What is the best way to freeze the refrigerator?

The term "refrigerator ice blockage" may not be easy to understand, generally the compressor and pipeline can only be frozen due to frost hanging on the outside for a variety of reasons, and if it is not defrosted in time, in addition to the pipeline, other places will freezeQuestioner 512531088 do you want to ask if the internal pipes, frame, freezer, etc. of the refrigerator are frozen? How do I de-icing ???

If yes, I will press this question for you for your reference: remove frosting (freezing), new refrigerators have a defrost function to solve according to the manual, my refrigerator is old-fashioned and does not have an automatic defrost function. Method 1 in this situation: Turn off the power, take out a few freezer drawers and stack them, let them stay as cold as possible for a little longer, and then spray the frozen area with tap water (no chemical agents can be used.

You can't beat it with an iron tool, you can use a bamboo rice spatula to help eradicate it), wipe it with a towel while spraying, especially pay attention to the fact that there are a lot of thin pipes in the refrigerator, and you need to be patient to operate! The whole time takes about an hour, and the frozen things that are taken out will basically not melt because of this time in the ice box.

Ice blockage is due to the mixture of air in the refrigerant, when the temperature reaches a certain level, the air in the tube will condense into ice, resulting in ice blockage.

Generally at an expansion valve or capillary. You are. It is impossible for the air conditioner to freeze under normal circumstances, and the temperature is not so low.

There may be a little frost after the capillary expands, but not a lot. When the pressure of the system is almost stable, check that there is a leak in the low-pressure return pipe, and when the system has a leak, and when the pressure in the pipe is lower than the atmospheric pressure, the air will be sucked in. If there is no leakage, it means that the vacuum is not pumped clean during installation, and the desiccant of the cold storage of the low-pressure pipe should be removed, or a filter drier should be installed at the high-pressure end.

The low-voltage end is very susceptible to moisture. Drain F directly from the high voltage side in the system. Then revacuum.

When vacuuming, it is best to have a fluoridation tool with a table. When the vacuum is pumped to negative pressure, it will be pumped for a longer period of time, and the time depends on the large amount of water in the pump. A 2-liter pump generally takes a few minutes.

When adding fluorine, you should pay attention to it, be sure to close the meter valve, take down the tube and install it when connecting the fluorine altar, open the valve of the fluorine altar a little bit, and let the fluorine be discharged at the same time as the discharge and then install it at the meter interface, so as to avoid the air in the fluoride tube from entering the system again.

Add fluoride. Power is sent and done. As long as there is no air in the pipe, ice jamming will not occur. Your approach can only treat the symptoms, not the root cause. Note: Be sure to pump well when vacuuming, it doesn't matter if the time is a little longer.

The easiest way to do this is to add "methanol". However, this is not recommended as it will shorten the life of the refrigerator. It is best to clean the entire refrigeration line system with nitrogen and replace the filter with a new one. In this way, the original performance of the refrigerator can be guaranteed.

Ice blockage: Generally, there is moisture in the refrigeration pipe, resulting in blockage, and the ice blockage is generally concentrated in the upper part of the filter. It is recommended to ask the customer service staff to check it.

1. Refrigerant emission and dehumidification methods. For refrigerator ice jams with severe ice jams, run belt conveyors. Before the ice cubes appear, the capillary tube attached to the end of the filter drier is cut off by a sharp cutter, and the refrigerant is rapidly released by pressure.

At this point, a large amount of water can expel fluoride. By vacuuming, heating the pipe wall, etc., the water in the machine can be quickly discharged.

2. Heating and dehumidification. After the fluoride** or lights out, continue to turn on the compressor to increase the temperature, and put an extra pot of boiling water in the freezer. The hair dryer constantly heats the condenser.

After some time, the water is drawn into the process tube, boiled in a vacuum of about 30 degrees, and evaporates. In this way, the water vapor will be continuously extracted from the machine, thus achieving the purpose of de-icing from the machine.

3. Drying, filtration and dehumidification method. After heating the compressor, connect the filter drier to the capillary end, drill a 1mm hole in the capillary and filter screen, and then heat the filter drier, and the water is continuously discharged from the small hole under the pressure of the compressor. The process piping is injected with fresh air that has been filter-dried.

Then replace the filter.

The refrigerator leak caused an ice blockage, and it is easy to teach you to deal with it in this way, basically all at once.

If the refrigerant used in the freezer is R12, it should be the refrigerant or there is moisture in the pipe, in this case, you can fill 1-2 ml of methanol from the infusion tube before filling the refrigerant, and then fill the refrigerant, which can effectively prevent the failure of ice blockage. In addition, changing the filter is also an effective way to prevent ice blockage.

Is your capillary "ice blockage" or "dirty blockage".

The phenomenon of ice blockage is that as soon as the machine is turned on, the refrigeration evaporator part begins to receive frost, and slowly the frost melts away, and it is no longer refrigerated. The same situation occurs again after the shutdown and then the start-up. Explain the low pressure leakage, find someone to detect the leak, blow nitrogen, and change the filter.

The phenomenon of dirty blockage is that the refrigerated evaporator is not frosted at all, and the refrigerator is not refrigerated at all. The temperature of the condenser and the compressor are very high, it is relatively hot, and after a long time, the compressor should be shut down with thermal protection. Find someone to cut the filter and capillary**, blow nitrogen, and change the filter.

Placing method, turn off the power, open the refrigerator door and leave it for three to four hours, at which point, the ice will melt into water;

2.In the refrigerant release method, the capillary tube connected to the dry filter end is sheared with sharp shear, and the refrigerant is quickly released by pressure. A large amount of water can be discharged out of the machine with fluorine, and then through vacuuming, pipe wall heating and other measures, the water in the machine can be quickly discharged out of the machine;

3.In the filter drier method, after the compressor is heated, the filter drier is connected to the capillary end, a 1mm hole is drilled between the capillary tube and the filter screen, and the filter drier is heated again, and the water will be continuously discharged from the hole under the pressure of the compressor;

4.In the ice removal method, turn off the power of the refrigerator and slowly remove the ice cubes with boiling hot water.

