The refrigerator has poor refrigeration, what s going on?

1. There is water in the system that causes blockage. Ice plugging tends to occur where the capillary and filter and the capillary enter the evaporator. All the refrigerant wattles in the system are released, the system is dried, and the fluoride is pumped out.

2. Insufficient refrigerant. It is usually caused by a leak in the pipe joint or weld. Before and after leak detection, the system is filled with nitrogen or dry air with force cm2, and the system is leak detected with thick soapy water or leak detector.

3. The performance of the compressor is reduced. Usually the discharge pressure is slightly lower and the suction pressure is slightly higher, which is caused by the wear of the compressor components after a period of use, which reduces the refrigeration cycle. Dismantle or replace the compressor.

4. The thermal insulation material has been damp for a long time, the magnetic stripe is aging, and the door seal is not tight. Overhaul and replace insulation materials and door seal magnetic strips. The evaporator has too much oil and takes up part of the evaporation area.

The outlet pipe of the evaporator slopes to the suction pipe of the compressor, so that the oil storage returns to the compressor, and if the oil storage is serious, the evaporator needs to be removed for cleaning.

The poor refrigeration effect of the refrigerator is due to the lack of refrigerant in the refrigerator after a long period of use, and the sealing strip is not tightly sealed. Repairs and replacements are required.

The refrigeration effect of the refrigerator is poor, it is recommended to check whether the refrigerator needs to add refrigerant, and whether there is a problem with the refrigerator compressor compressor.

The refrigeration effect of the refrigerator is poor, and it may be that there is a lack of that liquid, so you can find someone here to repair it to fill you with some liquid.

In general, it may be that the refrigerant is insufficient, see if there is any refrigerant liquid?

1: The compressor is aging, and the clearance volume becomes larger when the cylinder is compressed, resulting in a decrease in refrigeration capacity.

2: Refrigerant slow leakage, some refrigerators will have slow leakage due to welding or other reasons, that is, the refrigeration has leaked at a rate of several grams per year, and the refrigeration effect becomes worse after a period of time.

3: The temperature control of the thermostat is inaccurate.

A refrigeration equipment that maintains a constant low temperature, and is also a civilian product that keeps food or other items in a constant low temperature and cold state. Inside the box there is a compressor, a cabinet or box for ice making for icing, and a storage box with a refrigeration unit. The volume of a household refrigerator is usually 20 500 liters.

In 1910, the world's first household refrigerator with compression refrigeration came out in the United States. In 1925, the Swedish Lido company developed the household absorption refrigerator. In 1927, the General Electric Company of the United States developed a fully enclosed refrigerator.

In 1930, air-cooled continuous diffusion absorption refrigerators with different heating methods were put on the market. In 1931, a new type of refrigerant freon was successfully developed, and the production of household thermoelectric refrigerators began in the second half of the decade, and China began to produce refrigerators in the 50s.

1.There are too many foods in the fridge:

The fridge was stuffed with too much stuff and stuffed to the brim. Others will also put those hot foods in the refrigerator, each refrigerator has a rated capacity and power, and put too much food in it, and the load is too heavy. The refrigeration effect will definitely not be good.

2.The fridge door is not closed properly :

If the refrigerator door is not closed properly, the refrigeration work of the refrigerator compressor is ineffective, so the compressor will always work without stopping, resulting in an increase in power consumption, and the refrigeration effect of the refrigerator will also be affected, but it will not be refrigerated. If the freezer door is not closed properly, a thick layer of ice will form between the cracks in the door. This is something that everyone should pay special attention to.

3.The refrigerator does not dissipate heat well:

The refrigerator used in our family generally has condensers on both sides of the refrigerator, and the refrigerator is relatively hot on both sides when it is refrigerated. This is very unscientific. The result of this will cause the refrigerator to have a poor refrigeration effect, and the temperature will not reach the set temperature, which will also cause the load of the compressor to increase and shorten the life of the compressor.

It should also be noted that there needs to be a gap of more than 5 cm between the sides and the back of the refrigerator, so that the heat dissipation effect is better.

The refrigeration effect of the refrigerator deteriorates, which is likely to be caused by the lack of refrigerant in the refrigerator, so it is recommended to check whether your refrigerator needs to add refrigerant, especially for those older refrigerators.

The automatic effect in the refrigerator deteriorates, which is caused by the fact that the refrigerator has been in the refrigerator for a long time, and the benefits in the compressor have become less nourished.

The deterioration of the refrigeration effect of the refrigerator should be a lack of Buddha, and you should find a home appliance repairer to repair it and let him check it.

As one of the indispensable electrical appliances in modern people's family life, refrigerators have important functions such as storing food and maintaining food freshness. However, there are times when we encounter a situation where the refrigerator is not cooling or under-cooling, which is a very troublesome problem.

Here are the reasons why refrigerators are not refrigerated:

1.Poor door sealing: Poor refrigerator door sealing is one of the common causes of insufficient refrigeration. Poor door sealing will lead to the loss of cold air, which will affect the temperature inside the cold box, and over time, it will lead to a decrease in the cooling effect.

2.Refrigeration system failure: The refrigerator is made by the refrigeration system to achieve hail cooling, if the refrigeration system fails, such as refrigerant leakage, compressor damage, etc., it will lead to the reduction of refrigeration effect.

