"AERECO" (valve): the principle of operation

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 a consequence of the main advantage of double-glazed windows with this design, it is expressed in tightness. This indicates that the plastic windows do not provide natural ventilation, do not have the ability to breathe like analogues made from natural wood.

As a result, the level of humidity rises, it accumulates, the percentage of carbon dioxide increases, a person begins to feel stifling. Fresh air does not enter the room, as a result of this, the working capacity of a person decreases, it experiences drowsiness, in some cases there is even an allergy.

The result of ventilation is condensate

It is worth mentioning that airing 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, odors, carbon monoxide and dust penetrate into the premises. Dirt accumulates on the windowsill and floor.

Some manufacturers today offer an additional accessory for sale, which is called a slot micro-ventilator. It is located on the turn-flaps.

Solution

If you rotate the handle by an angle of 45 °, then the door opens several millimeters, this allows you to create passive air exchange and draft. However, the problem with tightness and heat savings remains. Fresh air will effectively flow into the room if indoor ventilation works well, and rooms have access to ventilation ducts. The solution to this problem is the moisture-sensitive ventilation systems, which are called automatic valves, they will be discussed below.

The principle of the valve

"AERECO" is a valve that appeared in 1983 in Paris. It was designed to regulate the flow of external air, which depends on the level of humidity inside the premises. Due to the presence of such a system, there is no need for ventilation, while the noise and heat-insulating properties of the window remain.

If there is a large enough crowd of people inside, the sensor will start to work more actively, otherwise the valve will close. This indicates that the device allows you to get a volume of dry and cold air, which is necessary. Exhaled carbon dioxide and cooking increase the humidity in the dwelling, this creates suitable conditions for creating a pathogenic microflora. "AERECO" 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.

Adjusting the humidity of the air eliminates the formation of mold on walls and slopes, protecting from condensation. Window window "AERECO" is a small overlay, which 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:

• teak;
• gray;
• white;
• beech.

This equipment is quite easy to maintain, during the year it will only be necessary to remove the dust from the surface of the case a few times using a vacuum cleaner with a soft nozzle. And the installation of the valve is quite simple, installation will take about an hour. The structure is located in the sash of the window or in the wall. Outside, a visor, controllers and grill are installed, the last of which protects the structure from insects and dust.

Design features

On sale it is possible to meet windows in which in the conditions of a factory the described valves are built in, therefore the consumer does not have to deal with these manipulations independently. The work of the sensor is based on the principle of the physical law of expansion of materials.

With increasing humidity, solid structures expand, while at a decrease - they narrow. The composition contains moisture sensitive polyamide plates, the number of which in the system can vary from 8 to 16. The specified humidity temperature is reacted by them, influencing the mechanism of closing or opening the damper, with no power required.

What else is necessary to know about the principle of work

"AERECO" is a valve that has a moisture-sensitive tape inside the room. When the level of moist air in the room increases, the tape lengthens, the flap opens, and the dry air from the street comes in, while the carbon dioxide is expelled, it exits through the kitchen exhaust hood, which should not be blocked during operation. With an increase in the degree of humidity inside the room, the flaps open more and more.

"AERECO" is a valve that has a unique design, it is not exposed to air flow from outside, so the humidity level in the room is determined as accurately as possible. When the humidity drops, the valve closes automatically, and during bad weather or strong winds, the modes can be switched on their own.

Classification of valves "AERECO"

The device described above is classified into two types, among them:

• EMM;
• ENA2.

The first option is a classic design, which is great for small rooms. It has a thin body, and the air outside comes in obliquely or vertically, which will depend on the position of the window. The second version of the valve has a stylish design and a rather high degree of protection from noise outside. This supply valve "AERECO" is directed to the ceiling, thanks to this heating of the incoming air is ensured, 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 likelihood of using an alternative device - EHT, fixed to the wall. This design has an attractive appearance and can be easily installed with a special cutter. From external noise, this valve protects quite efficiently.

Installation Recommendations

Installation of valves "AERECO" is carried out by a certain technology. For this, there is no need to dismantle the windows . 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 can interfere with the installation. The plenum of the supply valve is strengthened by means of self-tapping screws.

On the porch of the frame, it is necessary to mark the grooves, which may also be on the doors. When the "AERECO" ventilation valve is installed, the next step is to remove the bar and drill holes, using an electric jigsaw or drill. First, holes are made in the sashes, and at the next stage - in the frame. Then you can re-install the bar and fix the window valve to the latches.

Reviews about the installation

According to the buyers, installation of the supply valve can be accompanied by some expenses. For example, the cost of the described device series EMM in full version is 150 euros. The system provides for:

• The valve;
• Mosquito netting;
• Acoustic visor.

According to users, these valves are unique, but they have one drawback, which is expressed in the possibility of a quality installation only in the factory. Valve "AERECO", reviews about which should help you make the right choice, is set in the plant conditions after two channels in the top and window sections are cut in the top part of the window. For this, a special milling machine is used.

If you use the services of specialists installing the valve on the finished window, the wizard will fix the metal template on the sash and frame, in some cases, these works are carried out "by eye". With the help of an electric drill, specialists make several through holes, while creating dirt and shavings. In the next stage, the holes are cut into the like of a through channel, the edges are processed by a file. On this, we can assume that the valve "AERECO" EMM is installed. The resulting edges of the frame can be closed with parts of the supply valve. In the end, according to customers, you can face the problem, expressed in a corrupted window.

Specifications

Valve "AERECO", the characteristics of which you should consider before purchasing the 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 function of hygro-regulation, as for the presence of the option of the mode switch, it is in the first and last variants. 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 is equal to 35 m ³ / h. The maximum opening area in all three cases is 4000 mm ² .
