It is understood that most of the water vapor comes from the air, and when people store food and open the refrigerator, the indoor air and the gas in the refrigerator are exchanged freely, and the humid air in the room quietly enters the refrigerator. There is also a part of the moisture from the food stored in the refrigerator, such as cleaned vegetables and fruits in the crisper box, the water in the vegetables and other foods evaporates, and condenses into frost after being cold.
Especially in summer, the indoor temperature is high, the humidity is high, and the temperature difference between the room temperature and the temperature in the refrigerator is large. When the refrigerator is opened, a cool air flows from the inside out, and the indoor air burrows into the refrigerator. After a short time, a layer of hoarfrost appears on the front wall of the refrigerator.
It has also been found that even if nothing is in the refrigerator, a thick layer of frost will form in the refrigerator that is often opened, which shows that a large part of the moisture in the refrigerator comes from the moisture in the air.
I would like to ask. Aren't the few upstairs icy watermelons?
Wash the watermelon after ice before eating? Or do you eat it straight?
If you are washed and eaten when I didn't say. If you eat it directly.
According to you. It's time for you to change your habits.
However, it is also not good for the landlord to drink frost water.
It's better to wrap it in a glass of water, and ice is suitable.

Mineral water does not freeze in the refrigerator, and the temperature in the freezer is below freezing, so it freezes.

When the freezer is opened, the temperature difference between the inside and outside causes air convection, so that the cold air inside produces small water droplets attached to the refrigerator wall, forming frost under the action of freezing, and ice is formed over time; When putting the ingredients, put the outer packaging into the freezer with moisture, quickly transfer the food in the freezing area to the fresh-keeping area, and then put a basin of boiling water boiled in advance into the freezing area, after 20 minutes, the ice will melt and fall off, and then clean it with a clean rag, and finally, the thing can be returned to its original place. The freezing in the refrigerator is caused by the alternation of cold and heat, and the temperature in the room rises as the summer comes. Every time the refrigerator door is opened, the cold air meets the hot air and the draft air is disturbed, and after the refrigerator door is closed, it freezes due to the low temperature.
<> direct-cooled refrigerator, consisting of an evaporator.
Refrigeration is carried out, and the evaporator is in the freezer, in direct contact with the inner wall of the freezer for heat exchange. These evaporators are composed of S-shaped refrigeration coils, and the cold air from the compressor flows through the pipes, so the temperature of the pipes is very low, we only need to empty the food in the refrigerator, we can find a foam box, put the frozen food in the foam box, and then empty the refrigerator, unplug the refrigerator power, open the refrigerator door, let the ice in the refrigerator melt by itself, and clean it! The freezer compartment of the refrigerator freezes and the most essential reason is the humidity of the air.
Large, after entering the refrigerator freezer roommate ridge, it condenses into water, and then freezes. This phenomenon is more obvious in traditional direct-cooling refrigerators.
He first got through the pipe, there was a small hole in the refrigerator freezer, there was dirt in it, and the water flowed out, and he found it in time, just poke it with a thin wire. Frequent opening and closing of the refrigerator door will cause hot air to enter the refrigerator and encounter cold air to form water vapor.
Causes icing. Above the refrigerator room, there is a switch under the indicator light, which adjusts the temperature inside the refrigerator according to the changes of the four seasons, and hangs 3 gears for daily use, 2 4 gears in summer, and 4 6 gears in winter! As long as you follow the instructions for use of the refrigerator, there is generally no major problem.

When the temperature is below zero in the refrigerator, the water does not necessarily freeze when it is under zero, and it will freeze at the moment when the water is taken out due to the difference between the water temperature and the surrounding temperature.
-
Because the water in the refrigerator is at the boundary point, when it is just taken out, because of the high temperature of the buried closed boundary, it may appear that it will freeze immediately.
-
In fact, because the temperature difference is too large, they are actually not suitable at the beginning, so it will cause some icing code phenomenon, which is relatively normal and is also a physical principle.
-
The change of water in the refrigerator every two hours is that it will turn into ice. Under a certain pressure, when the temperature of the liquid has been lower than the freezing point of the liquid at the pressure, and the phenomenon that the liquid wheel is still not condensed is called the supercooling phenomenon of the liquid, the liquid at this time is called the supercooling liquid refrigerator, which is a kind of refrigeration equipment that maintains a constant low temperature, and is also a kind of civilian product that keeps food or other items in a constant low temperature cold state. There are cabinets or boxes that freeze through compressors and ice machines, and storage boxes with refrigeration devices.
Precautions for refrigerator useIt mainly depends on the temperature of the refrigerator and the amount of water, if the temperature of the refrigerator is about minus 10 degrees Celsius, put a glass of 100 ml of water about empty, and it can be frozen in two hours; If there is a lot of water, it will take longer. When using the refrigerator, if the user feels that there is a peculiar smell in the refrigerator, he can put a disposable cup containing Supinpai powder in the refrigerator, or put some maifan stones to remove the peculiar smell.