3.Improper refrigerator temperature regulation: If the refrigerator temperature is set too high or too low, it will affect the temperature control in the cold room, resulting in a decrease in the cooling effect.

4.Accumulation of dirt in the pipeline: The refrigerator used for a long time will accumulate dirt, dust, etc. in the refrigeration line, which will reduce the space in the pipeline and reduce the cooling effect.

5.Excessive use: Appliances that have been used for a long time often have various faults, and refrigerators are no exception. When the refrigerator is used for a long time, the parts in the cold storage will gradually wear out and age, resulting in the reduction of the refrigeration effect.

In order to maintain the cooling effect of the refrigerator, we need to clean the refrigerator regularly, check the door seal, and maintain the refrigeration system regularly. This not only ensures the cooling effect of the refrigerator, but also prolongs the life of the refrigerator.

1. Too many things in the refrigerator will definitely lead to too many things in the refrigerator will lead to the situation of not refrigerating, too much food in the refrigerator will lead to excessive heat load, and the compressor will continue to run, resulting in a temperature higher than the set temperature, which will lead to bacterial breeding and food deterioration. 2. Storing too much food at one time will also lead to the refrigeration effect, and will cause too much power to be lost invisibly, and a lot of additional power will be wasted invisibly.

Recommended maintenance method:

1. It is best not to store too much food at one time, because too many things in the refrigerator will lead to no refrigeration, if you want to store a lot of things, you can store them in batches, which can well reduce the overload of the Xiaoice box and avoid the situation that the refrigerator is not refrigerated, and the temperature of the refrigerator can be set to automatic adjustment. 2. Each refrigerator has a freezing capacity value, which also represents the load capacity, and the power consumption of the refrigerator filled with food has increased a lot compared to the power consumption of the empty refrigerator, so it must not exceed the load capacity of the refrigerator. 3. When storing food, it can be classified according to the category of food, which can be stored separately, which can keep the food fresh and will not affect other foods.

To adjust the cooling effect of the refrigerator, you can take the following steps:

Temperature setting: Check the temperature setting of the refrigerator, usually located inside the refrigerator or on the control panel. Set the temperature to the appropriate refrigerator and freezer temperature, it is generally recommended that the refrigerator temperature is 2-4 degrees Celsius and the freezer temperature is around -18 degrees Celsius.

Fan regulation: Some refrigerators are equipped with internal fans that help circulate air and maintain an even temperature distribution. Make sure the fan is working properly and doing the necessary cleaning and maintenance.

Proper load denuclearization: Do not put too much food in the refrigerator to avoid obstructing air circulation and refrigeration. Keep items scattered in the refrigerator and freezer compartments to ensure air circulation.

Clean the back of the refrigerator: Clean the condenser and vents on the back of the refrigerator regularly to ensure good heat dissipation and improve the cooling effect.

Avoid opening and closing doors frequently: Frequent opening and closing of refrigerator doors can lead to temperature fluctuations and wasted energy. Try to open and take out or put in the desired items at one time, avoiding unnecessary switches.

Defrost regularly: If the freezer produces ice, defrost it regularly to maintain the space and cooling effect in the freezer.

The refrigerator jujube door is not closed properly, and the refrigeration effect is poor. Or if there is food in the refrigerator, it is necessary to clean and check the refrigerator in time to prevent the refrigeration effect of the refrigerator from being affected.

You can check if your refrigerator is cooling properly:

1.Open and close the refrigerator door to see if the lights are on normally;

2.When the power supply is normal, check whether the compressor is working normally;

3.Determine whether the refrigeration system has refrigerant;

4.If the refrigerator is gradually cooled, check whether the fan is working properly.

If you can't judge the Qinyan section, you should ask a professional to repair the refrigerator, or clean the refrigerator first to see if the situation has improved.

1. Check whether the power connection is normal.

Open the refrigerator door and observe whether the light in the lower box is lit, or test it with an electric pen. If you have had a power outage in your home, then be sure to double-check whether it is a power supply problem.

2. If the power connection is normal, check whether the compressor is working.

The compressor will emit a slight vibration motor sound when working normally (if you feel the vibration of the compressor with your hands, you must be careful not to burn, because the compressor temperature is 40-50 in winter and 80-90 in summer).

3. If the compressor can work, judge whether there is refrigerant in the refrigeration system.

Let the refrigerator run for a few minutes, then unplug it and listen carefully to see if there is any liquid running in the copper tube. If not, it means that the refrigerant in the system has leaked or the compressor is no longer functional.

4. If your refrigerator is intercooled, check whether the fan is working.

Open the door of the freezer, press the button at the edge of the box mouth with your hand (this button controls the indoor lighting and stop the fan from working when the door is opened), check whether the lower fan is working, the fan does not work will also cause the refrigerator to not refrigerate.

5. The loss of refrigerant caused by the leakage of the refrigerator refrigeration system needs to be pressurized on the refrigerator refrigeration system, find the leakage point, make up the leakage point, and fill the refrigerant in the evacuation.

6. If too much food is stored in the freezer, the vent will be blocked, resulting in the cold air cannot be circulated and the condenser will be blocked. Try disconnecting the power to the refrigerator, opening the refrigerator door to allow the ice in the evaporation pipe inside the refrigerator to melt thoroughly, and cleaning the drain holes.
