When choosing modern household appliances, consumers are often faced with abbreviations that are not always clear without a deep dive into technical manuals. One of these functions, which raises many questions among owners of premium equipment, is CoolPlus. This technology, developed by a German concern Liebherris not just a marketing ploy, but a complex engineering system for controlling air flows.
The essence of the technology is to create optimal conditions for storing products due to the uniform distribution of cold. Unlike standard systems, where cold air can stagnate or blow directly onto the food, CoolPlus provides gentle cooling. This allows you to significantly extend the shelf life of fresh vegetables, fruits and meats without drying them out.
Understanding how this system works will help you get the most out of your refrigerator. In this article, we will analyze in detail the physical basis of the technology, how to activate and configure it, and also answer frequently asked questions.
The principle of operation of the CoolPlus system
The technology CoolPlus is based on a multi-stage air circulation system inside the fridge compartment. Engineers Liebherr implemented a mechanism that prevents the formation of zones with different temperatures. Cold air is supplied through special channels located in the rear wall, but its movement is strictly controlled electronically.
The key element here is the temperature sensor, which reads readings at different points in the chamber. Based on this data, the system makes a decision to turn the fan on or off. This allows you to maintain a given temperature with high accuracy, eliminating sudden jumps, which are detrimental to many products.
It is important to note that the system works in tandem with other brand technologies, such as VarioZone or DuoCooling. This creates a single microclimate where humidity and temperature are in perfect balance.
Technical details of the fan operation
The CoolPlus system fan operates at low speeds, creating a laminar air flow. This reduces the noise level and prevents chapping of products, in contrast to the powerful flows in conventional No Frost systems.
Differences between CoolPlus and classic No Frost
Many users confuse CoolPlus with the conventional “no frost” system, but there is a significant difference between them. Classic No Frost often leads to over-drying of products due to the constant active circulation of dry cold air. The system CoolPlus solves this problem through intelligent humidity control.
In refrigerators with this technology, the air does not just circulate around the chamber, but passes through special filters and humidifiers (depending on the model). This allows you to maintain the natural moisture of vegetables and fruits, preventing them from wilting. At the same time, an ice crust does not form on the walls, requiring defrosting.
Let's compare the main characteristics for clarity:
| Parameter | CoolPlus (Liebherr) | Classic No Frost |
|---|---|---|
| Air circulation | Intelligent, dosed | Constant, active |
| Humidity | Optimal, adjustable | Reduced, dry |
| Safety products | High, without drying | Medium, possible drying |
| Energy consumption | Optimized | Standard |
So Thus, CoolPlus is an evolution of the No Frost technology, aimed at preserving the quality of products, and not just at the ease of maintenance of the refrigerator. This is especially important for those who purchase products rarely and store them for a long time.
How to activate and configure CoolPlus
Management function CoolPlus is carried out through an electronic control panel located on the door or inside the refrigerator compartment, depending on the model Liebherr. The interface can be touch or push-button, but the logic of operation remains similar.
To activate the mode, you must press the corresponding button or select an item in the settings menu. On some models, the system may be activated by default. If you want to change the parameters, follow the instructions included with your specific model.

Setting the temperature mode also plays an important role. It is recommended to set the temperature in the main chamber in the range +4...+5°C. At this temperature, the system CoolPlus works most efficiently, ensuring a balance between energy consumption and food safety.
In models with advanced functionality, cooling intensity can be adjusted. You can select the "Eco" mode to save energy or the "Maximum" mode to quickly cool freshly loaded products.
Advantages of technology for food storage
Using refrigerators Liebherr with the system CoolPlus gives a number of undeniable advantages. First of all, this concerns the quality of storage. Vegetables and fruits stay fresh and crisp up to two times longer than in conventional refrigerators.
Meat and dairy products also benefit from stable temperatures. The absence of temperature changes prevents the growth of bacteria and spoilage of food. This is especially true in the summer, when the temperature in the kitchen can be high.
- 🥦 Preservation of vitamins and microelements in vegetables due to optimal humidity.
- 🥩 Preventing the formation of mucus and unpleasant odor on meat products.
- 🧀 Cheeses and delicacies are not ventilate and do not lose their aroma.
- 🍋 Citrus fruits do not dry out and remain juicy for several weeks.
In addition, the system promotes a more uniform distribution of odors. If you store foods with strong odors (such as fish or spices), they will not permeate the rest of the food in the compartment.
Operating modes and intelligent control
Modern refrigerators Liebherr equipped with an intelligent control system that automatically adapts operation CoolPlus to current conditions. Sensors monitor the frequency of door opening, ambient temperature and the number of loaded products.
Based on these data, the algorithm selects the optimal operating mode of the compressor and fan. For example, if you open the door frequently, the system will increase the cooling intensity to compensate for the loss of cold. At night, when the refrigerator is not touched, the system will switch to energy-saving mode.
Some premium models are available for control via a smartphone. A special application allows you to remotely monitor the temperature and change settings CoolPlus. This is convenient when you return from the store with a lot of groceries and want to prepare the refrigerator in advance.
There is also a "Party" or "SuperCool" mode, which temporarily boosts the system to quickly cool drinks and snacks. After reaching the set temperature, the refrigerator will automatically return to standard settings.
Energy efficiency and noise level
One of the important aspects of operating household appliances is its energy consumption. The technology CoolPlus is developed taking into account the requirements of high energy efficiency. Intelligent fan control allows you to reduce the load on the compressor, which leads to energy savings.
Unlike older models, where the fan worked constantly, the system Liebherr turns it on only when it is really necessary. This not only saves resources, but also reduces the noise level.
The noise level in refrigerators usually does not exceed 38-40 dB, which is comparable to a whisper. This makes the equipment comfortable for use even in small studio apartments, where the kitchen is combined with the living room.

This makes the equipment comfortable for use even in small studio apartments, where the kitchen is combined with the living room.
⚠️ Attention: The noise level may increase slightly when the compressor starts or when the super-cooling mode is activated. This is a normal operating process and does not require intervention.
Regular cleaning of dust from ventilation openings also helps maintain high energy efficiency and low noise levels. It is recommended to carry out this procedure at least once a year.
Typical questions and troubleshooting
Despite the reliability of the equipment Liebherr, users may encounter operational questions. People often ask why the indicator CoolPlusdoes not light up. In most cases, this means that the system is running in the background and does not require status display, or the mode is disabled in the settings.
Another common question concerns the formation of condensation. In a working refrigerator, condensation should not appear on the back wall. If you notice water dripping, check that the vents are not blocked by food and make sure the door closes tightly. CoolPlus Condensation should not appear on the back wall. If you notice water dripping, check that the vents are not blocked by food and make sure the door closes tightly.
