Question

Is there a fan in an air-cooled refrigerator

Time:2020-05-13Views:

There must be no frost in the air-cooled refrigerator?
The traditional direct cooling refrigerator needs regular manual defrosting, which is also a problem that has been puzzling the refrigerator users, and the application of air cooling technology in the refrigerator solves the problem of frosting. At the same time, the easy to spread slogan of "cold without frost" has been exposed frequently, which makes consumers mistakenly believe that the air-cooled refrigerator will not frost.
Careful users will notice that some refrigerator enterprises will use "all air cooling" to describe the air cooling technology of their own refrigerators, and the meaning of "all air cooling" is very simple: each storage room of the refrigerator (refrigerated room, variable greenhouse, freezer) adopts the air cooling technology, which can ensure that each storage room will not frost on the inner wall of the refrigerator.

The refrigerator of the hybrid refrigerator: the back still produces frost
But many refrigerators adopt the mixed refrigeration technology, usually the refrigeration room is designed for direct cooling, and the refrigeration room is designed for air cooling; if it is used for a long time, there will still be frost on the wall of the refrigerator refrigeration room, that is to say, the "frost free" effect claimed by the actual mixed refrigeration refrigerator cannot be fully realized. Therefore, in order to achieve the "completely frost free" effect, consumers need to distinguish the "hybrid refrigeration refrigerator" and "all air cooling refrigerator" products.
In addition, the air-cooled refrigerator will not frost on the inner wall of the refrigerator. For the convenience of publicity, the refrigerator enterprises call it "frost free", but this does not mean that there is no frost in the refrigeration process of the air-cooled refrigerator. As the air-cooled refrigerator's internal blowing is the air flow, it will not lead to the absorption of water from the stored food and frost on the inner wall of the refrigerator, so where is the frost?

No frost on the inner wall of air-cooled refrigerator
In fact, the frost of air-cooled refrigerator almost condenses on the evaporator. The frost condenses on the evaporator is removed by thermal evaporation, that is, after the refrigerator works for a period of time, the refrigeration is suspended and the defrosting heating system is started. The condensed frost will turn into water after being heated, and then it will be discharged (or directly evaporated into water vapor) through a special pipe. This work is automatically completed by the refrigerator, and does not need manual defrosting by the user.
