Comparison Liebherr ICUNS 3324 vs Liebherr ICUN 3324

The circuit in a refrigerator refers to the cooling system connected to the compressor. Typically, the number of circuits corresponds to the number of compressors, but some models have two cooling circuits are connected to a single compressor for the refrigerator and freezer. While a dual-circuit refrigerator with one compressor cannot turn off one compartment while keeping the other functional, it allows for separate temperature control.

Apart from shelves, there are several additional compartments in a refrigerator, including a a freshness zone, a humidity zone, a multi-zone and a shelf for bottles.

— Freshness zone.It is a special compartment in a refrigerator designed for storing fresh products for an extended period. The temperature in this zone is slightly lower than the refrigerating chamber, typically around zero degrees, earning it the nickname "zero chamber". Such conditions help to preserve the freshness of products for up to 3-4 days. However, it's important to note that the temperature in the zero chamber may vary depending on the refrigerator model, ranging from 0 °C to +1...3 °C, which can impact the preservation of stored products.

— Humidity zone. Another specialized compartment, similar to the freshness zone, is designed to preserve the freshness of food items for an extended period. However, this compartment maintains high humidity at the same temperature as the rest of the refrigerator, which prevents the products from drying out. This feature is especially important for refrigerators with No Frost systems, which tend to blow moisture out of the refrigerator, leading to quicker drying of the contents.

— Multi-zone. This compartment in a refrigerator combines several functions of different compartments, such as the...ability to work as a refrigerator or a freezer, along with other specific features like quickly cooling drinks, slow defrosting, and cooling hot dishes. Modern refrigerators offer more extensive capabilities with specific features, making the multi-zone compartment a valuable addition. Some models have the entire freezer performing the function of a multi-zone chamber, but most models have a separate compartment for it. The presence of a multi-zone compartment significantly expands the capabilities of a refrigerator.

— Shelf for bottles. It is a hanging accessory, typically in the form of a lattice, that is installed under a shelf in the refrigerator. It allows bottles to be stored horizontally, which saves space in the refrigerator while keeping them organized.

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.

— Door sliding — a special type of mount for a built-in refrigerator, in which the decorative facade rests on the hinges of the cabinet, and the refrigerator door itself is only partially loaded. The sliding fastening of a built-in refrigerator's facade allows the door of the fridge to slide along the guides on the inside of the decorative panel, reducing the load on the hinges and increasing the appliance's durability. However, this can create a gap where dust can accumulate, and the door can only open up to 90-95˚, which may cause inconvenience when accessing shelves and drawers.

— Door on door — a special type of fastening of a built-in refrigerator, in which the front decorative facade is hung directly on the refrigerator door. With this type of installation, the front decorative panel of the refrigerator is fixed directly onto the door hinges. The main advantage of this rigid attachment method is that the refrigerator door can be opened wider, up to 110-115˚ or even more. Furthermore, there is no gap between the door of the refrigerator and the decorative panel, which creates a sense of structural integrity. However, one drawback of this method is that it can create additional weight load on the refrigerator door hinges, leading to sagging if they are not designed to bear the weight of the panel.
