Because the general refrigerator freezer has a temperature adjustment button 1-7, which can be adjusted to 2-3 in summer and 6-7 in winter.
The main reason is that the outside temperature will affect the performance of the refrigerator, so the differential shift makes the inside and outside of the refrigerator have a good integration.
Therefore, it is more appropriate to keep it at about 5-8 degrees. The freezing room temperature is related to the quality of the refrigerator itself and external factors. Because the refrigerator is not easy to freeze and frost, it can also maximize its energy efficiency.
The freezer plays the role of freezing. If the temperature is too low, it will easily freeze into ice, and if the temperature is too high, it will not work well. So just keep the temperature of the freezer at MINUS 18 degrees Celsius. In this case, the refrigerator is not easy to frost, but also can maximize its energy efficiency.
Extended data:
Regular and proper maintenance can prolong the service life of refrigerator. Be sure to unplug the refrigerator before maintaining it.
1, often clean the dust on the condenser and compressor at the back or bottom of the refrigerator. You can use a vacuum cleaner or brush to remove dust. Be careful not to wipe the dust on the refrigerator and compressor with a wet cloth.
2. When the refrigerator is out of service for a long time, you should first cut off the power supply, take out all the food in the refrigerator, clean the inside and outside of the refrigerator, and open the door for several days in a row to make the refrigerator fully dry and dispel the peculiar smell in the refrigerator.
3. Check the drain pipe. If the drain pipe is blocked, water will leak into the refrigerator. Poke the drain pipe with a wire to remove the things accumulated on the drain pipe.
4. Don't neglect the cleaning of the door sealing strip. Dilute the bleach with 10 times of water, and then dip it in a toothbrush to clean it. Finally, rinse the bleach with water. The adhesive tape is dirty and easy to age, which will affect the tightness of the refrigerator and increase power consumption.
5. Check the vibration, noise and temperature of the compressor. When touching the compressor shell during operation, there should be no obvious vibration, and the compressor should not be started obviously during the day.
6, pay attention to check whether there is a crack in the power cord, to prevent leakage.
7. Wash and dry the inside and outside of the refrigerator with warm water or neutral detergent, and open the refrigerator door for ventilation and drying for one day.
