What is the climatic class of the refrigerator and which one is better
Choosing a modern refrigerator, it is extremely important to understand what the differences are in the models, and which one will be the best option for you. Leaving other characteristics of these irreplaceable household devices, in this article we will consider what is the climatic class of the refrigerator, and why it is used.
When deciding to buy a refrigerator, most often we are guided only by the capacity of the main and freezer, power (W), the presence of "smart" functions and, of course, the appearance of the whole device. Even from a sales consultant, you rarely hear anything about data classes of household appliances; what can we say about the recommendations on what is better to choose. But this parameter should be one of the main selection criteria, since the life of the refrigerator depends on it.
What is a climatic class and why is it needed?
The climatic class of the refrigerator (S, SN, ST ...) indicates to the user what temperature should be in the room where the operation of the device is planned. If this requirement is not respected (for example, a refrigerator for a cold climate will work in a hot the risk of not only deteriorating the quality of food storage, but also the rapid breakdown of all device. Manufacturers equip their models with compressors of such power, which is enough to maintain the difference in temperature outside and inside the refrigerating chambers in a strictly limited range.
The buyer will be very helpful to know what climatic conditions are suitable for operating a particular model, and, depending on this, make the final choice. In this case, you can rely on warranty repair of equipment, the right to which can be denied, if a violation of the temperature regime is established. Legally it is the user will be extreme, as he violated the rules of operation of the refrigerator, indicated both in the technical passport, and on a special sticker on the case.
No one will care what the store manager did not explain to the buyer what the symbols (N, T, SN, ST) in the graph mean, which means the climatic class of the refrigerator. In the next chapter of the article you will find a detailed classification of classes with a description of their features.
What are the climatic classes of the refrigerator
To understand the fundamental differences that cooler classes have, see the table below.
| Class | Symbol of designation | Temperature range (C) | Note |
| Normal | N (UHL) | 16-32 | The most universal climatic class, which includes most refrigerators in Russian shops. However, residents of southern regions, where the temperature in summer can exceed 32 degrees, should remember: the operation of the refrigerator in this case is possible only in an air-conditioned room. Well, in winter, the house must necessarily be heated. N and SN in assemblies of domestic production can have the marking "UHL" (class for a moderately cold climate). |
| Subnormal | SN (UHL) | 10-32 | This climate class of refrigerators will be an ideal solution for rooms with unstable heating (cellars, chimneys, cold corridors ...), where the temperature can drop below comfortable. In units of domestic production ST can be referred to as "UHL". |
| Subtropical | ST | 18-38 | Suitable for regions where the summer is quite hot (above 32 degrees). |
| Tropical | T | 18-43 | The tropical class of refrigerators will allow them to feel great even in the most unbearable heat that will create either climatic conditions (in the southern regions), or the features of the room (south side, lack of air conditioning, small area). |
In the stores of household appliances, you can usually meet refrigerators of normal class (N), although their operation is possible only in a small territory of Russia. The remaining zones need subnormal (SN in the North), or subtropical and tropical (ST and T in the South). Why then do they offer us not exactly what we need? First, the price of a refrigerator of a normal class will be lower, because of what it is easier to sell; Secondly, there is always a "maneuver" in order to refuse warranty repairs.
Recently, manufacturers have started the production of "multi-class" refrigerators, which have a wider range of permissible temperatures (climatic conditions). But if you live in a normal home, where there is neither extreme heat nor too cold, it is enough to simply choose a class of four basic.
This will be enough for the long-term service of your refrigerator.
