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 total capacity of the main working chamber of the refrigerator. If there are separate zero chambers, compartments for wine and other additional functions, this paragraph takes into account only the volume of the refrigerating chamber itself, without additional equipment. In the smallest modern units, this figure does not even reach 100 liters, in the largest it can exceed 400 liters.

The choice of capacity depends on the actual storage needs of the products. At the same time, both the volume of stocks and the frequency of their replenishment (every day, once a week, etc.) matter. The chamber should not be stocked completely; this adversely affects the quality of the refrigerator. On the other hand, it is worth remembering that large volumes accordingly affect the dimensions and price of the unit.

In general, for one or two people, a capacity of 200 – 250 liters, or even less, is considered quite sufficient. The optimal capacity for a family of three is about 250 – 300 liters, for four to five people — 300 – 350 liters, and larger volumes are really needed mainly for specific situations when food has to be stored in large quantities and for a long time.

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.

Separate zones that help expand your food storage options. Among these there are multizone — , fresh zone, humidity zone, low temperature zone, wine chamber, bottle rack. More details about them:

— Fresh zone. A special compartment designed for long-term storage of fresh vegetables, herbs and other similar food. Such a compartment can be made in the form of a completely separate chamber. In such cases, it is called the zero chamber and its volume is separately indicated in the specifications. However, more often the fresh zone is located inside the main compartment. Anyway, the humidity in this zone is somewhat higher than in the refrigeration compartment, and the temperature is somewhat lower: in some models, it is about zero (which allows you to store raw meat or fish), in others it is about +1 .. .3 °C (this is only suitable for fruits, vegetables and cheeses). Anyway, the moisture from the products in the fresh zone does not evaporate as quickly as in the main chamber, and the contents retain their original appearance and taste longer. This feature is especially useful if there is a No Frost system (see above) in the refrigeration chamber of the unit.

— Humidity zone. Another feature designed for long-term storage of fresh food is similar to the fres...h zone described above. The difference is that freshness is preserved solely due to the increased humidity of the air (hence the name). The temperature corresponds to the temperature in the refrigeration chamber. The humidity zone is intended mainly for storing vegetables and fruits; in some refrigerators, this compartment has a humidity control that allows you to optimally adjust it to different types of contents (detailed recommendations on this can be found in special sources)

— Low temperature zone. A compartment in which a lower temperature is maintained than in the main chamber of the refrigerator. Typically, fresh meat or fish are supposed to be stored in the low-temperature compartment. The presence of such a compartment allows you to more effectively organize long-term storage of food in the refrigerator and keep it fresh longer.

— Multizone. A compartment that combines the functions of several compartments at once. The simplest option is the ability to work in the mode of a refrigerator or freezer. However, in modern refrigerators, there are multizones with more extensive capabilities. These features can be quite specific — like quickly cooling drinks, slow defrosting, and even cooling hot dishes. So the specific features of the multizone should be specified separately. Nevertheless, its presence significantly expands the capabilities of the refrigerator. Also, in some models, the entire freezer performs the function of such a chamber. However, most often the multizone is still designed separately from other chambers.

— Wine chamber. Specialized compartment for long-term storage of wine. Usually, a temperature of +10..12 °С is maintained in such a compartment — it is this temperature considered optimal for this task. Some models may also provide the possibility of more precise temperature settings — for different types of wine. The traditional equipment of a wine chamber includes a shock-absorbing system that dampens vibrations from the compressor and other shocks, as well as carbon filters to protect against foreign odours; and the door of such a chamber is traditionally made transparent — so that you can see the collection of wines without opening the refrigerator.
Nowadays, this function is found only in some premium refrigerators. It is because most wine connoisseurs prefer to use specialized wine coolers: such devices are less bulky and often more functional.
— Bottle rack. Shelf of a special design for the convenience of storing bottles in the refrigerator. It has the form of stands of a wavy shape. In the recesses of such "waves" it is convenient to keep bottles of small or medium size: they do not roll over the refrigerator and are at hand; you just need to open the door.

This function means that there is a built-in fan that circulates air around the refrigerator compartment. It contributes to the evenest distribution of cold and more efficient cooling than in units without a fan, where the air moves only due to natural convection. The main disadvantages of dynamic air cooling are the increase in noise level, energy consumption and the cost of the refrigerator.

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.

The average amount of energy consumed by a refrigerator in a year of operation. Of course, these figures are not absolutely accurate; the actual power consumption may vary depending on the specific operating conditions. However, this parameter makes it possible to evaluate the power consumption of the refrigerator and compare different models with each other. At the same time, it often turns out to be more convenient and visual than the energy consumption class (see above) because in this paragraph we are talking about a specific figure (from which you can also calculate the cost of electricity consumed). For clarity, let's take the following example: a small two-chamber refrigerator with energy class A can consume less energy per year than a large side-by-side unit of class A+++, although formally, in terms of energy consumption classes, the second model will be more economical than the first.

The climate class to which the refrigerator corresponds.

As the name implies, this parameter describes the environmental conditions for which the unit is designed. The warmer it is around — the more powerful the refrigerator should be and the better thermal insulation it should have. Specific classes are indicated by letters, here are the most popular options:

— SN (subnormal). Models for a temperate cool climate, have an operating range from +10 °C to + 32 °C. Such a unit can be useful in a poorly heated room where the temperature can drop below +16 °C — for example, on the veranda of a private house, in a garage, etc.

— N (normal). Refrigerators for temperate climates, with an operating temperature range of +16...+32 °C. Such a unit is suitable for most residential apartments and houses in mid-latitudes.

— ST (subtropical). Models for subtropical and humid tropical climates. Normally work at the range of external temperatures +18...+38 °C.

— T (tropical). Refrigerators for dry tropical climates. Designed for temperature range +18 °С to +43 °С.

There are many models on the market with an extended temperature range covering several classes. For example, a unit labelled N-ST will have a temperature range of +16...+38 °C. Such refrigerators are indispensable in complicated...climates, the conditions of which are not covered by one standard class — for example, during cold winters and hot summers.

The country in which this refrigerator model is manufactured (according to the manufacturer).

There are many stereotypes associated with the relationship between the origin and the quality of household appliances. Thus, the location of production in Europe ( Germany, Lithuania, Poland, Romania, Serbia, Turkey, etc.) is considered more prestigious than in Asian countries ( China, Thailand) or CIS countries ( Belarus, Russia, Uzbekistan, etc.). And different European countries have a different reputation among buyers in this regard. However, these stereotypes should be treated with considerable distrust: the actual quality of products depends not so much on the geography of production, but on the quality of the organization of processes by a particular manufacturer. As a result, equipment of a similar level, produced by different brands in the same country, may differ markedly in actual quality.

It is worth to say that the same refrigerator model can be produced in several countries at the same time. And units of the same model, produced at different times at different plants, may be on the market at the same time. As a re...sult, it happens that one country of production is indicated in the general characteristics of the model and another in the documentation for the unit purchased. It is quite a normal situation. However, if the country of production is still important for you, you should clarify this point in advance before buying.
