No Frost: what is it in the refrigerator, pros and cons

Rating of the best refrigerators with the No Frost system

What is No Frost technology

Refrigerators with the No Frost function can operate without ice, frost and snow appearing on the walls. It's all about the fans with which the unit's system is equipped. Due to high humidity, water droplets freeze and turn into ice, which remains on the walls of the chambers.

Fans in the No Frost system supply cold air to the chambers and dry the resulting drops. Thanks to this, there is no frost or ice on the walls.

Full No Frost

In fact, the main difference between the system is only the degree to which know frost technology is used. Such refrigerators have autonomous evaporator defrosting systems in the low-temperature and medium-temperature compartments.

The principle of operation of the No Frost system

Function But Frost in the refrigerator and what it is is now a little clear, it remains to figure out how it works. Since cold air constantly circulates in the chambers, defrosting occurs automatically.

The air is supplied by fans and then enters the evaporator. Also, a small amount of moisture escapes to the evaporator, which is converted into frost. But he doesn't stay there long. The heater turns on and turns the thin ice into water.

The resulting water enters a special tray under the refrigerator and then evaporates.

In order for cold air to distribute evenly throughout the chambers, fans must operate in constant mode.

Low Frost, No Frost or drip system: what is their difference

The drip defrosting system has long been known to users. In this case, all the resulting water flows down the walls into the tray. Sometimes such a system is also called “crying”.

Now what is No Frost in the refrigerator and what is the difference from the drip system. Several fans distribute cold air throughout all areas of the chambers. The temperature regime is equalized in all corners and the products are cooled evenly. Air, with a small amount of moisture, leaves the walls and remains on the evaporator.

Then the heating element turns on. As a result, the resulting ice melts, the water goes into a special container and then evaporates. At the same time, the walls of the chambers remain dry.

Low Frost system is the location of the evaporator throughout the entire area of ​​the freezer. Ice forms here in minute quantities, so defrosting is done much faster.

There is also the concept of Frost Free . Frost Free, Full No Frost - all these are types of cooling systems that may differ slightly. They are found in almost all designs of global refrigerator brands (Nord, Stinol, Indesit).

The Low Frost function is found only in freezing units.

Frost Free

Frost Free technology combines drip and know frost systems. In the cooling chamber, the temperature is maintained by a drip system, and in the freezer, No Frost is implemented. The cameras do not communicate with each other in any way.

Such devices always have a compressor, although there are exceptions.

Myths about refrigerators with No Frost

Users always treat anything new with a little suspicion. This gives rise to some controversial issues regarding this or that technology. Below we will look at some of the myths circulating around refrigerators with the No Frost system.

But Frost consumes more electricity

This is not entirely true. Even if such refrigerators have high energy consumption, the difference with other models is small. You can also pay attention to new, energy-saving modifications.

There are no No Frosts with large chambers

Since fans built into the chamber actually take up a lot of space, the internal area will be slightly smaller. But there are tall and wide models to choose from, the internal volume of which is much larger.

Refrigerators of this system are very noisy

Only the most inexpensive models with No Frost make a lot of noise. If you want silence, you can choose a more modern “non-freezing” refrigerator with sound insulation.

Health risks of No Frost and other myths

There is an opinion that the freon contained in such units is highly toxic and harmful to health. It must be said right away that such refrigerators contain exactly the same refrigerant as in other units.

The freon is closed quite hermetically and there is no contact with air. A leak can only occur if the pipeline has cracked or burst. And even if the refrigerant leaks, nothing bad will happen. This gas is heavier than air and will not enter the human lungs.

Some housewives believe that due to constantly circulating air currents, food can dry out. There is a lot of controversy about this, because it is better not to leave food open. Well, if closed, the food will not dry out. Vegetables and fruits benefit from such cold airflow. No moisture means no rotting process.

No Frost does not require defrosting at all

Although a refrigerator with a No Frost system is considered “non-freezing”, it is still recommended to defrost it 2-3 times a year. The fact is that here, too, you may not close the door completely. The seals also wear out, as in other refrigeration units.

All this leads to the fact that the chamber begins to cool faster than usual and the ice layer on the evaporator does not have time to thaw. For the same reason, you should not overload the refrigerator with food.

