Heavy air and misted windows can be considered a rather unpleasant problem in the apartment, but owners of plastic models face it. These inconveniences are the result of the main advantage of double-glazed windows with such a design, it is expressed in tightness. This indicates that plastic windows do not provide natural ventilation, do not have the ability to breathe, like natural wood counterparts.
As a result, the level of humidity rises, it accumulates, the percentage of carbon dioxide increases, a person begins to feel stuffy. Fresh air does not enter the room, as a result, a person's performance decreases, he experiences drowsiness, in some cases even an allergy appears.
The result of airing - condensate
It is worth mentioning that ventilation does not solve the problem described above, because the advantages of plastic windows in this case are simply lost. As a result, heat loss increases, noise insulation decreases, unpleasant odors, carbon monoxide and dust penetrate into the premises. Dirt accumulateson the windowsill and floor.
Some manufacturers today offer for sale an additional accessory called a slot microventilator. It is located on the swing-out doors.
Problem Solving
If you turn the handle at an angle of 45 °, the sash opens a few millimeters, this allows you to create passive air exchange and a draft. However, the problem with tightness and heat saving remains. Fresh air will effectively enter the room if the house ventilation works well, and the rooms have access to ventilation ducts. The solution to this problem is moisture-sensitive ventilation systems called automatic valves, which will be discussed below.
Valve principle
Aereco is a valve that appeared in 1983 in Paris. It has been designed to adjust the flow of outside air according to indoor humidity levels. Thanks to the presence of such a system, there is no need for ventilation, while maintaining the noise and heat insulation properties of the window.
If there is a large enough crowd inside, the sensor will start to work more actively, otherwise the valve will close. This indicates that the device allows you to get the volume of dry and cold air that is needed. Exhaled carbon dioxide and cooking increase the humidity in the home, this creates suitable conditions for the creation of pathogenic microflora."Aereko" is a valve that provides a constant supply of air from the outside, which creates comfortable conditions for a person, preventing oxygen starvation and respiratory diseases.
Adjustment of humidity of air excludes formation of a mold on walls and slopes, protecting from condensation. The Aereko window valve is a small overlay that has an attractive appearance, it does not take up much space and fits into any interior. On sale you can find such valves in several colors, among them:
- tick;
- grey;
- white;
- beech.
This equipment is quite easy to maintain, during the year it will only be necessary to remove dust from the surface of the body with a vacuum cleaner with a soft nozzle a few times. And the installation of the valve is quite simple, installation will take about an hour. The structure is located in the window sash or in the wall. A visor, controllers and grille are installed outside, the latter of which protects the structure from insects and dust.
Design features
On sale you can find windows in which the described valves are built in under factory conditions, so the consumer does not have to deal with these manipulations on his own. The operation of the sensor is based on the principle of the physical law of expansion of materials.
When humidity increases, solid structures expand, while when they decrease, they contract. The composition contains moisture-sensitive polyamide plates, the number of which issystem can vary from 8 to 16. It is they who react to the set humidity temperature, affecting the mechanism for closing or opening the damper, while no power is required.
What else you need to know about how it works
"Aereco" - a valve that has a moisture-sensitive tape indoors. When the level of humid air in the room increases, the tape lengthens, the damper opens, and dry air from the street enters, while carbon dioxide is forced out, it exits through the kitchen exhaust, which should not be blocked during operation. As the degree of humidity inside the room increases, the dampers open more and more.
"Aereko" is a valve that has a unique design, it is not exposed to the air flow from the outside, so the level of humidity in the room is determined as accurately as possible. When the air humidity drops, the valve closes automatically, and during bad weather or strong winds, the modes can be switched independently.
Aereco valve classification
The device described above is classified into two types, among them:
- EMM;
- EHA2.
The first option is a classic design that is great for small spaces. She has a thin body, and the air from the outside enters the inside obliquely or vertically, which will depend on the position of the window. The second type of valve has a stylish design anda fairly high degree of protection from outside noise. This Aereko supply valve is directed to the ceiling, thanks to which the incoming air is heated, as a result, it is possible to achieve maximum comfort in the apartment.
The device can additionally be equipped with an acoustic prefix. In some cases, the installation of the valve is not possible, this indicates the possibility of using an alternative device - EHT, fixed to the wall. This design has an attractive appearance and is quite easy to install using a special cutter. From external noise, this valve protects quite effectively.
Installation recommendations
Aereko valves are installed according to a certain technology. There is no need to remove windows for this. To begin with, the master will have to mark the place where the device will be located. In this case, it is important to pay attention to the presence of other window fittings that may interfere with installation. The inlet valve bar is reinforced with self-tapping screws.
On the porch of the frame, it is necessary to mark the grooves, which can also be located on the sashes. When the Aereko ventilation valve is installed, the next step is to remove the bar and cut the holes, for this you should use an electric jigsaw or drill. First, holes are made in the wings, and at the next stage - in the frame. Next, you can re-install the bar and fix the window valve on the latches.
Installation reviews
According to buyers, the installation of the supply valve may be accompanied by some costs. For example, the cost of the described device of the EMM series in a complete set is 150 euros. The system provides for:
- valve;
- mosquito net;
- acoustic visor.
According to users, although these valves are unique, they have one drawback, which is expressed in the possibility of high-quality installation only in the factory. The Aereko valve, reviews of which should help you make the right choice, is installed at the factory after two channels are cut in the upper part of the window in the sash and frame profile. A special milling machine is used for this.
If you use the services of specialists to install the valve on the finished window, the master will fix a metal template on the sashes and frames, in some cases these works are carried out "by eye". With the help of an electric drill, experts make several through holes, while dirt and chips will form. At the next stage, holes are cut into a kind of through channel, the edges are processed with a file. On this, we can assume that the Aereco EMM valve is installed. The resulting frame edges can be closed with parts of the inlet valve. As a result, according to buyers, you may encounter a problem expressed in a damaged window.
Specifications
Aereco valve, the characteristics of which you should consider before purchasing the product, is offered for sale inseveral models, among them:
- EMM 5-35;
- EMM 11-35;
- EMF 35.
In the first two cases, there is a function of hygroregulation, as for the presence of the option of operating mode switch, it is in the first and last versions. It is also important to pay attention to the air flow at a pressure of 10 Pa. In the first case, this parameter can vary from 5 to 35 m3/h, in the second - from 11 to 35, and in the third it is 35 m3 /h. The maximum opening area in all three cases is 4000 mm2.
