What s going on with the freezing of the radiator of the air conditioner

1.Insufficient refrigerant. Split air conditioners can leak or leak refrigerants due to long installation or use time. After the refrigerant is reduced in the refrigeration system, the evaporation pressure is too low, resulting in the evaporator freezing, and the icing position is generally at the front of the evaporator;

2.Due to long-term use of the compressor due to failure, the compression efficiency of the compressor is reduced, or the compressor gas distribution system is damaged, resulting in low pressure and freezing;

3.After the evaporator dirty air conditioner is used for a period of time, the dust in the air or the microorganisms produced by the evaporator will accumulate on the evaporator, obstructing air circulation, resulting in reduced heat exchange, and the evaporator temperature is too low to freeze, and the icing position is at the rear of the evaporator;

4.There is too much refrigerant, and some air conditioners are re-injected with refrigerant due to replacement, leakage, etc. The maintenance personnel did not operate properly, and more refrigerant was added, causing too much refrigerant to flow to the evaporator, and then partially evaporated and frozen.

This ice accumulates at the rear of the evaporator and around the compressor return pipe;

The reason for the freezing of the air conditioner.

1. Insufficient refrigerant.

Split system air conditioning for domestic use.

Refrigerant leakage may occur after a period of use, and the reduction of refrigerant will cause the evaporation pressure to be too low, which will affect the refrigeration effect, and eventually lead to the freezing of the outer.

2. Too much refrigerant.

Insufficient refrigerant will cause the air conditioner to freeze, but if there is too much refrigerant, it will also cause the air conditioner to freeze.

3. There is too much dirt in the evaporator.

When the air conditioner is used, because it does not pay attention to regular cleaning, the dust and mud in the air will accumulate on the evaporator, which will lead to the blockage of air circulation, the heat exchange capacity will be weakened, and the temperature of the evaporator will be too low, which will eventually lead to the occurrence of ice freezing of the air conditioner.

4. The thermostat fails.

The function of the thermostat is mainly to control the temperature of the air conditioner, if it is used for too long, the thermostat may fail, in this case, it will also cause the air conditioner to freeze.

Congratulations, you got it right, it's fluorine that's leaking out quickly.

First of all, the maintenance worker you found only added fluoride and did not solve the problem of fluorine leakage, which is too irresponsible, because there is a leakage, and there is less fluorine in a few days, which causes the indoor unit (heat dissipation outlet) to freeze, and the temperature of the air outlet will not reach 14 degrees, so the refrigeration is not enough. Leaks should be detected first, generally (4) interface problems, and then fluorine is added after solving the problem.

In addition, if the outdoor unit of the air conditioner is dusty (the air conditioner is blocked), it can be refrigerated normally, but it will stop after a short working time, and it will work again after a period of time. It is necessary to clean the outdoor unit once after the air conditioner has been used for more than 5 years.

Under the condition of heating, the outdoor unit is in a refrigeration state, and the water vapor in the air will frost when it encounters a relatively cold heat sink, and it will freeze when the humidity is high, which will affect the normal operation of the air conditioner, so the air conditioner will defrost at intervals during heating.

In winter, if the air conditioner is used for heating, the external heat sink will freeze, and it can only be defrosted by automatic control, and there is no other good way, and the effect of internal heating will be significantly reduced after freezing. If you want to melt ice quickly, turn on the electric heating function of the air conditioner (this function is not available in all air conditioners).

How to deal with the freezing of the air conditioner? What causes it?

It doesn't matter if the air conditioner is turned on, the heat sink will thaw there, and the air conditioner will blow hot air after it is turned on.

If the evaporator of the air conditioner freezes, you can increase the setting temperature of the air conditioner to solve the problem.

The grass and trees are all soldiers, and they are in a dilemma.

If the air conditioner is too dirty, the fan speed is too slow, and the system lacks fluorine, there may be icing in the internal machine.

It is recommended to contact after-sales service or ask a professional for maintenance.

After more than 10 years of experience, I have summarized that there are several main reasons for the freezing of air conditioners

1.Not enough refrigerant in an air conditioner can lead to freezing.

2.The internal fan capacitor causes low rotational speed and ice formation.

3.The inner fan fins are too dirty, resulting in insufficient heat absorption and freezing.

4.Dirty filters can also lead to icing.

It should be caused by poor condensate drainage and blockage, and I am really helping you look forward to it

Summary. Hello! Analysis of the causes of the freezing of the radiator of the air conditioner, the cause of the freezing of the radiator of the air conditioner 1, the lack of refrigerant, the phenomenon of refrigerant leakage may occur after a period of use, and the reduction of the refrigerant will lead to too low evaporation pressure and affect the refrigeration effect, and eventually lead to the freezing of the external mixer.

2. Too much refrigerant, not enough refrigerant will cause the air conditioner to freeze, but if there is too much refrigerant, it will also cause the air conditioner to freeze.

Hello! Analysis of the causes of the icing of the radiator of the air conditioner, the original cause of the icing of the radiator of the air conditioner: 1. The refrigerant is insufficient, and the phenomenon of refrigerant leakage may occur after the split air conditioner is used for a period of time, and the reduction of the refrigerant will lead to too low evaporation pressure and affect the refrigeration effect, and eventually lead to the freezing of the external machine. 2. Too much refrigerant, not enough refrigerant will cause the air conditioner to freeze, but if there is too much refrigerant, it will also cause the air conditioner to freeze.

3. When the evaporator is used with too much dirt, the air conditioner will accumulate on the evaporator because it does not pay attention to regular cleaning, and the dust and mud in the air will accumulate on the evaporator, which will lead to the blockage of air circulation, the heat exchange capacity will be weakened, and the temperature of the evaporator will be too low, which will eventually lead to the occurrence of icing of the air conditioner. 4. Thermostat failureThe function of the thermostat is mainly to control the temperature balance of the air conditioner, if it is used for too long, the thermostat may fail, in this case, it will also cause the air conditioner to freeze.

Hello! The above is the analysis of the causes of the freezing of the radiator of the external unit of the air conditioner.

The icing of the heat sink of the air conditioner may be caused by the following reasons:

1.The filter screen of the air conditioner is blocked, resulting in poor air flow and the heat sink cannot effectively dissipate heat, resulting in icing.

2.The air conditioner has insufficient refrigerant or the refrigeration system is faulty, resulting in poor refrigeration, which leads to icing.

3.The temperature of the air conditioner is too low, causing moisture in the air to condense on the heat sink, resulting in the formation of ice.

In view of the above problems, the following measures can be taken:

1.Clean the air conditioner's inner filter regularly to ensure smooth air flow.

2.Regularly check whether the refrigerant in the air conditioner is sufficient, and repair the refrigeration system failure in time.

3.Adjust the temperature of the air conditioner to avoid freezing caused by too low a temperature.

If the above measures cannot solve the problem, it is recommended that Huaibi contact professional air conditioning maintenance personnel for maintenance and maintenance.
