Millet air-cooled frost-free and direct cooling are two different ways of refrigeration. 1. Air cooling without frost: This refrigeration method adopts air cooling technology, and circulates cold air through the built-in fan, so that the indoor air is fully circulated, and the temperature in the refrigerator is evenly reduced. At the same time, the air-cooled frost-free refrigerator is also equipped with frost-free technology, through the automatic melting and defrosting of the refrigeration cycle system, there is no frost, and the user does not need to manually defrost. This refrigeration method can keep the temperature of the freezer and the cold room stable, maintain the freshness of the food, and do not need to frequent defrost, and it is convenient to use and maintain. 2. Direct cooling: The direct cooling ice box uses the traditional refrigeration method, passes the heat conduction to the refrigeration room, and then cools through the refrigeration medium, and the indoor air circulation is poor. The direct cooling box needs to be manually defrosted regularly, otherwise the freezer will produce a large amount of frost, affecting the refrigeration effect. Direct cooling refrigeration saves electricity and cools faster, but requires frequent defrosting and maintenance.
1, the refrigeration effect is different: the air-cooled refrigerator mainly uses cold air forced circulation, and the fan air supply, so the refrigeration speed is fast, the temperature balance is better, of course, there will be energy consumption and noise is slightly higher, the direct-cooled ice box is mainly by natural convection, the temperature balance is relatively worse, the cooling speed is slightly slower, but the refrigerator refrigeration is more power-saving.
2, the refrigeration capacity is different: the air-cooled refrigerator and the direct-cooled ice box refrigeration capacity cut-off point is about 300 liters, the refrigeration of the air-cooled refrigerator is more dominant, its refrigeration capacity is more than 300 liters, and the direct-cooled ice box room to do 3 has basically reached the limit, so its refrigeration capacity is often lower than 300 liters.
Air-cooled no frost indicates that there is no frost in the freezer, and direct cooling indicates that there is frost in the freezer
