Choosing a refrigerator: drip defrosting or No frost

Why do you need to defrost your refrigerator?

Regular defrosting is the key to long service life of the refrigerator. During operation, condensation forms on the walls of the appliance, gradually turning into a layer of ice, the thickness of which can reach up to 3 cm. In addition to the fact that ice reduces space and makes it difficult to access products, it can damage the functioning of the entire refrigerator. The more ice there is, the harder the compressor has to work to maintain the required temperature, as a result the motor is overloaded, parts wear out, and energy consumption increases.

Ice crust is a breeding ground for bacteria and a source of unpleasant odor because it contains food particles. When you open the refrigerator, the ice begins to melt, flooding the food stored in the chamber.

Ice accumulation can damage the refrigerator

The reasons for the formation of an “ice coat” lie in the ingress of warm air when the chamber door is opened, the storage of hot products, as well as malfunctions of the cooling system (refrigerant leaks, failure of the defrost sensor, malfunction of the thermostat, etc.).

To ensure uninterrupted operation of the refrigerator, it is necessary to defrost the chamber regularly. However, modern devices require minimal or no effort for this.

Currently, refrigerator defrosting systems can be divided into two main groups: the drip (crying) system and the No Frost system. The main difference between the latter is the absence of the need for defrosting - ice and condensation practically do not accumulate in such models. In addition, there are still devices with manual defrosting, the name of which speaks for itself. With such a system, the housewife will have to regularly turn off the refrigerator, waiting for the chamber to completely defrost.

Why manual defrosting of the freezer is a disadvantage

If the refrigerator compartment defrosts regularly on its own, then the freezer compartment has to be cleared of ice manually. Some types of refrigerators have two temperature controls: one for the freezer and one for the cooling panel. If you have just such a refrigerator, then you are in luck. You can defrost the freezer compartment separately from the second functional zone. If not, then we defrost the entire device.

Manual defrosting of the freezer must be done every 9 months for all owners of crying refrigerators.

If you do not defrost the refrigerator yourself, the device may fail and require expensive repairs.

This defrosting of the freezer is slightly different from freeing the refrigerator from ice.

And it is done as follows:

• Disconnect the unit from the network;
• We unload all the boxes with products;
• We substitute a special structure through which melt water will drain from the chamber;
• Leave the door open;
• After thawing, carefully wash the camera with warm water and soda;
• Carefully wipe all seals, rubber bands, fasteners, etc.;
• Remove remaining moisture;
• Let the surface inside the chamber dry;
• Loading clean boxes;
• Turn on the device.

Experts advise defrosting freezers in winter, when it is possible to take boxes of food to the balcony or other cold place.

Operating principles of No Frost and the drip system

Drip defrosting differs significantly from the operating principle of the No Frost system.

Drip defrosting

The drip system is the most common technology, the operating principle of which is to distribute a cold air flow along the back panel of the refrigerator. This task is performed by a special evaporator installed on the back side of the refrigeration compartment, as a result of which drops of water are formed, flowing into a certain container. When the compressor operates, the droplets freeze, forming a thin layer of ice. With the drip type, thawing occurs only in the refrigerator compartment, and the “freezer” will have to be thawed manually.

The drip system is also called “crying” because of the water drops flowing down the back wall

Video: a clear example of how a drip system works

No frost system

Unlike drip defrosting, the No frost technology, which translates as “no frost,” operates according to a different scheme. The cooling process is carried out by a compressor and evaporator built into the rear panel. However, the cooled air is distributed through its continuous supply by additional fans, which ensures uniform filling of the compartments. If the compressor stops working, the frost will begin to thaw and the condensate will evaporate. No Frost devices also produce condensate, but its amount is significantly less than its drip counterpart.

No frost system distributes cooled air evenly

In fact, the process of working, for example, a freezer looks like this. When the refrigerator is first connected, the compressor and fan are started. When the temperature drops to -10 °C, the ice automatically defrosts. When the ice finally thaws, the temperature of the chambers will begin to gradually increase. As soon as the temperature reaches +10 °C, the reverse freezing process will begin. Thus the process is repeated over and over again.

