What is the frost on the high pressure pipe of the air conditioner

1.It may be that the filter of the air conditioner is too dirty, or the evaporator inside is too dirty, causing clogging and poor ventilation. 2.The fan speed of the indoor unit is too slow, and the temperature exchange is not smooth, which makes the high-pressure pipe frosty. 3.The air conditioner pipe is broken and leaking, which is caused by a lack of freon.

The causes of frosting in the high-pressure pipes of automobile air conditioners are as follows:

1. Blockage: The filter screen is too dirty or the evaporator inside is too dirty, causing blockage, resulting in obstruction of ventilation. 2. Indoor:

The fan speed of the indoor unit is too slow, resulting in poor temperature exchange. 3. Failure: The air-conditioning pipeline is damaged and leaked, resulting in the lack of freon.

The solution is as follows: 1. Check whether the connecting pipe is tightened. If there is an extended pipe during the installation process, the weld should be checked for trachoma.

If the length of the connecting pipe is reduced during the installation process, it is important to check whether the bell mouth of the self-expansion is qualified. 2. Caused by the blockage of the capillary tube of the machine: frost also appears in the capillary tube in the machine, and the current rises all the way from the beginning of the machine until the compressor overheats and stops.

Replacing the capillary tube after the refrigerant is discharged can be solved.

The freezing of the high-pressure pipe is generally caused by the lack of fluorine in the system, the blockage of the filter, the poor temperature exchange caused by the temperature exchanger being too dirty or the fan speed being too slow, and the dirty and clogged capillary of the air conditioner.

Causes and solutions:

1. Add fluoride to the air conditioner in time.

2. Clean the air conditioner or repair and replace the fan motor regularly.

3. Clean up impurities and dredge capillaries in time.

It's normal The compressor takes a lot of heat out when it is working, and then compresses the cold air and sends it to the room, there is a heat exchange process here, so frosting is normal!

If the refrigerant is leaking, it is necessary to check the leakage point and deal with it, and then add refrigerant to the pressure measurement.

The compressor takes a lot of heat out when it is working, and then compresses the cold air and sends it to the room, there is a heat exchange process here, so frosting is normal.

The reason could be refrigerants.

Lacking, refrigerants need to be added; It is also possible that the filter has not been cleaned for a long time, resulting in the inability to ventilate normally; It could also be an expansion valve.

The degree of opening is too small, the condenser.

The temperature of the reflux liquid is too high, then the throttle valve.

Frost will slowly form. The degree to which the expansion valve is opened can be adjusted. 1. The biggest possibility of frosting of high-pressure pipes of air conditioning is because of insufficient refrigerant, and there are many reasons for insufficient refrigerant, it may be that there are quality problems in the machine itself, which leads to refrigerant leakage, after the refrigerant leaks to a certain extent, the air conditioner lacks a large amount of refrigerant, and it will not work normally.

2. The frosting of the high-pressure pipe may also be due to the blockage of the capillary bridge rock pipe of the machine, which can be changed by human annihilation. Therefore, we should regularly unclog the capillary to prevent the capillary from clogging. 3. Evaporator of air conditioner.

If the filter is not cleaned for a long time, a large amount of dust will accumulate, which will lead to low efficiency of alternating cold and heat, and it will be brushed after the sensitive change, so we must regularly clean the evaporator filter of the air conditioner to ensure that the air can be normally alternated between cold and hot under the condition of normal air circulation. 4. From the air conditioning panel.

You can check whether the fan can rotate normally, if the fan does not rotate normally, it will also cause frost on the high-pressure pipe, so when the fan does not rotate normally, it is necessary to repair or replace.

Summary. 1. The filter screen is too dirty or the evaporator inside is too dirty, causing blockage, resulting in obstruction of ventilation.

2. The fan speed of the indoor unit is too slow, resulting in poor temperature exchange.

3. The air-conditioning pipeline is damaged and leaked, resulting in the lack of freon.

So what is the high-pressure pipe and low-pressure pipe, the general situation is: in the process of refrigeration, the small pipe is a high-pressure pipe, and the large pipe is a low-pressure pipe. In the process of heating, the small tube is a low-pressure tube and the large tube is a high-pressure tube, which is the opposite of the above.

To put it simply: the refrigeration tube is at high pressure, the large tube is at low pressure, and the heating is the opposite.

What is the frost on the high-pressure pipe of the air conditioner

1. The filter screen is too dirty or the evaporator inside is too dirty, causing blockage, and the ventilation is blocked. 2. The fan speed of the indoor unit is too slow, resulting in poor temperature exchange. 3. The air-conditioning pipeline is damaged and leaked, resulting in the lack of freon.

What is the high-pressure pipe and low-pressure pipe, the general situation is: in the process of refrigeration, the small pipe is a high-pressure pipe, and the large pipe is a low-pressure pipe. In the process of heating, the small tube is a low-pressure tube and the large tube is a high-pressure tube, which is the opposite of the above.

To put it simply: the refrigeration tube is at high pressure, the large tube is at low pressure, and the heating is the opposite.

The compressor starts frequently, presses the drying bottle up to the switch to short circuit, the compressor works normally, the high pressure freezes in front of the evaporation tank, and the air conditioner does not refrigerate.

Hello, dear, you can take a look at what I sent earlier.
