What happens if the air conditioner doesn t cool for long?

1.If the fluorine leaks or there is air inside, the compressor protects it from refrigeration, finds the leak and repairs it, and re-fluorides.

2.If you add too much fluorine, you can't run for a few minutes, and the compressor doesn't protect and refrigerate, and you can release the excess fluorine.

3.Misoperation of the remote control Double-check the display on the panel against the instructions to remove.

4.Sensor Failure Replace the sensor.

5.If none of the above is true, check the voltage, capacitance and current again when refrigerating, if it is normal, it will not be refrigerated after a period of time, and it will not take long to restart the machine and refrigerate, then the compressor is faulty, and the compressor will be replaced.

First, if the new air conditioner is not refrigerated, it may be a problem with the quality of the air conditioner, please buy a brand air conditioner, at least the after-sales service is also ***.

Second, the air conditioner lacks fluorine and chlorine, that is, the lack of refrigerant, at this time the air conditioner fluoride is necessary, in this case, it is good to find the air conditioner maintenance personnel to add fluoride, but how to detect whether the air conditioner is deficient, the air conditioning maintenance center provides some methods to detect the lack of fluoride in the air conditioner.

Third, the problem of the compressor, it is very likely that the compressor is aging and the efficacy is insufficient, because the role of the compressor is the key to the refrigeration of the air conditioner, in this case, you can choose to change the compressor or buy a new air conditioner.

Fourth, the reason why the air conditioner is not refrigerated also lies in the fact that the air conditioner has not been cleaned for a long time, but how to clean the air conditioner, the external temperature is too high and many other factors, and the specific situation has to be tested by the air conditioning maintenance personnel.

Fluoride) leaks, you just go and add some points.

Turn the temperature control to 3 and try again.

The possible reason why the air conditioner does not refrigerate is that the compressor protection device trips. Compressor overload protection will trip, indicating that the system is too high-pressure, the pressure is too high, or the overheating current is too high.

Causes and elimination of high pressure and overheating:

1. Too much refrigerant. Reduce the refrigeration dose appropriately. Most of the reasons for this non-refrigeration are the air conditioners that have been used for three or four years, and most of them are also a normal phenomenon, which belongs to the normal consumption of air conditioning refrigerant (that is, we often say freon or refrigerant) due to long-term use, but this is only manifested as insufficient refrigeration of air conditioners compared with the previous normal conditions.

2. Poor heat dissipation. Check the condenser pipe for dirt and dirt and clean the condenser.

3. The pipeline system is blocked. Refer to the pressure gauge to judge, eliminate, and re-process systematically.

4. Dust and fouling of the evaporator or filter screen. The airflow becomes smaller, the system pressure and temperature are unstable, and the evaporator or filter is cleaned.

5. Fluoride deficiency is also possible. When there is a lack of fluorine, the compressor discharge temperature will overheat, causing the overheating load protection switch to trip.

Reasons why the air conditioner is not cooling.

1. Not cleaned in time. The reason why the air conditioner is not cold may be that the air conditioner has been used for a long time without being cleaned. The filter screen of the internal unit adsorbs a lot of dust, although the temperature of the indoor unit air outlet is very low, but the air is not far away, and the room circulation slows down.

2. Lack of freon. For the old air conditioner is not cooling, it may be caused by the lack of freon. Because old-fashioned air conditioners mainly rely on freon for refrigeration, the addition of freon can restore refrigeration.

3. The voltage is unstable. Especially in summer, every household will turn on air conditioners and fans, and some even turn on several air conditioners at the same time, which will cause the voltage used by the air conditioner to be insufficient, unable to drive the compressor announcement, resulting in poor refrigeration effect.

Hello, dear, I am the Q&A Lord, I received your question, and I am sorting out the answer, please wait, I will reply to you within ten minutes.

1. Freon is not enough: most of the reasons for this non-refrigeration are in the air conditioners that have been used for three or four years, and most of them are normal, and they are only manifested as insufficient refrigeration compared with the previous normal situation, and they will not be completely uncooled, because the pressure is not enough and will not be too far from the normal value.

2. The voltage of the power supply is not enough: this problem is manifested as normal air conditioning and refrigeration when the voltage is normal, when the voltage is unstable, it will affect the air conditioning when it is not refrigerated, and we must start to solve it from the aspect of providing stable voltage.

3. The power of the air conditioner is not enough: this kind of situation is easy for us to ignore, and the solution to this kind of problem is generally only from increasing the number of air conditioners; change the conditions of the environment in which it will be used; Increase the airtightness of the use environment; Reducing the heat source in the environment where the air conditioner is used is reduced.

4. The temperature of the external environment is too high: This kind of non-refrigeration is common in our outdoor units installed in a relatively closed space or the temperature around the outdoor units is too high. Then the simplest and most direct way is to change the use environment of the outdoor unit.

5. The air conditioner is not cleaned and maintained for a long time: everyone thinks that they can sit back and relax when they buy the air conditioner, but in fact, we still have to regularly maintain the air conditioner in many aspects, and the outdoor unit is the easiest for everyone to ignore, and the clean outdoor unit is easier to dissipate heat, so the use of the air conditioner must pay attention to cleaning and maintenance.

I am engaged in refrigeration maintenance, this thing is similar to the principle of refrigerators, can not be left for a long time, let the compressor start once a week, at least 10 minutes at a time, otherwise the refrigerant is easy to leak, you are no refrigerant, to pressure detection.

First of all, we have to know that the general air conditioner does not need to be refrigerated for ten years after it is bought and used.

