Supply valve to the wall. Valves for natural fresh air ventilation

Standards for the design of residential buildings provide for the preservation of the possibility of a ventilation device. There are many concepts on which this task is being realized, but providing a natural air channel is the most popular solution for it.

Depending on the technical capabilities, there may be different options for the organization of the air renewal system. The simplest technology involves the valves of natural fresh air ventilation, which are integrated into walls or window openings. In essence, it is a small plastic or metal channel that forms a shaft for the passage of air currents.

In which cases is a supply valve used

Until recently, the problem of organizing natural ventilation was not so acute due to the weak tightness of houses. Improvement of construction technologies has led to a reduction in gaps and cracks in the apertures and partitions, which was exacerbated by the minimization of pores in the finishing materials. Therefore, almost any modern house or apartment requires the integration of airing devices.

Especially the supply air valve is suitable in houses where compacted windows are used, in which the minimum infiltration coefficient is noted. At the same time, it is important not to forget that any natural channel, although it contributes to air renewal, but worsens other insulating qualities. This applies to the characteristics of heat transfer, and to noise insulation. Another thing is that the valves have different devices, and in some cases it is possible to maintain a balance between these parameters.

Criteria for device selection

Orientation when choosing a device follows several parameters, but the main thing is the ratio between the volumes of the air being removed and the incoming air. The valve should ensure the equality of these indicators.

In some cases, it is necessary to calculate and install several channels. For example, it is possible to integrate a supply valve into the wall in the kitchen, in the living room, bathroom, etc. That is, each room can be provided with its own air duct.

Special attention should be paid to technical rooms in which the availability of gas or other heating equipment may impose special requirements on the characteristics of ventilation devices. To understand other nuances of choice, you should consider the types of valves in more detail.

Varieties of the device

The simplest versions include valves that do not imply adjustment. They keep the capacity of a certain volume in a constant mode.

But more and more often owners of private houses pay attention to adjustable and automatic models. They provide more operational capabilities, as well as reliability. For example, if you install an adjustable supply valve in the kitchen wall, the hostess can adjust its parameters in accordance with the plate usage mode. At the time of intensive cooking, you can open the mine with the expectation of maximum throughput, and then reduce the opening to the optimum value.

Also common are hygro-controlled valves, whose function is adjusted in accordance with the humidity level in the room. These are automatic devices that, by means of a sensor, independently control the position of the ventilation flaps.

How is the supply valve installed in the wall?

Place the valves at a height of about 2 m from the floor. According to the calculations of specialists, this is the most favorable position of the channel in terms of the comfort of residents. In the room served at this level, the air is quite warm, which makes it possible to effectively cool the cold streams in the winter without drafts. It is best to perform such an installation at the construction stage, since in the future installation will require the formation of a special hole.

Install the supply valve in the wall with your own hands is quite difficult, because the operation requires the use of tools for strobileniya. However, otherwise the installation is fairly simple, and even a layman can cope with it.

When the niche is ready, all fixing procedures can be carried out using the tools included in the valve kit.

Features of installation in window openings

In some ways, such an installation option is easier than in the case of a wall. Theoretically, this channel can be mounted in both wooden and plastic windows. But only on condition that the introduction of this vent component does not reduce the strength of the entire box.

For installation in the profile, it is necessary to create a hole, and on the outside to provide a protective visor. But there is another way to solve the problem.

Many manufacturers of frame structures from PVC even at the design stage allow the technological possibility of integrating such climate devices. The user can only determine which supply air valve for PVC windows is better in terms of the reliability of the entire structure.

It is desirable initially to focus on the model of the same brand that produced the window system. If such products are not on the market, then preference is given to valves that fit the size.

Feedback from the user of the air intake valve

Properly implemented system of supply valves, according to the owners, provides an effective drainage of exhaust air by replacing it with fresh streams.

The most positive feedback comes from models with automatic leaflet adjustment. The convenience of their operation and the optimal parameters of the microclimate formed are noted.

Also, many owners appreciate the work of the filter, which can supply a supply valve to the wall. The reviews emphasize that the availability of such a system eliminates the need to purchase special humidifiers and other climate equipment with a cleaning function. In this case, the valve itself is not so expensive compared to domestic air conditioners and split systems.

Conclusion

The trends in the ventilation systems market show that the consumer is increasingly turning to simple but effective solutions. Excess functional and complex configurations, used to optimize the microclimate characteristics, give way to elementary devices whose operation is easy to manage and energy-efficient.

Users who install the supply valve in the wall, almost do not complain about the shortcomings of the operation of such devices. The only problem that causes concern for many consumers even at the stage of purchase, is the installation with the creation of a hole in the wall. Indeed, this is a laborious and in some cases costly operation, but you can choose a simplified integration scheme in the form of an installation through a window box.