Additional features and functionality

Manufacturers can't come up with anything - refrigerators even come with a built-in TV. But besides exotic models with their unique bells and whistles, there are some very useful ones. If you have the opportunity to pay extra for comfort and ease of use... So here are the additional features a refrigerator may have:

• Super cooling freezer. A mode that is used when bulk loading products for freezing. Or if their temperature is high (in the summer, in the heat). The compressor turns on at full power to quickly reduce the temperature to +2°C. After it goes into normal operation.
• Super freezing of the refrigerator compartment. A similar mode, only the temperature is brought to -24°C.
• Antibacterial coating of the refrigerator compartment. The coating contains silver ions, which prevent the development of mold and pathogenic bacteria.
• Wine cabinet. A chamber with shelves for bottles and a special microclimate.
• Ice maker. There are two options - with a connection to a water supply or with a water tank.

  Additional capabilities of refrigerators are becoming wider

• Chilled water supply. Water is poured into a special reservoir in the refrigerator. Its temperature is maintained constantly, and through special tubes it is supplied to the recess on the outside of the door.
• Electronic control. Allows you to more accurately set operating modes and control the processes taking place in the refrigerator. The refrigerator status is displayed on a digital display.
• Temperature indicator. Helps control the temperature in the refrigerator compartments.
• Door open indication. If the refrigerator door remains open for a long time, a light or sound signal will sound.
• Reversible doors. In the standard version, the doors are made “right-handed”. In models with the possibility of reversing, they can open in the opposite direction.

For now, these are all the functions that can be found in commercially produced refrigerators.

Advantages and disadvantages of cooling systems

To illustrate the operation of the two types of defrosting, let’s look at the table.

Table: positive and negative aspects of cooling systems

Myths about the No Frost system

There is a lot of negative talk from potential consumers about refrigerators with the No Frost system. Let's consider the main ones:

1. Harmful to health. Many consumers claim that No Frost refrigerators use a “harmful” type of freon. It is not true. Refrigerators of this system operate on absolutely similar compressors and refrigerants as chambers with drip defrosting (R600a Isobutane).
2. Drying out food. The air circulation mode can indeed slightly oxidize the food. It is not surprising, because this technology was invented in a country with high climate humidity. Whole foods stay fresh much longer compared to drip-type devices. To avoid the oxidation process, it is enough to cover the contents with a lid or use cling film.

Video: story about the No Frost system

Compressor type: inverter or conventional

To understand which refrigerator to choose - with a conventional or inverter compressor - you need to understand how they differ.

One of the tasks is to choose the type of refrigerator compressor

Conventional compressor

How does a refrigerator with a conventional compressor work? The temperature you set is controlled by a sensor. When it drops by 1-2 degrees, the sensor sends a signal to turn on, the relay is activated, and the compressor turns on. It works until the temperature drops by the same 1-2 degrees. Then the cycle repeats.

In refrigerators with a conventional compressor, the temperature varies in the range of plus or minus two to four degrees, the compressor always operates at full power. Moreover, when it is turned on, overloads occur - starting currents are several times higher than operating currents. This overloads the system and interferes with the operation of power-sensitive equipment. In addition, these frequent starts lead to high energy consumption and shorten the operating life of the unit itself.

Types of compressors in modern refrigerators, their main properties

Inverter

This is not how an inverter compressor works. It has a power change system. Immediately after switching on, until the temperature rises, it operates at maximum speed. As the temperature approaches the set point, its power gradually decreases. Then it operates at low speeds - only to maintain the set mode. During operation, the power increases only after the refrigerator is opened/closed and a new portion of food is added, causing the temperature to rise. But at maximum they no longer work - there is no need.

So, in refrigerators with inverter compressors, the temperature is maintained stably, with minimal deviations. Inrush currents occur very rarely - after turning off the power and defrosting. The compressor operates constantly, but in a gentle mode, which extends its service life and reduces energy consumption. Most models with high energy efficiency have an inverter compressor.

Compressor type affects energy consumption and noise levels

There is another type of inverter compressor - linear and inverter. In addition to all the advantages described above, there is a very low noise level and a low degree of wear. If you want to choose the quietest refrigerator, look for ones with linear inverter compressors. For example, LG GA M589ZMQZ with a linear inverter cooler at its highest power produces a noise of 40 dB. This is what a person whispers like. Although, this is far from the only refrigerator with such a noise level: LIEBHERR CTP 2521, Bomann KG 211, NORD DRF 200, GORENJE RKI4182E1, BEKO RCSK339M20 W, Indesit TIA 140 and many more models. There are even quieter ones - producing from 23 to 37 dB, but their prices are very high - about $3000.