It could be that the fridge is clogged with some dirty stuff, and this can be solved by cleaning these dirty things clean; It may be that the drain hole of the refrigerator is damaged and the drain hole is unable to drain water, and this problem can be solved by replacing the drain hole.

1. The drainage hole below the back of the refrigerator is used to remove the condensate in the refrigerator, if the condensate drainage hole is blocked, the condensate generated by the refrigerator will flow everywhere to the inside of the refrigerator if it is not effectively discharged. If it drops on the internal parts of the refrigerator, it will damage the various parts of the refrigerator. 2. After the refrigerator drain hole is blocked, the most effective way is to use iron wire to dredge the drain hole, or you can use a pump to align the air outlet of the pump with the ability water drain and stick it tightly, hit the pump a few times, and dredge the drain by the outlet pressure of the pump.

3. When the refrigerator is usually used, the simple plastic filter originally configured at the condensate drain outlet should be installed to prevent solid substances such as food residues from blocking the drainage holes. First of all, the power should be cut off, all the food in the refrigerator should be cleaned out, and then the blocked place should be dredged to the refrigerator before it can be used normally. 4. When the refrigerator is used, it must be cleaned regularly to effectively prevent the refrigerator from being blocked.

If the freezer compartment is blocked by ice every time, then we can turn off the power, then open the refrigerator door and leave it for another three to four hours, until all the ice in the refrigerator has melted into water, at this time we can use absorbent sponges and towels to wipe the water around the refrigerator clean. Secondly, we can use scissors to cut off the capillary tube that was originally connected to the dry filter end and release the refrigerant in the refrigerator. At this time, a large amount of water in it can also be discharged out of the machine together.

We can also heat the compressor first, connect the capillary tube with the filter drier, and drill a small hole of about 1mm on the capillary, when we start to heat the filter dried, the water will continue to be discharged from the hole under the pressure of the compressor. We need to constantly inject new air into the filter, replace it with a new filter, and then fill in the small holes.

How to solve the ice blockage of the refrigerator 1. Filter drier method (1) After heating the compressor, connect the filter drier to the capillary end, and drill a 1m hole between the capillary and the filter screen. (2) Reheat the filter drier, and the water will be continuously discharged from the small hole under the pressure of the compressor. (3) Feed new air into the filter and replace it with a new filter.

4) The next step is to close the valve and let the compressor vacuum itself while heating the pipes. (5) Until the drilled hole is equal to the atmospheric pressure, no more air inlet and outlet, fill the small hole, and then vacuum, fluorine, and seal outside the machine. 2. Placement method (1) A very simple but effective way is to turn off the power, open the refrigerator door and leave it for three to four hours.

2) At this point, the ice will melt into water, so prepare an absorbent sponge or towel around the refrigerator. 3. Ice repellent method (1) First turn off the power of the refrigerator and slowly remove the ice cubes with boiling hot water. (2) The boiling water must be boiled, and then use a hot water sprinkler with slightly better quality water absorption.

3) Melt the connection between the refrigerator and the ice cubes, and the ice can be removed. 4. Refrigerant release method (1) The capillary tube connected to the dry filter end is cut with sharp scissors, and the refrigerant is quickly released by pressure. (2) At this time, a large amount of water can be discharged out of the machine with fluorine, and then through vacuuming, pipe wall heating and other measures, the water in the machine can be discharged out of the machine quickly.

1. The reason for the ice blockage of the refrigerator After the evaporator is damaged, the water molecules in the freezer and the water vapor molecules in the air are brought into the compressor after a long period of start-up (negative pressure is generated in the generator when the machine is turned on, and the atmospheric pressure brings the water molecules in the humid air into the machine). 2. Methods for judging the ice plugging fault of the refrigerator 1. The phenomenon of defrosting occurs periodically defrosting and frosting, that is, the temperature decreases and causes blockage, and the ice blocked by the capillary nozzle melts when the temperature rises after the blockage; After the capillary tube is unobstructed and throttled refrigeration, the temperature decreases and becomes clogged, and so on, so that the refrigerator cannot work normally. 2. In the initial stage after the compressor is started, there will be no ice blockage due to the high temperature after throttling, and the refrigerant can maintain the circulation.

When you open the freezer door, you can hear the flow of refrigerant after throttling, the condenser is heating up, the evaporator is frosting, and the pressure gauge set for repair indicates positive pressure. 3. Treatment method of refrigerator ice blockage 1. When vacuuming to eliminate the ice blockage fault, the refrigerant should be discharged first. The refrigeration system is vacuumed and filled with dry nitrogen.

Start the compressor to run until the dry nitrogen absorbs the moisture before vacuuming, and so on several times. The refrigeration system should also be replaced with a new filter drier when it is restored. During the filling process of high-quality refrigerant, the filter should also be dried to absorb as much water as possible from the refrigerant.

2. Before the drying refrigeration parts are loaded into the system, they must be dried in a constant temperature drying oven. For complex parts, such as a fully enclosed compressor, it is necessary to bake for 816 hours in a constant temperature environment of about 105 (slightly higher than the boiling point of water at local atmospheric pressure) to allow the water to vaporize and discharge. However, the temperature should not be too high, as temperatures above 120 will damage the motor insulating medium.

Generally, parts with simple structure can be baked for about 4 hours. If possible, vacuuming while baking can reduce the pressure or temperature, as this will lower the boiling point of the water and facilitate the discharge of water.
