For some residents, choosing a new refrigerator can be a whole problem. In running around shopping centers and megamarkets, you will understand that you need to take into account many nuances: dimensions, color, volume of the refrigerator and freezer, the number of compressors. And then your kitchen will have a device that best meets your desire. However, along with the above characteristics, pay attention to the defrost system of the refrigerator . In modern units set two types - the now fashionable No Frost and drip system. The latter is the most popular defrosting system to date. About it and talk.
What is a drip defrost system?
Surely, many of us still remember the Soviet refrigerators, which had to be thawed every 1-2 months, since a large layer of frost was set on the walls of the refrigerator and freezer. Now an automatic defrosting system has been introduced, according to which the device itself controls this process. By the way, most of the refrigerators produced are operated by a drop defrost system. Its essence consists in equipping the rear wall of the refrigerating chamber of a special panel - the evaporator, that is, the cooling element. Due to this, the temperature of the back wall is somewhat lower than the rest of the chamber walls. Therefore, the condensate settles in the form of a small layer of ice. Then later, according to a special operating cycle, the compressor stops and the rear wall heats up. The ice on it turns into water and flows down the wall into the drain tank through the holes. In this tank (most often a tray or tray) moisture evaporates.
By the way, drip defrosting is often called "crying". Many owners of devices with this type of defrosting notice the sound of falling drops or dripping fluid inside the unit. This condensate is quite normal and indicates the correct operation of the refrigerator.
Advantages and disadvantages of drip defrost of the refrigerator
So, we pointed out above that a drip defrost system is used today in most refrigerators. This is primarily due to the simplicity and efficiency of the system. After all, it is based on a phenomenon familiar to us from the course of physics, like condensation.
The advantages of the drop system of the refrigerator can be attributed to the low cost in comparison with the devices where the No Frost system was installed. This is due to the simplicity of the design. From here follows the next plus of drip defrosting: when a refrigeration unit breaks down, repairs are cheaper and faster than the No Frost system. By the way, many damages at refrigerators No Frost to repair are unsuitable, and therefore such necessary in each house of the device should be changed.
The next advantage of droplet defrosting can also be estimated in comparison with the so-called "no frost" system. The latter, as noted by many consumers of No Frost refrigerators, makes the instruments quite loud and noisy due to the cyclical operation of the fan. When, like ordinary refrigerators, they work relatively quietly and do not distract from everyday affairs in the kitchen. In addition, because there is no fan in the devices with drip defrosting does not occur
If we talk about the drawbacks of droplet thawing, we should say that there are not so many of them. The main thing is that there is a drip defrost of the refrigerating chamber and only. That is, in the "freezer" over time will appear a layer of ice, and therefore produce defrosting will need to be every six months. This is not a problem if your device is two-compressor. And if he only has one compressor, then disconnect the power from the whole refrigerator. In addition, droplets dripping on the back wall of the chamber create high humidity, which is not so good for storing food.
