What to do if the air conditioner leaks
Many air conditioner owners are faced with a situation where water starts dripping from the indoor unit. The liquid can flow directly from the case, along the wall on which the equipment is installed or through the louvers along with the air flow. Usually the problem is observed not immediately after turning on the split-system, but 20-40 minutes later. The volume of water depends on the difference between the set cooling mode and the ambient air temperature. The greater the difference, the more the air conditioner leaks.
When the air conditioner works for cooling, water is formed in the internal unit. condensate. Condensation. is the moisture in the air that condenses (settles) on the surface of the heat exchanger of the air conditioner whose temperature is below the dew point.
The dew point is the temperature of the air at which the steam (moisture) it contains reaches saturation and begins to condense into dew.
If conditioner works properly, and the main thing is that it is installed qualitatively, the condensate is safely removed outside the premise. It happens either by gravity (the drainage is laid with a slope) or by force (when using pumps, pumps, etc).п.)
Here are a few more notes and tips from professionals who install, tune, and repair refrigeration appliances. In general, they name the most widespread reason that conditioner is leaking. clogging of drainage reservoir. If you neglect its service cleaning, it will eventually get clogged. Dirt, wasps, spiders and other insects get inside the tube. The question that often arises is what the insects are doing inside the tube? They, like all living things in summer, are attracted to water. Some people even live there. The owners of ingenious conditioners sometimes put mosquito nets on the end of a pipe, but it becomes clogged with time, too.
As diameter of the hole of drainage tube is about 1 cm, and it is clogged, when split-system is working, the water drops through the indoor unit in the apartment, not through the tube on the street. It is better to entrust the problem of cleaning to professionals. After disconnecting the air conditioner and after its flushing the problem will be completely eliminated, the drainage system will be cleaned.
Often an independent human factor is to blame for water dripping from the enclosure. So, during repairs, you may need to move it a little higher, lower, or to the side (especially when repairs affect the ceilings in the room). In this case, if it is done without the participation of specialists, it may change the angle of the drain, and the water does not flow outdoors, as it should, and drips into the room. Do not do without the participation of workers service, t. к. you have to drill a new hole and re-route the utility. In addition, during popular nowadays high-rise works on insulation, industrial climbers, as experience shows, can and putty plastered drainage (if the neighbors dripping from above), and bend up the end of the drainage pipe. Here, of course, to fix the leak, you need to redo the intervention of careless workers.
Diagnosing An RV Air Conditioner That Is Not Cooling
Breakage or breakage of connections
Between the tray drain and the drainpipe there is usually a spigot. Sometimes it can crack, break off, or come off the tubes. It is a flexible hose that is fixed on collars or clamps.
Open the lid of a conditioner and look at the right and left part (depending on a variant of installation) on a condition of the branch pipe. If it is a problem and it leaks water, you need to change it.
Do not look for the original tube you will spend your money for nothing. In any plumbing store or on the market buy the same diameter and fix it with the usual plastic clamps-straps.
If the old branch pipe was fixed with the help of clamps wrap them or the branch pipe itself with fum-tape. After that put on a new one.
Why the water flows out of air conditioner??
At first it is worth to say a few words about the construction of air conditioner and then to deal with all questions that concern peculiarities of its work. In any air-conditioner there is a part of a refrigerating contour with temperatures which are much higher than the temperature of ambient air. This hotter part is usually called the condenser or outer unit. It is always outside the room and has a direct contact with the outside, street air. The other part of a conditioner is installed in the room where it is necessary to cool air. It is the coldest place of refrigerating circuit. It is called. evaporator or indoor unit. These two blocks are united with copper pipelines and electric wires, and such construction is called a split-system.
Another design of air-conditioner can be called a monoblock conditioner. In this case, the external and internal units are placed in the same enclosure, but still its condenser is directly outside the room and is in contact with outdoor air, while the other part is indoors. It is more often is inserted into a window, more seldom. into a wall.
The question: “Why the water flows from conditioner??” is more about split-system, that’s why we will talk about it.
Let us consider a concrete example. Suppose there is an air conditioner in the room. When it’s hot outside, it is turned on to work in cooling mode. The cooling agent that circulates in the system, boils in the exchanger of the indoor unit, has a temperature well below the air temperature in the room. Due to this reason the exchanger, or more exactly the external surface of heat exchanger tubes, starts getting covered with moisture, which becomes more and more, and it starts trickling down and collecting in the tray. This is precisely the purpose of such a tray, which is installed under the heat exchanger of the internal unit. To remove this water there is a special spigot in the sump, which is connected by a hose or pipe. The water is discharged either into the sewage system or into the street. There is no way to avoid the formation of this water. Its formation is connected with the peculiarities of air conditioner work in a cooling mode. If the whole drainage system was originally done correctly and is working properly, you do not have to worry. If for some reason water starts to drip from the indoor unit, it means that there are violations that led to it.
As mentioned earlier, the water from the tray must be drained through a drainage pipe to the sewer or outdoors. often than not, water flows by gravity. To do this, along the entire route of the pipeline there must be a slope of at least 1 cm for every 100 cm. 1.1. If the slope is not maintained, then there is an accumulation of water in the drainpipe, in the pan and the water from the pan begins to drip out. It often happens when condensate is taken out to the street and a drainage pipe has to be laid through a hole in the wall. The hole is also drilled with a slope towards the condensate outlet. Often this is neglected and drilled such holes horizontally. Of course in this case the water simply will not flow down the pipeline.
