WHAT IS KNOW FROST in a refrigerator - the principle of operation of No Frost and a drip system, which is better and their differences

No Frost is a modern refrigeration technology for the refrigerator and freezer that has replaced the classic drip method.

"Know Frost" is a cooling system for freezing and refrigerating chambers, which provides forced circulation of cold air and prevents the formation of ice on the walls of the refrigerator.

How does No Frost work in the refrigerator?

Literally the term "No Frost" is translated from English as "no frost". Indeed, in refrigerators with the No Frost system, ice does not form on the walls of the chambers. What is the difference between this system and a drip system, read below.

No Frost ensures an even distribution of air throughout the refrigerator compartment. Due to this, there are no zones with sharp temperature drops, due to which moisture condenses and freezes. This is not to say that ice does not form at all: it appears ... outside the chambers and is periodically removed. Thus, No Frost protects food from freezing and does not burden the owner with additional worries.

The principle of operation of the refrigerator No Frost

  • The evaporator is located behind the back wall inside the refrigerator body or above the freezer compartment.
  • Fans are located behind it, which blow through the evaporator and pump air into the chambers through special channels. This ensures a constant circulation of cold air.
  • Moisture in the refrigerator does not freeze on the walls, as in the drip system, but "settles" in the coldest area - the evaporator.
  • Periodically, the compressor is turned off and the heater is started, which removes the frost layer on the compressor.
  • The resulting moisture is discharged through the grooves into the tank and evaporates quickly.
Thanks to these features, the refrigerator is unpretentious in maintenance.

Benefits of No Frost

  • Thanks to air circulation, after closing the refrigerator door, the set temperature in the chamber is restored faster than in conventional units.
  • The Instant Freeze function allows you to chill or freeze large quantities of food in a matter of minutes.
  • The humidity level in the chamber is 2 times less than that of refrigerators with weeping walls. Therefore, bacteria multiply more slowly.

Disadvantages of the No Frost system

There are preconceptions that refrigerators with No Frost make a lot of noise, consume a lot of electricity and dry food. In fact, everything is relative.

  • Evaluate the level of noise and energy consumption not by the presence of the No Frost system, but by the technical indicators of the refrigerator.
  • The products also dry in drip refrigerators. In models with No Frost, this happens a little faster, but with any system, food should be stored in airtight containers or in sealed containers.

Thus, the disadvantages of refrigerators with No Frost are controversial and are more than offset by the advantages.

These units, of course, have a higher price, but the opportunity to free yourself from the ancient tradition of defrosting refrigerators is worth it. We think the question is: "Know frost or drip system?" resolved by itself.

Now you thoroughly know what No Frost is in the refrigerator. If you have already used devices with this system, we will be glad to your opinion in the comments.
