What should I do if the air conditioner does not refrigerate after adding refrigeration

Shenzhen Mitsubishi air conditioning maintenance.

Re: After the air conditioner is moved, refrigerant is added, but it is still not refrigerated, and it is generally not a matter of pipes. At that time, you added fluoride after moving the machine, did it refrigerate?

If you don't refrigerate, where is the fluoride added? If you add fluoride after moving the machine, there was refrigeration at that time, but there is no refrigeration until now, which means that your air conditioner is still leaking fluoride and causing no refrigeration. You don't have to worry about the texture of the tube used in the air conditioner, if you add fluoride after moving the machine, it is refrigerated at that time, and the most important thing is to check the leak.

Regarding the fact that your air conditioner is not refrigerated after moving, you also need to see if your air conditioning pipe is deflated, if it is deflated, it is related, Freon plus more air conditioner is also not refrigerated, and there is no air exhaust will also have an impact.

According to the normal steps of air conditioner relocation: first unscrew the two large screw caps on the two tubes, and then tighten the screws in the thin tube clockwise with the hexagon when collecting fluoride, and then tighten the screws in the thin pipe clockwise, work for about half a minute, and quickly turn off the power supply after tightening the screws in the thick pipe.

It started to run normally for a while and then stopped.

Generally, there is a leak in the refrigeration system pipeline.

Check out the leakage, in general, there must be a refrigerant leak in this case.

If you feel that there is a big gap between the temperature difference and the value you set, then it is definitely a problem with the circuit.

You can take a look for yourself, there are two connecting pipes, one thick and one thin, one of which is not cold or frosty, then it must be insufficient refrigerant.

If you have a problem with your air conditioner, please call the following ** in your city for repair, or you can call directly.

If you add more refrigerant, you will not be afraid to clean it, just this sentence can prove that the master you ask will not repair the air conditioner at all, and adding refrigerant and cleaning are two different things.

Adding more refrigerant will increase the workload of the compressor, resulting in automatic protection (no refrigeration) phenomenon, you must now ask the master to reduce the refrigerant again, so that your air conditioner can work normally.

Refrigerant is added. There are two situations for the original shouting filial piety of the air conditioner, one is due to the maintenance personnel replacing the refrigerant that does not match the air conditioner, and the other is due to the maintenance personnel adding more refrigerant or seeping air in the case of using the correct refrigerant, and it may also be caused by no leak detection.

There are certain techniques for refrigerating the air conditioner, and the specific methods are as follows:

1. Turn on the air conditioner in refrigeration mode to make the external unit work normally.

2. Open the small nut of the Dalian takeover triangle valve of the external unit.

3. Connect it with a professional refrigerant connecting pipe.

4. The starting pressure of the refrigerant can be added between them.

Precautions for air conditioning and refrigeration:

1. When adding, first add from the high-pressure pipeline, and then add from the low-pressure pipeline, the compressor cannot run when adding from the high-pressure pipeline, and the air-conditioning system when adding from the low-pressure pipeline.

Must be at maximum load.

2. When looking at the meter, you can see which pressure gauge to add from which pipeline.

Low pressure is generally above MPa, and high pressure is generally above MPa.

3. When adding, two to three cans are generally added, and the capacity of each can is 300 grams.

4. You can't add more or less, depending on the specific model instruction manual, the pressure will be greater if you add more, and the refrigeration effect will not be good if you add less.

Summary. There could be a variety of reasons why the air conditioner doesn't refrigerate after a few days, and here are some of the possible reasons:1

Check if the air conditioner's filter is clogged. If the filter is clogged and the air circulation is not smooth, it may cause the air conditioner to not cool or not refrigerate well. 2.

Check that the condenser of the air conditioner is clean. If the condenser is covered with dust and dirt, it may affect the heat dissipation of the air conditioner, resulting in the air conditioner not cooling or not cooling well. 3.

Check the aircon for leaks. If the refrigerant of the aircon leaks, it may cause the aircon to not cool or not refrigerate well. This situation requires inspection and repair by a professional technician.

4.Check if the compressor of the air conditioner is working properly. If the compressor of the aircon is damaged or malfunctioning, it may cause the aircon to not cool or not refrigerate well.

