Cause analysis and solution of freezing in freezer of refrigerator

Refrigerator, a refrigeration equipment that keeps a constant low temperature, is also a civilian product that keeps food or other items at a constant low temperature. There are compressors, ice makers, cabinets or boxes for refrigeration, and there are storage boxes with refrigeration devices in the boxes. The volume of domestic refrigerators is usually 20 ~ 500 liters. 19 10 the world's first compressed refrigeration household refrigerator came out in the United States. 1925 Lido Company of Sweden has developed a household absorption refrigerator. 1927 the general electric company of the United States has developed a fully enclosed refrigerator. 1930, air-cooled continuous diffusion absorption refrigerators with different heating methods were put on the market. 193 1 year, a new refrigerant freon 12 was successfully developed. Domestic thermoelectric refrigerators began to be produced in the second half of 1950s, and refrigerators began to be produced in China in 1950s. Then the refrigerator will have some faults after being used for a long time. For example, the problem of freezing in the freezer is a problem that many people encounter. In fact, it is not difficult to solve this problem. Next, I'll tell you what to do and why the freezer of the refrigerator freezes. I believe that after reading the following introduction, everyone will be suddenly enlightened.

Causes of freezing in freezer of refrigerator

1. The air humidity in the freezer is relatively high, but the temperature of the evaporator in the refrigerator is relatively low, so the water vapor in the freezer will condense on the back wall to form ice.

2. After the temperature of the cold storage room drops, the ice in the back wall of the cold storage room will melt into water and flow out through the drainage hole. However, the drain hole of the refrigerator is blocked or set in the wrong way, which leads to poor water flow or incomplete ice melting, which will lead to freezing in the refrigerator freezer.

3. The improper closing of the refrigerator leads to the condensation of water vapor in the air.

Solution of freezing in freezer of refrigerator

1. Before putting in the frozen food, coat a layer of plastic film on the wall of the freezer, which is easily attached by the cold air in the freezer, and then put in the food for freezing. When thawing is needed, frozen food will be quickly moved into the freezer for temporary storage. As long as the plastic film in the freezer is torn off, the frost will melt quickly, and then the shaken film will be attached, and the food can be frozen again. It takes only a minute or two before and after, which saves time, trouble and electricity.

2. After each defrosting, dry the freezer with a towel, and then coat a layer of vegetable oil on the surrounding aluminum wall. The next time the frost comes, the suction between the frost and the refrigerator wall is greatly reduced because it adheres to the oily refrigerator wall, so you can easily peel off the lumps without much effort.

3. Always check whether your refrigerator door seal is sealed. It will exchange heat and cold to produce convection and moisture.

4. Don't put food that hasn't been thoroughly cooled. Because food will release latent heat when it is cold, and moisture when it is hot, the refrigerator is easy to freeze.

It's best to wrap the food to be put in a plastic bag, so as to lock some water.

6. Don't put too much food. The more food, the more water.

7. The refrigerator temperature should not be set too low. The temperature of the refrigerator should be set between 4-8 degrees. If the thermostat is mechanical, the gear should be adjusted reasonably according to the seasonal temperature. The gear should be adjusted to 1-2 in summer, to 3 in spring and autumn, and to 4-5 in winter. The temperature of the freezer should be kept at about minus 18 degrees, and the temperature of the freezer should be between 0- 10 degrees, preferably between 4-8 degrees.
