What is the reason that the air conditioner is windy but not cool?

1.Air conditioner leakage or lack of fluorine.

If the reason why the air conditioner is not cooling is because of the lack of fluorine, this situation will generally occur when the air conditioner has been used for three or four years or even longer, which is very normal because it is normal consumption. Even if you are deficient, it will not be completely uncool, and it will not be much worse than usual. At this time, it is good to add enough fluoride.

2.The air conditioner voltage is insufficient.

Sometimes we will encounter some tricky problems, such as the air conditioner is not cool, but it is normal when we check it, but we can't find the problem. Until the final inspection, it turned out to be a voltage problem, especially during peak electricity consumption periods. This phenomenon is even more pronounced.

3.The air conditioning was not powerful enough.

Insufficient power of the air conditioner is also a reason why the air conditioner does not refrigerate, but there are many reasons for this problem. For example, install a low-power air conditioner in a relatively large house. Sometimes the power of the air conditioner and the size of the room seem reasonable, but the house is too poorly sealed or there are some other heat sources, resulting in no cooling, etc.

Maintenance during general air conditioning.

1.Remove debris from the vents to ensure proper ventilation. Observe whether the outdoor rack is loose, and clean the outdoor ventilation grille for foreign objects. At the same time, keep the vents open.

2.Clean the surfaces of indoor and outdoor heat exchangers to improve the efficiency of heat exchangers. When cleaning the indoor heat exchanger, the panel should be carefully removed, scrubbed with a soft rag, and gently scrubbed with a small brush to remove dust and harmful deposits that can multiply germs.

However, because the heat sink is made of thin aluminum, it is easy to deform after being stressed, so it should be brushed carefully.

3.Remove dust from the filter. When cleaning the filter, cut off the power supply first, and then open the air intake grille; Remove the filter and clean it with water or a vacuum cleaner.

The water temperature should not exceed 40 degrees. Wash with a hot, damp cloth or mild detergent, then wipe with a dry cloth. At the same time, the filter should not be cleaned with pesticides or other chemical cleaners.

Then determine which part of the machine is not normal. For example, if the internal and external units are not working, whether the control part is normal, if the machine is operating normally but is not refrigerated, then suspect whether there is a refrigerant problem. Judging from what you said, there is no condensate discharged from the indoor unit, which may not be refrigerated.

The pipeline of the external unit has a low temperature, which means that there is still a refrigerant. If the power cord is not unplugged for a long time, it may damage the control circuit of the machine. 1. The air conditioning mode is set on ventilation.

2. The starting capacitor of the external compressor is broken. 3. The air-conditioning and refrigeration system lacks refrigerant (freon). 4. The tube temperature sensor of the evaporator of the internal machine is broken.

According to the above relevant information about how the air conditioner is not refrigerated, it is not possible to immediately determine the cause of the failure, or report to the maintenance department of the repair manufacturer for on-site inspection.

The reason may be: the first air conditioner has just been turned on for a short time, and it has not yet begun to enter the refrigeration state, because the air conditioner has a delay protection effect when it is just turned on, and it can be refrigerated after a few minutes. The second possibility is that the refrigerant of the air conditioner is leaking and lacking refrigerant, so it is necessary to find professional maintenance personnel for maintenance.

Running normally but not cold, there are several directions to think about:

1. The number of air conditioners is too small, and the room is too large;

2. There are too many people in the room or there are other household appliances such as heating;

3. The room is airtight and poorly insulated, and the heat outside the room intrudes too much;

4. The air conditioner itself is due to factors such as leakage media, poor heat dissipation of the condenser, etc.; insufficient refrigeration capacity;

5. The set temperature is too high.

The air conditioner cools but does not have a cool breeze that can be due to the following reasons:

Fan failure: The fan inside the air conditioner may malfunction, causing the air to circulate and prevent cool breezes.

Blocked airflow: The airflow channels inside the air conditioner may be blocked, such as filters, evaporators, etc., resulting in air that cannot circulate and thus prevent cool breezes.

Insufficient refrigerant: Insufficient refrigerant in air conditioning may lead to poor refrigeration effect, resulting in no cool breeze.

Internal icing: The inside of the air conditioner may freeze due to long-term use or other reasons, which will affect the cooling effect and not produce cool breezes.

