Why is the water not leaking from the air conditioner?

Water leaking from the air conditioner into the room. what to do

So, let’s break down the causes of air conditioner leaks and solutions. Of course, it is best to call a specialist to the house, but some actions can be performed yourself:

  • If we are talking about the first reason, you may not even need a handyman here. It is enough to pour out the excess liquid from the accumulator, insert it into the previous position, after which the technique will once again work as it should. It is important to turn off the power supply beforehand. Also remember to watch for the slightest leakage later on.
  • One of the reasons why the air conditioner leaks is a result of ice. it makes sense to do thermal insulation. For example, to avoid temperature drops, you can use glass wool.
  • If the cause of failure was the pump. it should be repaired, if possible, or replaced. Without proper experience it is difficult to do this, so it is better to apply to the masters.
  • If the corrugated hose is not positioned correctly, it is enough to place it at the proper angle.
  • Pipes will be strengthened if it is better to tighten them with nuts and use a sealant on top of treatment. Here it is important to act delicately so as not to tear the threads.

Even if split-system is repaired. do not forget to monitor that there are no excessive accumulations in it, and in future it will not leak anymore. Prophylaxis in the case of conditioners is always very important.

Part of the causes, due to which conditioner is dripping in the room, can be quite corrected by oneself. As for complicated defects it is better to entrust them to the masters who know about it. For example, if the internal block leaks, it is impossible to do without special knowledge and tools. In general, this applies to most of the internal failures, which are not visible to the naked eye.

Causes of water leakage

The essence of work of split-system consists in cooling/heating of air in the premise due to redistribution of heat from the outer block to the inner one (and vice versa). This process is realized by circulation along the closed line of system the special coolant. freon which changes its aggregate condition from liquid on gaseous as the result of pressure and different temperatures. When operating in a cooling mode, when the refrigerant takes the heat from the premise to the environment, the condensate forms on the heat exchanger plates of the indoor unit and runs down the drain pipe. Heat transfer occurs in reverse direction in heating mode. In this case, condensate forms on the walls of the heat exchanger of the outdoor unit and runs down the drain hose.

Important! The water leaking directly from the indoor or outdoor unit is the evidence of split-system malfunction. But having no idea what to do when the conditioner is leaking it is not recommended to start disassembling and examine it by yourself.

Leak from indoor unit

Leaking air conditioner in the apartment can cause damage to walls and flooring. To prevent imminent damage, you should identify and repair the fault as soon as possible. So, the most common reasons for the formation of a leaky indoor unit:

Leakage from the outdoor unit

Drain hose pipes are located directly next to the outdoor unit. If split-system is perfectly normal, in some time water is pouring out of them, and it is very hard to catch the fact that it is outside unit, that is leaking. If it happened, and an external inspection confirmed that the leak is not caused by natural causes, the provoking factors may be:

  • Freon shortage;
  • clogging of the evaporator;
  • Failure of pressure regulator;
  • Heat sink damage as a result of mechanical impacts.

The peculiarity of air conditioner functioning implies formation of condensate, which accumulates in a special tray and then flows out through the pipe to the outside or to the drainage hole. And if one day you notice that the condensate does not come out, you should pay close attention to this moment. In some cases the conditioner can need repair.

However, in some situations, there should be no condensation. In particular, the above-mentioned liquid is absent if “fan” mode is not activated or if the base temperature in the room is almost the same as that set in the settings of the equipment. There may also be no condensate for half an hour after the unit is turned on, because the water accumulates for some time and only then begins to flow out.

How to beat a neighbor with a dripping air conditioner

I decided to write about my struggle since there is very little information. I myself probably killed a whole day reading forums and different reviews.Unfortunately in our country there is no any regulations of air conditioners installation. You can duct tape the whole wall. It could be staggered.If your air conditioner or low tide behind the window drips from the top, it’s of little concern to anyone. And mean-spirited air conditioners don’t even look where they drain the condensate. If they do it at all, like they did in my case.I live in a regular house with 9 floors on 6. Under the roof, the owners rent out the apartment. Last year there was one air conditioner. In this one it became 2. And that’s it. As soon as the summer came, it started to pour. And on my unit and the window and the neighboring window in the kitchen. And the neighbors downstairs, too. Conversations with the tenants had no effect. They would not open the door. But gave the phone number of the owner of the apartment.It should be noted that on the 5th floor live strange characters. It’s been pouring on their air conditioner for years. There’s a rusty stain on the unit the size of a giant plate. Why they didn’t itch before I don’t know.It was pouring especially hard at the arrows.

