Which is better, air-cooled frost-free refrigerator or direct-cooled refrigerator?

Air-cooled frost-free refrigerator is good.

1. Refrigeration effect and temperature uniformity: The air-cooled frost-free refrigerator adopts air cooling technology, and cold air circulates into the refrigerator through the fan, so that the temperature distribution inside the refrigerator is more uniform. This refrigeration method not only avoids the problem of food freezing, but also ensures that the temperature in every corner of the refrigerator is kept within the ideal range. The refrigeration mode of direct-cooling refrigerator is relatively simple, mainly by directly absorbing heat from evaporator to reduce the temperature. However, because there is no fan for air circulation, the temperature distribution inside the refrigerator may be uneven, sometimes causing food to freeze.

2. Easy maintenance and defrosting function: the air-cooled frost-free refrigerator has automatic defrosting function. Due to the circulation of cold air, there is no frost in the refrigerator, which avoids the trouble of manual defrosting. This not only saves users' time and energy, but also makes refrigerator maintenance more convenient. The direct-cooling refrigerator has no automatic defrosting function. After a period of use, frost may form inside the refrigerator, which requires the user to defrost manually. This increases the difficulty and inconvenience of maintenance.
