Refrigerator No Frost Pros and Cons

Which is better: drip refrigerator or no frost

For several years, the owners of the refrigerators break the spears in an attempt to answer the question: which cooling system to choose. drip or know.free. And one and the other have their pros and cons, both an impressive mythology has developed around both, both protect the refrigerator from terrible ice fur coats. Let’s try to figure it out.

In another affectionate called “crying”. The principle of operation: behind the back wall of the camera is a small device. evaporator. It distributes cooling over the entire surface of the wall, while condensate is formed due to the temperature difference-small droplets of water.

Drops flow down the grooves and fall into the pallet, from where they simply evaporate, and a thick “ice fur coat” does not appear in the refrigerator chamber. Only if the capacitor works “full” droplets can freeze into separate ice.

In this case, the rest of the refrigerator walls remain dry.

Advantages and disadvantages

Refrigerators with a drip cooling system have a number of really significant advantages:

• They are cheaper.
• They consume less electricity (about 30% compared to No Frost, it all depends on the model).
• A wide range of models.
• They work quietly, although there are noisy models, before buying it is worth reading reviews.
• Products do not need to be additionally packaged. They are much slower and do not “dry out”.
• They do not have a fan, as in the No Frost system, due to this camera more.

True, there are also disadvantages that can complicate your life and take a bunch of free time:

• The drip system works only in the refrigerator. The freezer will still be overgrown with ice.
• They will still have to defrost. You need to do this every few months. There are two reasons: remove the ice from the freezer and “remove” the frozen droplets of condensate from the back wall of the refrigerator.
• After defrosting, the unit will “return” to the desired temperatures for a long time.
• Temperature “migration”. The drip system (or rather, the evaporator) does not distribute the cold over the entire back wall perfectly evenly. The temperature of the lower part from the upper will differ by 7-8 s °.
• You can not clean hot dishes in the refrigerator. Because of them, a “fur coat” may form, the compressor will also receive additional load (if it is not powerful enough, it may break).

If you decide to buy a refrigerator with a drop system, be sure to read user reviews and technical passports of devices. So you will find out if the unit will be too noisy, how well it “freezes”, how often it breaks, how much electricity consumes and so on.

The principle of operation of the Knou Frost system

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

Air is supplied with fans and then enters the evaporator. A small amount of moisture, which is converted into hooks, also goes to the evaporator. But he does not linger there for long. The heater is turned on, which turns thin ice into water.

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

In order for cold air evenly diverges through the chambers, fans must operate in constant mode.

Comparison of the drip and know.the Frost system

Household manufacturers do not stop there, and seek to create more convenient and practical devices for their customers. The next improvement of the refrigerator was the No Frost system, which confidently claims leadership in the household refrigeration industry. Let’s compare both systems.

The principle of operation No Frost is similar to drip, cooling inside is achieved due to the injection of the refrigerant into the evaporator. But such a refrigerator is additionally equipped with a fan, which is responsible for the uniform distribution of temperatures inside the refrigerator. Due to the moving air, the ice on the walls of the chamber is almost not going, therefore, and you need to defrost less often. In addition, you will not hear the sound of falling drops, and the drainage system clogs many times less. However, such a system is technically more complicated, therefore, if you came across an unscrupulous manufacturer, then get ready for frequent and expensive repairs of your household appliance.

If you compare both the refrigerator systems among themselves, you can see both the advantages and disadvantages of each of them. If you are forced to choose between the drip system and No Frost, then consider the following factors.

• periodic cleaning of the drainage system;
• manual defrosting of freezers;
• The difference in temperature in the upper and lower parts of the chamber.
• minimum care during operation;
• uniform temperature distribution;
• lack of an ice layer on the walls of the camera;
• rapid recovery of low temperature after defrosting.

Compared to No Frost models, “crying” refrigerators are more powerful and spacious. you can choose a huge model for a large family and a built.in device for your kitchen furniture. And also, products in units with a drip system are not weathered due to constant air flows, which are pumped up by built-in fans in the No Frost devices. But you can simply carefully monitor the safety of the packages or wrap the foods with cling film. then the weathing will not happen.

As you can see, there is no obvious advantage of one system over another. your choice depends solely on your preferences and wishes. Before buying, it is worth reading the opinions of experts, pay attention to reviews and various ratings. However, the final choice should be based on the ratio of all the advantages and disadvantages of each specific model of the refrigerator.

What is the No Frost system

Refrigerators with the No Frost system appeared relatively recently and became powerful competitors to all other types. From English, the name of the system translates as “without hoarfrost”. If in the drip type of defrosting users can see at what stage the device is now located (there is an irrigation of the flowing water on the back wall), then these processes are hidden from the user in the know.toou Frost.

NO Frost refrigerators device

Refrigerators with a defrosting system of the know.free Frost have a slightly different set of key nodes. They are supplemented by a fan with an engine and heating.

