Max), the fan and compressor operate at increased speeds to quickly reduce the temperature. This is fine. After a few hours, when the temperature stabilizes, the noise level should decrease.
Are CoolPlus settings reset when the power is turned off?
In most modern models Liebherr the settings memory is retained. When power is restored, the refrigerator will return to the last selected operating mode. However, if the shutdown was long, the temperature inside the chamber will increase, and the system will need time to restore the mode.
Does CoolPlus technology affect the taste of products?
Directly - no. However, by maintaining a stable temperature and humidity, the system prevents weathering and oxidation of products, which indirectly preserves their original taste and aroma longer than under normal conditions.
