Air-cooled frost-free refrigerator means that the internal structure of this refrigerator adopts air-cooled technology and does not need manual defrosting like traditional refrigerators. Its principle is to set an air duct inside the refrigerator to achieve the cooling effect by forcibly circulating air. At the same time, the tide in the air duct is blown dry, so as to achieve the frost-free effect.

Compared with ordinary refrigerators, air-cooled frost-free refrigerators have many advantages. First of all, because manual defrosting is not needed, the labor cost is greatly reduced. Secondly, the temperature inside the refrigerator is more uniform, and even the food placed below will not freeze because of the low temperature. Finally, due to the arrangement of the air duct, the internal space of the refrigerator is more sufficient.

But the air-cooled frost-free refrigerator also has some disadvantages. Because the cooling effect needs to be achieved by forced circulation of air, the noise is relatively large. At the same time, because there is no need for manual defrosting, excessive frost accumulation in the refrigerator may lead to abnormal operation of the refrigerator, thus reducing its service life.

In a word, air-cooled frost-free refrigerator is an efficient, convenient and economical refrigerator type, but it also needs reasonable use and maintenance.
