What is No Frost (Frost Free)? Which refrigerator is better: with a No Frost system or a drip?

Models of well-known firms do not presuppose manualdefrosting. They built a special automated system, which independently removes a thin film of frost. Now there is no need to allocate a whole day to fix the refrigerator and get rid of large pieces of ice.

Types of automatic defrosting technologies

There are many automatic defrosting systems, but

the most famous of them are:

• 
  drip;


• 
  windy (NoFrost).

Drip technology works this way. On the back surface of the device is attached a special evaporator, built into the wall. It should not come into contact with food and, therefore, it is reliably hidden. However, there are models in which it is located on the surface. This adds some inconvenience: the water flows directly into the chamber, and the device itself can be inadvertently damaged or stained.

The evaporator is necessary to keep the temperaturethe back of the refrigerator at low elevations. There is a freezing of water and ice is formed. At the end of the cooling mode, the evaporator is heated, and the thawed ice flows down the gutters into a special container. Further, the collected liquid gradually evaporates, and the system starts to work in a similar mode. With the dropping technology figured out, but what is its difference from No Frost? What is it?

No Frost technology works like this: The evaporator is introduced into the rear wall of the freezer or above it. The device works with the help of fans, which help the air circulate inside the refrigerator itself. The evaporator of this system is also equipped with dropping technology. There is a decrease in degrees on the back surface, the process of thawing, and then evaporation.

There is an opinion that the No Frost system contributesweathering of products, because of what they quickly dry up. In fact, this is not so. A lot of experiments have been done, proving that the technology does not conduce to drying, although theoretically it is possible.

The main advantages of the No Frost system

• 
  temperature distribution inside the refrigeratoroccurs evenly. The difference between the upper and lower divisions is only a couple of degrees. This feature helps keep food fresh as long as possible;


• 
  The ventilation process promotes a rapid temperature recovery after the closure of the refrigerator;


• 
  The No Frost system functions in the refrigerator and inside the freezer at the same time.

Disadvantages of No Frost

• 
  refrigerators with this system work quite noisily due to built-in fans;


• 
  The evaporator is quite large and clutters a part of the freezer space;


• 
  refrigerators with No Frost consume a little more electricity than with other systems;


• 
  comparatively high cost.

Now you can compare the pros and cons of different systems and choose the most suitable model for yourself.
