No Frost technology has recently entered the arsenal of household refrigerators, but has already managed to earn the trust of users. Conventional refrigerators in which blocks of ice freeze in the freezer are less and less common in households. What users No Frost refrigerators are so fond of, we’ll talk in this article.
Let's start with the device. Classical refrigerators Nou Frost, or rather it is more correct to call them Full No-Frost or Total No-Frost, have one evaporator in which a heating element is built in, and one motor. The evaporator is in the freezer and cools both the freezer and the refrigerator compartment. The cooling chamber is cooled by a fan. He drives cold air from the evaporator through special channels into the refrigerator. The air supply is regulated by a special damper, which closes when the set temperature is reached in the refrigerator.
During cooling, frost forms on the evaporator. As soon as the temperature in it drops to too low, the heater switches on by the defrost sensor signal. The frost on the evaporator, which appeared during the period of operation of the refrigerator, thaws, and the moisture formed flows through a special channel into the condensate bath located on or near the compressor. Then, the cycle repeats.
What are the advantages and disadvantages of No-Frost refrigerators compared to conventional ones?
Pros of Refrigerators with Know Frost
- No need to defrost. This is the main advantage of the refrigerator with No Frost. Disable it only to wash.
- The same temperature at all levels. Even blowing of the fan provides the minimum temperature difference on the shelves of the refrigerator.
- Quick freeze food. Foods freeze quickly, especially when using the Super Freeze function.
Cons of refrigerators No—Frost
- Price. As a rule, refrigerators with automatic defrosting of the Nou Frost evaporator are more expensive than usual.
- More noisy. In addition to the motor, as in conventional refrigerators, the noise comes from the Nou Frost fan. Therefore, some users are outraged at first by the loud operation of the fan, but then they get used to it.
- Dries foods. Constantly circulating in the refrigerator air takes moisture from the surface of the products, and they slightly dry. In any case, always cover something with products or wrap them, and then you simply will not notice this drawback. And exactly the same recommendations apply to conventional refrigerators.
In our opinion, the advantages of refrigerators with Nou Frost outweigh the cons, but the decision is what kind of refrigerator to buy for you.