The disadvantage of refrigerators with an inverter compressor (any) is their price. They are twice as expensive as models with similar parameters, but with a conventional cooler. Another disadvantage is that they are demanding on the quality of power supply. Therefore, when buying a refrigerator with an inverter compressor, take care of a voltage stabilizer. Despite all the minutes, if possible, it is better to take inverter models.

Now you know how to choose a refrigerator based on the main technical parameters. This was the hardest part. It remains to deal with simple things.

Types of defrosting systems

There are many types of refrigeration equipment on the modern market:

• Full Frost;
• Low Frost;
• Total Frost;
• Free Frost;
• Frost Plus;
• Super Frost;
• Less Frost;
• Smart Frost.

All these systems usually refer to No Frost technology refrigerators, which have their own individual features or advantages. There are two main types of No Frost defrosting: complete (when the device does not require defrosting at all) and partial (when it does not require defrosting any of the compartments) .

Free frost system

Free Frost technology refers to a partial defrosting type of two-chamber refrigerators . Cooling fans are located only in the “freezer”, and defrosting of the refrigeration compartment occurs by drip type. The freezer compartment on the back of the appliance does not have an evaporator. Cooling of the refrigerator compartment occurs with the help of defrosting drops and cold air flow. The freshness of products is maintained at +5 ° C and humidity 70–80%.

Frost free system combines drip defrosting and No frost

Full no frost system

Devices operating according to the Full Frost system are distinguished by the location of fans in two compartments simultaneously. This type has a built-in evaporator on the rear panel, which ensures cooling of both chambers at once. The refrigerator maintains a low temperature, so frost freezing occurs exclusively on the evaporator, and its defrosting is carried out using a built-in heater . Cooled air enters the refrigeration compartment through special air ducts, which are periodically closed with dampers.

In Full no frost system refrigerators, fans are located in two chambers simultaneously

Consumers often confuse the “Full” and “Total” systems. However, the latter type means more advanced wind defrosting.

As for the other types (Low, Plus, Super, Less), their names mean more advanced models of refrigerators.

Low Frost technology

Now let's look at another defrosting system in the refrigerator - “Low frost” and find out what it is. Let’s say right away that it differs from “know frost”. This technology appeared relatively recently, it is less than 15 years old. It was developed by the German company Bosch, which successfully uses it in its modern refrigerators.

Over time, “low frost” appeared in models from other manufacturers (AEG, Siemens, Gorenje).

The essence of Low Frost:

• the evaporator circuit is located along the entire outer perimeter of the chamber;
• this results in more uniform cooling and temperature distribution;
• minimal ice formation (from practice, in the form of a very thin ice coating on the walls and shelves);
• very fast defrosting and easy defrosting;
• Applies only to freezer compartments.

As you can see, a Low Frost refrigerator with freezer also needs to be defrosted, but quite rarely. For example, Bosch recommends defrosting once a year.

That is, as in the case of No frost, in fact, defrosting such a chamber is necessary primarily for sanitary reasons. If you handle your freezer very carefully (or don’t use it at all), then you can defrost it once every 5 years.

Why is it difficult to say which system is better?

Experts recommend that when choosing a refrigerator, you take into account certain criteria, including those related to the type of defrosting:

• noise performance;
• dimensions of the device;
• energy consumption class.

However, the set of characteristics of the devices differs regardless of the type of defrosting. For example, if you analyze the positive and negative aspects of the systems, you can note identical reviews about the noise of refrigerators of each type. However, many people prefer a drip device due to its low noise. And yet it is worth noting that noise is a purely individual factor for each model; one cannot confidently say that any “drip” refrigerator will be quiet.

Once I had to face an unpleasant situation with a drip-type device. In the third year of use, the drain hole, which drains liquid into a certain block, became clogged, as a result of which water flowed inside the refrigerator, just under the vegetable drawers. Of course, with regular thawing this could not happen. However, I prefer the No Frost type.

It is difficult to say which refrigerator will be the best for the buyer, because each consumer has individual preferences. However, it is worth remembering the recommendations of experts when choosing a refrigerator:

1. The refrigerator, regardless of the defrosting system, must be washed at least once a year.
2. When buying a No Frost refrigerator, it is worth purchasing containers for food to protect it from drying out.

