Abstract
Provided are a control method for a refrigerating and freezing device, and the refrigerating and freezing device. The refrigerating and freezing device includes a cabinet provided with a groove communicating with a surrounding environment and sunken inwards, and at least one fan for promoting air of the surrounding environment to flow into the groove. The control method includes: judging whether a temperature in the groove is less than or equal to a dew point temperature; and if yes, controlling the fan to operate at a first preset rotation speed. The temperature in the groove is increased by controlling the fan to operate to introduce hot air of the surrounding environment into the groove when the temperature in the groove is less than or equal to the dew point temperature, which avoids condensation in the groove and improves safety and reliability of electrical parts in the groove.
