Condensate drainage from air conditioning
Today, air conditioning is a popular element in many houses and apartments. It is used for cooling or heating the premises to provide a comfortable atmosphere for residents.
However, in the process of operating the air conditioning evaporator, a condensate appears, which must be removed. In the article, we consider why it is important, what problems may arise if the excess fluid is not removed, and how to do it correctly.
Why is condensate and what is its danger
Air conditioning is an evaporative device that cools or heats the air in the room. In the process of its operation, the refrigerated agent used, which in the process of circulation along the refrigeration contour changes its physical parameters and its aggregate state with condensation and boiling. The last process occurs in the evaporator, which, in turn, cools the air. At the same time, the heat exchanger of the evaporator from the air is covered with droplets of liquid. condensate (or moisture). Excess moisture drain is an important point to ensure the quality of the air conditioner.
Excessive inevitable moisture in the air conditioner can affect his work. In addition, bacteria, fungi, mold and other microorganisms are developing in stagnant water. All of them can cause diseases of the respiratory system, poisoning. Not to mention appearance and unpleasant odors.
If under a puddle car, with a working air conditioner, then this is not at all an indicator that the drainage of the air conditioner is clean and not clogged with mud.
For 2 years of operation of Megan, condensate always dripped under the machine with the climate turned on. Having read about how, after long trips, people in Renault Megane 2 had a puddle under the feet of the front passenger, I decided not to wait for a puddle in my car and make an audit of this drainage of the air conditioner. I made an audit exactly half a year ago (in winter I prepared a sleigh for the summer). He took off the air duct-tube onto the mess and through that the hole inserted a silicone hose with an outer diameter of about 10 mm and groping for a drainage hole, the compressor supplied a pressure of 8 kgf/cm² there by the compressor. A cloud of dust rose from under the car and I decided that with the drainage I did not have everything like everyone else.While the mess was removed, I decided to finalize the seat for the salon filter. I was not satisfied with the fact that the filter is standing, and does not fully fulfill its functions. When the stove fan is turned on at full power, it was evident how not just dust flies out of the ducts, but large particles of dust with small snorkes. When examining the seat of the salon filter, I saw that dust and garbage flies into the gaps between the body of the filter itself and the box, where it is inserted. I found a white (D-shaped) door seal in the garage and put it in a haste at the perimeter of the seat.
At the next disassembly, I will stick a new one, so that there were no cracks between the strips of the seal.
And so, two days ago, after a long trip with climate and increased air humidity on the street (about 80%), when leaving the car, my father asks me: “What kind of water is it on your rug?”I immediately realized what was the matter, without even looking from where it dripes and turned off the climate. I looked under the car. condensate drips. Went to the store, returned after 10 minutes, and the water under the car is still dripping. I went to a garage with a climate turned off (the good is Luke with a panorama). I drove up to the garage, looked under the car, and the water is still dripping (total: 25 minutes drained water). He took off the mess, bent the carpet, and under it only 2 drops (he took over the rubber rug with high sides) of all the water) easily escaped.I tried to pull out the fungus without cutting the nozzle of the foam, but this is almost impossible to do, and if it happened, then it is definitely impossible to put it right with Shumka! Cut Shumka and bent to the sides.
How to defeat a neighbor with a dripping air conditioner
I decided to write about my struggle since there is very little information. I myself probably killed all day reading forums and various reviews.К сожалению у нас в стране напрочь отсутствует какой либо регламент установки кондиционеров. You can drop the entire wall. At least in a checkerboard pattern.If your air conditioner or tide is dripping outside the window on top, then this is not worried about. And handwritten air conditioners do not even look where they are draining condensate. If at all, it is done as it was in my case.I live in an ordinary house on 9 floors, at 6. Under the roof, the owners rent an apartment. Last year there was 1 air conditioner. This was 2. And all. As soon as the summer has poured. And on my block and on the window and on the next window in the kitchen. And on the neighbors floor below too. Conversations with the tenants of the apartment did not have any effects. They did not open the door. But they gave the phone number of the apartment.It should be noted that strange characters live on the 5th floor. They have poured on their air conditioning for years. There is a rusty spot on the block with a huge plate. Why they didn’t scratch before I don’t know.Poured especially strongly where the arrows.
