Split system condensate drips from the indoor unit

The first reason. This is the incorrect operation of the electric conditioner. The technical product includes detailed instructions for use with the instructions of the developers, following which in the work of the air conditioner there will be serious violations will not. Mistake. This non-compliance with the temperature regime recommended by the manufacturer. The ratio of temperatures indoors and on the street:

In the summer period, the temperature difference is 5-6 degrees.

When installing on heating, the temperature of heating 30 and above degrees is placed on a short period of time.

What if dripping conditioner?First of all you need to get to the drainage.

When deviating from the norm, the end result. Technique does not cope, and begins to generate an excessive amount of condensate.

The second reason. Close of drainage pipe. In the hose accumulate garbage, dust and insects, provoking water to flow into the room. At the bottom of the device, the pallet in which condensate flows. From the pallet, the liquid merges through the drainage tube to the street or in the sewer. When casting condensate does not flow, but accumulates in the bath, and water from the air conditioner flows into the apartment.

Third reason. These are errors when installing and installing. If, for example, the device is not installed at the level, the pallet is also at an angle. Even with the smallest slope of water that flows into the drainage hose under the power of gravity, begins to drip past the bath, or, due to tilt, drain from the indoor unit on the floor of the room or on the wall. Installation errors:

thermal insulation of wires with freon is absent;

Incorrect length, angle of inclination of the drainage route;

The internal unit is not attached by level;

The amount of freon or type is not suitable for the selected model.

The reason is the fourth. Freon leakage. Freons are used as refrigerants. Fluorine-containing hydrocarbon compounds. Freon absorbs heat during evaporation and highlights in condensate, and condensate is already flowing through the drainage system. When leucing freon or lack of refrigerant, an internal block evaporator is icing, and water flows from air conditioning.

Causes of occurrence

Physical essence of the phenomenon is quite simple: condensate always appears when cold and heated air are found among themselves. Only securingly dividing them and not allowing you to enter into “close contacts of the wet”, you can achieve perfect dryness. Experienced builders know how to achieve this, therefore it is not worth saving on their services.

The technical reasons why the dew in the attic is formed as follows:

  • Low quality roof thermal insulation;
  • heat protection weakness;
  • lack of ventilation under the roof itself;
  • Errors when laying protection against steam or water;
  • Bad installation of windows, slopes and doors on the roof.

The common between them is that all this. the consequences of technological errors, flaws or improper savings on materials. Attempts to save the funds in this way there is a serious mistake, since eliminating the condensed condensate is much more complicated than to avoid its occurrence. Cheap film seems to and performs the tasks of waterproofing, but impenetrable surfaces will prevent condensate to evaporate. He can only fill the insulation or leak onto the surface of the finishing material.

How the drainage system of the air conditioner is arranged

During the operation of the air conditioner in cooling mode, the evaporator of the room unit of the Split system is cold, about 0 ° C. Air passing through it is rapidly cooled to temperature 2. 8 ° C, water steam condenses and flows into the structure provided by the design. From the pallet, the water Self-drainage hose is given to the street, into the sewer, the drainage system and T.D. To do this, the drainage hose must be laid with a slope in the direction of the drain, if for any reason it is impossible, then special drainage pumps are used to remove condensate.

Drainage pump air conditioner benefits and disadvantages

The drainage pump of the air conditioner consists of two main parts. the pump housing and the float chamber. Connecting to the 220V network is carried out on the terminals of the split-system unit itself, it is not required to bring a separate power cable.

The float chamber is located in a structural cavity inside the air conditioner unit and connects to the drainage hose. In the wall types of air conditioners, there is not enough space to accommodate the housing of the pump itself inside the block, it is taken out or for it a special deepening in the wall, as in the photo.

If there is an opportunity to pave a drain hose with a bias, whatever efforts it requires, then it will work better. Apply pumps only in cases where there is no possibility to remove drainage gravity. This is connected with some disadvantages.

  • First, the drainage pump of the air conditioner is an additional cost of its acquisition and installation, the average cost with the installation of a qualitative pump of such brands, as “Sauermann” (France) or “Aspen” (England) will cost about 6,000
  • Secondly, the pump may fail to entail costs for its acquisition and replacement.
  • Thirdly, the work of the pump is accompanied by not long, but additional noise (buzzing), which annoys and leads to the rabies of particularly sensitive users, especially at night.

