There are many kinds of refrigerators in the market, such as mechanical refrigerators and intelligent refrigerators. If the models are different, the temperature adjustment method of the freezer will be different, as shown in the following figure:

1. If the refrigerator is a mechanical refrigerator, you can adjust the temperature control knob inside the refrigerator to about fourth gear, which is more suitable for the temperature of the frozen layer. Mechanical refrigerators are generally equipped with a temperature control knob with seven gears, which can be adjusted according to the weather temperature and your own needs.

2. If it is in summer, it is best to adjust the temperature of the freezer to "1-3". If it is in winter, it is best to adjust the temperature of the freezer to "4-5". The higher the number of gear adjustments, the lower the temperature in the freezer, and the seventh gear is the most mandatory cold gear in the freezer.

3. If the refrigerator belongs to a smart refrigerator, you can adjust the temperature in the freezer through the touch-screen button on the door of the smart refrigerator. In general, the freezing room temperature of smart refrigerator should be adjusted between minus 14 and minus 18. Most refrigerators on the market can adjust the temperature of the freezing chamber in the range of-10 degrees to -22 degrees.

4. However, the temperature adjustment range will be different for different refrigerator manufacturers, and the specific temperature should be adjusted according to the instruction manual of the refrigerator. If the smart mode of the smart refrigerator has been turned on, there is no need to manually adjust the temperature of the freezer, and the smart refrigerator will generally automatically adjust according to the actual situation of the freezer.