There wasn’t any tubing with any outlets at all. It was just pouring out of the wall and under the block there was like 10 centimeters of pipe. And it wasn’t even going over the edge of the block.Returning to the landlady, I want to note that the woman was not adequate. Started telling me all her drains were fine. She invited someone over and got it done. I sent her some videos. It took 3 or 4 days and it stopped pouring from the wall. I didn’t get any from the condyoners. It was dripping so bad, I was up till 3:00 in the morning. Covered the unit with carpeting on top. But that only helps until it gets wet. Then you hear them dripping again. But of course it’s much quieter when the drops are drumming on the iron.I started negotiating with the landlady again. It lasted literally half a day. Further madam has made it clear that if I do not like something I can call anyone for my money and do the plums as I want. In her air conditioners! It hadn’t bothered anyone before me, you see.

After the word Go ahead! I realized that there’s nowhere to retreat behind Moscow, as they say. I will say that the precinct did not get. And the tax authorities it was necessary to send a request through him just. But as far as I found information about this madam, she officially rented the apartment. And here I would not have nailed it in any way.

Went to talk to the neighbors below. They fully supported my initiative. The upstairs neighbor was away for a long time and unfortunately didn’t participate. But he was all for it. And he confirmed that it’s a long-standing problem. Once again, I do not understand why they did not try to solve it.

After much searching on the Internet I found this text of the application to the Head of the repair. maintenance area. The point is that as much as possible begin to describe that in addition to your suffering is causing damage to the facade of the house.

The downstairs neighbor was very creative with the wilting. Rolled for 2.page 5. She took a picture of her rusty air conditioner and vividly described the suffering of her family and especially her pregnant daughter.Next I took the letters. All accepted. They put the numbers in. It’s just like it’s supposed to be. Within a week the technician had arrived. Looked at the full extent of the tragedy. It’s a good thing I came when it was hot. At other times the condensers didn’t drip or drip not so much.And then I went out of town for two weeks. On my return I met a happy neighbor. All the drains have been redone. They put corrugations everywhere and we’ve practically got rid of the drumbeat. Sometimes it drips, but just a little. The landlady could not find an air conditioner with straight hands. I would have made the tubes longer.I just really wanted to write this madam that for every sly ass, including hers, there is always a bolt with a thread 🙂 But I held back 🙂

Air conditioning and the lack of condensation. The theory of cold on your fingers.

Good health to all mentally, morally and physically!I spent two days to study the material on air conditioners and automobile air conditioners in particular. It became a custom in our country, and not only in our :(, that if you want to do well, you have to understand all the subtleties of matter, find your own ways of solving and implement.Having dug through a lot of materials I found the best “work” which, in general, describes how it works and what will happen in the most simple and accessible way. What follows is the author’s text:

One of the most important characteristics of a refrigerating circuit is the value of superheat of vapor of the refrigerant at the outlet of the evaporator.vapor superheat is the difference between the temperature of the vapor and the temperature of vaporization of the liquid from which the vapor is formed, at constant pressure.For evaporators, the superheat is the difference between the temperature measured by the TRV thermobalance and the evaporating temperature corresponding to the pressure gauge reading (in most cases, the pressure loss in the suction line can be neglected due to their smallness).

How to Fix Wall Air Conditioner AC Water Leak

In the example in the illustration, the superheat is 7 K.

In direct expansion cycle evaporators, it is generally assumed that the superheat should be between 5 and 8°C.

When the superheat is outside the normal temperature range, it often indicates an abnormal process flow.

Therefore, below we will analyze different cases of anomalous overheating of the evaporator:

Excessive superheating (typically above 8 K) tB = tE = vaporization temperature = 4°C

If the temperature of point D is 18° C, the superheat is 14 K.

During normal operation of the refrigeration circuit, the last liquid molecules evaporate at point C.

As they continue to pass through the evaporator (point C-D), the vapors heat up. If only the CD section is filled with vapour, this results in a normal superheat (e.g. 7 K).

water, leaking, conditioner

If there is a shortage of refrigerant in the evaporator, when the last molecules of liquid evaporate, for example at point E, the length of the pipeline section filled only with vapor increases (in the figure it is section E-D), which leads to significant overheating. Measurement of the temperature at point D may give 18°C, i.e. the superheat will be 14 K.

If the superheat is too high, the orifice of the expansion valve is nearly closed and allows very little liquid to pass. The cooling capacity of an evaporator containing little liquid is low and the temperature difference between the inlet and outlet of the cooled air is very small. Evaporation pressure has dropped and frost forms on the outside of the pipe at the nozzle of the expansion valve.

Excessively low superheat (usually below 5°C)

In the diagram, the temperature at point B is equal to the temperature at point D, i.e. the evaporating temperature is 4°C..

