Refrigerator capacity
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.
Freezer capacity
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.
Energy class
Refrigerator energy class according to the old European standard valid until 2021.
The energy class shows how economical the unit is compared to other models with similar specifications. It is used for devices manufactured before March 1, 2021. Initially, in this standard, classes were designated in Latin letters from A (most economical) to G (high power consumption). However, later improved classes A+, A++, and others appeared. (the more pluses, the more effective is the device). For modern refrigerators, marking A according to the old system is actually the minimum level of energy efficiency specific for outdated and low-cost devices; most models are classified as
A + and
A ++, and most
A+++. There is no need to wait for more pluses. Since 2021, all new equipment will be marked according to the new system, where class G will correspond to the old class A, class F to class A+ and so on.
Note that a higher energy efficiency class (with similar specifications) means a higher price but this difference can quickly pay off due to energy savings.
Climate class
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.
