Refrigerator manufacturers are struggling to beat the competition. What tricks they resort to: they create models with an incredible design, come up with new functions. All this with one goal - to attract buyers. A huge selection of different models puts shopping center visitors into a stupor, it is difficult to single out one model from such an abundance. This article will discuss refrigerator defrosting systems, after reading the material, readers will be able to understand which device for storing food is more suitable for them.
When buying a refrigerator, one of the most important criteria is the method of defrosting the device. There are three main technologies for this process:
1. drip;
2. combined;
3. air, better known as "No Frost".
The main purpose of these systems is to prevent the formation of a snow crust on the surfaces of the freezer and refrigerator. Although it cannot affect the operation of the engine or other elements of the device, but its presence impairs the heat exchange between the stored products and the evaporating device. Because of this, the freezing mode is significantly worsened, an increased load is placed on the engine.
drip system
This defrosting method consists in the fact that condensate collects on the back wall, this happens due to the temperature difference in the room and the refrigerator when it is opened. Each time at this moment, warm air enters the device, which contributes to the formation of moisture. Periodically, when there is a pause in the operation of the compressor, the liquid flows into a special container, after which it evaporates. At the same time, frost does not form in the refrigerator compartment, but it is present in the freezer. Therefore, periodically the refrigerator will have to be defrosted.
Frost Free
In refrigeration equipment with such a defrosting system, forced air circulation is used, while moisture particles are removed from the refrigerator compartment. The technology is good because ice build-up on its walls will not form in the freezer compartment either. This is her huge plus. Since the air is constantly moving inside the appliance, the food is cooled evenly and therefore has a longer shelf life. There is also a minus: the products, being constantly in the "draft", are dried. Keep them in sealed packaging.
The methods described above for defrosting household appliances are not ideal, each of them has drawbacks, so manufacturers are constantly looking for a way out, trying to find the best way. As a result, it was decided to create models that combine both options. This will be discussed below.
Combined system
This technology is used only in expensive models. The main point is as follows: the refrigeration compartment is defrosted by a drip system, and the freezer compartment is defrosted by forced ventilation. Such an implementation from the point of view of the consumer does not have disadvantages. There are technical disadvantages: the refrigerator has more blocks, as a result of which its cost increases.
Knowing these features, it will be easier for you to decide on the choice of a refrigerator. When giving preference to a particular model, be sure to ask about its energy saving class and capacity - these parameters are also important.