- during installation, dirt, dust, pieces of construction works can get into the tray and then with the flow of water will get into the drain pipe. This can result in partial or complete blockage of the flow of draining water.
- Water can drip or leak not only from the indoor unit area but also from outside the unit. This can occur if the drainage pipe is damaged in some way and condensation water partially flows out at this place. A similar pattern can be observed if the drain line has a joint or connections along its entire length. Condensation water can also leak at bad connections.
- In some cases it is not possible to make the drain piping so that the required slope is maintained all the way down. In this case, you must install a drain pump (pump) to continuously or periodically pump the condensate out of the sump. In case of its failure, condensate can also accumulate in the piping, and finally in the sump itself and drip outside.
If the air conditioner started dripping water from the indoor unit during prolonged operation, the reasons may be, the following:
- Water is known to be a breeding ground for mold and other microorganisms. Therefore, after some period of operation of the air conditioner, dust, dirt and other types of organic contaminants begin to accumulate in the sump. Similar condensation can occur in a drainage pipe. If preventive cleaning is not done in time there will be problems with condensate evacuation or even clogging of the drain, which leads to water accumulation in the sump and to its overflow. A related phenomenon in this case can be a strange odor on the side of the inner unit. To avoid this phenomenon, there are routine maintenance tasks for the indoor unit. During such work, the heat exchanger of the indoor unit and the condensate drain pan are cleaned. For this purpose, special means of cleaning are used. Such work can be carried out with the help of specialists from the company, as well as yourself, if you have the appropriate skills.
- air conditioner operation is accompanied by slight vibration, that is why in some time insignificant leaks can appear in the places of bad connection of the drain pipeline that will cause water condensate leakage.
- if a split-system operates on cooling at negative temperatures and a drainage pipeline is situated outside, it is necessary to take into consideration that condensate can freeze in the drainage pipeline, a water overflow in the drainage pipe and it will flow out. To prevent such situation a special heater is installed in a drainage pipe, which does not allow to form an ice plug in the pipe in winter time.
- When the air conditioner is operating in the cooling mode, the heat exchanger of the indoor unit should under no circumstances be frozen, covered with frost or ice. If this happens suddenly, after turning off the air conditioner, the ice crust will thaw. Since the size of the ice build-up can exceed the overall size of the heat exchanger, water can flow past the drip tray and beyond the body of the indoor unit during defrosting. Frosting can appear because of different reasons: insufficient quantity of the refrigerating agent in the refrigerating contour, wrong using of the conditioner when the temperature in the premise is lower than the temperature for which the conditioner works and high humidity in the premise. In this case it is necessary to ask the specialists to remove the defect that causes the heat exchanger to freeze.
Causes of water leakage from the outdoor unit :
Insufficient quantity of refrigerant. To solve this problem it is necessary to charge the unit with the refrigerant.
Contamination of the evaporator. To stop the leakage, the evaporator must be cleaned of debris.
Because of the pressure drop in the freon pipeline (the lowering of the ambient temperature leads to this) water can also leak from the module located in the street. In order to avoid such problems in the future, you should install a regulator that will maintain the pressure at the required level.
Sometimes a leaky unit can be a normal phenomenon. You may notice water leaking out if the appliance is running in cooling mode for too long or if you use it for heating.
To avoid problems when draining the liquid, a hose is installed in the lower opening of the module. If the liquid is leaking even though the drain hose is present, it may indicate that it is clogged. In such cases you have to clean.
Why the indoor unit can leak and how you can fix it
Air conditioner leaking water. How to fix
The inside of the system can leak for a variety of reasons. Let’s consider them in more detail and find out what methods can be used to solve the problems detected during the operation of equipment.
How to deal with it
Appealing to cleanliness is not enough. Anyway there is dust in the air and it is sure to get into the system. The manufacturer has taken care of this by installing strainers behind the grills.
And it is necessary to keep these filters clean. At the end of the season or, better, once a month the nets should be taken out of the case, washed and dried. In addition, the radiator heat exchanger (fins) must be flushed periodically. If the drain is not blocked, the dirty water can easily get out.
Similarly it is necessary to clean the turbine of the fan. On the blades gets the same dust, and it can lead to vibrations and breakage.
The condensate pan itself, is an excellent waste pit. Heavy dust particles settle to the bottom, and serve as an excellent template for the formation of a jam at the inlet to the drain. Again, before the start of the season it is necessary to clean the inside of the housing.
Preventive maintenance of drainage system
Without waiting for a flood from the indoor unit, it is necessary to regularly clean the pipe that connects the two modules of the air conditioner. To do this, you can use a clogging agent in the sink, an enema (creating a head of water), a beach mattress pump. Pour a glass of water into the condensate pan to test for drainage. The liquid should disappear in a few seconds.
Check the condition of the outside of the drain. If the flexible pipe outside the wall is dangling in the wind. fix it.
Be sure to check the drain connection to the outer tube for leaks before the start of the season. A couple of meters of sealed film costs pennies, unlike ruined wallpaper on the wall.