The main nodes of refrigerators with the No Frost system:

• The evaporator taking heat and collecting moisture is located not in the rear panel of the camera, but behind it.
• Even the device of such a refrigerator includes many channels in the rear and side walls to transmit chilled air along the entire area of ​​the chamber.
• Since moisture is condensed not on the back wall, but only on the evaporator, the sewage is also included in the refrigerator design, also hidden in the refrigerator wall.
• Ten. ensuring thawing hoarfrost.

The principle of operation of the refrigerator with the NOU Frost system

What is the know.Frost system, it becomes clear after considering the principle of its work. Like other models, the main active substance is a refrigerant, compressed to a liquid state and absorbing heat from chambers. But the cold air is carried through the entire inner area thanks to one or more fans and the system of channels that ensure the passage of cold air flows.

Due to this, a uniform distribution of temperature occurs, regardless of which shelf is on the shelf. But what about moisture? She, being in the air, condenses on the coil of the evaporator hidden inside. Then, due to the timer with which the No Frost system is equipped, at a certain moment the heater is launched and the process of thawing occurs.

The water on the drain enters a special container installed on the compressor and evaporates outside. This gives constantly dry walls of the refrigerator chambers and regularly removes moisture from it.

How to care for a refrigerator with such a system

Although manufacturers of devices without “ice” promise that you do not have to defrost it, you should not take their word. Still, you should conduct defrosting at least once a year. And the point here is not at all in eliminating ice and hoarfrost. The device must be washed elementary to destroy all microbes and bacteria accumulated in it. And for this you will have to temporarily turn it off from the network, otherwise, due to a large load, it risks breaking.

Knou Frost refrigerators must be cleaned 1-2 times a month.

For those who have not yet encountered such a system, we suggest that they familiarize themselves with the basic rules for the care of the refrigerator No Frost. How to wash the refrigerator correctly:

• Disconnect from the network. Previously setting the temperature regime on 0.
• Take out all the contents. Wait until the temperature of the cameras becomes the same as in the room.
• Remove all shelves and boxes. Rinse them under a stream of cold or warm water, but in no case is hot.
• After you have washed everything, wipe all the details with a dry microfiber. It is possible with another fabric, the main thing is that there is no pile on it.
• The internal walls of the chambers are best washed with soda solution, in the proportions of 1st.l per 1 liter.
• For hard.to.reach places, a toothbrush with soft bristles is suitable.
• Leave the cameras for 15 minutes, and then rinse again with water at room temperature.
• Place all the details back only when they are completely dried up.
• Now you can turn on the refrigerator. Когда в камерах установится оптимальный температурный режим, поместите туда все продукты.

There are no difficulties in the process of washing the refrigerator. The main thing is to do everything according to the instructions, so as not to spoil the device.

A wet cloth or sponge is suitable for washing the refrigerator.

Advantages and disadvantages

The indisputable advantages of refrigerators with No Frost:

• lack of ice on the walls, details of the case;
• dryness and purity inside;
• uniform temperature distribution in compartments;
• rapid restoration of the temperature regime after closing/opening the door;
• forced ventilation, so the products remain fresh for a long time;
• Dry freezing function in some models of freezers with No Frost.
• Due to the presence of fans, some models of refrigerators with know.how technology Frost are noisy, however, manufacturers provide high.quality soundproofing;
• more energy consumption;
• the internal volume is slightly smaller than that of drip analogues;
• Forced ventilation dries and “bent” products. The use of hermetic containers or food film solves the problem;
• This technique is more expensive than “crying” models.

Useful tips

What to pay attention to when choosing a refrigerator: expert opinion

Typically, there are stickers on the doors that indicate the level of noise published by the technique. The value of the optimal level of noise should not exceed 40 decibels. If the value is greater, it says this poor quality of sound insulation in the apparatus. Economy. Models with increased energy efficiency are preferred. They have class A. If the cheap model consumes a lot of electricity, then its purchase does not justify itself. At the same time, many models of the middle and highest price category consume much less electricity, saving the family budget. The presence of two fans will change the temperature in different compartments of the camera. This makes it possible to create a “freshness zone” for storing fruits and vegetables for a longer period. Read the instructions carefully. Some budget models are not defrosting automatically

Therefore, this must be done at least once a year. It is desirable that the device is equipped with a special compartment where products can be stored without packaging. Pay attention to the internal volume of cameras. Outside, the refrigerator seems more than it is actually. The number of compressors and their variety

If there are any. When damage, the compressor is not subject to repair, and it can only be replaced. Additional functions. Dear models are equipped with a number of additional functions, the number of which includes door blocking. This is very relevant for families with young children. Color, design, configuration. The stores present a wide range of various models. They are distinguished by color, the inner location of the shelves, the volume of chambers, etc.D.

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