Modern refrigerators differ from their past counterparts not only in appearance, but also in technical filling. A dry-frozen refrigerator does not need to be defrosted before serving. This result was achieved due to the circulation of the air flow, which differs from the drip method that was used before.


Drip cooling is carried out by the formation of condensate on the rear surface of the refrigerator, it freezes, the wall is covered with hoarfrost. After a while, the system automatically turns off, the ice begins to melt, water flows down through special gutters. When you turn on the system, it evaporates and freezes again. Dry frost (No frost) has several advantages, but before familiarizing yourself with them, you need to understand what it is and how the cooling process occurs.

Features and principle of dry freezing

Reducing and maintaining the set temperature with No frost occurs by moving the air masses along the inner plane of the refrigerator. The movement is achieved by the fans. With such freezing, there is no ice on the surfaces, however, condensate still forms and flows into a separate container, which is interconnected with compressor. The unit is constantly working, so its body is very hot, due to this, the liquid evaporates and again becomes a participant in the cooling.

Refrigerators equipped with this system show excellent results in reliability and durability. Users note high freezing efficiency and ease of maintenance. After 3-4 hours after turning off, you can start cleaning the surfaces. Manufacturers It is recommended to defrost such a refrigerator several times a year.

What are the benefits of No Frost?

This cooling method has characteristic advantages:

  1. The main advantage of cooling with dry air is the absence of ice on the surfaces, so there is no need for systematic defrosting.
  2. This freezing method contributes to an even distribution of temperature, so the indicator on different shelves is almost identical.
  3. If the door has been open for a long time, the temperature in the chamber rises, but when closed, the system will quickly bring the value to the required value.
  4. A refrigerator happens with dry freezing in the freezer section and with drip-type cooling in the refrigerator. This allows you to use an alternative option, because No Frost has negative aspects.

The main disadvantages of refrigerators with dry freezing

Despite the significant advantages, the system has a solid list of disadvantages, because of which many refuse to buy a refrigerator with dry freeze:

  1. Active movement of dry air reduces humidity, which provokes the rapid drying of products. Although the problem can be solved by storing open products in plastic bags, films or sealed containers.
  2. Refrigeration unit requires more Energy consumptionthan for similar devices with a different type of freezing.
  3. Users note increased noise during the operation of the device, although modern refrigerators managed to cope with this problem.
  4. It is believed that in the process of freezing, magnetic waves are emitted that are harmful to health. This assumption did not find a scientific justification, so now we can safely say that the damage from No Frost is as much as from a cooker hood or stove.

After a detailed analysis of the advantages and features of dry freezing, you can make a choice about the advisability of buying a No Frost refrigerator, or choose another type of defrost. The device guarantees not only high freezing efficiency, but also safety and ease of operation.
