Drip defrosting system: if your refrigerator "cries" is good

The work of any household device has its ownthe reverse side of the sparkling medal, and not just the convenience provided to man. The existing defrosting systems of refrigerators clearly confirm this. In fact, any equipment for the production of cold "produces" also frost and ice in the form of intentions, periodically formed in the refrigerator and freezers. Because of this, the efficiency of the refrigerator decreases, the compressor operates in an overloaded mode, which significantly "eats" its resource and is fraught with premature failure. To prevent this, the designers have developed defrosting systems.

The most popular is the drip systemdefrosting the refrigerator (also called "crying") - because of the simplicity and the corresponding cheapness. It is equipped with household refrigeration units of low and medium price segments. Nevertheless, it relieves housewives from the defrosting of the refrigerator by hand, which has previously been spent a lot of time and effort. Now such an "operation" is the destiny of old single-chamber or very cheap units.

Drip chamber defrosting systemis implemented by a cyclic "freeze / thaw" scheme. Structurally, it is provided by the location of the evaporator (cooling element) on the rear wall of the refrigerating chamber. During operation, the compressor pumps the refrigerant and the wall cools down. Simultaneously, ice forms on the evaporator. At regular intervals, the compressor turns off the compressor on the command of the device. Since the air temperature surrounding the cooling unit, plus, ice on the evaporator melts. The resulting moisture droplets flow down the wall and through the drain opening accumulate in a special container located above the compressor. During operation, it is heated quite strongly, this heat is transferred to the water in the container, and it evaporates.

In principle, the drip defrost systemimitates the process of the circulation of water in nature, based on all the physical laws known from the school desk. Hence the combination of simplicity and efficiency. "Reasonableness" to the system adds control of the frequency and duration of the defrost cycles by means of a manual temperature regulator.

In most models of refrigerators, a dropDefrosting is absolutely noiseless. In some there is a crackling of melting ice and dripping of water flowing into the container. These sounds, like the droplets of moisture on the back of the refrigerator, are an indication that all of its systems work correctly. More noise is simply nothing - a fan, as in the device No Frost, is not needed. From the latter, the drip defrosting system is advantageously distinguished also by higher humidity in the refrigerating chamber, which prevents rapid dehydration of the stored products.

The "freeze / thaw" cycle occurscontinuously in automatic mode, which does not require any special operations from the user, except hygienic care of the refrigerator. Regularly check the opening of the tank, where melt water flows, for a blockage.

As for the freezer, the droppingThe defrost system is not designed for it, and this is its only serious drawback. But however, if the refrigerator is maintained in good condition, it physically can not build a "coat" in the freezer in a short time. For defrosting it is enough to disconnect the appliance from the mains and wait until the ice in the chamber melts. And it will not be necessary more than once in a half-year.
