What is the principle of the frost free refrigerator? I wonder, really, can the refrigerator be frost free?
The refrigerator is divided into direct cooling type and air cooled typeMostly straight cooling typeThe air cooled refrigerator has a small fan, which is cooled by cold air. Frost free. The disadvantage is that the food is dried too quickly. Excessive water loss.
Furthermore, the power consumption of frost free refrigerator is great, compared with the general direct cooling refrigerator, its power consumption per day will generally be more 2-3, and the general price level is relatively high, the most expensive a refrigerator in thirty thousand or so, it seems a bit beyond the general consumption level of family.
The main refrigeration modes of the refrigerator are air cooling, direct cooling and mixed cooling. Frost and frost are mainly determined by refrigeration methods. Air-cooled refrigerator no cream, because it is arranged in an evaporator, then each position of cold air through the fan and air duct to the refrigerator, due to direct contact with food warming on evaporator, the evaporator can be short by heating system, defrosting refrigeration immediately after recovery. Because of its hidden inside the fridge evaporator, so we can't see it produced by frost, but in this process, due to wind speed, air convection intensity and food in the refrigerator is large, water evaporation is very fast, it is easy to dry food, the refrigerator is clean, but the food fresh-keeping refrigerator the fall is not good, carefully taste, rather the taste.
In fact, about the frost, frost free refrigerator has a long-standing "frost refrigerator," the argument is not accurate, the frost is a phenomenon in the refrigeration refrigerator in the process, rather than a technical concept and no frost opposition.
