Have you encountered such a problem: the refrigerator gear in the end is the larger the number of the larger the gear, or the smaller the number of the smaller the smaller the gear? In fact, the core principle of the refrigerator gear is: the larger the number, the lower the internal temperature of the refrigerator, the more hard the compressor work.

1. Gear principle

①. Extreme modes for gears 0 and 7

Gear 0 represents "standby mode", the compressor completely stops running, suitable for short-term power-off cleaning or long-term out energy-saving scenarios.

The 7th gear is the "strongest refrigeration mode". The compressor continues to run at high load, which is suitable for rapid cooling scenarios. However, long-term use will cause freezing of the refrigerator compartment and frostbite of food materials, and the overload operation of the compressor will shorten the service life.

② Dynamic adjustment mechanism of 1-6 gears

The middle 1-6 gears monitor the temperature in the box in real time through the NTC temperature sensor, and dynamically adjust the working time of the compressor. The temperature of the refrigerator compartment can be as low as 2-4 ℃ when the refrigerator is adjusted to 7 gears on the market.

2. Adjustment logic

①. Ambient temperature effect

When the ambient temperature exceeds 30 ℃ in summer, it is recommended to adjust to 4-5 gears to avoid the surge of energy consumption caused by frequent startup of the compressor.

When winter is lower than 10 ℃, adjust to 3-4 gear.

②. Food type adaptation

The storage of green leafy vegetables in the refrigerator compartment should be kept at 4-6 ℃, corresponding to 3-4 gears. Meat in the freezer compartment should be below -18 ℃, corresponding to 6-7 gears.

3. Sub-regional regulation

①. Refrigerating compartment regulation strategy

It is recommended to set it in 2-4 gears to keep vegetables fresh and avoid frostbite of fruits and vegetables.

②. Freezer compartment regulation strategy

5 gears are sufficient at no load, and 6-7 gears should be adjusted to ensure quick freezing at full load. Some high-end refrigerators are equipped with "intelligent mode", which can automatically adjust according to the type of food, but manual intervention can still improve the preservation effect by 30%.

4. Seasonal adjustment

· Spring temperature is moderate, 3-4 gear for the golden range;

· High temperature and high humidity in summer, it is recommended to gear 4-5 and cooperate with "quick cooling mode";

· Autumn turns cool, 3 gear can be;

· In winter, when there is heating in the north, it still needs 4 gears, and when there is no heating in the south, it can be reduced to 2-3 gears.

5. Special Scene Response

· Power on again after the power failure, should first be adjusted to 0 static 30 minutes, and then gradually rose to 3 gear;

· When a large amount of hot food is placed, it can be temporarily adjusted to the 7th gear to accelerate the cooling, and the original gear can be adjusted back after 2 hours;

· When going out for a long time, adjusting to 1st gear can not only maintain basic refrigeration, but also save 50% energy consumption.

6. Clarification of Misunderstandings

· Misunderstanding 1: summer must be adjusted to 7 gear. In fact, 7th gear will cause the compressor to run continuously, noisy and accelerate equipment aging.

· Misunderstanding 2: the lower the gear, the more power saving. Although the 0 file saves electricity, long-term non-shifting will lead to food deterioration and waste.

Conclusion

Grasp the underlying logic of refrigerator gear adjustment, from energy saving and cooling in summer to low temperature compensation in winter, from high humidity protection of leafy vegetables to micro-freezing and fresh meat, so that the refrigerator can truly become a cold chain housekeeper for family health.
