What is the temperature at which the refrigerator keeps fresh?

1. What is the fresh-keeping temperature of the refrigerator? In general, the temperature of the fresh-keeping room of the refrigerator should be controlled between 0- 10, and not higher than 10. Once it is higher than 10 degree, it is likely to affect the fresh-keeping effect of the refrigerator. 2. If there are vegetables in the refrigerator that need to be stored for a long time, it needs to be lowered to 4~8 degrees. For example, putting leftovers in a refrigerator at 0~ 10 degree can't produce fresh-keeping effect. At this time, it needs to be adjusted to 4~8 degrees. If vegetables are kept in the refrigerator for a long time, we need to adjust it to 4~5 degrees. If there are not too many people at home and there is more food in the refrigerator, try to adjust it to 4~5 degrees. It doesn't matter if it is lower, but it can't be too high. Many refrigerators in people's homes are mechanical refrigerators. If you use a mechanical refrigerator, you should adjust it to 2~3 in summer. If it is a household refrigerator, it should be set to 1~2. Second, what are the precautions for purchasing a refrigerator? 1, because when we buy a refrigerator, we must be clear about the brand of the refrigerator, and choosing the right brand will play a certain role in the later use. When buying a refrigerator, we are much more sanitary than ordinary refrigerators, so you can choose first.
