How to choose the right refrigerator

Refrigerators, want every month  manual defrost and wash, are gone. Modern models refrigerators have an automatic defrost system performs its functions unbeknownst to them  owners. However, manufacturers recommend still order prevention thawed refrigerator 1—2 times per year manually. And yet with the technology, automatic defrost it will not remind struggle with icy rocks — details of the fridge covered only a small touch of frost.

the Most common technologies automatic defrosting are drip (crying) and windy, which is No Frost. Most often in modernrefrigerators meets drip defrost system. It is that  on the back wall of the refrigerating chamber (for freezers drip technology is not used) is the evaporator. Usually it is located inside the wall due to the fact that the products must not come into contact with the evaporator — it affects his work. In this case, the water may not drain in a special container and on the bottom of the camera. In addition, “open” the evaporator can accidentally damage. The evaporator maintains a low temperature of the back wall, making it condense water vapor and formed icicles. Other walls this is not the case. At the end of the cooling cycle when the compressor stops, the evaporator is heated. Accumulated on it the ice thawed and the water flows into a special container by grooves. When the compressor starts working, the water in the tank heats up and evaporates. The process begins again with a new cooling cycle.

In refrigerators with system No Frost evaporator is set behind the rear wall of the refrigerating chamber or above the freezer. He have fans that circulate the air inside the refrigerator. The evaporator, as in the refrigerator with a drip system, provides low temperature back wall. When the compressor stops, the frost melts and evaporates.

So, what are the advantages and disadvantages of No Frost? because of the ventilation system in refrigerators system No Frost products dry up faster. Therefore, they are preferably stored in packages. 

There is a belief that refrigerators with automatic defrost No Frost no need to defrost manually. But this, again, wrong. Refrigerators and drip, and windy systems should be thawed only once or twice a year, as any refrigerator accrue smells and wiped it does not hurt.

the Main advantage of refrigerators with the system No Frost is the uniform temperature of the air inside the refrigerator. The temperature difference on the upper and lower shelves of the refrigerator compartment does not exceed two degrees Celsius. For comparison: in refrigerators with a drip system, the difference may reach five or six degrees. And in the freezer without No Frost — up to nine degrees. Temperature uniformity better security products.

Another important advantage of a No Frost is that the system works as in the refrigerating and freezing chambers, while drip can only work in refrigeration. 

the ventilation System allows the refrigerator to quickly regain the temperature after the door is opened. However, it is not too much — much greater role here is played by the power of the refrigerator.

Among the disadvantages No Frost called relatively high level of noise during operation. Additional noise provide fans. However, some models of refrigerators with the system No Frost equipped with a very quiet fan, thus run much quieter some drip.

a Pretty significant disadvantage No Frost is that cumbersome mechanism of the evaporator is additional the volume of the refrigerating chamber. As a result, the same size refrigerators with drip defrost noticeably bigger.

Refrigerator system No Frost ceteris paribus consumes more electricity than a refrigerator with weeping defrost. The difference in the power bill will be small, but for those who like to save money wherever you can, it's still a disadvantage.

Refrigerators with a drip system and No Frost differ in price. Refrigerator with windy technology thawing will cost more expensive than similar models with "crying" technology. However, this difference is not too much.

In General, the advantages and disadvantages of the system No Frost (compared to a common drip system) almost cancel each other out. Therefore, the system automatic defrosting usually not a decisive criterion when choosing a refrigerator. But the advantages and disadvantages of the different systems should be taken into account.
