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.

The refrigerator has a firecracker and a fixed frequency. You need to choose carefully when you buy. The fixed frequency refrigerator will have a fixed setting. Once it reaches the set value, it will stop working, and when the temperature changes, it will start working again. And it is easy to destroy the freshness of the food. The inverter refrigerator is more flexible and will be adjusted at any time to ensure a balanced temperature.
