How does the refrigerator with the system "know frost"

The advent of the No Frost system (fro fro) has become a real boon for users of refrigeration devices and freezers. Many people understand it literally, without turning off the unit from the network since its appearance in the house - and this is fundamentally wrong. It will be interesting for the present and future owners of such equipment to know how the “frost know-how” refrigerator works, especially since there are plenty of nuances here.

What is the No Frost technology

First of all, it’s worth finding out why frost (and then ice) forms on the walls of the apparatus. There are several reasons for this:

• high condensate;
• unpackaged appropriately liquid products (increased humidity);
• long work of equipment (for years) without defrosting.

With Noufrost everything is different. In literal translation, the name of this system means "no frost." And, indeed, there is no frost and snow buildup inside the refrigerator itself. This is not a magic, but a feature of the device.

1. Inside the apparatus blow special fansthat chase cold air around the device. This ensures constant air circulation in the closed space of the device.
2. Between the fridge and freezer compartments installed branch with evaporator.
3. On the one hand, the air enters the evaporator, where it cools and leaves at the opposite side (at that time frost forms in the compartment). Periodically, the compressor "stops" - at this time, the fluid thawed from the frost is removed from the device in a special tray.

It is thanks to this well-thought-out system that frost does not appear on the walls of the apparatus, and, consequently, condensate does not appear.

Moreover, the system is used "anti-frost" and in freezers, and in the refrigerated cabinets themselves.

The advantages of such units are as follows:

• rapid cooling of the products placed in them;
• minimum temperature difference between the whole chamber space;
• highly fast freezing products;
• rapid recovery of temperature inside the device, even after frequent opening and closing the door technology.

Not without flaws, which also need to be prepared:

• at similar devices smaller capacity (most of the internal space is occupied by the block from No Frost;
• increased power consumption;
• perceptible noise at work;
• airborne products;
• high price similar technology.

Built-in refrigerators with the know frost system

On the modern market there are two types of arrangement of such units - stand-alone and recessed options. The most interesting are the second ones, since they fit perfectly into any interior: they can be identified under the worktop, decorated with panels under the kitchen interior or put in any other place convenient for the user.

Embedded appliances save space in any kitchen, which is important for small rooms.Is it possible to “hide” in this way the said refrigerator, considering the peculiarities of its work? Manufacturers assure that yes.

When choosing a built-in refrigeration unit, the following parameters should be considered:

• compact size, suitable for the selected niche;
• easy operation and maintenance;
• optimal number of options;
• ergonomic camera device;
• the freezer which is not demanding a defrosting;
• acceptable cost.

Installation also implies compliance with some mandatory requirements.

1. There must be good ventilation and moderate humidity in the room itself.
2. To avoid overheating, from the walls to the device itself should be left at least 3-5 cm on the side and 10 cm above. The back wall does not overheat.
3. There should be no heat sources nearby.

Overview of popular built-in models with the possibility of freezers

Will give popularity rating of embedded refrigerators with the know frost system.

1. Users in one voice give preference two-chamber Hotpoint Ariston BCB 33 A F (dimensions 54 × 18.5 × 54.8 cm with a total volume of 274 liters). In terms of price, quality and capabilities, such a device turns out to be the undisputed leader.Here, only the necessary options, including Active Oxygen, which ensures the preservation of the original freshness of food through ozonation, the SuperCool function (fast cooling even with maximum camera load), SuperFreeze (very fast freezing). The hosts are captivated by the easy installation of the unit and maximum efficient energy saving.

2. The volume of the built-in German unit Liebherr ICUNS 3314 is designed for 262 liters, and its dimensions are 54x55 × 185 Along with the “know frost” can be identified super freeze. However, users are not entirely satisfied with noise and vibration, which the device reproduces during operation.

3. Siemens KI39FP60 with built-in case type was named one of the best models of the “know-frost” of the past 2016. The size does not differ much from the previous ones (56x55x177 cm), and among the functions there are also possibilities of supercooling, super-freezing and temperature indication. But not only that - in this model energy class A ++ (which is higher than the previous two options). It means that the concern of the developers about the environment is traced here. In addition, the technique is really, easy and pleasant to manage with one light touch using the touchControl system.