There were no pipes with the dumps from the word at all. It was just poured from the wall and under the block the tube was 10 centimeters. And she did not even go beyond the boundaries of the block.Returning to the mistress of the apartment, I want to note that the woman was not adequate. Began to tell that all the plums were in order. She invited someone there and did everything. I sent her a few videos. 3-4 days passed and stopped pouring from the wall. But from the conditioners there is no. Dripped so that I did not sleep until 3 nights. Covered the block on top with carpet. But this helps only until it is wet. Then again you hear how it drip. But of course much quieter when drops drum on the piece of iron.Negotiations with the mistress began again. They lasted literally half a day. Then Madame made it clear that if something does not like something, for my money I can call anyone and make plums as I need. In her air conditioners! Before me it did not interfere with you.
Dare off after the word! I realized that there is nowhere to retreat behind as they say. I will tell the rhinest that it did not reach the district police officer. And the tax authorities had to send a request through him just. But as far as I found information about this madam, she officially rented an apartment. And then I would not press it in any way.
I went talked with my neighbors below. They fully supported my initiative. The neighbor was in a long departure and unfortunately did not participate. But he was entirely for. And confirmed that the problem is long. Once again I did not understand what then they did not try to solve it.
After a long search on the Internet, I found such a text of the application addressed to the head of the repair site. The bottom line is that we begin to describe as much as possible that in addition to your suffering, the facade of the house is damaged.
The neighbor from the bottom very creatively approached the ending. I rolled on 2.5 pages. She attached a photo of her rusty air conditioner and described the suffering of her entire family and especially pregnant daughter in paints.Then I attributed letters. Everyone accepted. They set incoming numbers. Everything is as it should. The technician came within a week. I examined the entire scale of the tragedy. It’s very good that it came when it was hot. At other moments, the conders did not drip or dripped not so hard.And then I went out of town for 2 weeks. Upon returning, I met a joyful neighbor. All plums were converted. The corrugated corrugated everywhere and we practically got rid of this drum fraction. Sometimes dripping but just a little. The owner of the apartment was never able to find confectioners with straight hands. I would make the tubes even longer.I really really wanted to write to this madam that for every cunning ass and in that more and there will always be a bolt with thread 🙂 But I restrained myself 🙂
Air conditioning and lack of condensate. Cold theory on the fingers.
Health of all spiritual, moral and physical!I spent two days on studying the material on air conditioners and automobile air conditioners in particular. So it happened in our country, and not only in ours: that if you want to do well, then you have to understand all the intricacies of matters yourself, find your own solutions and pretend to be in life.Having shoveled a bunch of materials, I found the optimal “labor” in which, in general, it is generally as simple and accessible as it works and what will happen and what will happen. Further author’s text:
One of the most important characteristics of the refrigerated circuit is the value of NEPEGPEVA vapor of the refrigerant at the exit of the evaporator.A steam overheating is the difference between the temperature of the steam and the temperature of the evaporation of the fluid from which this pair was formed, with constant pressure.For evaporators, overheating of the steam is a difference between a temperature measured using a TRV thermoballone and the temperature of evaporation corresponding to the indications of the manometer ND (in most cases, pressure losses in the absorption pipeline can be neglected due to their smallness).
In the example given in the figure, overheating is 7 to.
It is usually believed that in evaporators with a direct expansion cycle, the value of the overrun should be from 5 to 8 s.
Air conditioner Servicing with jet pump (100% guarantee dust removed)
Когда величина перегрева выходит за пределы обычного диапазона температуры, это часто указывает на аномальное течение рабочего процесса.
Therefore, below we will analyze various cases of anomalous overheating of the evaporator:
Excessively large pepe (usually above 8 K) tb = TE = vapor temperature = 4 ° C
If the temperature of the point D is 18 ° C, then the overrun is 14 to.
With normal operation, refrigerated contour, the last fluid molecules evaporate at point C.
With further passage along the evaporator (section C-D), the pairs are being launched. In that case, only the CD section is filled with pairs, normal overrun is ensured (for example, 7 K).
In the event of a lack of refrigerant in the evaporator, the last fluid molecules will evaporate, for example, at point E, the length of the pipeline section, filled only in pairs, increases (in the figure this is an e-d section), which leads to a significant Neperpe. In this case, the temperature measured at point D can give a value of 18 ° C, that is, the NEPEN will be 14 to.
