The place of honor in the kitchen, of course, is occupied by the refrigerator. And he will be discussed in today's article. In particular, we will talk about such a thing as No Frost in the refrigerator. What it is? How is it designed and what are its advantages and disadvantages? Below we will talk in detail about all this.

What is No Frost Technology?

Know Frost technology - how does it work?

Modern models are so advanced that they practically do not require care and concern. A few decades ago, women spent at least half of their day off every month to perform a ritual called "defrosting the refrigerator." Today, many young housewives are not at all familiar with this concept. This was made possible thanks to new developments in the field of cooling systems.

In modern units, two fundamentally different cooling technologies are used: drip and Nou Frost. The first is much more common and is already familiar. But about the second, many questions still arise.

According to the promises of manufacturers, No Frost refrigerators do not need defrosting at all. The fact is that the frost on the walls of the refrigerator occurs due to increased humidity inside the chamber. Water droplets freeze and eventually turn into an ice crust.

The refrigerator with the No Frost system works without the formation of frost and ice. By the way, the very name of the technology speaks about this. “Nou frost” literally means “without frost / frost.” This effect is achieved by incorporating several fans into the system. Streams of cold air blow around the inner walls of the chamber and drain the droplets of moisture formed. Thus, hoarfrost practically does not form on the walls, which means that there is simply nowhere to take a snow hat from.

In refrigerators equipped with No Frost technology, the evaporator is moved outside the chamber and is forced to blow using one or more coolers. Hoarfrost in such units is still formed, but not in the chamber, but on the tubes and fins of the cooling system. From time to time, a special heater is turned on, which independently defrosts the system. The liquid is collected in a pan hidden behind the compressor and the process starts again.

Although dry-frozen refrigerators have been specifically designed for use in countries with a fairly humid climate, they are also widespread in our region.

Pros and cons of the No Frost system

The popularity of the “non-freezing” system is growing every day. But the traditional drip system is also not losing ground. What are the advantages and disadvantages of the “no frost” system?

Positive points

Do not require close attention of the hostess. It is enough to defrost it once, at most twice a year. The rest of the time, you just need to wipe the shelves and doors.
You will never see frost or droplets of condensation on the walls of the chamber. It will never flow or cry.
A plus is also the cooling rate of products. Refrigerators with "wind" cooling perform the task much faster.
They have the same temperature in all compartments. An exception may be only a separately programmable zone of freshness.
No Frost is suitable for both the cooling chamber and the freezer compartment.
Very quickly restore the set temperature after opening / closing the door.
In some models there is a function of quick dry freezing, which is very popular with many housewives.

Negative sides

Due to the built-in fans supplying cold air to the chamber, the real internal volume of such models is slightly less than it might seem at first glance.
For the same reason, But Frost consumes a bit more electricity than their drip comrades.
It features a slightly more noisy work. However, the most modern models are equipped with a system of enhanced sound insulation, so that the increased number of decibels is almost imperceptible.
The air circulating in the chamber of the No Frost refrigerator drains not only the walls, but also the products. To prevent this effect, the products should be packed in plastic containers or wrapped with cling film.
Probably the biggest drawback of such refrigerators is the price, a little higher than that of drop counterparts.

What is Frost Free System?

When buying a refrigerator, some housewives come across a name such as Frost Free or Fresh Frost Free. What does this name mean and how do these refrigerators differ from the classic Nou Frost.

Frost refrigerators are a combined option. The refrigerating compartment and the freezer with this technology are separated from each other, however, they work from one compressor.

The freezer is most often located downstairs and operates on the Nou Frost system. But in the upper chamber, a drip cooling system is supposed. The temperature in the cooling chamber of such a refrigerator varies depending on the height and ranges from +5 to +8 degrees Celsius. Humidity is maintained at 70–80.

Full no frost

Another fairly new name for an unenlightened buyer is the Full Know Frost system. Here we are talking about the presence of two completely separate systems operating on the principle of No Frost. Each of the systems has its own compressor, evaporator, coolers and individually closed circuit.

Roughly speaking, these are two separate units - a refrigerator and a freezer, set one on top of the other. One of the advantages of such a system is that if, for example, your compressor in the freezer breaks down, the medium-temperature cooling chamber will continue to work as if nothing had happened.

Total no frost

Total No Frost technology in the refrigerator

This system is almost identical to the previous one and differs, in fact, only in name. By the way, these systems have one more important feature. Refrigerators with Full No Frost and Total No Frost refrigeration most often have additional circulation channels between the freezer and the refrigerator compartment.

On the one hand, this allows you to maintain a more even and cooler temperature. But on the other hand, if you do not follow the rules of food storage, you run the risk of getting ice cubes for a cocktail that smell like garlic.

Should I buy a No Frost refrigerator

Of course, in the household appliance department you will most likely be offered just such a model.This is not surprising, because we have already found out that No Frost refrigerators are somewhat more expensive, and the salary of a sales manager most often makes up a percentage of the cost of goods. But perhaps you should pay attention to other models.

When choosing, you must take into account all the shortcomings indicated above, and decide whether they are really critical for you. A weighty argument in favor of acquiring a Nou Frost refrigerator or a mixed type can be a quick dry freeze system. If you like to harvest berries, fruits, and vegetables for the future, you simply won’t find such a system.

How to care for a unit with such a system

How to care for the refrigerator with the

Although manufacturers of refrigerators “without hoarfrost” promise that they will not have to defrost, they should not be trusted. It is absolutely necessary to completely defrost the refrigerator at least once or twice a year. And it's not about freezing frost or ice. You really will not see them. Cleaning should be done for hygiene reasons. The fact is that you thoroughly wash and destroy various bacteria and microbes in it, without disconnecting the refrigerator from the network, you will not succeed.

For those who have never washed a refrigerator in their life, we offer a small instruction on how to do it correctly:

Set the temperature control to the lowest (zero) position and disconnect from the mains.
Remove all food and wait until the temperature inside the chamber reaches room temperature.
Take out all the shelves and drawers and rinse them under a stream of warm (not hot!) Water.
Dry with a microfiber cloth or other non-lint cloth.
In warm water, dilute a certain amount of baking soda (1 tbsp. L. Without a slide per liter of water).
Wipe the inside of the refrigerator with a soft, clean cloth dampened with a solution. To clean particularly hard-to-reach places, grooves and crevices, you can use an old soft-bristled toothbrush.
After 15 minutes, wash the refrigerator again with cool, clean water without adding any agents, and then wipe with a dry, lint-free cloth.
When all the internal parts are completely dry, place the shelves and drawers inside.
Plug in the refrigerator, set the desired temperature, and put the food inside

As you can see, there is nothing complicated in the process. Now you know what Nou Frost is in the refrigerator and you will be able to make a qualified decision. Despite some rather minor flaws, the Nezamerzayka refrigerator is a very profitable and useful purchase.
