Hello! Inquiries about air conditioner squeaks?

There will be no rainwater backfilling. The noise problem requires a water bend to be made.

The condensate drainage pipe of the indoor unit of the split household air conditioner leading to the outside is discharged by the gravity of the condensate itself, so the indoor unit must be higher than the height of the drainage pipe connected to the rainwater pipe, and it is much higher, so there will be no problem of rainwater backflow in the rainwater pipe.

Make a U-shaped bend before the drain pipe enters the storm water pipe, and store a certain amount of water in the bend, which can greatly avoid the problem of rainwater flow noise spreading along the drain pipe.

If the air conditioner is abnormal, try to find the manufacturer for maintenance. to be solved.

Hello, the dripping sound may be caused by the high water level in the water tray of the air conditioner, and the water dripping when the evaporator fins continue to condense. It may be that the outlet of the water tray is blocked, and if the height of the downpipe inserted into the air conditioner water pipe is lower than that of the air conditioner outlet, it will not be backfilled.

It is normal for the air conditioner to have a dripping sound in the air conditioner on a rainy day, because the humidity is too high on a rainy day, and the humidity is too high, later. Condensation will condense on the fins of the internal urgency, and water will drip after condensation, so you should stop the machine and turn it on again after a while.

Hello for inquiries about the squeak and reverberation of the air conditioner, as he makes a noise between hot and cold.

There is an abnormal sound in the air conditioner when the air is turned on and off.

Fault phenomenon: There is an abnormal sound when the air conditioner is switched on/off.

Diagnosis process: Because it is the abnormal sound that occurs when the air conditioner is turned on and off, it is necessary to check the air conditioning system first, and determine what the sound is according to the abnormal sound, because there are three main reasons for the abnormal noise of the air conditioner: First, the pressure of the high-pressure pipe of the air conditioning system is too high.

Second, the condenser is too dirty and the heat dissipation is not good. 3. The expansion valve is blocked, and the pipeline generates high pressure. The above three reasons are that the pressure at the expansion valve is too high when the air conditioner is turned off, the refrigerant flow rate is too slow, and the compressor does not work after the air conditioner is turned off, and the refrigerant in the pipeline is blocked at the expansion valve, which produces a humming sound under the action of high pressure.

Analysis 1: The pressure of the high-pressure pipe in the air-conditioning system is too high. First of all, connect the CA375 refrigerant filling machine, start the engine, turn on the air conditioner to check whether the pressure of the high-pressure gauge is normal, if it exceeds the specified pressure, it proves that the refrigerant is overfilled, and the refrigerant R134A must be re-vacuumed after the refueling, and the specified filling amount is 600 grams.

Analysis 2: The condenser is too dirty and the heat dissipation is not good. When the radiator is too dirty, it can not dissipate heat for the refrigerant circulating to the condenser, and the overheating in the pipeline produces high-pressure and high-temperature gas, which naturally becomes foam-like gas after mixing with the refrigerant.

The cleaning of the water tank and condenser, if the cleaning is not clean, it will affect the refrigeration effect.

Analysis 3: There is a slight blockage at the expansion valve. When the air conditioner is turned on for a period of time, when the pressure of the high-pressure pipeline rises to the specified value, the high-speed gear of the electronic fan starts to work, and as the pressure in the pipeline rises, if the expansion valve is slightly blocked, the refrigerant flowing to the expansion valve will also produce high pressure, and it will make a buzzing sound when the air conditioner is turned off.

Replace the expansion valve, if the expansion valve is seriously blocked, there will be severe frosting on the low-pressure pipe.

Fault phenomenon: when the air conditioner is turned on, there are two main reasons for the abnormal noise, which can be divided into two situations according to the abnormal sound: one is the metal friction sound emitted when the compressor electromagnetic clutch is engaged, and the other is the squeak sound of the air conditioning belt when the force is too large, both of which will appear when the air conditioner is turned on and refueled.

Diagnosis process: analysis 1: the compressor electromagnetic clutch emits a metal friction sound when it is engaged, and the fault is generally the lack of refrigeration oil for lubrication inside the compressor, when the refrigeration oil is lacking, the piston inside the compressor is not fully lubricated, and the metal friction sound is emitted under the high pressure of the refrigerant. There is also a situation where the electromagnetic clutch itself is faulty, and the internal bearing is damaged and makes an abnormal noise, in which case the compressor can only be replaced.

If there is a lack of refrigerant, you need to first vacuum the refrigerant in the air conditioning system, add enough refrigerant oil, and then add refrigerant, and turn on the air conditioner for a while to fully circulate the refrigerant oil in the pipeline. If the friction is severe, the compressor needs to be replaced.

Analysis 2: The abnormal sound of the air conditioning belt when the air conditioner is turned on, this situation is that the pressure of the air conditioning system rises rapidly when the air conditioner is turned on.

There are two types of abnormal noise of air conditioning, external abnormal noise and internal abnormal noise.

1.The latter is due to the presence of air or moisture in the refrigerant of the system, which produces abnormal noise when the refrigerant evaporates and expands.

2.The former is what you call a phenomenon, and this kind of abnormal noise is generally because the refrigerant components contain air and moisture, but if you add 3If there is still abnormal noise after refrigerant, it is most likely due to damage to the internal mechanical structure of the compressor.

4.If it is after a period of time** and the location is inside the center console, there is a high possibility that the efficiency of the dryer will be reduced.

Hello! 1. The installation is not professional enough, the position is not level, or there is something stuck inside.

2. If an object is pressed on or inside the machine, it will resonate when it starts.

3. The walls of the room are hollow bricks, and the sound of the external machine starting is normal, but it can be transmitted to the room, so it naturally feels loud. (If it is the noise of the internal machine).

1. Each customer's feeling of the sound is different, the normal sound of the internal machine is of course the sound of the air supply, it must be smaller than the fan, of course, there is the sound of the air supply, and the fan is divided into three wind speeds, you can choose according to your preferences.

2. The installation position is not level, which may also cause noise problems, please find the seller.

Personally, I don't think there will be any sound from the internal machine.

Our compressors have this sound, a sound like a wail, especially at about 1000 rpm, the higher the speed is much more comfortable, and it becomes a turbine-like sound.