If overheating is too large, then the FRV hole is almost closed and passes very little liquid. The evaporator’s cold production, there is little fluid, low and the temperature difference of cooling air at the input and output is very small. The pressure of evaporation fell and at the exit from the TRV, the pipeline is covered on the outside.
Excessively small pedigre (usually below 5 s)
In the figure, the temperature at point B is equal to the temperature at point D, that is, the temperature of the gimming of 4 ° C.
(1 YEAR REVIEW) black & decker “portable air conditioner” 12000 btu
If the overrun is too low, then the TRV hole is completely open and passes a lot of liquid. Since the evaporator contains a lot of fluids, the colating production is high and the temperature difference for cooling air seems normal, however, particles of liquid may enter the compressor.This regime is extremely dangerous because they are fraught with water driver in the compressor and can cause serious damage.
In short 🙂 Now my thoughts why the condo is like it freezing, but there is no condensation. Due to the small amount of Freon, he manages to evaporate already at point E and the e-D section heats this condensate and it simply evaporates!To find out for sure, you need to measure the temperature of the return from the evaporator!
My handset is sweaty sweat! T.e. The evaporator does not sweat, and the tube sweat so its milestock 🙂 mysticism! Well, by logic, the temperature of the correctly working evaporator cannot be below 4 degrees.There are several options: 1. Independently refuel 100-150g of freon with such a thing.2. Rinse the evaporator with a foamy cleaner, t.to. There is a version that condensate is absorbed into moss on it 🙂 And it does not flow stupidly 🙂 3. Score a bolt and ride like that 🙂 because in fact, the condo freezes for all the money 🙂
What option do you choose, dear readers?
There is another way to refill in pressure and tables. Roughly speaking when the condo is turned on, then in terms of high pressure, the pressure returns and makes up from 1200 to 1500 kPa, for simplicity of understanding this is 12 and 15 atmospheres. In the region of low pressure, the pressure on the revolution drops to approximately 100-150 kPa. Now the most interesting! When the condo is turned off, the pressure in the high and low part is compared and freeze in the region of 800kp! About 8 atmospheres! But again there is a catch! This pressure depends very much on the environment! At 35 it is just about 800kp at 20 it is already 540kp.
Drainage tubes for draining condensate
Condensation through drainage tubes is discharged from the air conditioner. The pipes used in the organization of the withdrawal of the condensate from the air conditioner can be made of polyvinyl chloride or polyethylene. Products from these materials have high strength and are not amenable to water.
Conductors of air conditioners equip their goods with two types of tubes. corrugated and smooth. The latter are found only in budgetary models of air conditioners and cannot be installed without special fittings.
You can use smooth pipes to organize a drainage pipeline, but only if the air conditioner is located close to the sewer. If the connection location to the sewage system is far away, then the installation will be greatly complicated due to the use of fittings.
Humidity: The air conditioner as a dehumidifier
When using a too short drainage tube, you will hear the whistle of the wind, which is especially true for residents of high.rise buildings. In winter, from the inner block, it will significantly hang cold
Due to the high flexibility of corrugated tubes when installing a drainage pipeline, fittings will not be needed. Polymer corrugation drainage pipe for removing condensate from the outer and internal unit can be bent at any angle. The process of the device of such a pipeline will not take you a lot of effort and time.
Climatic system check valve
When connecting to the sewer system, water discharge from the air conditioner is carried out through a drainage hose. The installation of a check valve for the air conditioner will prevent the penetration of foreign odors into the apartment. He will pass the liquid and prevent the penetration of odors in the opposite direction.
A regular siphon equipped with a water plant is characterized by a U-shaped configuration. Water remains in the knee that prevents the output of sewer gases. So, during the operation of plumbing devices, there is a constant replacement of water in the water plant, so its level does not change.
Since during the operation of the air conditioner, the skodnsed water flows unevenly, the waterproof can dry out and the gases will freely penetrate the room.
The output from the situation will be the installation of a check valve for drainage split systems. Sewage drains and air will be blocked without creating obstacles to condensate. The locking mechanism is a spring membrane or a ball from ABS.
Condenser Short Cycling. 10 Possible Causes
When water enters the unit, the ball will rise, opening access to the sewer. After the liquid leaves, it will drop under his own weight, blocking the hole.
