What is the reason for the freezing of the radiator of the indoor unit 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;

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

1. Lack of freon in air conditioning.

Insufficient or too much refrigerant in the air conditioner: In the case of an air conditioner, if the refrigerant is insufficient, the pressure of the evaporator may be too low and thus freeze, so it is only necessary to add enough refrigerant to it.

If there is too much refrigerant inside the air conditioner, it may also cause the air conditioner to freeze. Because too much refrigerant may flow to the evaporator of the air conditioner and cause it to freeze, the solution: ask a professional to drain the fluoride of the air conditioner.

2. Problems with the throttle valve.

If the cooling capacity and temperature settings of the air conditioner are normal, but the temperature of the air outlet cannot be detected, it is likely that there is a problem with the throttle valve.

3. The evaporator of the air conditioner is dirty.

The icing of the air inlet of the inner machine is the icing phenomenon of the evaporator. The evaporator will freeze, because the airflow will become smaller due to too much refrigerant or dirty dust accumulation on the filter screen, and the amount of air heat exchange will become smaller, and the refrigerant will not be completely vaporized, resulting in liquid compression, resulting in the freezing of the compressor return pipe. Drain some refrigerant and clean the filter or evaporator fins.

4. Air conditioning compressor failure.

If the compressor is used for too long, there is a possibility that the compressor will be damaged or the power will be reduced, which will cause the inside of the air conditioner to freeze.

Solution: Add refrigerant to the compressor to see if it can be solved, if it is not handled well, it can only be replaced.

If your air conditioner is throttled outdoors, then one of the two outdoor pipes will also freeze. It is very simple to find the leakage point, ** where there is oil leakage, there will basically be fluorine leakage, if the connecting pipe is leaking, you can peel off the insulation layer, use soapy water (laundry detergent water, Jiejieling and other foam) brush it, and the bubbling place is the leakage point.

The upper part of the indoor unit is frozen, is it refrigerant overcharged?

There is basically no F22, there must be a leak somewhere, is it moved to the machine?

Is the air volume normal? Could it be that the back of the evaporator is blocked by dust and impermeable?

What you said is too confusing, is it frost on the outdoor unit or frost on the outdoor unit, and if it is frost on the indoor unit, how can it not be cold at all?

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.

Hehe, in winter, if the air conditioner is used to heat, the heat sink of the external unit will freeze, and it can only be defrosted by automatic control, 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).

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

Summary. Dear Hello The reason why the radiator of the indoor unit of the Gree air conditioner is frozen.

Causes of icing of the indoor unit of the air conditioner.

1. The filter screen is dirty and blocked, resulting in a decrease in air flow rate and icing failure of the indoor unit; Clean the air conditioner filter regularly.

2. After the air conditioner lacks fluorine, it will cause serious icing or frosting of the indoor unit of Gree air conditioner; Beijing Gree air conditioner fluoride should be fluoridated in time.

3. The automatic defrost function fails; Ask a technician to check for exclusions.

4. The blockage of the air conditioning flow will also lead to the freezing of the indoor unit of the air conditioner.

The radiator of the indoor unit of the Gree air conditioner is frozen.

Dear, I'll give you this question, it takes a little time to type, please be patient.

The reason for the freezing of the radiator of the indoor unit of the Gree air conditioner is the reason for the freezing of the indoor unit of the air conditioner1, the filter screen is dirty and blocked, which leads to the decrease of air flow rate and causes the icing failure of the indoor unit; Clean the air conditioner filter regularly. 2. After the air conditioner lacks fluorine, it will cause serious icing or frosting of the indoor unit of Gree air conditioner; Beijing Gree air conditioner fluoride should be fluoridated in time. 3. The automatic defrost function fails; Ask a technician to check for exclusions.

4. The blockage of the air conditioning flow will also cause the air conditioner to freeze the indoor unit.

Solution: There is condensate out to indicate that the air humidity is very large, close the doors and windows of the room tightly, run for a period of time, the air humidity in the room is reduced to pure, and the condensate will be less, but the note is that the chain is the basis of the room is called to be sealed tightly, and there can be no place for ventilation and gas.

I hope the above is helpful to you If you are satisfied with me, please give a thumbs up and I wish you a happy life.

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.
