Comparison Liebherr CP 4813 white vs Liebherr CN 4813 white

The total capacity of the refrigerator is the total capacity of all the main working chambers: refrigerating, freezing, zero, and wine chambers. The set of these chambers, of course, will be different in different models (see more about them above). Here we note that large volumes, on the one hand, simplify the storage of numerous products and, on the other hand, affect the dimensions and price of the unit. It is also worth considering that refrigerators of the same total capacity may differ in the capacity of individual chambers.

The No Frost function prevents the formation of frost inside the refrigerator. The general principle of its operation is that excess moisture is blown out of the working chamber by a special fan, not having time to settle on the walls and form frost.

This function is most relevant for the freezer, although it is technically easy to provide in the refrigerator. Therefore, refrigerators with No Frost in all compartments are the most popular nowadays, much less often this system is installed only in the freezer, and extremely rarely — only in the refrigerator (usually in such models there is no freezer at all).

The No Frost function significantly simplifies the user's life. It eliminates the need to manually defrost the refrigerator and even eliminates the need for automatic defrosting systems (see "Features"). The reverse side of this convenience is that such systems absorb moisture not only from the air but from the food inside too. So for long-term storage, the contents must be tightly packed — otherwise, it dries quickly. In addition, the presence of No Frost inevitably increases the overall cost of the fridge. So if these moments are critical for you, the fridges without No Frost may well be the best choice.

The number of shelves supplied with the refrigerator. In this case, only shelves placed inside the main (refrigeration) chamber are taken into account. And closed drawers, which are usually at the bottom, are not considered shelves.

In general, this amount depends on the volume: the more spacious the refrigeration compartment, the more shelves are usually provided in the kit. At the same time, there is no strict dependence here, and refrigerators of similar capacity can be equipped with a different number of shelves. As for specific options, the most modest models come with 1 – 2 shelves, 3 shelves and 4 shelves can be called an average, and more are found in some units.

In most modern refrigerators the shelves are removable. In addition, they can be installed at different levels. In this case, it is not necessary to use the entire set: for example, if it is planned to place tall objects inside, one of the shelves can be removed, creating a vast space. And vice versa: if necessary, you can, usually, buy additional shelves. So the number of shelves in the kit only allows you to evaluate the overall possibilities for organizing space in the refrigerator. How to use these features depends on the user.

Forced cooling mode, in which the intensity of cooling the refrigeration compartment is significantly increased. It is an analogue of the fast freeze described above, used in the refrigerator compartment. Fast cool is also intended mainly for situations where a lot of foodstuff must be loaded inside at a time — it avoids a critical increase in temperature inside the refrigerator. This mode also needs to be turned on in advance and turned off after a certain time. In some models, the shutdown occurs automatically, but the presence of this feature needs to be specified separately.

The capacity of the freezer installed in the refrigerator. Such a chamber is designed to store products at temperatures well below zero (on average -18 °C). Its capacity is related to the total capacity of the refrigerator (and the capacity of the main, refrigerating chamber). However, there is no strict dependence here — models with a similar volume of the refrigerating chamber can be equipped with freezers of different sizes.

When choosing by capacity, it is worth considering how much frozen food you plan to store at a time. Note that it is undesirable to fill the freezer completely — this negatively affects the efficiency of work. However, if this chamber is planned to be used only occasionally, and you do not plan to keep numerous products in it, you can not chase after the capacity: for such cases, 25 – 50 liters, or even smaller capacities, are enough. In the smallest modern refrigerators, the freezer capacity does not exceed 10 liters. And vice versa, very roomy freezers come across — for 176 – 200 liters and even more. Such volumes are typical mainly for side-by-side and French door units (see "Product type"). However, they are also found in models of the classic two-chamber layout.

The number of drawers into which the refrigerator freezer is divided. For top-mounted freezers (see “Freezer”), this paragraph may indicate the number of levels, taking into account the shelves the fridge is equipped (drawers are not used in such chambers).

On the one hand, the abundance of drawers makes it easy to distribute different types of foods in different compartments. On the other hand, more drawers (for the same total freezer capacity) mean less height and capacity for each drawer. So when choosing, you should consider what is more important for you — extensive possibilities for sorting content or the capacity of individual drawers. As for the specific quantity, most modern refrigerators have 3-drawer freezers — this number is generally considered the best compromise between the nuances described above. A larger number of drawers is found mainly in high-capacity units, but 1 – 2 freezer drawers can be found in all types of refrigerators — from small classic to large French Door and Side-by-Side (see "Product type").

The operating temperature of the refrigerator freezer.

The generally accepted standard for freezers is actually -18°C. It allows you to effectively store pre-frozen foods, as well as freeze them (with certain precautions). At the same time, for most modern refrigerators, lower temperatures are claimed — at -24 °C, and in some models even lower. However, such indicators are not always standard — in many units, they are achieved only in the fast freeze mode (see "Features"). This should be clarified separately. However, the temperature of the freezer below -18 °C means good freezing features.

In turn, chambers with more modest minimum temperatures — -12 °C, or even -6 °C — are only suitable for storing pre-frozen products; they are not suitable for freezing any significant amount of contents. However, there are very few refrigerators with such indicators on the market — mostly low-cost or outdated models.

To indicate the temperature of the freezer, markings in the form of asterisks (snowflakes) are often used, each of which means a decrease in temperature by 6 °C. For example, in models at -24 °C, you can find the designation * (***) — four asterisks, one of which is highlighted. This usually means that in the standard mode the freezer operates at -18 °C (three stars), and at another 6 °C (down to -24 °C) the temperature drops during fast freezing.

The autonomy time provided by the refrigerator when the power is turned off.

Often, this parameter describes the capabilities of the freezer. In such cases, the autonomy time is indicated as the time during which, at an outside temperature of +25 °C, the temperature in the filled freezer does not rise above -9 °C (this level is considered critical for the storage of frozen foods). Accordingly, the actual autonomy time may differ from the claimed one — depending on the ambient temperature, the frequency of opening the refrigerator, etc. However, this parameter describes the quality of thermal insulation quite accurately, and it is possible to evaluate different models and compare them with each other.

Also, autonomy time can be given for models without freezers: in such cases, we are talking about the time during which the temperature in the refrigerator compartment remains at an acceptable level under approximately the same conditions.

Approximate amount of fresh food that a refrigerator can completely freeze from room temperature to freezer operating temperature in 24 hours. Power up to 10 – 15 kg/day will be quite enough for everyday use, but if you plan to freeze food in large volumes and often — you should pay attention to more performant freezers.
