Comparison Liebherr ICUS 3324 vs Liebherr ICUNS 3324

The total volume of a refrigerator is the sum of the volumes of all its compartments, which can vary in specific capacity between different models. It's important to consider this when choosing a refrigerator.

A larger volume for a refrigerator can be beneficial for accommodating more food, but it can also increase the price and size of the appliance. This is especially important to consider if you plan to build the refrigerator into a specific space.

The presence of the No Frost system in one or more refrigerator compartments.

This system prevents the formation of frost on the walls of the compartment, as happens in models without No Frost. No Frost is a technology used in refrigerators that removes moisture from the air inside to prevent frost buildup. It works by condensing water vapor and evaporating it outside the refrigerator. However, this feature can cause food to dry out more quickly, so proper packaging is essential.

In modern refrigerators, No Frost can be provided both in the refrigerator and in the freezer, and often in both compartments at once. When deciding whether to choose a No Frost refrigerator, it is important to weigh the benefits of not having to defrost against the possible downside of faster drying of food products. This feature is more advantageous for the freezer, as the benefits of No Frost are more significant at sub-zero temperatures and the disadvantages are less noticeable.

Common features that apply directly to the entire appliance include holiday mode, control via smartphone, child lock, display, door alarm, auto door closer, and reversible door. More about them:

— Holiday mode is an energy-saving feature intended for times when the refrigerator is not in use for an extended period, such as when there is no food inside. During this mode, the temperature inside the fridge compartment is kept around 12 degrees, which helps prevent the development of mold and unpleasant odors.

— Control via smartphone. This feature allows users to access and manage the unit from anywhere with an internet connection. This is achieved through Wi-Fi connectivity to a router or smart home system. The control can be done through a smartphone application or a web page available on any browser. This function provides users with information about the refrigerator's operating mode, including temperature, humidity, malfunctions, and emergency situations. The control via the internet is convenient and provides flexibility in controlling the refrigerator.

— Child lock. Many modern refrigerators come with safety features designed to prevent small children from tampering with the settings. These features usually involv...e locking the control panel to prevent accidental adjustments. However, child locks for the doors are not typically included as a standard feature and must be purchased separately.

— Display. Displays can be found on refrigerators of various levels, from basic to advanced models. Regardless of the level, the display adds convenience to the operation of the unit by providing detailed information about its operation and displaying useful data, such as the time. In some cases, the display can also integrate with other smart home components. However, the cost of refrigerators with such features is typically higher.

— Door alarm. The refrigerator door alarm system alerts the user if the door has been left open for an extended period of time or not closed properly. This prevents spoilage of food due to a critical increase in temperature. The alarm usually gives a sound signal after a certain amount of time and some models also have a light indicator to confirm the correct closure of the door.

— Auto door closer. Auto-closing devices are installed on some refrigerators and are responsible for assisting in the closing and, in some cases, opening of the door. This helps to reduce the risk of leaving the door partially open or closed, while also ensuring a smooth, shock-free movement that can prolong the life of the refrigerator.

— Reversible door. Refrigerators with a classic design offer the ability to choose the location of the hinges, allowing users to decide on which side the door will open for optimal access. note that this function is only available for classic design models, including refrigerated display cases (see “Type”). This feature is not available in Side-by-Side and French Door models due to their design.

The amount of shelves in a refrigerator determines the division of space within the refrigeration compartment. Larger refrigeration compartments generally have more shelves, but there are also various configurations available even within the same volume (3 shelves, 4 shelves, 5 shelves and more). It is worth considering that they are mostly removable, which allows you to adjust the height of the shelf. And if necessary, you can buy more.

In refrigerators with dynamic air cooling, the air inside the working compartment moves not due to the temperature difference, but due to the operation of the built-in fan. This ensures uniform distribution of cold air and the same temperature throughout the volume.

The primary function of the freezer is to store food in a state of deep freeze, which helps preserve perishable products such as meat, vegetables, fruits, etc. for extended periods of time. The necessary volume of the freezer depends on the planned amount of food to be stored and the length of time it will be stored. A larger freezer is particularly useful if you plan to store food for several months. A compact freezer is relevant for short-term storage (for a day or two) or for seasonal devices (for example, in the village). It is best to ensure that the freezer is not overloaded and has enough space for proper circulation of air to maintain the desired temperature.

Refrigerators with good thermal insulation can maintain low temperatures inside for a significant amount of time even if there is a power outage. This period of time is known as the "keep cold time," during which the refrigerator can preserve perishable food items. A longer keep cold time indicates better thermal insulation, making the refrigerator more suitable for areas where power outages are common.

The freezing capacity of a refrigerator refers to the amount of fresh food it can freeze from room temperature to the freezer temperature within a 24-hour period. For everyday use, a freezing capacity of up to 10 kg/day is sufficient, but if you frequently freeze large volumes of food, you should consider a more powerful freezer.

The average amount of energy consumed by a refrigerator in a year of operation.

The given parameter is an estimated value and assumes that the refrigerator operates under stable conditions without sudden temperature changes, frequent door openings, and within its designated climate class (see below). Actual energy consumption may deviate slightly from the stated value. Despite this, it is a useful parameter that allows for a rough comparison of different models in terms of energy efficiency.

It should be noted that the energy consumption per year is often a more practical and convenient parameter than the energy consumption class (see above), which is a relative indicator of how efficient a refrigerator is compared to other models of similar size and features. The energy consumption per year, on the other hand, provides an estimate of the actual electricity cost when using a particular refrigerator. For instance, a small two-door refrigerator with an energy class of A can consume less energy per year than a large side-by-side refrigerator with a class of A+++, despite the fact that the latter is formally more energy-efficient than the former in terms of its energy class.
