Which refrigerator is better

The two cooling methods of the refrigerator are good. From the perspective of defrosting, the air-cooled refrigerator will perform better, because the air-cooled refrigerator uses forced air convection to cool the temperature. It reaches the expected temperature, and it is not easy to frost. The direct-cooled refrigerator absorbs heat by the evaporator to reduce the temperature, and it is easy to condense the frost.<img src="{{media url=&quot;magefan_blog/Which_refrigerator_is_better.jpg&quot;}}" alt="" />
