Fresh air valve in the wall: the principle of action, selection and installation

Adequate supply of fresh air in residential building - a prerequisite for the implementation of sanitary regulations requirements. Ensure a healthy state of the atmosphere can be a variety of ways. If you set the air inlet in the wall - the problem will be resolved quickly, without extra costs.

Why the need for air inlet in the wall

The widespread use of such specialized equipment began after the mass installation plastic windows. New designs of blocks with quality seals We create effective protection against dust, noise and other negative external influences. However, along with improved insulation characteristics decreased the amount of fresh air.

increased humidity and the normal temperature in the living room - a good environment for microorganisms. Mold and mildew can build up under the wallpaperIn other hidden places. Therefore it is not always possible to notice the negative processes. Later, after the visible manifestation, we have to spend a lot of money to repair, replacement of defective finishing materials. Are destroyed quality wood products, Expensive fabrics. Biological contamination provoke short circuits in electronic equipment.

It should be emphasized that certain kinds of microorganisms is extremely dangerous to humans, domestic animals. They provoke allergic reactions, are the cause of serious diseases.

With a lack of ventilation there is a lack of oxygen, deteriorating state of health, the physiological condition. This abnormal condition of the room atmosphere is not derived naturally occurring contaminants, odors. We should not forget that in the older building and furniture technologies used formaldehyde, and other harmful substances, chemical compounds.

Important! To operate the gas stove, boiler must ensure a flow of fresh air.

Operating principle

With this figure easier to understand the functioning of the system.

Fresh air enters the room through a special device, which is set within the external walls of living rooms. Pay attention to the exact place of their installation on heating radiators. This simple technique allows to "automatically" to heat the air in the winter season.

But without the "output" so the system will not work. Exhaust air organized in the kitchen, bathrooms. It is here that requires a large amount of dirt and humidity.

It is necessary to ensure the free passage of the air flow on the desired path. It is necessary to remove the obstacles to their finding. Typically, they are created door blocks.

The following list shows the criteria to be met by a good supply valve in the wall:

• He should have sufficient capacity to not have to use additional techniques to increase the efficiency of ventilation.
• It needs to be protected against the ingress of premises insects, rodents.
• Useful mechanical filter that prevents dust intake.
• Desirably, the changes made in the building structure not worsened heat- and soundproofing.
• When choosing the right product is checked by the complexity of installation, affordability, durability, the need for and frequency of maintenance.
• In any case, the positive assessments deserves comparative simplicity of the product, indirectly confirms the high reliability.
• If there are no embarrassing adjustment will not appear the extra load on the user during operation.

It is difficult to argue that the high-quality micro-climate is very important for health. But when it comes to the security of air in the house, you need to learn the theory. It helps to learn about the different Schemes private house ventilation with his own hands a special publication dedicated portal for engineering services at home Aquatic-Home.ru.

Design

the above requirements corresponds to a typical construction of the supply valve in the wall.

The individual structural elements perform the following functions:

• The grille (9) mounted on the outside wall. It is made from aluminum. This metal is strong enough to prevent penetration of small animals. He does not rust like steel, so over time the wall will not appear unsightly streaks of rust. Cu the inside fixed input lattice mesh of polymeric fibers - protection against mosquitoes.
• The part of the channel (8) mounted heat- and sound insulation made of materials resistant to moisture, temperature changes.
• After the plastic pipe (7) and a flexible ring seal (6) the air enters the controller unit. With the use of manual mechanical drive (1) built petal rotated, opens and closes the passage.
• The output unit: fine particle filter (4); an insulating insert (3); decorative cover (2) with holes.
• In the assembled state of the wheel (1) protrudes above the surface of the panel (2). If the unit is mounted high for rapid adjustment using strong cord. They rotate drive.

The advantages of the valve compared to other solutions

Conventional techniques using window and balcony door blocks, Characterized by several disadvantages:

• Fine adjustment is possible. Typically, manufacturers provide 1-2 ventilation mode.
• When you open the window (door) formed drafts. Along with the rapid temperature change such conditions promote occurrence of colds, and other diseases.
• This technique does not prevent the penetration of noise, dirt and insects.
• In the room with the windows open It is dangerous to small children unattended.

such articles alter aesthetic characteristics of the initial window (inside and outside). They are more expensive compared to conventional ventilation valves in the wall, have a lower productivity. In many models, there are no filters cleaning up dust, noise protection. They are mounted on top of the frame, making it difficult to access and the operational management.

Wall intake valves are: the differences between various models

Setting the supply valve on the wall with his hands

Pre-need to pinpoint the place of installation.

Figures seen (column 1), which specifically for this model is set housing position. Keep in mind the rules of official instructions to get the necessary ventilation efficiency, but without disturbing the temperature in the room.

According to this scheme set Optima ventilating valve (Domvent):

Picture	Actions
	Positioning holes made by the circuit to the recommended embodiments above. This figure shows how to use available tools to ensure dust removal. Bag and plastic cup fixed masking tape to prevent damage to the decoration of the wall. For drilling use the corresponding diameter nozzle.
	Directly to the pipe itself this valve model sufficiently holes 40 mm. It is drilled with a slight slope to the outside to prevent the penetration of condensate into the room.
	To establish a sound and heat insulation hole is expanded to 65-70 mm. The exact size is set depending on the type of insulation. In this example, the applied mineral wool. But it is better to use a foamed polymeric materials which retain their beneficial properties for a long time in high humidity conditions.
	The housing is fixed in a horizontal position. Before fastening the screws, causing the labeling. Note that in this case the device is mounted on a high altitude. Therefore, a valve with an adjusting lever is directed upward.
	When the housing is securely fastened, put the mechanical filter.
	After installing the cap product is ready for full operation.

This design holds the hard punch in the desired position. With its help create the effort required for fast drilling holes in solid thick walls.

Homemade and special designs

Fresh air valve with his own hands to do is not difficult, if you copy the simplest options discussed above. This requires the pipe of plastic, fine grids, filter material, heater. All of these components are not difficult to acquire in the near specialty store. However, the cost of finished products is low, so the savings would be minimal.

The following are examples that reproduce itself will be much harder.

Such devices at lower temperatures reduce the rate of air inflow. It is particularly advantageous that the respective displacement are performed automatically, without the use of sensors, electromechanical actuators.

Such devices are more expensive. But they purify the air using several stages of filtering. In such models mounted air heating system fans. They are equipped with remote control.