During the operation of the air conditioner, water does not drip. The air conditioner cools
If, when the air conditioner is operating, water from a drainage hose is dripping, there is no drops from the inner block, this indicates an insufficient level of freon in the system. There is a freon, its number is enough to cool the radiator to a temperature below room, but not enough to achieve performance inherent in production. split. the system cools worse.
Reducing performance can be caused by a contaminated air filter or a fan of the internal unit
Water does not flow from the air conditioner at low temperatures in the room or low air humidity. Condensate has the ability to accumulate, with clogged drainage, in the drainage pallet and hose, after filling from the inner unit, water begins to run. If you use the air conditioning for a long time, he cools, there are no drunkards on the inner block, there are no dampness on the walls, but water does not drip from the air conditioner Leave everything as it is, everything works in normal mode for you.
Condensate from the external unit does not drip
Condensate does not drip from the external unit in cooling mode, since the radiator of the external unit is hot. This should not be in cooling mode.
Condensate should only drip in the operating mode of the split system for heat during hits. At low temperatures, the external radiator is covered with a layer of snow, which reduces its performance. To solve this problem, the thawing mode is provided. which is turned on periodically, melting snow on the lamellas. Then then the water from the outer side begins to drip.
The internal block “flows”: the main reasons and their elimination
As noted, moisture that enters the pallet should be removed through the drainage system to the sewer pipe or on the street. As a rule, no pumps are required for this, everything happens by gravity, you only need to mount a drainage pipeline with a minimum slope, the value of which is a centimeter per meter. In the absence of such a slope, the water stagnates, accumulates in the system, the pallet is overwhelmed.
When removing condensate to the outside, drainage has to be equipped directly through the wall. When drilling a hole, you should focus on the slope indicated above, with a clear horizontal drilling, stagnation of water will occur.
In addition to the absence of a slope, the following may lead to the problem:
- Blockage of the drainage system. Often, the blockage is triggered by mechanical pollution, wall fragments, concrete dust formed during installation. The dense “cork” completely overlaps the fluid current;
- Moisture drainage is observed not only from the indoor unit, but also outside its limits. The reason is the gap, mechanical damage to the drainage pipe. With a large length of the system, poor.quality joints between its individual segments are likely, the lack of tightness is a common cause of leaks.
If the installation conditions do not allow to withstand the desired slope, an additional installation of a water pump is required. Its task is to form a pressure necessary for the outflow of fluid. The pump can work constantly or cyclically, by timer or as the pallet is filled. When the pump fails, of course, the accumulation of condensate will begin.
Other causes of leaks
When prolonged work leads to the course of the internal block, it is just right to talk about the following reasons:
- A wet environment is ideal for the propagation of pathogenic microflora and microfauns. Both mechanical and organic pollution that violate normal circulation can accumulate in drainage hoses. To prevent the problem, you should perform periodic cleaning. The abundance of organics indicate not only leaks, but also expressed unpleasant odors. As a rule, service intervals are indicated in the instructions for a specific device. You can clean it yourself, without calling specialists, for this it is better to purchase special chemical compounds for washing the pallet, all internal hoses, pipes and connecting pipes;
- The work of the compressor is associated with a small vibration, which is gradually able to lead to a violation of the integrity of the compounds, their depressurization. If the inspection shows their presence, you need to carry out a simple repair;
- If the air conditioner is launched in cooling mode, when the temperature of the street air fell below the zero mark, then the risk of freezing of water in the drainage system is high. Ice cork will violate normal circulation, the pallet will be crowded very quickly. If it is necessary to regularly operate climatic equipment in a similar mode, it is necessary to equip drainage with a heating element that excludes freezing;
The formation of an ice cap, hoarfrost on the heat exchanger of the room module. an unacceptable phenomenon. If this process takes place, then melting will always lead to the appearance of excessive volumes of moisture. Sometimes the ice crust is so massive that melt water simply does not fall into the pallet, begins to drain along the outer planes of the inner module. There are a lot of reasons:
- A decrease in the volume of the refrigerant, a natural decrease in its level or violation of tightness, which is why Freon is actively entering the atmosphere;
- Incorrect operation of climate technology, gross violation of the instructions;
- Increased humidity in the room. This happens, for example, with insufficient ventilation efficiency;
- Too low temperature in the cooled room, the value below what is set on the air conditioner.
