Refrigerator freezer is mostly used to store some fresh vegetables and fruits, which plays a fresh-keeping role. These items have strict requirements on temperature. It is best to adjust the temperature of the refrigerator to 2-8 degrees, and the temperature within this range can meet the needs of most fresh-keeping items. You can put food in the refrigerator for 24 hours, then take it out and put it at room temperature. If the food doesn't feel cold, it proves that the set temperature is too high, and you need to lower the temperature.
Refrigerator is a kind of refrigeration equipment to keep a constant low temperature, and it is also a civil product to keep food or other items at a constant low temperature. There are compressors, ice makers, cabinets or boxes for freezing, and storage boxes with refrigeration devices in the box. Household refrigerators usually have a capacity of 20-500 liters.
Matters needing attention in using refrigerator
1, we must pay attention to when using the refrigerator, don't open and close the refrigerator frequently, it will make the air outside the refrigerator flow into the refrigerator and condense into water vapor, which will cause the refrigerator to freeze.
2, in the process of using the refrigerator, try not to put hot food in the refrigerator, hot food in the refrigerator will destroy the temperature of the refrigerator, but also condense water vapor, and then the refrigerator will freeze.
3. For every 5℃ increase in the temperature around the refrigerator, its internal power consumption will increase by 25%. Therefore, it should be placed as far away from the heat source as possible, preferably in a ventilated and shady place.
4. Don't stop using the refrigerator for more than 3 months. Under normal circumstances, do not stop using the refrigerator. When it is stopped, the temperature rise will accelerate the corrosion of pipelines and affect the service life of refrigerators. If the refrigerator is not used, clean the inside and outside of the refrigerator, then open the door and put it in a clean place. Be careful not to seal it, because sealing will produce odor.
5. The refrigerator should be cleaned regularly to keep the cooling effect.