Understanding the concepts

Modern refrigeration equipment is represented not only by different types of systems (static or No Frost), but also by different cooling methods. No Frost has several types of cooling device, each of them has a different operating principle.

Differences between Total No Frost and No Frost

With the Total No Frost system, the freezing chamber and the main compartment are autonomous devices placed in a single housing. Each of them is equipped with a personal cooling circuit, fan, compressor. Cold air circulates between them through special openings. If the compressor in the freezer fails, this will not affect the operation of the main compartment in any way.

The Total No Frost function is a guarantee of energy efficiency, high power of the device and high-quality storage of products. It prevents the formation of mold and unpleasant odors and does not require defrosting the refrigerator.

The difference between Total No Frost and No Frost is also that the latter operates according to the rule of dry cooling, and therefore, uncovered food can dry out.

Difference between Neofrost and No Frost

“No Frost” is such a variety of cooling systems that every buyer can find his ideal option. One of the newest technologies is Neofrost. Its peculiarity is that the main chamber and the freezing compartment are equipped with two separate cooling systems.

"Neo Frost" allows you to maintain an optimal climate in the refrigerator, maintain up to 90% humidity, which means you do not overdry food and prolong its freshness as much as possible. Food cools much faster, and odors do not mix between compartments. The technology was developed by the manufacturer Beko. According to experts, it is the future of refrigeration equipment.

Neofrost differs from No Frost in the autonomy of the cooling devices of the freezer and main chambers. It retains moisture as much as possible, ensuring high-quality storage of food. If you choose between these two technologies, then the advantages are more on the side of Neo Frost.

Low Frost or No Frost: what to choose

No Frost defrosting is a process that does not require manual work. Ice does not appear inside the refrigerator chambers, and the ice that forms on the compressor or pipes quickly melts due to the operation of the heating element.

With Low Frost you still have to defrost the freezer. The evaporator is located inside the freezer compartment, retaining moisture well and maintaining the temperature at the same level. But ice, although a thin layer, gradually forms inside the refrigerator. Therefore, sometimes it needs to be defrosted manually. Compared to older models, defrosting a freezer with the Low Frost function is much faster and more convenient. This function is installed only in the freezing compartment; it does not apply to the main compartment.

When choosing between these two cooling devices, consumers give preference to No Frost, although the price of equipment with Low Frost is usually lower.

Differences between the drip system and No Frost

No Frost in the refrigerator is an excellent technical solution when there is no time or no desire to clean and defrost. The system works so that the temperature distribution is uniform across all compartments, thereby prolonging the freshness of all products.

Despite numerous laudatory videos and reviews regarding No Frost, arguing about what is better, No Frost or a drip refrigerator, is to some extent a mistake. Both cooling systems have undeniable pros and cons.

The drip device works completely differently than No Frost. The back panel of the chamber is actually the evaporator, where condensation forms. Over time, there is too much moisture, it goes into the pan, where it also gradually evaporates. Despite the cyclical nature of the process, if the internal surfaces are not dried in time, the drain becomes clogged. Then liquid appears in the food compartments. Drip models require frequent defrosting, at least twice a year.

Advantages of drip technology:

• the chambers are more spacious than those of devices with No Frost;
• silent operation;
• low power consumption.

The disadvantages include:

• uneven temperature distribution: the bottom is colder than the top;
• defrosting of the refrigerator is required;
• moisture on the back panel freezes if the settings are incorrect;
• If you leave the door open for a long time, it will take a lot of time for the chamber to cool down.

“No Frost” is a cooling device that simultaneously facilitates the work of housewives and takes care of long-term storage of products. There is also slight condensation on the back panel of such a device. This nuisance is directly dependent on how long the doors were open and on the high level of moisture in the food.

No Frost, Frost Free and Full no Frost

We have already figured out the No Frost system in the refrigerator (what it is and how it works). It remains to understand what “Full No Frost” and “Frost Free” mean.

Full No Frost means the same as "Total No Frost". This is a commercial move by the manufacturer - to use 2 different names in relation to one technical solution.

Frost Free involves a combination of two types of cooling in the refrigerator. The freezer can be equipped with No Frost, and the main chamber with a dynamic system. This combination allows you to retain sufficient moisture for food and avoid defrosting equipment.