Dimensions, number and location of cameras

Probably everyone knows how to choose a refrigerator based on its external parameters. If there are restrictions, you have to look for a model that fits into the available space. If there are no size restrictions, everything is simpler - you can choose whatever you like.

Before choosing a refrigerator, familiarize yourself with the most common sizes - you will know which group of manufacturers to look for

There are no strict standards regarding the size of refrigerators, but there are the most common ones:

• depth - 60 cm;
• width - 50-60 cm;
• height from 120 cm to 190 cm.

In general, they are available in different categories - from mini with parameters of 50*50*50 cm, which can be built into living room furniture, to double ones - Side by Side 210*100*80 cm. The table shows the most common sizes of refrigerators of different groups and manufacturers .

Number of cameras and their purpose

In addition to the external dimensions, it is necessary to select the location and volume of the chambers. The number of cameras is from one to six, but the most popular option is two-chamber. They consist of a freezer compartment and a medium temperature compartment.

The number of chambers in the refrigerator is from 1 to 6

Multi-chamber options (from three and above) are also equipped with a compartment with zero temperature and high humidity. This is where food bought “for tomorrow” is stored. It is dangerous to leave them in a regular compartment - they can spoil, there is no point in freezing them - after a few hours you will have to defrost them.

There are also models with several freezers. They maintain different temperatures. The guaranteed shelf life of products depends on the depth of the minus. Another type of chamber is a wine bin. It maintains a certain temperature and humidity. There are dual-mode wine compartments - they maintain different atmospheres for storing white and red wine.

So before choosing a refrigerator, think about which chambers and in what quantity you need, and which you can easily do without.

Freezer compartment parameters

When choosing a refrigerator, pay attention to what temperature the freezer maintains. The duration of storage of products in it depends on this:

• -6°C (indicated by one snowflake *) – storage up to one week;
• -12°C (**) – guaranteed storage up to 14 days;
• -18°C (***) – will last up to 1 month;
• below -18°C (****) – up to 6 months.

  Freezer temperature - pay attention to the parameters. The shelf life of products depends on them

You also need to decide where the freezer should be located. In principle, since this compartment is not used so often, it is more rational for it to be at the bottom. In this case, the refrigerator compartment, which is used much more often, is located somewhere at hip level and above, so there is no need to squat or bend over.

Review of the best models

With a wide range of refrigeration equipment available in the household market, buyers give preference to certain models. Here is a brief overview of the most popular products for home use of each defrosting system.

Refrigerators with drip system

Sharp SJ-B132ZRWH

A special feature of the model is the complete shutdown of the refrigerator when the door is open for a long time. Buyers note this feature as a disadvantage. In addition, the instructions do not contain information about this possibility.

A thin layer of frost freezes on the back wall; the more the refrigerator is loaded, the larger the layer becomes. As for noise, users note increased noise at the time of initial startup, however, after a certain time, the noise subsides and the compressor continues to operate almost inaudibly.

Unlike its counterparts, the refrigerator is equipped with wheels, which makes it much easier to move. In addition, housewives note that the size of the box for eggs is too small - 7 pieces, and those who like to store plastic bottles in doors - the capacity of a two-liter bottle on a shelf in the door. Nevertheless, this model has high customer ratings, characterizing it as an ideal price-quality ratio.

Refrigerator care

In order for the device to serve for a long time and perform its job properly, you need to know the following rules:

1. During transportation, it is important not to tilt the device below 40 degrees. Otherwise, the oil liquid in the refrigerator motor will leak out and fill the refrigerant compartment. As a result, the capillary will become clogged, which may lead to unscheduled repairs. If the device can only be carried horizontally, you must make sure that the compressor tube is directed upward .
2. It is not recommended to install the device in direct sunlight or near a radiator, stove or other heating elements. When heated, the components of the device are destroyed, and the enamel of the case may also deteriorate. The distance to heating devices must be at least 50 cm. When installing the “Warm Floor” system for the refrigerator, it is necessary to provide a place that will not heat up.
3. When placing the refrigerator, it is advisable to leave an additional distance - 5 cm on each edge . It is not advisable to press the appliance against walls and cabinets, since the larger the space, the easier the compressor operates, which lightens the overall load on the operation of the refrigerator.
4. It is necessary to maintain cleanliness in the cells - remove dirt and disinfect. You need to wash the device 2-3 times a year using a special composition and a soft sponge. The back wall also needs to be cleaned. It is important to remove accumulated dust, which shortens the life of the refrigerator and increases energy consumption.

