drip systemToday, it is quite "smart" units that do not require human intervention in the process of operation. But is this how it is in your kitchen? Is a dropping system of a defrosting of a refrigerator a relief for a housewife or, on the contrary, additional efforts? Let's figure it out together!

The principle of operation of the drip defrosting system

Refrigerators with a drip defrosting system today are the most popular among buyers. They are affordable and quite comfortable to use. Note that it does not need to be thawed manually, as outdated Soviet models. And now you will not see the huge snow "coat" on the freezer or the back wall of the refrigerator compartment - thanks to the drip defrosting system and electronic sensors inside the device.

The principle of operation of such a refrigerator is based on the phenomenon of condensation. An evaporator is located on the rear wall of the instrument, in which the coolant is injected into the tubes. Thus, the inner chamber is cooled and the required temperature for storing food is reached. At the same time, all the moisture inside the refrigerator compartment turns into ice crystals, which are deposited on the inner wall of the device. As soon as the maximum thickness of the ice layer is reached, the compressor automatically shuts off, the back wall of the chamber heats up, the ice melts, and the liquid flows into a special container and evaporates.

In some models, an alarm is triggered when too much ice is frozen, it’s time to disconnect the device from the mains and allow it to thaw. Of course, automatic technologies are more convenient, but simple, manual control is more reliable.

Sometimes, the cumulative capacity needs to be emptied on its own. And manufacturers recommend from time to time to clean the discharge hoses and openings - to avoid flooding during defrosting. Before such a procedure, do not be lazy to read the recommendations carefully - how and with what you can clean the drainage in order not to damage the refrigerator.

The peculiarity of such a system is the characteristic sound of a dripping or flowing liquid. Do not worry, because this is a sign of proper operation of the device, and not vice versa. In common people they are often called "crying" - now you understand why.

Comparison of the drip and Nou Frost systems of the

Household appliance manufacturers are not satisfied with what has already been achieved, and strive to create more convenient and practical appliances for their customers. Another improvement in the refrigerator was the No Frost system, which confidently claims leadership in the domestic refrigeration industry. Let's compare both systems.

The principle of operation of No Frost is similar to the droplet one; cooling inside is achieved by forcing 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, it is necessary to defrost less often. In addition, you will not hear the sound of falling drops, and the drainage system is clogged several times less. However, such a system is technically more complex, so if you find an unscrupulous manufacturer, then get ready for frequent and expensive repairs to your home appliance.

If you compare the two systems of the refrigerator, 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.

Advantages of drip:

  • reliability;
  • noiseless;
  • minimum power consumption.


  • periodic cleaning of the drainage system;
  • manual defrost freezers;
  • temperature difference in the upper and lower parts of the chamber.

No Frost Benefits:

  • minimum maintenance during operation;
  • uniform temperature distribution;
  • no ice layer on the walls of the chamber;
  • rapid recovery of low temperature after thawing.


  • noise during fan operation;
  • large amount of electricity consumed.

Compared with the No Frost models, “crying” refrigerators are more powerful and roomy - you can choose a huge model for a large family and an in-built appliance for your kitchen furniture. Moreover, the products in the units with the drip system are not chapped due to the constant air flow, which is injected by the built-in fans in the No Frost devices. But you can just carefully monitor the safety of the packaging or wrapping food products with plastic wrap - then no weathering will occur.

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, you should read the opinions of experts, pay attention to the 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.

Consumer opinion

The drip defrosting system is successfully used in most modern domestic refrigerators. Such models are in demand among consumers and occupy the top positions in the price-quality ratings. A buyer, who came to the store for an appliance with a drip system, can argue several factors at once:

  • reasonable price;
  • large model diversity;
  • intelligent technical specifications.

Also, it is worth considering the fact that there is practically nothing to break in a refrigerator with a dropping defrost system - the system is very simple and reliable due to the lack of complex electronic components. Repair of such devices is usually the fastest and most inexpensive.

The only caveat, which some customers seem to be a significant drawback of the drip defrosting system, is the high level of humidity inside the refrigerator compartment. Sometimes, the liquid accumulates in the lower compartments of the refrigerator, and this is a serious threat to the products that lie there. Frequently conduct an audit on the shelves of the device and do not forget to monitor the drainage system.

How to defrost a refrigerator with an

drip system No matter how “independent” the refrigerator is in your kitchen - sometimes you have to pay attention to it and turn off the device for defrosting or cleaning. We want to share with you some secrets and nuances that will help ease your efforts and extend the life of your household assistant - the refrigerator.

If there is a single-compressor refrigerator in your kitchen, then during defrosting you will have to take care of all the products, because both cameras will be disabled.

If you are the owner of a two-compressor device, you can defrost only one of the chambers. However, do not forget that from time to time you need to turn off the entire refrigerator and carry out an audit and disinfection on its shelves.

If you have an alert system in your fridge, just respond to the sensor signal and de-energize the device in time. Also, it is worth prudently to lay the floor around the refrigerator with floor cloths and check the tank for melt water - to avoid flooding. Hurry up? Open the door of the refrigerator or freezer - warm air will help the device to quickly thaw. However, in no case should anyone try to break the ice off the walls of the chamber or the evaporator tubes - the device may be damaged. Also, it is necessary to refrain from aggressive detergents and hard metal brushes - to keep the plastic of the device intact and intact.

In more advanced models of refrigerators, an automatic stop of the compressor and gradual defrosting is provided. When the ice layer disappears - the device itself starts the discharge of the refrigerant in order to lower the temperature inside the refrigerator or freezer. Such technology seems to be extremely effective and convenient for some consumers. Do you have free time? It is necessary to turn off the device from time to time independently and check storage tanks and drainage system.

To get rid of the blockage of the drainage system - use a syringe or a flexible long wire.

Before turning on the thawed refrigerator, wipe the walls and shelves of the appliance dry with a soft sponge. There is an opinion that first you need to let the refrigerator "cool down" and reach the desired temperature, and only then you can proceed to the placement of products on the shelves of the chamber. This is a delusion, which can lead to excessive loads and compressor breakdown, therefore, load the refrigerator immediately, and only then turn on the power supply.

We hope that this article fully answered the question: what is the drip defrosting system of a refrigerator? Now you know what its advantages and disadvantages are, and you won’t save it before thawing such a device. How convenient is such a refrigerator - you decide.
