1, refrigerator is a tool to provide food preservation, different foods need different preservation temperatures, so the temperature of refrigerator should be set according to the types of foods stored. For example, green leafy vegetables 12 degree, tropical fruits 10 degree, cooked food 8 degree, beer and beverage 4 degree, fresh meat-18 degree, fish and shrimp 0 degree, etc., in principle, it has nothing to do with the season.
2. The temperature range of the freezer compartment of the refrigerator is -4~-24 degrees (three stars-18 degrees, four stars -24 degrees), and the temperature range of the freezer compartment is 5~ 15 degrees. When the mechanical thermostat is adjusted, the freezing room temperature and the refrigerating room temperature change at the same time.
3. When the ambient temperature is higher than 30 degrees in summer, the set temperature should be raised a little, in order to prevent the compressor from not stopping, resulting in serious freezing of the refrigerator, which is to sacrifice the function of the refrigerator to ensure the normal use of the refrigerator.

Refrigerate food.
The common cold storage temperature of food in refrigerator is 4 to 8℃. In this environment, the growth rate of most bacteria will slow down. However, some bacteria are psychrophilic, such as Yersinia and Listeria, which can grow and multiply rapidly at this temperature. If you eat food infected with such bacteria, it will cause intestinal diseases.
Don't store too much food in the refrigerator, which will make the external temperature of food low and the internal temperature high, which will lead to deterioration. Suitable for storing foods with strong antibacterial properties, such as pickled vegetables, jam, sesame paste, sour food and condiments, which can be stored for 2 months.
Because the refrigerator door is often opened, warm air will enter, so it is the most unsuitable place to store perishable food, such as unsealed hot meat and milk. Suitable for storing hot meat, bacon, yogurt and hard cheese. Unsealed meat should be eaten before the shelf life. Once unsealed, hot meat can only be kept for 3 ~ 5 days; Bacon and hard cheese can be kept for 3 weeks. ?
Lower floor of the cold storage room: it can store foods that need to be heated quickly, such as leftovers, cooked eggs, fish and so on. In addition, leafless vegetables and fruits that are easily frostbitten are also best stored here. Cooked eggs can be stored for 7 days: leftovers should not exceed 3 days, leftovers should not stay overnight (leafy vegetables should be eaten at one time, not left), and once they feel abnormal, they should be thrown away;
Fresh fish can only be refrigerated in the refrigerator 1 day, and cooked fish should not exceed 3-4 days. Located at the bottom of the cold storage room, with the highest humidity, it is suitable for storing vegetables, such as green leafy vegetables, peppers and broccoli. This kind of food can be stored for about 1 week at most.