Look at you put **, put it on the top and it won't freeze, and it will freeze on the bottom.

1. First of all, dredge the drainage holes.
The drainage hole of the refrigerator refrigerator is generally located at the bottom of the inner side of the refrigerator, and we can generally see it after taking out the partition basket in the refrigerator. This is just handled according to the actual situation of your own refrigerator.
2. Check the tightness of the refrigerator door.
The tightness of the refrigerator door directly affects the refrigeration effect of the refrigerator and whether it can save electricity and energy. According to the above introduction, if the door is not closed tightly, it will cause the freezer compartment to freeze. So we should pay special attention.
The main thing is to check the sealing strip and magnetic strip of the refrigerator door, these two things, if you use them for a long time, it is recommended to buy the same model to replace. For the deformation of the refrigerator door, first of all, we check whether his hinges are loose, to see if the sealing of the door is smooth, we are afraid that it is not easy to repair, so it is recommended that professionals repair, but this is generally not deformed, as long as we usually do not open and close the refrigerator door by brute force, when carrying the refrigerator, remember to fix the refrigerator door. Also, when storing food in the refrigerator, don't overdo it.
Ensure the tightness of the refrigerator door to ensure that the refrigerator saves electricity and energy, and the refrigerator will not freeze.
3. Store food reasonably.
As we said above, don't store too much food in the refrigerator, this is one point, and then it must be stored after cooling outside, and for some foods with large moisture content, we must pay attention to sealing, you can use special fresh-keeping boxes or plastic wrap and fresh-keeping bags, which can prevent cross-smell and good moisture emission. We should also note that proper storage of food can also greatly reduce the phenomenon of freezing and water storage in the refrigerator.

1. The door seal is not tight, resulting in overheating of the air at the door, and the back is too cold and freezing. 2. The gear is too high, resulting in a long start-up time and a short shutdown time. 3. Excessive storage of food causes poor air convection in the refrigerated room, high temperature at the door and low back temperature and freezing.
4. The moisture content of stored food is too high and causes freezing. 5. The refrigeration temperature is adjusted too low, causing the water vapor in the refrigerator to condense into ice and adhere to the back wall of the refrigerator. 6. Is the drainage hole at the bottom of the refrigerator room blocked, sometimes the drainage hole is blocked, and there is ice if there is too much water.
Suggested Treatment:
1. Skillfully use plastic book film to solve the problem. Every time you use the refrigerator, apply a layer of plastic film, tear off the plastic wrap to quickly defrost, and then paste the plastic wrap after the completion of the wedding company, so that the defrost only takes two minutes.
2. Apply vegetable oil. Applying a layer of vegetable oil to the aluminium walls of the refrigerator crisper room can easily peel off the ice cubes, as the oil beads can block the suction between the ice cubes and the walls of the refrigerator.
3. The fan is wonderful. By using an electric fan to blow air in the refrigerator, the ice will melt faster and it will be easier to de-ice.
4. Frequent frosting. When using the refrigerator at ordinary times, it is necessary to defrost frequently, which not only prevents the refrigerator from freezing in the fresh-keeping room, but also saves more electricity.
5. You can adjust the temperature of the refrigerator to the 3 position, and then evenly apply cooking oil on the back wall of the refrigerator, so that it is not so easy to frost.
Overnight boiled water is drinkable. Some people think that boiled water cannot be drunk overnight for two reasons: first, a large number of bacteria are present in it. >>>More
Yes, but it is not recommended to put it directly in the refrigerator from the perspective of the life of the refrigerator or the deterioration of the substance. It is recommended to wait until the boiling water has cooled naturally to room temperature before putting it in the refrigerator for refrigeration or freezing, otherwise it will shorten the life of the refrigerator. >>>More
You can't drink water if it's not boiled.
Causes: Because the chlorine in tap water can interact with the residual organic matter in the unboiled water, the risk of bladder cancer and rectal cancer increases. >>>More