Do not wash the back wall of the drip refrigerator while connected to the network. Before wet cleaning, be sure to make sure that the device is de-energized.

Before carrying out wet cleaning, the refrigerator must be de-energized.

Caring for your drip refrigerator

A drip-type refrigerator needs to be thawed 2 times a month. Do not chip off frozen ice with sharp utensils - this could damage the evaporator.

Experts recommend controlling the humidity inside the chambers, since it negatively affects the coating of the walls and also becomes the key to an unpleasant odor. To avoid moisture, follow these simple guidelines:

• close containers with liquids (soups, drinks), as well as fruits and vegetables;
• Clean the drain channel regularly;
• do not place hot foods in the chambers;
• do not open compartment doors unless necessary;
• The thermostat level is directly set depending on the number of products in the chambers - there is no need to lower the temperature if there are few products in the compartment.

Compliance with these rules will allow you to preserve the operation of an important household appliance for a long time.

It is recommended to store food in the refrigerator in closed containers

Caring for the No Frost refrigerator

Despite the declared independence during defrosting, No Frost appliances also need to be looked after. With this type, defrosting occurs unnoticed by the owner, but it is still necessary to wash off the accumulated condensate from the walls.

Sometimes a thin layer of frost can be seen on the evaporator wall. This is possible if the integrity of the rubber seal is damaged. In this case, air penetrates into the chambers of the device, heats up in the compartment, and liquid is produced, which settles on the surfaces and turns into ice.

Once every six months, it is necessary to unplug the device and defrost it for 12–24 hours, and also wipe all the walls inside and outside the refrigerator. After this, the device should dry for an hour. It is not recommended to immediately after harvesting put food into the chambers and turn on the refrigerator, since the temperature should drop quickly. This puts a serious load on the engine of the device.

Care products

The above remedies are equally useful for all devices, regardless of the defrosting method. The main thing to remember is that when cleaning the surfaces of the refrigerator, you should not use hard brushes or products with abrasive particles, as this can damage the surface of the chamber.

Baking soda has proven itself especially well, since it is ideal for treating the internal surfaces of chambers, since for these purposes it is not recommended to use chemical and soap-based products (soap, dishwashing liquid, etc.). Baking soda is famous for its properties of eliminating unpleasant odors in refrigerator compartments. To prepare the solution you will need to mix 1 tbsp. spoon of soda with 1 liter of warm water.

You can treat the interior surfaces of the refrigerator with baking soda.

In addition, lemon juice is used to remove dirt, and ammonia is used to fight fungus and bacteria. A soap solution is suitable for treating seals and the outer walls of the refrigerator. It must be diluted carefully to avoid the formation of a large amount of foam.

Ammonia destroys fungus and bacteria

After treating the surfaces of the chambers with soap or soda solution, it is necessary to rinse it off with warm water.

The modern market offers many products for the care of refrigeration equipment, which are divided into two groups:

• to eliminate odors;
• for disinfection.

When choosing products from the first group, it is worth remembering that odor absorption is carried out due to activated carbon, which is part of the solution. Some products work on the principle of deodorant - they can only mask the unpleasant odor with aromatic fragrances. The products of the second group are harmless to human health and the camera coating, and do not have aromatic substances.

It is also worth noting that the internal accessories of the cameras also need to be cleaned. Therefore, do not forget to wash the shelves and drawers and then dry them thoroughly.

Advantages and disadvantages

The drip defrosting system is distinguished by its simple design, because its operating principle is based on a common physical phenomenon - condensation. If drip defrosting of the refrigerator compartment stops (the refrigerator is broken), the owners do not need to spend money on expensive parts. Therefore, such models are considered budget. In addition, there is less noise from the refrigerator itself during operation, because there are no additional fans, which are equipped, for example, with the automatic “No Frost” system.

But nothing is perfect in this world. And the drip defrosting system, alas, has its drawbacks.

The biggest disadvantage is that you have to defrost the freezer yourself. Sometimes the drainage hole and the outlet hose become clogged: along with droplets of melt water, crumbs, particles of cling film, food residues, and dust can get there. You can clean the drainage hole and hose yourself using a syringe or soft wire. Better yet, carefully read the relevant instructions and act as it says.
