Capacity
The total working volume of the freezer compartment. A larger volume allows for more products to be stored, but it affects the size and cost of the unit; therefore, when choosing based on this parameter, it's important not to chase maximum capacity but to consider what volume you actually need. For example, for household use, the average necessary volume is 50 liters per person; and when choosing a display freezer (see "Type"), you need to consider the number of products to be sold. More detailed recommendations for selecting the optimal volume can be found in specialized sources.
It is also worth considering that the freezer is often divided into several compartments (see below) — which means that a large volume does not necessarily guarantee that large pieces of products can fit into the device.
Climate class
The climate class to which the freezer 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 freezer 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 cool temperate 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). Freezer for a temperate climate, 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 they work at the range of external temperatures +18...+38 °C.
— T (tropical). Refrigerators for dry tropical climates. Designed for temperature range +18 °C to +43 °C.
Also, note that 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. These freezers are indispensable in climates, conditions which are not covered by one standard class — for example, in cold winters and hot summers.
Country of origin
It is the country in which, according to the manufacturer, this or that model is manufactured. Even though most of the capacities are concentrated in China, European factories for the production of household appliances have not disappeared. And some models can be produced there. In general, such a division into a Chinese or European factory should not particularly affect the quality of products, but the stereotype of a reliable European assembly is present. However, it is possible that the model may have a country of manufacture, for example, Poland, and in the store under the same article, you will meet China.
