Today infrequently meet refrigerators that need to be once a month or two to defrost. Before the defrost process is accompanied by disconnecting from the power supply, the release of the products, ice thawing, washing and drying. Spending time on the maintenance of advanced models account for very little.
Refrigerator is the purchase of a few years. Therefore, it is necessary to choose consciously. The main parameter to which you should pay attention to - the defrost system. Their is two - No Frost and drip.
Her name is crying because of the sound of dripping water during automatic defrost. Drip thawing works like this:
- The back wall is built evaporator, which cools it. condensate freezes gradually settled here.
- When ice grows certain level inside the compressor is deactivated. The rear wall is heated again.
- Samorazmorozka begins - the ice melts and flows into the sump.
- After defrosting, the compressor is switched on again. Under the influence of heat emanating from it the water evaporates.
At the end of this process, you need to check the capacity for moisture. If it is full, the water should be poured from her own. Exhibited by temperature and quantity of products in the chamber depends on the frequency of switching on and off of the compressor. When the device is working properly defrost drip is almost invisible. It happens all the time, without external involvement of the owner.
How does the No Frost system
No Frost translated to English literally means absence of frost. refrigerators equipped with this technology is relatively recent. Unlike the drip system that is added to the ventilation system. Gradually cooling process is as follows:
- The evaporator as well as in dropping technology off wall.
- Built-in fans cool air inside the inflated. This is formed by condensation that accumulates on the evaporator - so there is a hoarfrost.
- It disappears from the walls by the temporary operation of the heater. The resulting wherein the moisture evaporates due to air circulation.
Despite the fact that the system is fully automatic, at least once every two years, even such appliances should be turned off from the network and completely clean.
The advantages and disadvantages of both systems
To select more suitable for yourself kind of defrosting the refrigerator, you need to take into account their differences.
Pros refrigerators with drip technology:
- lower price devices;
- big choice;
- good capacity;
- efficient power consumption;
- low noise level.
Among the advantages of technology with No Frost system release:
- It does not require frequent maintenance;
- uniform temperature within the entire refrigerating compartment;
- equipped with functions and rapid thawing superzamorozki;
- there are models with version Full No Frost - in which both cameras are equipped with this technology;
- It is formed very little condensation on the back wall.
In addition to the advantages of both systems, we should not forget about their disadvantages.
The disadvantages are crying defrost:
- It does not work inside a freezer;
- Condensation often no time to completely drain the wall and the refrigerator is in the same place;
- uneven temperature conditions inside;
- After defrosting the appliance slowly gaining the desired temperature.
Refrigerators with No Frost have these disadvantages:
- high price;
- smaller usable volume;
- noisier work;
- not sufficiently economical.
How to choose
Knowing the difference between the two defrost systems, it is easier to make a choice and see which one is better.
For budget conscious buyers definitely better suited drip. If more frequent care unit is a problem, then stop for a system without frost. But in case of damage repair of such equipment more will come.