The cooling effect is really not very good, so you can try to clean the air conditioner by yourself first, because it is likely that the air conditioner is too dirty, and the air outlet is blocked, resulting in difficulty in dissipating heat.

If your air conditioner is more than within this range, then you have to ask a maintenance master to come to service, and generally adding a snow is enough to make it last for several years.

But keep in mind that sometimes even if you add refrigerant, the cooling effect is not necessarily good, maybe the air conditioner is too long, and all aspects of the function should indeed be replaced.

There may be a variety of reasons for this, one may be the reduction of refrigerant, resulting in a decrease in heat exchange efficiency, the other may be that the heat dissipation effect is not good due to dust accumulation in the external heat sink, or it may be that the network insulation layer is damaged or the efficiency of the compressor is reduced, etc., you can find a special maintenance personnel to help you check it.

The air conditioner not cooling may be due to insufficient refrigerant, and the appropriate amount of refrigerant should be added.

When the refrigerant circulating in the refrigeration system is insufficient, the pressure values on both the high and low pressure sides will be lower than normal, and the bubble flow can be seen from the observation window. At this time, after checking that the air conditioner does not refrigerate the system without leakage, an appropriate amount of refrigerant should be added.

If the refrigeration dose charged exceeds the normal capacity of the refrigeration system, the liquid refrigerant in the condenser will inevitably increase, thereby reducing the heat dissipation area and reducing the cooling efficiency.

Precautions for the use of air conditioners

When using air conditioning, the temperature of the air conditioner should not be adjusted too low in summer, and the temperature of the air conditioner should not be adjusted too high in winter, because the temperature of the air conditioner can be lowered by one degree, which can reduce the electric load of 7 and 10, and the use of air conditioning will also be more energy-saving, and at the same time, for the sake of health, the indoor temperature and the outdoor temperature difference of 4 to 5 degrees Celsius in summer will be on the line, and when the temperature difference is too large, it is easy to cause a cold.

Before using the air conditioner, ventilate the room in advance, so that when using the air conditioner, you don't need to open the doors and windows from time to time, which can effectively keep the indoor temperature from being lost, and the effect of air conditioning and heating will be better.

Cause: Long-term fouling or reduced refrigeration effect. Workaround:

If it is a problem of dust accumulation, it is necessary to pay attention to cleaning up the dust frequently during the use of the air conditioner to ensure the normal operation of the air conditioner. If the refrigerant doesn't work well, add freon to the line. If it is not for these two reasons, you need to contact the maintenance master for on-site maintenance.

Check whether the high and low pressure of the refrigerant in the main air conditioning and refrigeration system is normal; Check whether there is leakage of refrigerant in the main air conditioning and refrigeration system, and whether the refrigerant needs to be replenished; Check whether the operating current of the compressor is normal; Check whether the compressor running sound is normal, check whether the compressor oil level and color are normal, and check whether the compressor oil pressure and oil temperature are normal; Check whether the phase sequence maintainer of the main air conditioner is normal; Check whether the terminal of the air conditioner is loose; Check whether the water flow maintenance switch is operating normally; Check whether the resistance value of the computer version and the temperature probe is normal.

1. Air conditioner lacks fluorine, fluorine is the most important part of air conditioning to refrigerate, if there is no fluorine or not enough fluorine, it will lead to air conditioning not refrigeration. 2. Not using it for a long time means that there is no cleaning and maintenance for a long time, which will lead to a lot of dust or dirt adhering to the air conditioning filter or other parts, resulting in poor heat dissipation effect and poor refrigeration effect or even no refrigeration when the air conditioner is used. How to deal with it:

1. Under normal circumstances, the air conditioner needs to be fluoride after 5 years of use, if the air conditioner is at this time stage, it should be a lack of fluorine, and it is necessary to contact the after-sales service to add fluoride. 2. The air conditioner also needs to be cleaned regularly, not only the filter of the indoor unit, but also the outdoor unit, so that the air circulation can be smoother and the refrigeration effect will be better when the air conditioner is running. 3. Test whether the voltage is normal, if it is not normal, you can install a voltage stabilizer.

4. Move the outdoor unit of the air conditioner to a more spacious place where it is easier to dissipate heat.

If the air conditioner has not been used for a long time, you can try the following methods:

1.Clean the filter: Cleaning the filter can help the air conditioner circulate air better and improve the cooling effect.

2.Check the refrigerant: If the refrigerant is insufficient, the air conditioner will not be able to refrigerate. You can ask a professional technician to check whether the refrigerant is sufficient.

3.Check the power supply: If the power supply is insufficient or the wires are in poor contact, the air conditioner will not work properly. You can check whether the backup finger of the power supply is normal.

4.Check the outdoor unit: If the outdoor unit is dusty or blocked, it will also affect the cooling effect of the air conditioner. It is possible to clean the room, imitate the limb, and remove the obstruction.

If none of the above methods can solve the problem, it is recommended to contact a professional air conditioner maintenance personnel for inspection and repair.

There are various reasons for not refrigerating, usually in the following situations: 1. Because the freon of the air conditioner is not enough, it is necessary to buy and replenish it in time; 2. When the voltage of the power supply does not meet the requirements or is unstable, it will also affect the air conditioning and refrigeration; 3. If the square of the room is large, and the power of the air conditioner is not enough to meet the needs of the space, then the conditions of the use environment can be used to solve the problem; 4. If the external environment temperature is too high, the use environment of the outdoor unit can be changed to reduce the temperature; 5. If the air conditioner is not cleaned for a long time, a large amount of ash will be piled up and the dust will be patted, and it can be cleaned in time.