Controller failure: The air conditioner controller may malfunction, resulting in the air conditioner not working properly and no cool breeze.

To solve the above problems, you can try the following solutions:

Check if the fan inside the air conditioner is working properly and if it fails and needs to be replaced.

Clean the filter, evaporator, etc. inside the air conditioner to ensure that the airflow channel is unobstructed.

Check whether the refrigerant of the air conditioner is sufficient, and if it is insufficient, the refrigerant needs to be added.

Turn off the air conditioner and wait for the internal ice to melt before restarting.

Check whether the air conditioner controller is working properly, and if it is faulty, it needs to be replaced or repaired.

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

It may be that there is air leakage in the cold circulation system, to check whether the air conditioner can operate normally, including the indoor unit and the outdoor unit, especially to check the compressor of the outdoor unit, if it is impossible to judge the cause of its failure, it is recommended to find a professional maintenance personnel in time to check and repair the air conditioner.

If it works properly, it may be due to serious dust accumulation in parts such as the filter, disassemble the filter and clean it with clean water and a soft brush. Use a special cleaning solvent to clean the surface of the evaporator.

It may also be caused by insufficient refrigerant, if it has not been added for more than 3 years, you need to ask the maintenance personnel to check and replenish it, and check whether there is any air leakage by the way.

If there are no above problems, the air conditioner can also operate normally, then it is necessary to check the operation of the air conditioner fan, if the air volume of the fan is very small, then it may be that the fan motor is old, then it is necessary to replace the new fan motor.

In the process of using the air conditioner, we will have such a feeling, the new air conditioner will be extraordinarily powerful; Whether it is cooling or heating, it is very fast, and the effect is also very good.

If we buy a new air conditioner, in the case of cooling, there is a cold air, but it is not cool enough; I think most of it was the installation process of the air conditioner, and there were abnormalities and failures

In my personal opinion, the main reason for this situation is the following reasons, and we need to find relevant solutions for these reasons.

1. Whether the power of the room and the air conditioner matches when we buy the air conditioner, we must buy it in combination with our own usable area. If you are not sure about the power of the air conditioner, you can measure the area of the room, and then ask the shopping guide to buy the right power air conditioner according to her recommendation.

When the power of the air conditioner is small and the usable area is large; This kind of refrigeration will not work well. This is all because the power of the air conditioner is too small to allow the temperature in the whole room to reach our ideal comfortable temperature.

In addition, you can also look at the corresponding wind power of our air conditioner in refrigeration mode; You can adjust the wind to the maximum and see how well the cooling works.

Second, whether the air conditioning installation is correct or not depends on the compressor and fluorine, and most of the air conditioners used now are inverter air conditioners; In this case, the air conditioner needs to be evacuated during the installation process, and it is also necessary to ensure that no fluorine leakage is carried out. Therefore, the installation of air conditioners is not only a dangerous job, but also a professional technical job.

If the air conditioner is not installed correctly, it will inevitably affect the normal use of the air conditioner; There may be a situation where our common new air conditioner does not refrigerate well.

In view of the above two situations, the first one is more difficult to solve, which is a mistake in the purchase of air conditioners. The second one is relatively easy to solve, it is recommended to contact the after-sales personnel of the air conditioner, let them come to overhaul it, and correct the wrong place.

1. The mesh of the indoor unit is too dirty and not cleaned, resulting in too high pressure in the refrigeration system, so the air conditioner will automatically take protective measures.

2. The power supply voltage is too low, the indoor unit and outdoor compressor are not started, and the machine is not working in the refrigeration state, so the wind is not cool.

3. The room is large and the air conditioner is small, and there is no air conditioner with normal cooling capacity in proportion.

The refrigerant in the refrigeration line of the air conditioner leaks and reduces the cooling capacity. If it is a refrigerant leak, then it is time to have a professional repair and fluoride (refrigerant).

Check the outdoor unit, under normal circumstances, if there is too much dust on the radiator of the outdoor unit, it will also cause the air conditioner to work normally, but the temperature of the air outlet of the indoor unit is high, which reduces the cooling capacity of the air conditioner.

The power supply voltage is low, the outdoor compressor of the air conditioner is not started, and the machine is not working in the refrigeration state, so the wind blowing is not cool.

