When choosing a product for storing food chilled, users first of all look on the manufacturer, because they trust only proven models, then they are interested in volume and study the technical parameters, and practically no one ever, with rare exceptions, pays due attention to the climatic class of the refrigerator.
Each potential buyer should know that the proper operation of the refrigerator will depend on this parameter, and its powervolume sizes, as well as other characteristics will already be of secondary importance. Many users do not even know what this parameter is and how it affects the working conditions of products for cooling and freezers. To eliminate the gaps in your horizons, just take the time to carefully read our article.

What is the climate class of the refrigerator
Latin characters indicated on a special label located on the back of household appliances indicate exactly what class it belongs to. Such a sticker appears on each product after checking the quality control system, English letters, which we will talk about a little later, give the user an indication of what optimal temperature in the room should be used for this device.
Many users do not even assume that in case of violation of these recommendations, household appliances will quickly fail, because the difference between the external and internal temperatures will not correspond to the power compressorAs a result, he will quickly exhaust his life, constantly turning on cooling. Therefore, you must familiarize yourself with the classification of climatic conditions before buying a refrigerator.
Legally, it is you who will remain to blame for the premature failure of the equipment, because you have violated all the product operation rules prescribed by the manufacturer that are indicated in the technical passport. In this case, warranty repair or replacement of parts is not possible - all work will be performed at the user's expense.
What classes exist
For clarity, the entire climate classification is tabulated:
| Symbol | Temperature range C | Optimum Use |
| Normal (N) | 17—32 | A universal climate class, but during the hot summer period, operation must be carried out using an air conditioner. |
| Subnormal (SN) | 10—32 | An ideal solution for rooms with an unstable heating option (utility rooms, basements of private buildings, unheated internal corridors). |
| Subtropical (ST) | 18—38 | The southern regions of Russia, where the peak of summer temperatures is above normal. |
| Tropical (T) | 18—43 | Designed for rooms with high temperatures in the summer due to the lack of air conditioning or for some other reasons. |
The first two classes in domestic products are designated UHL, which means a mild-cold climate. In the domestic market of Russia, the third and fourth grade are almost never found.
Many manufacturers of world renown began to produce multiclass type models that are designed to operate subject to a wider temperature dispersion, for example, 10-43 degrees, and some models can support all 4 classes. This means that such universal products have higher energy saving indicators, and, accordingly, the cost is much higher.
Way to learn class
For those who still have not figured this out, we explain in detail: all information about the climate option is contained on a special label that is located on the back of the refrigerator or the inside of the refrigerator. Each potential buyer can find out the information he is interested in by carefully examining a favorite model.
Similar parameters are indicated in the technical passport of the product - upon purchase, it is necessary to check the accuracy of filling out the warranty card, which indicates the date and seal of the store, as well as the signature of the seller or sales person, for example, the manager of the household goods department.
It is better to check all the documentation before payment at the cash desk, and in the case when the order was made via the Internet, then you need to sign the acceptance certificate after unpacking, checking the product, establishing the identity of the passport data and the sticker on the back.
Features
Many users are confused energy class and climate designations, but the first indicates only the number of kilowatts that the device consumes for a certain time, for example, per hour, day, per month or per year. International symbols use Latin letters from A to G, but recently quite a lot of models with the following symbols have been released: A +, A ++ and A +++ - this means that you have a product of the highest energy saving class.
Climatic classification uses only three letters - N, S, T and their combinations (see table). The degree of performance, taking into account the ambient temperature, will depend on such parameters:
- Compressor power. The higher the class, the more powerful the unit responsible for the exchange of refrigerant in the product cooling system. ST and T classes are equipped with compressors with increased performance.
- The thickness of the insulation layer. The higher the ambient temperature, the thicker the similar layer will be. For the manufacture of refrigerators, which are designed for continuous operation in a tropical climate with a high percentage of humidity, special materials resistant to mold are used.
- Heat transfer area. Products for the subtropics and tropics are equipped with evaporators and condensers of a much larger area than devices for working in temperate climatic zones.
- Additional ventilation - it is used to cool the condenser to speed up the process and the efficiency of heat transfer.
Naturally, more powerful refrigerators will consume more electricity, but within reasonable limits.
The art of making the right choice
A wise user before visiting a shopping center or a specialized household goods store to buy a new refrigerator, selects a model on the Internet, gets acquainted in advance with its performance characteristics (TTX). It is useful to measure the average temperatures in different climatic periods to find out which class will be optimal for the conditions of your room, where the refrigerator is installed.
Today, manufacturers offer products of the combined class, working properly at operating temperatures from 10 to 45 degrees and even higher, due to global warming. For example, in many northern regions last year an abnormally high temperature was recorded, both in summer and in autumn. It should be borne in mind that multiclass products will consume more electrical energy, and their cost is much higher.
Therefore, for the average Russian consumer, the first two climate class refrigerators will still be the best option, not only because they are much cheaper - the temperature inside city apartments rarely rises above 30 degrees, even without air conditioning equipment, it is enough to use blinds or dense curtains. In the kitchen, in addition, during cooking, an extract hood is turned on, which normalizes the microclimate.
findings
If the refrigerator is positioned correctly - away from central heating batteries and a gas stove, then the compressor will turn on less often in the evening, when containers with cooked food will be placed inside the product. The experience of using modern household appliances shows that, despite sharp changes in the climate towards high temperatures in the summer, products for cooling products work properly if users do not violate operating conditions.