The advantage can be attributed to the condition allows you to select any place to accommodate the room unit of the air conditioner and remove the condensate from it forcibly, and, when the condensate is pumping, the sewage will not require a special siphon or hydraulication to prevent the appearance of unpleasant sewer odors of human life.

How the drainage pump is working

All drainage pumps for air conditioners have the property of dry suction, it means that the pump starts to dry and does not require filling with water. However, the long-term operation of the pump on the dry will result in its breakdown, since the pump in the process of operation is cooled by the pumped liquid.

The principle of work is as follows. Condensate from the plot of the split-system unit flows down the drainage hose in the float chamber. As it filling the float floats and closes the contacts, thereby launching the pump motor. Due to the small volume of the float chamber, the pump turns on only for a few seconds, the float is lowered, blur contacts, the pump turns off.

Where in air conditioner water and why she starts to drip

The main function of the air conditioner. air cooling. With this task, a number of mechanisms in the internal and outer block are coping with. In the process of work on the evaporator (cooling element), condensate is formed, which should be stroke into a special container, and then on the drainage tube is removed on the street.

Due to different problems, the condensate formed on the evaporator can drip past the capacity, leaving drums on the walls next to the block, fall into the fan or flow from the container without passing through the drainage track. Before determining the course of repair work, you need to find out the exact cause of the fault.

How much condensate allocate air conditioning

The amount of condensate formed is determined by the parameter of the power of the device for such a formula: 1kW of cooling capacity. 0.5-0.8 l / h condensate. That is, if the house has a split-system for 3 kW, the average condensate will be 1.5-2.4 l / h.

Why water in the apartment flows from the air conditioner and what to do in this case

You are familiar with the air conditioner, the cooling process began, but after some time you found that the water in the apartment is dripping out of the indoor unit. Liquid can flow:

  • directly from the inner block into the room,
  • Through the blinds together with the flow of cooled air, as if the air conditioner “splashes” or “spits” with water,
  • on the wall on which the block is installed.

At the same time, as a rule, the air conditioner does not immediately after switching on, but after some time. in 20-40 minutes. The intensity of the flood directly depends on the setting temperature of the cooling: the greater the drop between the temperature in the room and the specified split system, the more power will be.

Where in air conditioner water and why she drips into the room

The operation of split systems is based on cutting air cooling. Such a change in temperature leads to the formation of condensate on the cooling element of the air conditioner. the evaporator located in the internal block. Normally water flows from the evaporator to a special bath, and then on the drainage track is removed to the street or in the sewer. Most often, the drainage tube is removed on the street, from where condensate dripping.

The air conditioner leakage is usually caused by any problem, and technically occurs in one of the following ways:

  • Water does not leave the bath for the drain track. For example, due to the drainage. As the capacitance overflows for condensate, water flows from the Split system to the room.
  • Condensate dripping past the bath. For example, if it shifted.
  • Water hits the fan, and the air conditioner “spits” with water. For example, this happens when the evaporator is frosting due to too low condensation temperature.

Naturally, the split-systems in the room is not a regular version of the technique. In some cases, this behavior of the air conditioner is associated with an incorrect installation, sometimes. with a disruptive operation, but more often. with breakdowns. Below we will look at the main reasons for which water comes from the air conditioner to the room.

User errors in which air conditioner flows

When choosing an air conditioner and its further operation, it is extremely important to comply with the recommendations of the manufacturers by the temperature regime: both on the street and indoors. Violation of the norms of operation leads to incorrect work, frost and leaks, both internal and external block.

Case from practice! Application from a flower shop. The air conditioner with a capacity of 7000 W does not work: an external block in ice, from the inner. water drips. Room area small. 6 m. Ruffy. On the street the temperature is about 0 ° C, indoors 20 ° C. Installation disorders not found. What could be the reason? In the instruction manual, we read: when cooled, the temperature on the street should be 18. 43 s, indoors 21. 32 s. Thus, the cause of the problem is in violation of operating conditions, as well as initially incorrectly choosing a split-system model for customer needs.

Why water drips from the inner block of the new air conditioner

If you notice that the air conditioner installed recently mounted in the room, in the overwhelming case, the reason lies in the installation errors. Normally condensate from the evaporator flows into the bath, then it is removed by the drainage canal to the street or in the sewer. If the highway is simple. water is due to gravity under the action of gravity. In the tracks with a complex configuration (big length, height difference and t.D.) A drain pump is set for forced water removal.

