What is a refrigerator drier defrost system

Modern household models of refrigeration units are significantly different from those that frosted a lot of ice and required frequent defrosting. Their differences in some parameters are substantial enough. Let's figure out what is best to choose - a refrigerator with drip defrosting system or with no frost system.

Main characteristics

Refrigerators with both defrosting systems are popular - know frost and drip. To make a choice, you should know the features, as well as the pros and cons of these models.

No frost

The advanced no frost technology has made it possible to produce refrigerators that do not require defrosting at all. Such refrigerators have a freezer and a refrigerator, as well as an evaporator and compressor. Cold air is constantly circulating thanks to the fans.

Uniform product cooling

The even distribution of cold air leads to the fact that ice practically does not form, allowing the maximum use of the useful volume of the device. In this case, the products receive uniform and rapid cooling.

Note! To maintain maximum nutrients, almost all models are equipped with a special compartment with a constant temperature of 0 degrees.

There is no frost and freezing of ice in the chamber. Periodically, the fan stops working, at this time the heater starts, which defrosts the frost from the evaporator. The resulting water flows through special inclined systems into a container located behind the unit. There, the liquid simply evaporates, you do not need to remove it.

The principle of the drip system

Devices with such a system of work are very popular. The evaporator located on the rear wall cools the internal chambers. During its operation, moisture accumulates, which flows through a hole at the bottom of the refrigerator into a special container.

If the compressor is functioning actively, moisture can freeze, forming ice.

Harm of the know frost system: myths and reality

There are many myths and speculations about the no frost system.

Myth # 1: Health Hazards

The most common is the health hazard of such a system. This statement has no foundation. Equipment (compressors, etc.) in refrigerators with no frost uses the same as in devices with a drip system. The refrigerants in them are also the same.

Myth # 2: Overdrying Foods

It is widely believed that the know-frost system overdries products. There is some truth in this statement. Continuous fan operation, which provide air movement through the chamber, accelerates the drying and oxidation of already chopped and cooked food. To preserve the products, it is necessary to cover them with cling film or store them in closed containers.

Myth number 3: defrosting is not needed

The instructions for the refrigerator of the no frost system indicate that the device works efficiently and without defrosting. In this case, it is advisable to turn off the refrigerator once a year in order to carry out a general cleaning in it.

Myth No. 4: there is less space inside the no frost refrigerator than in a drip of the same size

This statement is true. Due to the nature of the device, the internal volume of the no frost refrigerator is slightly smaller.In order not to make a mistake with the choice, the dimensions of the cameras should be examined before purchase.

Comparison of two systems

To determine which refrigerator is better - with a frost or drip know system, it is recommended to analyze the table below.

Selection recommendations

1. It is necessary to foresee a set of containers for storing products. Especially advice is relevant for refrigerators with the no frost system.
2. At least once a year, thorough cleaning in the refrigerator should be carried out, regardless of its operating system.
3. The noise level, energy saving class and capacity of the device must be taken into account.
4. Additionally, you can study the rating of the best models in the desired price category.

Wet cleaning must be carried out.

On which model to choose, each determines based on personal preferences. No frost will cost more, but will create additional convenience. In addition to the price, other parameters should be considered. Each model has its pros and cons, so it is important to study all the important characteristics beforehand.