Among other brands, interesting built-in models with No Frost can be found in Atlant, Bosch, Samsung, LG, BEKO, Siemens, Mitsubishi.

How to care for the unit with such a system

The technique is used to store food - it is logical to assume that various smells will heat up in such a place. Starts very fast reproduction of bacteria and microorganisms. And this is not to mention the spots - when interacting with food, they are inevitable. Even on the walls of the freezer: this often happens when the user forgets to close the door to the end. All these and other reasons make it relevant to clean and ventilate the unit at least once a year and a half.

General requirements for preventive maintenance for a refrigerator with No Frost

Defrosting is, of course, a conditional term for the care of such devices, just such a procedure in the presence of “bezineyuyu” technology should be done much less often than with conventional units. The most complete information about working with refrigerators that have such a system, of course, is contained in the instructions for each model. General recommendations for all will be as follows.

1. It is not necessary to plan an event in a strong heat - such a load will be a strong challenge for the compressor.
2. Should know in advance one or two cooling circuits in a refrigerator. In the latter case, only one camera is thawed. In the first embodiment, the technology is completely disconnected from the network.
3. You can speed up the process with the usual hair dryer. This “know-how” will quickly remove excess moisture and bring the temperature inside the device to room temperature in a quick time.
4. In the case when there is no hair dryer, the device is simply left off for two hours.
5. The unit should be washed completely inside and out. Do not ignore the back wall, because it is on it that the most dust accumulates.
6. Do not use sharp objects (for example, knives) for scraping ice - thus there is a risk of damaging the internal walls.
7. You can not turn off and immediately turn on the refrigerator - from this time must pass at least 12 hours (the optimal time is a day). It's all about high pressure, which is maintained in a motor condenser. During shutdown, it naturally falls. Ideally, this should occur gradually, but it is precisely with repeated sharp switching it will increase again, which leads to large loads of the motor and is able to break it.

Nou Frost refrigerator cleaning procedure

For washing the unit inside it is forbidden to use chemical detergents: there is a risk that their residues will settle on food. Outside are allowed to use any non-abrasive substancesas long as they do not damage the surface. Sufficient mixture of soda and water in the proportions of 2/3 tablespoons of powder to 0.5 liters of liquid to clean the interior well with cotton buds. The procedure itself will be carried out according to the following algorithm.

1. The device is turned off from the network, after which it gets all the products.
2. First cleaned air vents - they are processed with cotton buds moistened in a mixture. This should be done without loosening and dismantling the ventilation panels (this may violate the warranty on the equipment).
3. Shelves, drawers, pockets and doors are washed with the same solution.
4. Also processed and rubber sealsIn which very often there is a hotbed of microbes.
5. The last step is to wipe all the details with a simple damp cloth.
6. You can air out the refrigerator a bit, leaving its doors open.
7. After the product layout, the unit can be plugged into the outlet.

Preventive measures to extend the operation of refrigerators with No Frost

Any equipment will last longer with proper care. There are a few simple rules that the device owner can follow:

• it is recommended that the equipment itself be placed away from sunlight and stove;
• all contamination in the device is removed immediately - after drying it will be more difficult to do;
• do not place food hot;
• it is best to store products in the appropriate containers or packages.

Who should buy this technique

Of course, the emergence of such refrigerators causes the desire to purchase it for their kitchen. But it turns out that it does not always make sense to do this.

1. AT dry regions problems with excessive moisture inside the refrigerator will be much less, and, therefore, there will be no question of excessive frost formation.
2. No Frost is not suitable for those who are used to place products in different temperature zones of the device.
3. Those who do not often look into the freezer and put there products in large volumes, also do not need a quick freeze.

In any case, the refrigerator should be chosen based on its own technical requirements. And whether it will be with No Frost or not, have additional functions or do without them,built into the furniture or stand alone - each user decides for himself.