When installing the split system, the following errors can be made:

  • Incorrect angle of inclination of the drainage route. The drainage canal was carried out under an insufficient angle: the water does not break down the samoter as it should be, but instead poured out of the crowded bath in the room.
  • The internal block hangs not exactly. If the air conditioner is not installed in terms of level, the bath is at an angle. In this case, condensate can flow past the bath or drip into it, but due to the inclination to flow through the edge into the apartment.
  • Thermal insulation of freon pipelines. Tubes connecting the external and internal block must be isolated properly. Otherwise, condensate will be formed on them. In places where the tubes enter the internal unit of the resulting moisture will be drained along the wall or drip from the inner block.
  • Incorrect air conditioning refueling (not the type of freon, not the amount) lead to the fact that the internal block is frozen. Floabe pushes, water flows past the bath.
  • Chalks on the tubes with a refrigerant. Sometimes “handicraft” masters are closed by tubes conducted by Freon. Because of this, the cross section is reduced, as a result. pressure changes in the system, formed on the evaporator. Ottay, she flows into the room.
  • The crane on the thick tube of the external block is open. Because of this, in the system insufficient refrigerant pressure. As a result. frost and flow.
  • Invalid Long Route for Freon. If the refrigerant route is more or less recommended by the manufacturer, Freon boils before or later than the evaporator. As a result, the tubes are covered with ice, condensate is formed, which drips into the room.

According to the experience of the “Rembyttech” masters, an incorrect installation is one of the frequent reasons for the service center. Unfortunately, most of the installers from companies selling split-systems do not have sufficient qualifications and knowledge of air conditioning devices.

Such “Masters” are often offering decisions that violate the installation guide. as a result, it leads to breakdowns and incorrect work of technology. You can avoid trouble, trusting the installation of the air conditioner professionals, for example, from Rembyttech.

Our experts will design and mounted even a complex air conditioning system without errors and with a guarantee.

The most common faults in which the internal block in the Split system flows

If your air conditioner is no longer new, it worked properly, but suddenly the water began to drip in the room. probably there was a breakdown. Which one. will help determine the table below.

Installers with two left hands

Condensate discharge problems can begin shortly after installation of the air conditioner. In 99% of cases, this due to unprofessional (in some cases drunk) installers.

The fact is that the drainage tube must go under the tilt down. Sometimes when installing in the wall make a hole, which goes parallel to the ground, or at all directed up. In this case, according to the law of gravity, the moisture will not be able to drop and accumulates in the tray.

Identify the problem is easy. just look at the entrance and yield of drainage from the wall.

Output two. either punch a new hole, or outweigh the air conditioner higher. But it is best to call installers. They are simply obliged to fix their mistake.

If you put air conditioning yourself, you will have to arm a peuorator and choose. Naturally, it will be easier to break a new hole. His input must begin there, where and the old one, but the channel must be sent down.

How to remove condensate from air conditioning

After the above information, the question arises how to allocate the condensate from the air conditioner. Frequently used and profitable method. It to bring the drain pipe to the street by drilling a small hole in the wall. The main advantage is simplicity. made a hole, stretched the hose and everything works. But there is a negative side, it lies in the effect of “raindrops”, which will fall on the windowsill and deliver a lot of inconvenience to neighbors. Also, the disadvantages include the aesthetic side. As if practical was not given this way, not everyone likes hanging from the apartment pipe; on a bare wall.

It will be much better to use condensate removal in the sewer.

This option does not have any minuses. Air conditioner waste merged into the system intended for this. It can be like a common sewer channel, and a specially installed network of pipelines. The removal of all effluents will occur without your help due to the tilt of the pipes.

But there are also its subtlety to implement such a condensate drain system from air conditioning:

  • In order for the vile smell from the drain into the room, it is necessary to install the waterproofing. this is the curve part of the drainage tube in the form of the letter S. The work of such a shutter is similar to the work of the siphon. it creates a barrier for the smells that come from below.
  • If the air conditioner is idle for a long time, the hydraulication can dry and the air leaves from it will begin to give by sewage. So that this is not, just once in 5-7 days pour a few liters of water into the drain.
  • When using an option with samoter, it is necessary to accurately calculate the minimum diameter and the slope of the system so that all the air conditioner waste can smooth over it.

Usually manufacturers make a detailed scheme that facilitates the installation process.

