Heavy air and fogged windows can be considered a rather unpleasant problem in the apartment, but owners of plastic models are faced with it. These inconveniences become a consequence of the main advantage of double-glazed windows with this design, it is expressed in tightness. This indicates that plastic windows do not provide natural ventilation, do not have the ability to breathe, like analogs made of natural wood.
As a result, the humidity level 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 of which the person's working capacity decreases, he experiences drowsiness, in some cases even an allergy appears.
Result of ventilation - 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 losses increase, noise insulation is reduced, unpleasant odors, carbon monoxide and dust penetrate inside the premises. Dirt accumulates on the windowsill and floor.
Some manufacturers today offer for sale an additional accessory called a slotted micro-ventilator. It is located on the flap.
Solution
If you turn the handle at an angle of 45 °, then the sash opens a few millimeters, this allows you to create a passive air exchange and draft. However, the problem with tightness and heat conservation 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, which are called automatic valves, which will be discussed below.
Valve operating principle
Aereco is a valve that appeared in 1983 in Paris. It was designed to control the flow of external air, which depends on the humidity level in the rooms. Thanks to the presence of such a system, there is no need for ventilation, while the noise and heat insulation properties of the window are preserved.
If there is a sufficiently large crowd of people inside, the sensor will begin to work more actively, otherwise the valve will close. This indicates that the device allows you to get such a volume of dry and cold air, which is necessary. Exhaled carbon dioxide and cooking increase the humidity in the home, this creates suitable conditions for creating a pathogenic microflora. "Aereco" is a valve that provides a constant flow of air from the outside, which creates comfortable conditions for a person, preventing oxygen starvation and respiratory tract diseases.
Humidity control eliminates the formation of mold on walls and slopes, protecting against condensation. The Aereco 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:
This equipment is quite easy to maintain, during the year it will only be necessary to remove dust from the surface of the case only several times with a vacuum cleaner with a soft nozzle. And the installation of the valve is quite simple, the installation will take about an hour. The design is located in the sash of the window or in the wall. Outside, a visor, controllers and grille are installed, the last of which protects the structure from insects and dust.
Design Features
On sale you can find windows into which the described valves are built in in a factory, so the consumer will not have to deal with these manipulations on their own. The operation of the sensor is based on the principle of the physical law of expansion of materials.
With increasing humidity, the solid structures expand, while with decreasing, they narrow. The composition includes moisture-sensitive plates made of polyamide, the number of which in the system can vary from 8 to 16. They are the ones who react to a given humidity temperature, affecting the mechanism for closing or opening the damper, and no power supply is required.
What else you need to know about how it works
"Aereco" is 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 displaced, it exits through the kitchen exhaust opening, which should not be blocked during operation. With increasing humidity inside the room, the dampers open more and more.
"Aereko" is a valve that has a unique design, it is not exposed to external air flow, so the humidity level in the room is determined as accurately as possible. When air humidity decreases, the valve closes automatically, and during bad weather or strong winds, the modes can be switched independently.
Classification of Aereco Valves
The device described above is classified according to two varieties, among them:
The first option is a classic design, which is great for small rooms. She has a thin body, and the air outside comes in obliquely or vertically, which will depend on the position of the window. The second type of valve has a stylish design and a fairly high degree of protection against noise from the outside. This "Aereco" supply valve is directed to the ceiling, due to this, the incoming air is heated, as a result it is possible to achieve maximum comfort in the apartment.
The device can optionally be equipped with an acoustic set-top box. In some cases, the installation of the valve is not possible, this indicates the likelihood 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. This valve protects from external noise quite effectively.
Installation Recommendations
Installation of Aereco valves is carried out according to a certain technology. There is no need to dismantle windows for this. First, the master will have to mark the place where the device will be located. It is important to pay attention to the presence of other window fittings, which may interfere with installation. The supply valve strip is fixed with self-tapping screws.
On the porch of the frame, it is necessary to mark the grooves, which can also be on the wings. When the Areco ventilation valve is installed, the next step is to remove the bar and cut holes, for this you should use an electric jigsaw or drill. First, holes are made in the leaves, and in the next step, in the frame. Next, you can re-install the bar and fix the window valve on the latches.
Installation Reviews
According to customers, the installation of a supply valve may be associated with some costs. For example, the cost of the described device in the EMM series in a complete set is 150 euros. The system provides for:
- Valve
- mosquito net;
- acoustic visor.
According to users, these valves, although unique, have one drawback, which is expressed in the possibility of high-quality installation only in the factory. The Areco valve, reviews of which should help you make the right choice, is installed in the factory after two channels in the sash and frame profile are cut in the upper part of the window. For this, a special milling machine is used.
If you use the services of specialists in installing the valve on a finished window, the master will fix the metal template on the sash and frame, in some cases these works are carried out “by eye”. Using an electric drill, experts make several through holes, and dirt and chips will form. At the next stage, the holes are cut into a kind of through channel, the edges are filed. On this, it can be considered that the “Aerereco” EMM valve is installed. The resulting frame edges can be closed with parts of the supply 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 a product, is offered for sale in several models, among them:
- EMM 5-35;
- EMM 11-35;
- EMF 35.
In the first two cases, there is a hygroregulation function, as for the availability of the option of the mode switch, that is, in the first and last options. It is important to pay attention also to the air flow at a pressure of 10 Pa. In the first case, this parameter can vary from 5 to 35 m 3 / h, in the second from 11 to 35, and in the third it is 35 m 3 / h. The maximum opening area in all three cases is 4000 mm 2 .
