How to solve the problem of dripping copper pipes of air conditioners

1.What causes dripping copper pipes outside an air conditioner?

This is normal. The copper pipe outside the air conditioner drips, which is generally a low-pressure return pipe. There is gas inside that flows back from the evaporator, and it is still evaporating before it is returned to the compressor, but the strength is low.

If the surrounding air is humid, it will condense dripping. The thinner pipes are high-pressure pipes with high-temperature and high-pressure gases inside. Generally, it will generate heat, and the surrounding air will not condense and will not drip.

If it does not drip water, it can be wrapped with insulation so that it does not come into contact with the air.

2. How to protect and repair the dripping copper pipe outside the air conditioner?

1.Pre-startup maintenance.

Usually, household air conditioners are turned off in September, and turned on in May and June of the following year, and stopped for more than half a year. Therefore, it is necessary to do a comprehensive "diagnosis" before starting the air conditioner. Check the air conditioner for "faults".

According to the results of the inventory, under the guidance of professional and technical personnel, do a good job of maintenance and cleaning. This maintenance and cleaning should be in place, including the casing, fuselage, and filter screen of the outdoor unit and indoor unit, and then start the trial operation to observe the cooling speed and effect.

3.Maintenance during start-up.

After the air conditioner is turned on, many factors such as environmental conditions, climatic conditions, starting time, surrounding dust, air cleanliness, and whether the room is clean determine the number of maintenance times of the air conditioner during the start-up process. The environment is poor, the weather is hot, the air conditioner is outdated, the air conditioner starts for a long time, and the number of maintenance increases when the air conditioner starts, generally once a month and a half. If the environmental conditions are good, the air conditioner is relatively new, and there is less dust in the air, turn on the air conditioner reasonably, and the air conditioner and the electric fan are used alternately, and the maintenance cycle can be appropriately extended, from turning on the air conditioner to turning off the air conditioner 1-2 times.

Maintenance should be careful and meticulous, leaving no dead ends. Comply with the specifications, improve the refrigeration speed and effect, and achieve energy saving, freshness and comfort.

3.Maintenance after downtime.

When the weather warms, the air conditioner turns on, and when the weather gets cooler, the air conditioner turns off, which is a perennial rule. Pay attention to perform a thorough and detailed inspection of the outdoor unit and indoor unit before the air conditioner is turned off. Maintenance, maintenance, and cleaning should be done one by one, and they cannot be disjointed.

The missing links should be firmly established and strictly inspected. After the above links are completed, cover the air conditioner to prevent dust pollution, prevent the air conditioner from dripping and leaking, keep it clean, and prepare to use it again next year. This cleans, saves energy, and extends the life of your air conditioning unit.

Focus on protecting high-quality split machines and cabinets of well-known brands to give full play to the energy-saving effect.

It is normal for the copper pipe of the air conditioner to drip water, this is because the outside temperature is high, and the temperature of the refrigerant flowing in the copper pipe is low, and the surface of the copper pipe will be condensed as soon as it is cold and hot, and it can be wrapped with insulation materials.

If the copper pipe is exposed, it will drip when the air conditioner is running, so wrap the copper pipe with insulation material.

It is very normal for water to drip at the copper pipe of the air conditioner, and there is generally evaporator reflux gas in the low-pressure return pipe. If you want to dispose of it, you can wrap it in insulation so that it doesn't come into contact with the air and it won't drip water.

If the copper pipe is exposed to the air, dripping is normal, and it is good to wrap it with insulation, and if it is not insulated, it is easy to condensate.

It is normal for the copper pipe joints of the air conditioner to drip water, and if there is no condensate in the maintenance valve (pipe joint) of the connecting pipe, the cooling effect of the indoor mechanism must be poor. Analysis of the cause of dripping water in the copper pipe joint of the air conditioner outdoor unit:

1. The copper pipe of the air conditioner is dripping, which is generally a low-pressure return pipe (that is, the thicker pipe), which contains the gas returning from the evaporator, which is still evaporating before flowing back to the compressor, but the strength is low, and the surrounding air humidity can condense and drip. The thinner tube is a high-pressure pipe, which contains high-temperature and high-pressure gas, which is generally heated, and the surrounding air will not condense and will not drip. So it's normal.

2. It is normal for the outdoor unit of the air conditioner to connect to the pipeline of the indoor unit, and there is dew on one copper pipe during operation; Dew at both copper joints is not normal, at least it means that the resistance of the high-pressure pipe is too great or the valve is not fully opened.

The solution to the serious dripping of the copper pipe of the air conditioner.

What is the cause of dripping copper pipe joints of air conditioners?

1. If you don't let it drip water, you can wrap it with insulation material and don't let it come into contact with the air. Do a good job of insulating the copper pipe of the air conditioner, and avoid the gas in it from contacting the air, then the problem of dripping water in the copper pipe of the air conditioner can be completely solved. The specific solution is to turn off the power of the air conditioner, so that the fabric or clothing that can play a warm effect is wrapped on the air conditioner compressor and the copper pipe of the air conditioner outside the unit, if after this operation, there is water seeping out of the copper pipe from the wrapping or freezing, then the air conditioner should be fluoridated.

2. Another cumbersome method is to find the elbow of the air conditioning water pipe and align it with the small hole at the low end of the air conditioner unit, so that the water droplets can be drained and the copper pipe of the air conditioner can be avoided.