Drainage tubes for air conditioners

Drainage tubes from air conditioners refer to the discharge system and the market are represented by two positions:

The first option is most often used if the length of the flow is small, in other cases corrugated systems are used. At the same time, the second species has another huge advantage. this is the excellent flexibility of the drain hose, due to which during the installation there is no need to use additional fasteners as necessary when working with smooth pipes.

Condensate Reference System Installation

Despite the difficult descriptions of actions, in practice, the discharge process is extremely simple and requires you only attentiveness:

  • The first thing to do is remove the air conditioner fasteners that are below.
  • In the lower part under the fan there will be a small container for the collection of excess condensate. With the side of it, it can be seen nozzle, to it with a clamp and attach the drainage pipe of the outlet.
  • Next back to assemble and install the air conditioner in place. But it is important that the tube passes through the hole in the lateral part of the air conditioner.

Now you need to withdraw the accounted earlier hose in the sewer or to the street. If the hose is assigned correctly, you will see the first drops that come out of the pipe.

Flowing conditioner

Leonid Sergeev: From the inner unit of the air conditioner occasionally water flows on the wall, we can not solve this issue when we call customer equipment professionals, then there are no leaks In short, wonders with our air conditioning. Tell me how we finally deal with the problem of the split system

Eyre Full: Your problem is quite popular and often lies not only as an air conditioner installation. The air conditioner leak has several reasons, one of which is primarily the correct installation of the split system.

If we consider everything in order, then it is worth starting with the simplest. this is the pressure drop on the street (where the drainage canal is derived) and indoors.

How much do you understand, after the rain (thunderstorms) on the street, atmospheric pressure changes sharply, while indoors with closed windows it remains at the same level, so air traffic jams are formed in the drainage channel.

In this regard, the drainage pallet of the indoor unit is overflowed and the air conditioner flows through the edge.

It would seem here immediately everything becomes clear, but the question is being custled:. Why, because the Water Pole must be sold in height. (In case the condensate hose is displayed on the outdoor panel paw). But in this case there is your explanation.

During the operation of the indoor unit of the air conditioner, the ventilation drum rotates, thereby moving the air (air masses) through the coarse filter, the evaporator and throws away at the location of the blinds.

You should not forget that at the place of active rotation of the ventilating drum of the indoor unit of the air conditioner is a drainage bath with a hole for drainage drainage.

Therefore, when moving the air mass, at the same time, air from the street is also fond of the drain hole, and water flowing from the evaporator (radiator in cooling mode) also seeks to drainage.

Based on this pressure difference scheme and response air inside the indoor unit. air conditioning flows through the edge.

The following situation at which the air conditioner flows is also somewhat banal and from part it is similar to the above described, but in this case the cause is the contaminated filter of rough cleaning of the inner block of the split system (grid).

Moving air through the internal unit (described above) with contaminated filters is greatly difficult due to poor air passage through the dust layer (like a thin felt), therefore the actively rotating ventilation drum sucks the air through the drainage hole (or raises the water residues closer to the drain bath) and The air conditioner evaporator is practically not blown. With a bad blowing of the evaporator of the indoor unit, the radiator begins to freeze, the temperature sensor gives the command to the air conditioner to turn off the compressor and becomes defrosting. Next, the frozen evaporator Ottayivaya overwhelms the drain bath of the inner block of the split system and the air conditioner flows through the edge.

Now it’s time to consider situations of poor-quality installation of the air conditioner, from which not only internal blocks of split systems cry, but also our favorite consumers who have decided to save

As a rule, the first error is the wrong laying of the drainage hose, the lack of slope, allowing wave-like bends, hoping that the water post will produce and no air traffic jams are formed, but comparing the situations described above, you can already understand that this is not the case. as a result, the air conditioner flows.

The second error is the incorrectly used consumables, instead of a specialized hose use electrofra, which are scattered after some time. as a result, air conditioner flows, wet walls and t.D.

The most simple error, this is when the insulation is not used with the insulation of the tube in the connection site under the inner block of the split system and under the influence of the temperature of the freonotrass and outdoor air, condensate is formed. as a result, air conditioner flows.

The latter situation is not frequent, but quite common: when the condensate tube is output, it is completely forgotten about the knee installation (siphon), which prevents the penetration of the smell from the sewage and ensures easy condensate disposal, otherwise the air conditioner flows and the disgusting smell can be supplied to the room Toilet.
