Drip system for defrosting refrigerating chambers: rid the refrigerator of ice, types of defrosting systems

As the refrigerator works, it creates a by-product - frost, which eventually turns into ice. Previously, the problem was solved by regular defrosting: disconnecting the device from the network and waiting for the ice to melt. This procedure took a long time.

Now there is a drip defrost system, which is based on the principle of evaporation. Ice chunks no longer appear on chamber walls.

How to remove ice from the refrigerator

Nowadays, there are several ways to prevent ice formation. Systems can be:

• manual;
• automatic;
• semi-automatic.

The first option involves human intervention to remove ice and improve performance. unit: the refrigerator is disconnected from the network and wait until the lower tray is filled, in which the melted water. The water is periodically drained until that timeuntil all the ice has cleared from the inner walls. But modern technology is arranged differently, and the process of removing frost has become automated. These are drip defrost systems and the no frost system.

In the first case, when the refrigerator is working, frost accumulates on the back wall, which will slowly melt. The condensate, which is formed in this case, is collected in a special pan and then evaporates. Thus, a cycle is realized within which water turns into ice, then melts, then turns into steam.

The "know frost" principle works differently: during the operation of refrigeration equipment, there is absolutely no frost on the walls.

If we consider semi-automatic devices, it should be noted that human participation is required to start defrosting, then the system will do everything itself. Work resumes automatically after all ice has been removed.

What is drip defrost

The main elements of refrigerators involved in the process:

1. Compressor.
2. Storage tank.
3. Evaporator.

The system got its name because of the principle of operation. The device is being used and a slight layer of frost forms on the rear panel. The refrigerator is running, heat is generated, and the ice is melting. As a result, a small amount of water is collected, it slowly flows into a special hole located at the bottom of the chamber, connected to a reservoir, inside which it evaporates.

In order to keep the unit in full working order for many years, experts recommend carrying out a complete defrosting at least once a year, disconnecting it from the mains. This is the only way to remove impurities and prevent unpleasant odors.

Advantages and disadvantages

If we compare the drip and manual systems, then the first has a number of significant advantages:

• there is no need for regular defrosting;
• saving time, because ice is removed automatically;
• the simple principle of operation minimizes the occurrence of failures during operation;
• favorable microclimate: the air inside is not too humid and not dry;
• a significant range of models;
• middle price category.

There are few disadvantages, but they are still there. So, you will have to turn off the unit 1-2 times a year for complete defrosting, it takes more time than equipment with fully automatic know-frost technology. Another point is that the drip system does not work on the freezer: if too much ice has accumulated in the freezer, you will have to turn off the refrigerator. But you should not refuse to buy because of this: the ice freezes very slowly.

Features of the No frost system

When choosing a system for defrosting a refrigerator, you must also familiarize yourself with the no frost technology, which has a number of advantages:

• the refrigerator and freezer are cooled by the same fans, so there is no need to defrost the freezer separately;
• lack of significant condensation on the back wall;
• minimal care;
• very fast cooling of the inner space.

But there are also some disadvantages of the system, in particular:

• products will have to be packed before storage, as dry air circulates inside;
• it is recommended to turn off the refrigerator at least once a year for cleaning;
• the unit consumes a little more electricity;
• hidden fans can create additional noise during operation.

Comparing the two systems with each other, we can conclude that drip defrosting is the best option. Such refrigerators practically do not make noise, the air inside is not too dry, defrosting occurs automatically. However, this option is not suitable for people planning to actively use the freezer compartment, because it will have to be defrosted separately. In addition, the mid-price category makes such refrigerators popular among users, because "know frost" units are more expensive.
