How to deal with the dripping phenomenon in the condenser pipe of the external unit of the air condi

Cause analysis: air supply system.

If the filter screen is dirty and blocked, and a low air stall is used in a humid environment, if the air volume is small, the evaporation temperature of the internal machine will be reduced, and the evaporator will frost or even freeze, resulting in water leakage for a long time.

drainage system. Mainly including the front and rear of the inner machine water trough, drain pipe, pipe wrapping, drainage pump failure, etc., when the air conditioner is used for a long time, the water guide trough, the drain pipe may be blocked by dirt leakage, the water guide groove and other cracks due to injection molding, the connection pipe joint is not good, and the drainage pipe will be flattened when installed will cause water leakage.

The system lacks fluorine and the evaporator is half-blocked.

In the case of serious fluorine deficiency in the system, the refrigerant is quickly vaporized in 2-3 long U tubes close to the input tube when it enters the evaporator, so the temperature of the 2-3 long U tube fins near the input tube of the evaporator is low, while the temperature of other long U tube fins is close to room temperature, so a large amount of condensate will condense on the 2-3 long U tube fins close to the input tube, and it will freeze after a long time. In the case of the evaporator being half-blocked, the temperature of the long U-tube fin with a large refrigerant flow is low and the temperature of the long U-tube fin with a small refrigerant flow rate is higher, resulting in a large temperature difference between the two flow paths, and the long U-tube fin with a large refrigerant flow condenses a large amount of condensate and blows out with the wind, and because the cold and hot air meet in the air duct, the water vapor condenses in the air duct, and finally leads to water leakage.

Installation issues are causing water leaks.

It is mainly concentrated in newly installed units, or air conditioners installed in winter, due to the installation is not horizontal or the drainage pipes and connecting pipe joints are not properly bandaged.

Solution 1:

Clean the filter, install it, and explain to the user to pay attention to regular cleaning and maintenance. After maintenance, the maintenance method of the air conditioner should be introduced to the user, and the filter screen should be cleaned regularly, in addition to the evaporator frosting and the system less fluorine frosting is easy to confuse, the system less fluorine frosting will only be locally frosted on the evaporator, generally at the inlet end of the evaporator, and the filter screen is dirty and blocked and frosting will even appear in the return pipe (low pressure pipe) of the system, and it will be judged correctly when processing.

Solution 2:

Convert the low gear to a high gear or (auto) and set it to 24 degrees so that there will be no condensation. The above faults are actually caused by physical factors, and the explanation can be sufficient. Blowing out "water mist" (fog water) occurs more often during the "rainy season", and it is more likely to occur in the south when it is rainy, the air pressure is low, and the humidity is high.

Therefore, when dealing with such problems, first check whether the evaporator is dirty and whether the rotor blades are dusty, and then set a high wind gear and a high temperature as much as possible.

It is normal for the condenser pipe outside the air conditioner to drip because of the heat insulation, or the effect of cold insulation is not good. You can add some insulating mats or insulation layers at the back, etc.

The dripping pipe is not called a condenser pipe, but the connecting pipe of the internal and external units of the air conditioner, and the connecting pipe has some dripping, indicating that the temperature in the air conditioning pipe is low, and whether there is a slight lack of fluoride can be considered.

In fact, it is normal for the condenser pipe of the external unit of the air conditioner to drip water. You can wipe him with a rag.

You can use an insulated pipe to wrap it.

Ordinary people, if you call her dripping, then test the moisture in the air for you, and if you touch that thermometer, you will give it to you.

You mean that copper head drips, right? This is normal, and if it doesn't drip, it's broken.

The dripping water of the refrigeration unit is normal. This is due to the fact that when the air conditioner is cooling, the outdoor machine defrosts and produces a large amount of water, or because of the temperature exchange, which produces condensation. Sometimes, in order to save time, air conditioner installers do not install plastic drains, which causes water leakage in the outdoor unit of the air conditioner.

In this process, the refrigerant of the air conditioner will produce cold work under the operation of the compressor, and the temperature of the pipeline responsible for transmitting the refrigerant is relatively low, and the water vapor in the air will liquefy into water when it contacts the pipe or condenser, so it will drip water.

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.

First of all, analyze the cause of dripping, the indoor temperature is high, and the air containing more water vapor enters the air conditioner, and after being cooled, the air temperature drops, and the water vapor that can be contained decreases, and condensation appears, forming water droplets dripping down the drain pipe. The greater the refrigeration capacity, the faster and more water will drip out; For the same cooling capacity, the air humidity is high; So, a dripping air conditioner is normal, and vice versa. Congratulations, your air conditioner is working properly.

When the air conditioner is refrigerated, it is normal for the copper pipe joint of the outdoor unit to drip water, because the air conditioning pipe conveys cold gas to the indoor unit during refrigeration, and the surface temperature of the copper pipe is very low, and the water droplets will not be refrigerated if the water does not drip.
