What is it - the "No frost" system in the refrigerator: differences from standard models
First, let's figure out how the heroes of our review differ from their traditional "brothers". The device of a standard refrigerator implies the presence of an evaporator responsible for the timely transformation of water into a liquid or gaseous state. When manufacturing devices with "Know Frost", fans are added to the design in the refrigerator and / or freezer compartment. Also, the evaporator itself in such devices is not mated with the cooling chambers, it is displayed in a separate section. Also in the construct there is a special container for collecting water (we will talk about its function later). The described improvements lead to an increase in the size of the product, but any advantage has its own "downside". Otherwise, such devices are no different from classical solutions.
How the No frost defrosting system works - how it does it
With structural innovations, everything is clear. But how can such a technique avoid the need for constant defrosting and cleaning? The answer is simple - the fans installed in the case blow the back wall of the chamber from time to time. This facilitates the evaporation of excess water droplets, as well as its competent circulation in the system.
In Nou Frost refrigerators, water still turns into ice, this happens on the surface of the cooling system. But here the cooler also plays a role. He periodically blows hot air, thereby melting areas with frost. The resulting moisture eventually enters a special container located under the compressor. After a certain period of time, this liquid again takes part in the cooling processes.
NOTE!
In addition to combating the formation of an ice crust inside the refrigerator, Nou Frost allows you to effectively and efficiently distribute the cold inside the appliance, thereby eliminating the need to distribute food to the "zones cold ".
Varieties of Know Frost technologies in refrigerators: "Frost free" or "Total no frost" - what is it
If drip thawing does not have any subdivisions into classes, then with "No frost" everything is somewhat more complicated - there are several slightly different types of equipment. However, if you want to choose a truly functional model, you need to know the difference and advantages of the modern "Neo Frost" or the all-encompassing "Full no frost".
"Frost free" - entry level for supporters of "classics"
This technology is the least functional and still exists only because of the low prices for finished products, compared to competitors. In models with a similar system, Nou Frost is used in the freezer and drip defrosting in the refrigerator compartment. This way you save time cleaning the freezer, but the main space will need regular defrosting anyway.
"Full no frost" is a balanced and popular option
Unlike the previous solution, this technology provides frost protection in both sections of the refrigerator. Most of the popular models are equipped with this particular modification. With it, you can always keep food fresh, saving a lot of time for important things and hobbies.
"Total no frost" - even more possibilities!
This designation can often be found in "No frost" refrigerators from the LG brand. In principle, this solution is not much different from the previous version. The main difference is the presence of additional process holes to distribute the flow air on several paths and thus further reduce the risk of icing on parts of the refrigerator.
"Neo Frost" - a fresh take on food refrigeration from Beko
Turkish firm Beko has also decided to contribute to the development of food refrigeration equipment. Through the efforts of their developers, another system was born - "Neo Frost". All the advantages of the Full modification are preserved in such refrigerators, but the complete isolation of the compartments among themselves has become a distinctive feature. As a result, this leads to faster freezing of food of various categories.
Advantages and disadvantages of Know Frost technology - an objective assessment of experts
Like any household appliance, the heroes of our review have both strengths and weaknesses. You definitely need to know about them before starting the purchase, because for someone the advantages may be insignificant, and the disadvantages completely neutralize all the benefits of the device.
| Dignity | Flaws |
| There is no need to defrost the compartments for cleaning and correct operation of the device. | Increased energy consumption due to a more complex cooling system and more operating elements. |
| The even distribution of air and humidity allows you not to lay out food in the "cold zones". | Compared to traditional versions, models with "Know Frost" are larger and cumbersome. |
| Good level of freezing of any type of food in less time. | Such a phenomenon as "winding" is more common than with standard solutions. |
| Quick cleaning of the inner surface from dirt and accidentally formed ice. | Compressor and fan operating noise exceeds competitors' performance. |
NOTE!
Sometimes manufacturers add the function of air purification to refrigeration equipment (with an ionizer or other methods). This allows you to keep food fresh and taste even longer, as well as prevent unpleasant odors. But keep in mind - you will have to pay an even more substantial amount for this pleasure!
Drip defrosting system or "No frost" - which modification is better to choose
Another important point that must be taken into account is when it is worth choosing a model with the classic cooling scheme, and in which "Know Frost" will be the best assistant for preserving your favorite products fresh? Drip defrost is suitable in the following situations:
- You are already familiar with temperature distribution by zones in the refrigerator and have long been accustomed to arranging food in accordance with the rules.
- You rarely use the quick freeze function and do not cook various foods for future use.
- You live in conditions of low air humidity.
- You are not ready to pay a lot of money (there is practically no budget segment among the models with "No ftost").
"Know frost" refrigerators will be relevant under the following circumstances:
- You constantly prepare vegetables, fruits, berries for consumption in late autumn, winter or early spring.
- You don't want to waste time and effort defrosting the chambers and cleaning them monthly.
- You live in regions with high humidity and hot climate.
- You have no desire to memorize temperature zones and arrange food in accordance with zoning.
Let's talk about cleanliness: what kind of care does Know Frost refrigerator require?
Although device manufacturers claim that their products do not require additional procedures, cleaning the inner surface should not be ignored. Moreover, a small layer of ice will still be present, interfering with the correct operation of the device. And the beneficial properties of food will gradually decrease, due to the formation of various microorganisms. The cleaning procedure for "No frost" refrigerators is approximately the same as for a conventional "drip" apparatus.
| P / p No. | Description of action | Illustration |
| 1 | We turn off our equipment by removing the plug from the socket. |  |
| 2 | We take out products stored there from all chambers. |  |
| 3 | We take out all removable shelves and pallets. |  |
| 4 | We make a mixture of water and detergent (or soda) in any convenient container and clean the inner surface of dirt. |  |
| 5 | We wash dirty trays and shelves in the bathroom using the solution described in the previous paragraph. |  |
| 6 | We return all the elements to their places, reconnect the refrigerator to the network. |  |
As you can see, there is nothing difficult in caring for the device. And if you consider that such manipulations need to be carried out only once every six months, you can save a lot of time!