5.Check that the electronic controller of the air conditioner is working properly. If the electronic controller of the air conditioner is faulty or damaged, it may cause the air conditioner to not cool or not cool well.

If your aircon is not cooling or does not cool well, it is recommended that you first check that the filter and condenser are clean, and clean them. If the problem persists, it is recommended that you contact a professional technician for inspection and repair.

If the problem persists, it is recommended that you contact a professional technician for inspection and repair.

1. If the air conditioner is evacuated and the snow bend is planted carefully, it is necessary to repair the fault, such as ice blockage. Wrong refrigerant for other models. It should be reminded that after the air-conditioning system is emptyed, if the refrigerant is added, the air in the pipe must be evacuated or emptied.

Second, the refrigerant is also the refrigerant, it is in a closed environment for refrigeration cycle, if the refrigeration effect is not good, the refrigerant leakage caused by pipe damage in the air conditioning and refrigeration system should be considered, at this time should be checked and this silver should not be blindly added refrigerant, otherwise it may leak again.

So to sum up the above, the subject does not need to let go of the refrigerant to add the refrigerant. Generally, the air conditioner is refrigerant from the low-pressure pipe, and the air conditioner is turned on first to ensure that the compressor is in operation, and then the pressure gauge is used to add the refrigerant from the low-pressure pipe.

The reasons why the air conditioner can't add refrigerant can be known as follows:

The temperature is too high: If the ambient temperature of the air conditioner is too high, it may cause the working pressure of the air conditioner to be too high and unable to absorb the refrigerant into the refrigeration system.

Insufficient refrigerant: If there is not enough refrigerant, it may cause the air conditioner to not function properly. This usually happens when a new type of refrigerant is filled or when the type of refrigerant is changed, as the new type of refrigerant has not yet fully entered the system.

Clogged pipes: If the pipes are clogged with dirt and impurities, it may cause refrigerants to not enter the air conditioning system.

System leaks: If there is a leak in the air conditioning system, it can lead to a leak of refrigerant, which can deprive the system of enough refrigerant to function.

Network Valve Failure: If the network valve fails, it may prevent refrigerants from entering the air conditioning system.

It should be noted that before refueling, it is important to ensure that the air conditioning system is turned off to prevent refrigerant leakage or damage to the machine. If you are unable to solve the problem by yourself, please contact a professional repairer, Lu Hu, for inspection and repair.

From a scientific point of view, this phenomenon is that if the inside of the air conditioner is already filled with refrigerant, it is not possible to add more refrigerant to it. This is because there is only a limited volume inside the air conditioner, and the volume has reached the upper limit after being filled with refrigerant, and then adding the state refrigerant will cause the pressure to be too high, which will make the air conditioner work abnormally and even damage the air conditioner.

Therefore, in the case of air conditioners, refrigerant filling can only be carried out in the event of a refrigeration problem.

The main reasons are:

Refrigerant leakage: If there is a leak inside the air conditioner, the refrigerant will be lost, resulting in a decrease in cooling effectiveness. In this case, it is necessary to repair the leak as soon as possible and replenish the appropriate amount of refrigerant.

Installation of Sail Biyu quality problems: If the air conditioner is not operated properly or there are quality problems during the installation process, it may cause the refrigerant to be unable to circulate and use normally, and it needs to be reinstalled or repaired at this time.

Mismatch of refrigerant type: Different types of air conditioners require different types and quantities of refrigerants, if you use inappropriate refrigerant or add too much refrigerant, it will affect the cooling effect and power consumption of the air conditioner.

Please click to enter ** to describe the number of reputations.

To be more specific, the air conditioner may not be able to refrigerant due to the fact that it has been filled with enough refrigerant, refrigerant leakage, or installation quality issues. When using air conditioners, it is necessary to pay attention to regular maintenance and maintenance to ensure that they work normally, and at the same time, it is also necessary to avoid environmental pollution and equipment damage caused by indiscriminate addition of refrigerants.

The inability to add refrigerant with empty envy may be caused by one of the following reasons:

Blocked air conditioning lines: Blocked air conditioning lines can cause the refrigerant to not enter the air conditioning compressor through the lines. You can check the aircon lines for blockages or leaks and make sure that all the lines are clear.

Insufficient refrigerant: Insufficient refrigerant can cause the air conditioner to not function properly. You can check if the refrigerant storage tank is sufficient or if the refrigerant needs to be replaced.