The room is large and the air conditioner is small, and there is no air conditioner with normal cooling capacity in proportion (such as a room of 30 square meters, you go to install a small machine, that is, 32 hang-up), so the cooling capacity of the refrigeration cannot meet the requirements, so the temperature cannot be lowered.

The indoor unit mesh is too dirty and not cleaned, resulting in too high pressure in the refrigeration system, so the air conditioner will automatically take protective measures.

Maybe the air conditioner you bought is a refurbished machine, and there is less fluorine in it, so you should give the after-sales service a **, let them check it, or add a little fluorine.

That's because there is no fluorine in the air conditioner, which is a necessary condition for air conditioning refrigeration, and fluoride must be added to the air conditioner to cool down.

Generally, it is caused by the external unit not being installed properly. In this case, it will not be cool, so call the master to come to the door to see.

The phenomenon of air conditioning having wind and wax but not irritating and slippery refrigeration is called the poor refrigeration effect of air conditioning by most people, what are the reasons for the poor refrigeration effect of air conditioning? Let's analyze it together:

1. Look at whether the internal machine is dirty and the limb network is dirty. If it is dirty, it is necessary to clean the air conditioner over-concern net;

2. See if the heat dissipation of the external unit is good. If there is a shield around the air conditioner that affects the heat dissipation of the external unit, it needs to be removed immediately;

3. Check whether the evaporator and condenser of the internal unit of the air conditioner are dirty. If it is dirty, the air conditioner needs to be cleaned and maintained;

4. Measure the pressure of the air-conditioning and refrigeration system, and if the return pressure is lower, the air-conditioner needs to be fluoridated;

5. Carefully observe whether there is a deflated phenomenon in the refrigeration pipeline, if so, cut off the deflated place and re-weld;

6. Check whether the refrigeration system has a reversing valve or compressor stringing gas, if so, change the four-way reversing valve or air conditioning compressor;

Summary. Improper installation of air conditioners, long ventilation pipes, and low heat transfer efficiency will also cause non-cooling.

Hello, I have seen your question and am sorting out the answer, please wait for a while There are generally the following reasons for the air conditioner not to refrigerate which blowing blower: whether the set temperature is lower than the actual temperature of the room, if it is lower than the set temperature, the compressor will automatically shut down; Whether the compressor is running normally, if the lead code rotation is not checked, it cannot be refrigerated; Whether there is a lack of refrigerant, if it is missing, it is necessary to add fluoride in time.

There was a cold breeze, but it wasn't so cool in the room.

There is no shortage of refrigerants.

It just needs to be flushed.

Or you take the net down.

Wash it up. Cleaned, the cleaning master checked the Chafo, there is no shortage.

Isn't the number of horses small, but the house is big.

The air conditioner of the big horse, the room, is only ten square meters.

That should be no problem.

Improper installation of air conditioners, long ventilation pipes, and low heat transfer efficiency will also cause non-cooling.

The outside machine, the screw out, there is ice appearing, and the tube in the room is one meter long.

You let the installer take a look.

There may be an installation issue.

1. It may be a lack of fluorine, and if the air conditioner is used for a long time, there will be a lack of fluorine, which will lead to a decrease in the refrigeration capacity of the air conditioner or no refrigeration, which is a common reason. 2. Some families buy the first air conditioner, when the air conditioning ventilation pipe fails, resulting in ventilation problems, it will affect the refrigeration effect of the air conditioner. 3. If the air conditioner cannot work normally, then the refrigeration effect of the air conditioner must be bad.

Suggestions and treatment methods: 1. If the air conditioner is not cleaned and used for a long time, a lot of dust will be adsorbed on the filter, wind blade and wind wheel of the internal unit, resulting in a low temperature of the indoor unit air outlet. As long as it is used and cleaned regularly, the state of uncooled air conditioner can be avoided.

2. The outdoor temperature is too high, resulting in the condenser temperature of the air conditioner exceeding the condensation heat dissipation temperature, and the air conditioner cannot work normally. You can first cool down the outdoor unit, such as showering water and shading, so that the outdoor unit of the air conditioner is in a comfortable working environment. If the air conditioner is turned on at night, the air conditioner can operate normally, and the cooling effect is good, there is no need to report for repair.

3. Check whether the horsepower of the air conditioner matches the size of the room. The size of the air conditioner is determined by the number of horses, and the number of air conditioners has the most direct relationship with the usable area.
