Supply valves in the wall: prices, installation. Supply air vent
Need to create special channels beforerecently and was completely absent. The function of natural ventilation was provided by defects in the house in the form of cracks, large gaps and bridges of cold. However, with the improvement of construction technologies, the walls and finishes became more airtight, which necessitated the introduction of special systems for air exchange. To date, supply valves in the wall are the simplest means of ventilation, which is implemented artificially. The efficiency of such installations depends on many factors, including installation, climatic conditions of the terrain and configuration of the location of the system.
Types of inlet valves
Inflow valves are available on the market intwo main versions. These are models with constant ventilation, and options with the possibility of adjustment. In the first case, the owner receives a device that provides the same parameters and volumes of air exchange. In an extreme case, the permanent supply valves in the wall can be completely closed for the time of departure. Usually such a choice is made due to atmospheric conditions, when the pressure drops outside and in the room are very different. Models with the ability to adjust more technologically, more functionally and more profitable from the point of view of ergonomics. Special management of such devices is due not only to the interests of ease of operation, but also to more productive operation of the system. These are valves in which the throughput is adjustable - the user can adjust the intensity of the air flow depending on the conditions.
In which rooms to install?
During the selection of valves, thebe guided by the needs of specific premises. It is important to take into account that air masses from living rooms are inflow to the toilet, bathroom and kitchen, as they are removed by means of the ventilation channels located there. Taking into account the capacity of the supply valves, the number and location of the installation are determined. There are two approaches to determining the number of valves for installation in the house. According to a simplified scheme, the inlet valves in the wall must be installed in each room. A more economical configuration involves calculating the needs of a house or apartment in the open air - further, in accordance with these indicators, the capacity for each room is determined. Most of all difficulties in the planning process is caused by the kitchen, as there are certain limitations when combining valves and household appliances. For example, if there is a gas stove in the room, then a model with an adjustable capacity should be used. If the kitchen is provided with a boiler or stove, then a model with a permanently operating valve is recommended for safety.
Identify installation points
It is desirable to install the valves onlevel 2 m from the floor surface. This arrangement is most rational in terms of the comfort of the residents. In addition, if the room is heated, then the air at this level will be warm enough. In winter, this approach will also help to get rid of drafts. The installation itself can be performed in the upper window part or in the doorways. However, experts recommend the installation of supply valves in the wall, since this method will ensure reliable fixation of the device and will not cause any special problems with dismantling. For comparison, if you install the valve in a door or window box, you will inevitably have to revise the design of the system's media, and this will entail additional costs.
Installation technique
During the installation, a speciala hole for the valve, after which the free niches are sealed, and also a protective visor is introduced. The installation of a supply valve in the wall can also be carried out in combination with a special profile. In this case, the device will be integrated into the protective case, which will facilitate the fixing process. But there is also a minus in similar solutions - they will occupy more space in the wall and will require the creation of a hole of a larger diameter.
In general, wall valves are recommendedto install at the construction stage, as in the finished house this event will cause much more trouble. As an alternative solution, you can also provide for installation through special openings, but in this case, you can lose the warranty. In addition, the installation of a supply valve in the wall can be carried out either in a living room or in the kitchen. Due to humidity, such installation is not allowed in the bathroom.
Methods for regulating valves
It has already been noted that some types of valvesallow you to adjust the parameters of their work. In particular, there are systems with automatic and manual regulation of the volumes of supplied air, the degree of filtration and even the level of humidity. Models with manual tuning are usually equipped with a special leaf, in which the position changes and, accordingly, the capacity is adjusted. If it is planned to install an air inlet valve to the wall without the user's intervention in its adjustment, automatic models should be purchased. Such devices independently control the flow capacity depending on the pressure, the humidity level of the air and the temperature from the outside.
Price issue
In the simplest versions, the ventilation valvesare inexpensive. Only for 500-700 rubles. you can buy a good model from a well-known manufacturer. However, if you need several devices with installation for a long period, it is better not to save and purchase more technological and reliable supply valves to the wall, the price of which will be about 2-3 thousand rubles. These can be hygro-controlled devices that react to changes in humidity levels and independently change operating parameters. The most expensive models include a sensor made of a polyamide tape that controls the flaps, increasing or reducing the flow of air. Also, the installation costs that can be quite impressive when installing the valve in the wall should be considered. As a rule, specialists install devices purchased at their own companies with significant discounts, but still the cost of this part can be 1-2 thousand rubles.
Feedback on the effectiveness of the valve
Despite the simple design and widePossibilities of managing such systems are not widely spread. Nevertheless, there are many consumers who use such valves in private homes. They just leave positive feedback on the performance that the homeowner who installed the intake valves to the wall receives. Criticism of this approach to ventilation is based on two points. Firstly, full-scale forced air conditioning systems cope with this function. Secondly, interference in the wall for the sake of such a minor adaptation does not justify itself - again, with a similar trouble you can introduce a more functional system.
For which houses is the supply valve suitable?
Either way, and a small valve with ventilationcan be useful. It is advisable to use it in houses that are operated in conditions of sharp temperature changes, but do not require the provision of large volumes of air exchange. It is important to understand that the supply ventilation valve in the wall is to a large extent a filling element of natural ventilation. That is, one should not expect high efficiency from it, but one can expect to correct the microclimate.
Conclusion
The market offers different models of air supply systems,so to judge the very principle of their work with only one design is not worth it. Even within the family there are quite different in terms of the capabilities of the system. For example, if you integrate the supply and exhaust valve into the wall with the possibility of automatically adjusting the operating parameters, this will ensure the maximum ventilation function without the use of overall equipment. A compact device, neatly embedded in the wall, will not spoil the facade of the building, but it will provide autonomous control of the air environment inside the premises. With regard to costs, they are minimal in comparison with special climatic equipment, so you can count on the economics of such ventilation.