It is normal for the outer wall of the copper pipe of the air conditioner to drip water, because the copper pipe is a refrigerant, and when the temperature of the copper pipe is low, it will condense water droplets when it encounters hot air outside. This is a normal physical phenomenon.

Dripping water at the copper pipe of the outdoor unit of the air conditioner, of course, is not normal, under normal circumstances, the indoor unit of the air conditioner will drip water outward where the water pipe is connected. The copper pipe of the external unit of the air conditioner should not drip water, at this time we can call the after-sales maintenance**, so that they can repair us smoothly.

First find out whether it is the condensate pipe tied to the copper pipe of the air conditioner dripping water, or the copper pipe condensation dripping. If the condensate pipe drips, the air conditioner is fine; If in the latter case, it is true that the copper pipe of the air conditioner is dripping, and the refrigerant circulation of the air conditioner itself is no problem, but the main reason may be that the copper pipe insulation layer is damaged or falling off, resulting in the partial evaporation of the refrigerant before the heat exchanger, and the "evaporation heat absorption" causes the copper pipe to condense - dripping; The secondary reason is that the filter screen of the heat exchanger of the indoor unit is full of dust, which greatly reduces the efficiency of the heat exchanger, so that the copper tube from the heat exchanger can continue to absorb heat, causing the condensation of another copper tube to drip. Based on the above analysis, 1

Reinforce the copper pipe insulation, 2, clean the filter screen, and the filter screen damages the heat exchanger a lot of dust, which must also be cleaned (find a professional).

It is normal for the copper pipe of the air conditioner to drip water, this water is condensation, find a basin to connect the water, and you will not wade around.

When the outdoor unit of the air conditioner is working, there will be condensation at the copper pipe of the external unit, which is normal and does not affect the normal use of the air conditioner.

Is it normal for water to drip from the copper pipe of the air conditioner? If there is a problem, what should I do? At this time, it may be abnormal, then you may have to find this air conditioner maintenance master to take a look and see what is the cause?

It is normal for the copper pipe of the air conditioner to drip water.

The copper pipe of the air conditioner is dripping, generally a low-pressure return pipe, which contains the gas returning from the evaporator, which is still evaporating before flowing back to the compressor, but the strength is low, and the surrounding air humidity can condense and drip water. It should be noted that there are water droplets in a normal state, but the freezing is an abnormal state, if the liquid pipe is frozen, a large amount of water is produced after the ice melts, which is due to the lack of refrigerant, resulting in the reduction of refrigerant fluidity, and the accumulation of refrigerant in the liquid tube evaporation.

If there is no condensate in the copper pipe of the air conditioner, the cooling effect of the indoor machine must be poor. After the refrigerant is cooled by the fan of the outdoor unit, the refrigerant undergoes depressurization and cooling changes through the throttling pressure reducing device, and the low-temperature refrigerant may be below 10 degrees Celsius, or even close to 0 degrees. At such a low temperature, the contact with the air through the copper pipe will cause the moisture in the air to condense into water.

The solution to the dripping water of the copper pipe of the air conditioner

It is recommended to do a good job in the insulation of the copper pipe of the air conditioner, and avoid the gas in it from contacting the air, so that the problem of dripping water in the copper pipe of the air conditioner can be completely solved. The specific solution is to turn off the power supply of the air conditioner, so that the fabric or clothing that can play a warm effect is wrapped on the copper pipe of the air conditioner compressor and the air conditioner external unit, if after this operation, there is water seeping out of the copper pipe from the wrapping or freezing ice, then the air conditioner should be fluoridated.

If the air conditioner needs to re-install the condensate pipe, you can also add a condensate lifting pump to the indoor unit of the air conditioner; If it is an air-conditioner, you only need to lower the condensate pipe, of course, if the air-conditioning hole is too high, you can increase the height of the air-conditioner unit or re-dig a lower air-conditioning hole.

Hello, it is a pleasure to serve you, it is normal for the copper pipe joints of the air conditioner to drip water. In the case of high humidity in the external environment, if there is gas refluxed from the evaporator in the low-pressure return pipe of the air conditioner, it will often condense into small water droplets, which will cause the problem of dripping copper pipe of the air conditioner outside the unit, but this phenomenon is relatively normal, and it is relatively easy to maintain, only need to wrap the waterproof tape around the interface between the air conditioner and the copper pipe, so the phenomenon of dripping water at the interface between the air conditioner and the copper pipe does not have to worry, it is a normal phenomenon.

The thick pipe is the return pipe, the gas superheat back to the compressor is low, and there will be water on it in contact with hot air, such as high superheat, that is to say, the high temperature of the gas coming back is about the same as the air, and there will be no condensationThere is water in the thin tube, and the thin tube becomes a low-temperature and high-pressure night body after passing through the condenser, and it is evaporated and refrigerated after the capillary tube in the evaporator, so the thin tube will have dew in contact with the atmosphere at low temperature

If the valve of the liquid pipe is frosty, it means that the fluoride deficiency is serious; Only the tracheal valve is frosty, indicating a slight lack of fluoride or the ambient temperature is too low; Both valves are frosted, indicating that the system has secondary throttling.

Normal! The more water comes out of the connecting pipe of the high and low pressure valves of the air conditioner, the better the refrigeration effect.

Frost on the connecting pipes of the high and low pressure valves of the air conditioner's external unit, indicating that the refrigeration system lacks fluorine.