If the superheat is too low, the orifice of the expansion valve is completely open and is allowing too much liquid in. Because the evaporator contains a lot of liquid, the cooling capacity is high and the temperature differential for the cooled air appears normal, but liquid particles can enter the compressor. This mode is extremely dangerous because it is fraught with hydroblocks in the compressor and can cause serious damage.

In short 🙂 now my thoughts why the condenser freezes, but there is no condensate. Because of small quantity of freon, it has time to evaporate already in point E and the section E-D heats up this condensate and it simply evaporates!To know for sure you need to measure return temperature from evaporator!

My return tube is sweating! Т.е. the evaporator doesn’t sweat, but the tube does 🙂 MISTICS! And by logic, the temperature of a properly working evaporator can not be below 4 degrees.There are a few options:1. I have to refill 100-150g of freon with this stuff.2. Wash the evaporator with a foam cleaner, t.к. there is a version that the condensate is absorbed in a moss on it 🙂 and simply does not flow :)3. To hammer in a bolt and to drive thus 🙂 in fact the conditioner freezes all the money 🙂

Which option will YOU, dear readers, choose??

There’s also a way to charge by pressure and tables. Roughly speaking when the condenser is on, in the high pressure part, the pressure rises and is from 1200 to 1500 kPa, for simplicity of understanding is 12 and 15 atm. In the low pressure area, the pressure per revolution drops to about 100-150 kPa. Now the most interesting thing! When the air conditioner is off, the pressures in the high and low parts compare and freeze around 800kPa! about 8 atm! But again, there’s a catch! This pressure is very much dependent on the environment! At 35 it is just about 800kPa at 20 it is already 540kPa.

Where does the unnecessary liquid come from??

Cooling of air in the air conditioner is done by circulation of refrigerant. The element of the flow chart where the temperature drop occurs is called the evaporator.

This appliance is so-named because during operation the moisture drops, i.e. “evaporation”, appear on its casing. This formed liquid is that very condensate, which requires drainage from split-system unit.

Drainage of accumulated moisture is the important moment for proper operation of air conditioner. The air handling unit is operated by the mains. As you know, water is a good electrical conductor. At high humidity there is a risk of appliance circuit short circuit. Breakdown of expensive electrical equipment can be prevented by proper drainage of condensate.

The outdoor unit of the air conditioner is leaking: causes, how to fix it

Some owners notice condensate leaking from the outdoor unit. Let’s take a look at what causes this and how to fix the problem.

Causes of condensate leaking from the outdoor unit:

  • Low refrigerant level. Such malfunction is solved by refilling the split-system with freon.
  • Contaminated evaporator. For elimination of this problem it is necessary to prophylactic cleaning of the evaporator.
  • Pressure in the refrigerant line decreased because of a drop in outside temperature. It is recommended to install a pressure regulator, which will prevent similar malfunctions in the future.

A drain hose can be installed in the lower opening of the unit for safe drainage of the liquid. If it is already installed, but water is still leaking from the unit, there is a chance that the drain is clogged with dirt and needs to be cleaned.

Drainage of condensate from the conditioner

The process of condensate drainage itself can be carried out in the following ways:

water, leaking, conditioner
  • Simply lead the pipe to drain the liquid into the street through a hole in the wall. This method is used because of its simplicity. you only need to drill a hole and bring the hose out the window at the required slope (at least 1 cm per 1 meter of length). However, this option can’t be called correct because of the side effects. Water dripping from the tube will drum on the window sills of the neighbors below, and this is fraught with accusations on their part. It is forbidden by sanitary regulations to lead the pipe out in this way. In addition, such a design affects the aesthetic sense and spoils the overall view.

Maintenance of the drainage system

There are a number of malfunctions that can occur during operation that need to be solved in a timely manner:

  • The most common problem is a clogged hole, through which the moisture is drained from the special container into the drainage tube. This occurs because of the usual dirt and dust, which clog the hole, settle, penetrate into the tube, clogging it. Because of this, the liquid overflows into the tub and starts leaking onto the floor and walls.

To avoid all unpleasant consequences it is necessary to monitor the state of pipe and in time to clean and wash it. Experts recommend the use of detergents that contain chlorine, as they do a better job.

To prevent this from happening. It is necessary to switch off split-system in cold season (when the temperature is lower than 0C), or to get special low-temperature complete set, which provides compressor and drainage pipe heating and allows to conditioner to work at the temperature till.25°С.

A slope, at least a small one, is mandatory along the entire length of the tube to avoid stagnant water.

That’s why the manufacturers recommend to buy the equipment from the reliable suppliers and to treat the installation with responsibility.

To avoid it you should watch the level of the refrigerating agent and with the required frequency (defined in the conditioner manual) to address to the service-center for refilling.