The listed reasons are sometimes impossible to eliminate independently. It is more rational to contact the service center, the masters of which are well aware of the subtleties of all split systems, including the most technological versions with an abundance of electronics and additional functions. Masters will establish the real cause of the malfunction, quickly eliminate it.
It also happens that excess moisture flows from the pallet not immediately and not constantly, but with some delays. This phenomenon indicates errors made during the installation process. With a high probability, the installers incorrectly determined the length of the drainage line, a “failure” formed, a pronounced bend in which moisture gradually accumulates, and then, excess pressure, pushed out outside. For example, a leak arises every hour, half an hour or with a different interval. This situation also can not do without professional help, it will take analysis of individual components of the system, extracting pipes and hoses, adjusting their length, without which it is impossible to restore normal functionality.
When the air conditioner is working for cooling, in the inner block, water is formed. condensate. Condensate. This is a moisture located in the air, which condenses (settles) on the surface of the heat exchanger of the air conditioner, the temperature of which is below the dew point.
The dew point is the air temperature at which the steam (moisture) contained in it reaches a saturation state and begins to condensate to dew.
If the air conditioner works properly, and most importantly, the installation is performed efficiently, then the condensate is safely removed outside the room. This happens by gravity (drainage is laid with a slope), or forcibly (when using pumps, pumps, etc.P.)
What is the cause of the “leak” air conditioner in your case?
If the problem began immediately after installation (several days. a week. month). The problem most likely lies in poor.quality installation.
- The slope of the drainage pipeline is not sustained. The slope is set in the ratio of at least 1cm for every 100cm pipeline. At smaller values, the water can be collected, and in the absence of a slope, even stagnate in the pipeline, which will lead to the overflow of the drainage bath of the inner block and water leakage along the wall. Solution: Put the drainage pipeline in compliance with the required slope.
- The drainage hose was unfastened. The drainage pipeline has a joint with a bath, which can simply jump off / disintegrate. In this case, water simply flows from the air conditioner to the room. Solution: This problem is quickly eliminated by the restoration of the integrity of the drainage system.
At the end of the installation, it is important to make sure that the system is sealed and the water flows out freely. This is usually always checked by installers by spilling 1-2 liters of water through air conditioning.
If your air conditioner flowed at once, or in a short time, after installing. The guilt of all installation flaws. It is necessary to contact the installation organization and report the problem that has arisen. If the installation organization respects its customers and monitors the reputation, the deadlines for eliminating “jambs” of 1-2 working days.
Why water does not drip from the air conditioner?
Air conditioning is selected and correctly installed. You rejoice in coolness in the house and excellent work of technology. But, they take place for several weeks, and you begin to notice that condensation does not come out of the drainage tube. This is normal or it’s time to contact the service? Today we tell you why water does not drip from the air conditioner.
Professional installers or hack?
After installing the air conditioner, the master must completely check the operability of the equipment. For this, water it with water. Namely, they open the internal block of the device and pour a little liquids, about 200 ml. Next, they observe whether the water spilled out. By the way, in this way the integrity of the drainage tube is checked. These actions must be performed under the customer so that he has no doubt about the operability of the air conditioner. If such a check was not carried out, then perhaps the installation was carried out by the not professionals performed.
If there is no doubt about the functioning of the technique, then let’s analyze whether the water should come out of the drainage tube at all? Yes, it should. But only under certain conditions. Condensate is formed at high humidity in the room and temperature below 18 g. Either there should be a significant difference between the temperature in the room and the indicators of the thermometer on the street.
If the room is set in the air cooling mode to 20–25 gr., then very little condensation is formed. He may not go to the end of the drainage tube. At the same time, keep in mind that it is corrugated.
If condensation does not come out of the pipe, and the air conditioner is working properly, then there is no reason for concern. Doubts overcome? Follow the technique. To do this, set a low temperature, about 30 minutes. Water should flow.
The experiment failed? So the filter or drainage tube is closed. Rinse the filter under water. You can check the contamination of the drainage tube using ordinary water. To do this, pour carefully a liter of liquid into the evaporator. If it does not leak, you will have to clean the phone. Otherwise, the condensate will begin to drip into the room.