The No Frost system is a solution to those annoying problems that old refrigerators had. With it, you can forget about snow-covered walls in cells and many hours of defrosting equipment.

How to care for a unit with such a system

Despite all the assurances that No Frost refrigerators do not need to be defrosted, this is not true. Defrosting is present here, only in automatic mode. But even with such a system, the refrigerator must be cleaned to get rid of bacteria inside the unit. This is done as follows:

1. Unplug the refrigerator.
2. Remove all food from the chambers.
3. Wait until the temperature in the chambers reaches room temperature.
4. Remove shelves and drawers, then wash them in warm water. Then wipe with a soft and dry cloth.
5. Wipe the refrigerator compartment with a solution of water and baking soda, in a ratio of 1 liter. water and 1 tablespoon of soda.
6. After drying, place the drawers and shelves in their places.
7. Connect the unit to the network, not forgetting to set the thermostat to the specified value.

Total No Frost

Total is an innovative defrosting system first introduced by LG. It is based on the technology of a specific Multi-Air Flow air flow distribution pattern. This allows you to reduce the freezing time several times. What it gives are the following benefits:

• Improving the taste of frozen foods.
• Energy saving.
• Limiting the formation of mold and unpleasant odors inside the refrigerator.

The coolers are located so that cold flows reach even the most inaccessible places in the chamber. This technology is premium, which is why such models are the most expensive.

The Multi-Air Flow system distributes air flow equally in all chambers.

Possible faults

Even with advanced refrigerators, troubles and even serious breakdowns occur.

If water has accumulated under the refrigerator or it is too noisy, this is a signal of a problem. If there is a loud noise, the compressor is worn out. The reason for the incorrect operation of the refrigeration unit may be a malfunction of the thermostat or temperature sensor.

Loosely closed doors or worn seals also interfere with the normal operation of the refrigerator. A freon leak or interruption in the functioning of the evaporator cannot be ruled out. With some modifications, the drainage hole may become clogged.

Refrigerator drip defrosting system and No Frost - which is better: comparison, pros and cons

When choosing a refrigerator, the question often arises, which system is better to choose. We have compiled a table comparing both systems.

Advantages and disadvantages of refrigerators with the No Frost system

Even perfect technology has its pros and cons, and No Frost is no exception. First, about the advantages :

1. There is no need to constantly monitor the unit. You can defrost it a couple of times a year, depending on the condition, and then just keep an eye on the cleanliness inside.
2. There is no accumulation of condensation.
3. Rapid cooling of products.
4. The temperature is distributed evenly across all sections. It is possible to set up a separate program for the freshness zone.
5. The “No Frost” function is applicable to both freezers and refrigerators.

Now a little about the cons :

1. Small volume of chambers due to built-in fans.
2. High power consumption.
3. Noisy in operation, but there are models with sound insulation.
4. High cost compared to drip analogues.

Useful tips

Additional Information. What to look for when choosing a refrigerator: expert opinion.

• Usually there are stickers on the doors that indicate the noise level emitted by the equipment. The optimal noise level should not exceed 40 decibels. If the value is higher, this indicates poor quality of sound insulation in the device.
• Economical. Models with increased energy efficiency are preferred. They are class A++. If a cheap model consumes a lot of electricity, then its purchase is not worth it. At the same time, many models in the middle and higher price categories consume much less electricity, saving the family budget.
• The presence of two fans will allow you to change the temperature in different compartments of the chamber. This makes it possible to create a “freshness zone” for storing fruits and vegetables for a longer period.
• Please read the instructions carefully. Some budget models do not defrost automatically. Therefore, this should be done at least once a year.
• It is advisable that the device be equipped with a special compartment where products can be stored without packaging.
• Pay attention to the internal volume of the chambers. From the outside, the refrigerator appears larger than it actually is.
• Number of compressors and their type. If there are any. If a compressor breaks down, it cannot be repaired and can only be replaced.
• Additional functions. Expensive models are equipped with a number of additional functions, including a door lock. This is very important for families with small children.
• Color, design, configuration. The stores offer a wide range of different models. They differ in color, internal arrangement of shelves, chamber volume, etc.

When purchasing a refrigerator, you need to carefully read the instructions and functions.
