Know Frost or a drop cooler - which is better?

In the world of modern household appliances, refrigerators with dry freeze are quite popular. But we need to figure out whether such an aggregate will always work properly, as the manufacturers assure it. The air in such models is operated by fans hidden in the body. Actually, they prevent the formation of condensate on the walls, and therefore do not become "snow coat".First, the Noau Frost system was developed specifically for regions with a very humid climate, because the usual technique there had to be very often thawed. In conditions of our climate, this system can not be called ideal, because its use leads to the fact that some products dry up quickly( due to the rapid loss of moisture).And yet, Nou Frost or a drop cooler - which is better? We will deal with this in this article.

Features of drip coolers and No Frost

In fact, they work in the same way:

• Inside of them, a refrigerant circulates through special pipes, which, when pressure changes, changes from a liquid state to a gas.
• In the process of processing this substance, heat is collected in the cold rooms from the atmosphere, due to which the low temperature is maintained.

Important!"Crying" refrigerators in terms of use, of course, are not so convenient - they constantly form ice, and they must be cleaned with hoarfrost. But they are much cheaper, they can easily be repaired.

The most important difference between them is the way the liquid is withdrawn. Namely:

• In ordinary units, droplets are collected directly in the refrigerating chamber on its rear wall, and then drain into a special container.
• In models with dry freezing, condensation of moisture is carried out directly on the evaporator, which is outside the chamber.

Basic misconceptions about refrigerators No Frost

Before deciding which refrigerator is best - drip or Know Frost, first read some myths that have developed around the latter:

1. The products literally dry out before our eyes. An assertion of this kind is controversial. If you store the food correctly, cover with food wrap or put in containers - they will not dry out. In addition, tomatoes and apples, berries and some fruits are stored much longer in a dry environment. In addition, storing products in an open form is illogical, because because of this there is an unpleasant smell.
2. Models with a dry freeze function do not need to be defrosted. Yes it is really so, but nobody cleaned and cleaned all household appliances in the house. If you do not wash your refrigerator, it will just boil bacteria.
3. There is not much room inside the refrigerator. Naturally, the fans take up a lot of space in the chambers, but still a useful amount is kept enough.

Unequivocally answer the above question, Know Frost or a drop cooler - which is better, it is difficult, because many manufacturers simply combine both successfully used systems in one model. That is, the freezer comes with the No Frost system, and the refrigerator compartment itself remains drip. In any case, you need to rely on your needs.

The main pros and cons of these two

systems As we have already found out, these systems are the most popular today, but to understand, No Frost or a drop system - what is better, you need to compare their advantages and disadvantages.

How does the droplet system work and its features?

Many inexpensive refrigerators have just such a defrost system. That is, the cooling element is attached to the rear wall of the chamber, and it cools it. As soon as the compressor starts working, the temperature of the back wall becomes negative, the water starts to condense and turn into ice. As soon as it turns off - ice starts to melt, water drains into the right capacity and evaporates due to high temperature. Advantages of the "crying" system:

• Low cost;
• Simple design, allowing you to place the maximum number of products;
• Low power consumption;
• Simplicity and ease of repair;
• Low noise level.

Disadvantages of drip coolers:

• Too humid cameras inside;
• Need for regular defrosting;
• Too long cooling from the first start;
• Non-uniform cooling of the upper and lower shelves.

How does the forced circulation system work?

In models No Frost the evaporator is located outside the refrigerating chamber, namely in the case itself. The circulation of air is due to the operation of one or more fans. The air that is blown out of the chambers immediately cools and comes back through special holes. Condensation settles directly on the walls of the cooler. As soon as the compressor stops working, it immediately turns on the heat, which helps to defrost frost and excess moisture to drain into a special tray. Which refrigerator is better - drip or Know Frost, it's up to you, but it is necessary to get acquainted with the information below.

Positive aspects of the system No Frost:

• No condensation;
• Products are stored longer due to low humidity in the chambers;
• The temperature is uniformly maintained over all chambers;
• From scratch, the system cools very quickly.

Cons of these models:

• Products should be stored only packaged, as they can dry out due to a too dry atmosphere;
• High level of electricity consumption;
• Additional fans create a high level of noise;
• High cost.

Drawing conclusions

Know Frost or a drop cooler - which is better? The cost of the refrigerator directly depends on the efficiency and simplicity of the defrosting system. Do not forget to take into account when buying the noise level, the amount of energy consumed and other nuances that affect the price and quality of the unit. Whatever refrigerator you choose, you will need to wash it at least once a year. And do not forget to buy special food containers for proper storage of food.
