In summer, refrigerators are usually driven to gear 2 to 3. The lower the gear, the lower the temperature of the freezer, and the maximum power consumption.
In summer, the refrigeration temperature of the refrigerator should be better controlled between - 2 ℃ and - 8 ℃, and the freezing temperature should be better adjusted between - 18 ℃ and - 24 ℃. If there is a shift button, it is generally adjusted to gear 2 to 3.
When we adjust the gear, we'd better not set it too low. This will cause the refrigerator compressor to be in operation all the time, which will consume a lot of power. Long term operation will also affect the service life of the refrigerator. When we adjust the gear, we need to consider the temperature difference inside and outside the refrigerator. The smaller the difference, the less power consumption.