Air conditioner failure: An air conditioner failure can cause the refrigerant to not enter the air conditioner compressor. You can check if the circuit of the air conditioner is working properly and if the compressor is running properly.

Unbalanced refrigerant filling: Improper refrigerant filling operations can prevent refrigerant from entering the air conditioning compressor. You can check the refrigerant filling manual to make sure the filling process is up to specification.

If you are unable to determine the specific cause of the problem, it is recommended that you contact the after-sales service personnel or professional maintenance personnel for maintenance.

If the air conditioner is unable to incorporate refrigerant, there may be several reasons:

Defective refrigerant bottles or pipes: Inspect the refrigerant bottles or pipes for damage or blockages. If the refrigerant bottle is cracked or the pipes are clogged, it will not be possible to inject the refrigerant into the air conditioning system.

Not enough refrigerant: Make sure there is enough refrigerant in the refrigerant bottle. If there is not enough refrigerant, it may not be possible to inject enough refrigerant into the air-conditioned celery system.

Error: Make sure you're following the correct steps. Different brands and models of air conditioners may have different refrigerant injection methods and procedures, please read the user manual of the air conditioner carefully or refer to the operation guide provided by the manufacturer.

System Failure: If you have followed the correct operating steps but are still unable to add refrigerant to the air conditioning system, there may be a fault with the air conditioning system itself. In the case of this cavity replanting, it is recommended to contact the air conditioner manufacturer's technical support team or professional air conditioner maintenance personnel for further diagnosis and repair.

The refrigerant of the air conditioner cannot be added, and it is very likely that the reason is that there is no vacuum inside the air conditioner, which leads to the pressure of the old Bi part of the body, and it is impossible to add the refrigerant normally. Or the expansion valve of the air conditioner is blocked, resulting in the refrigerant being unable to be added from the valve.

Air conditioner refrigeration may occur when there is a leak in pipes, connectors, valves, or other parts of the indoor and outdoor units.

Most of the time, when people refrigerate the air conditioner, the air conditioner will recool down. But why do some people's air conditioners still not cool after adding refrigerant? How to solve the problem that the air conditioner and refrigerant are not cold?

The reason why the air conditioner and refrigerant are not refrigerated: the refrigerant does not match or the amount is wrong

Air conditioningThe refrigerant is not refrigerated, it may be that the refrigerant added by people does not match the air conditioner, or the refrigerant is added more, or the refrigerant is added less. At this time, it may be because the fluorine we add does not match the air conditioner, or it may be because the amount of fluoride added is wrong, such as adding more or less fluorine. Therefore, in the case that the air conditioner is not refrigerated by fluoride, we need to rule out that the air conditioner is not refrigerated because of incorrect fluoride.

The solution is to change the appropriate refrigerant, if the refrigerant is less, add some refrigerant, and the more should be reduced to the appropriate dose.

The reason why the air conditioner and refrigerant are not refrigerated: the air conditioner filter is too dirty

If your air conditioner is not cooled with refrigerant, you should see if your air conditioner filter is too dirty and has a thick layer of dust on the surface. After the dust on the surface of the filter is passed, the air conditioner will be blocked, so it is not cold. The solution is to clean the air conditioner filter, preferably once a year.

The reason why the air conditioner and refrigerant are not refrigerated: insufficient voltage.

The air conditioner is still not refrigerated, and it may be that the voltage is insufficient. The voltage we are using now is 220V, generally speaking, the voltage is normal, but some situations will lead to insufficient voltage, and eventually lead to the air conditioner not cooling. The solution is to ensure that the voltage is sufficient, and the voltage problem can be found by a professional to see what the cause is.

The reason why the air conditioner does not refrigerate is that the parts of the air conditioner are damaged.

If the compressor, fan and capacitor of the air conditioner are damaged, it will also cause the air conditioner to not refrigerate after adding refrigerant. The solution is to ask the air conditioner maintenance master to come to the door to replace the corresponding accessories.

In addition to the above reasons, improper installation of the air conditioner or poor working environment, and too high temperature of the external unit will also cause the air conditioner to be refrigerated and not refrigerated. Whatever the reason, when people can't find the cause, asking after-sales maintenance personnel to come to the door is the best solution.
