What's wrong with the refrigerator not keeping fresh?

First, what is the problem that the refrigerator does not keep fresh but freezes? 1, which is caused by the aging of the refrigerator. Because the refrigerator has been used for a long time, the sealing strip of the refrigerator door will deform and age, and it will also cause the refrigerator to freeze. At this time, we can turn off the power of the refrigerator first, and then check the fresh-keeping room. At this time, we will find a leaking round hole in it, then find a thin plastic pipe, insert it into the round hole and blow it with our mouth or pump. 2. Or find some thin sponges, then put a flashlight in the refrigerator to turn it on, close the refrigerator door and put the sponges in the sealing strip where we can see the light until we can't see the light. Second, the refrigerator purchase skills 1, refrigerator size When buying a refrigerator, the size of the refrigerator must consider the needs of your own home. Don't buy a big refrigerator, because judging from the eating habits of Chinese residents, the average household refrigerator is about 50 liters per person, so we say that a family of three or four can consider choosing a refrigerator of about 150-220 liters. 2. The energy-saving refrigerator with the energy-saving and energy-efficiency label of 1 or 2 has stronger thermal insulation performance, so it will consume less electricity. Let's take a 268-liter energy-saving refrigerator as an example. During its service life, it can save about 2000 yuan in electricity bills. If all the newly updated refrigerators in the country adopt energy-saving refrigerators every year, the national carbon dioxide emission can be reduced by 12 1 10,000 tons a year, and it is saved in the freezer.
