Many have come across such a parameter as the climate class of the refrigerator. It regulates the operating temperature of the device. Failure to comply with the requirements due to this parameter leads to poor quality of the device, as well as its breakdown.
Climatic classes of the refrigerator
Currently, there are 4 main classes of devices (international marking). Among them:
- Refrigerator climate class N. A versatile look for use in temperate climates, without prolonged heat or cold spells. Working temperature range of devices: +16°С..+32°С. The advantage of this type can be considered a low level of energy consumption. Models are suitable for use in residential buildings. But they are not suitable for operation in regions where the air temperature exceeds + 32 ° C (if the air conditioner is not working in the room).
Refers to the most affordable price segment.
LG is one of the best manufacturers of devices in this line. Also good and affordable models are produced by Indesit. However, NORD NRB 120,030 stood out in the segment.
- Climate class refrigerator SN. Products of this type can be installed in unheated rooms, as well as basements. Suitable for industrial use. Temperature range for optimal operation of such products: +10°С..+32°С.
Here, Liebherr, Bosch are considered the leaders in production (the best representatives are KIM 30471 SN, as well as KIF 20441 SN and KTL 15420 SN), Samsung.
- Refrigerator climate class ST. We use at high humidity, high temperatures. Representatives of this species are tolerant of temperature fluctuations. The only disadvantage of this class is that they cannot be used at low temperatures. The use of such products in our latitudes is possible only with good heating of the room (from 35 ° C).
In this segment, the best models are represented by Samsung, Electrolux or Miele. Good products from this group: Sharp SJ PV 50 HG or SJ PV 50 HW.
- Refrigerator climate class T. Fully adapted for operation in dry and hot climates. Operating temperature range of such devices: +18°С..+38°С. They have increased thermal insulation, which is why the purchase is more expensive than other classes of products. Not suitable for use in high humidity conditions.
On the territory of the CIS, the use of class T refrigerators is extremely unprofitable and impractical.
The best models of this type are produced by Samsung and Whirlpool, as well as some other companies. Particularly popular samples: Panasonic NR-B 591 BR-C4, also Whirlpool ARC 4208 IX.
Throughout Europe, models belonging to classes N, SN or ST can be successfully used. However, for consumers looking for more functional options, double-labeled refrigerators can also be considered.
Double labeled models: refrigerator climate classes SN, ST and others
Not all models of refrigerators are marked with only one letter. Often, a user who chooses a technique for himself meets the marks SN-ST, SN-N-ST on it. Products with this designation are double climate category refrigerators. However, they are not universal devices. In fact, such products are simply equipped with an additional insulating layer. But they are produced by almost all modern manufacturers. The most versatile are Whirlpool’s WBC 3534 A+NFCX, WTC 3746 A+NFCX, and INDESIT NBS 18 and INDESIT BIAA (SN-ST class). They operate in the temperature range +16°С..+43°С degrees.
In operation, they often consume a larger amount of electricity, often form an increased amount of condensate. In addition, such models cost their owners an order of magnitude more expensive than those produced with conventional markings.
Domestic units, which are also suitable for operation in our climatic conditions, have a different marking – UHL (moderately cold) or O (general climatic). They work well at low temperatures, can be installed even in poorly heated rooms, and the power consumption is also low.
Today, the industry offers customers many versions of devices with different markings for the climate class. It is on it that you should pay attention first of all, choosing a model clearly for your operating conditions. This approach will ensure high efficiency of the device and a long service life.
