Undoubtedly, PVC windows are a reliable protection of the premises from extraneous street sounds and the effects of negative environmental factors, but still they have several disadvantages. One of them is the lack of a built-in ventilation system. This design contributes to the penetration of fresh air masses into the room without performing the function of opening the shutters. The solution to the problem can be a window ventilator for plastic windows.
What is this?
Window ventilator (air damper) is a small supply structural system that provides housing construction spaces with a constant supply of fresh air. The air flow is regulated using a special device (feathers), which during windy weather are a barrier to the penetration of cold masses into the room.
Windowventilators are manufactured in different variations. In some of them, sensors are installed that regulate the flow of a certain amount of air masses, depending on the rate of persons in the room. The design performs a protective function from extraneous sounds and dust precipitation. The complete absence of water condensate on the plane of the double-glazed windows of metal-plastic windows is an advantage of using supply structural systems.
Device classification
At this period, structural systems of window ventilators are presented in a large assortment, differing in technical characteristics. They are classified into some categories.
1. By device type:
- Slotted inlet valve. This type is produced in two versions: with a mechanical and automatic principle of operation. It can be made with one universal or two (adjustable and inlet) blocks. The advantage of the slotted valve is: maximum air exchange rate and installation without dismantling windows.
- Rebated window ventilation system. The installation of such a design is carried out by the method of forming seam holes based on the window profile. A feature of the device is a small throughput, the preservation of sound insulation indicators, a budget price, as well as installation that does not require dismantling.
- Slip valve. High level of fresh air flow. Its installation can be carried out only when the windows are dismantled. This type of valve is widely used forventilation systems of industrial premises.
2. According to the principle of operation of the structural system:
- Mechanical control - work with built-in fans connected to the mains.
- Automatic principle - the implementation of automatic adjustment of the flow of fresh air, depending on fluctuations in the level of humidity in the room.
3. By availability of auxiliary options:
Filtration of air flows, forced heating, increased level of sound insulation and others
What types of window ventilation are there?
Manufacturers divide the ventilation device into types that differ in their place of installation and method of its action:
- mechanical control of window ventilation;
- automatic control;
- mounted air valve;
- acoustic ventilation system.
Window ventilators with mechanical control
The elements of this structural system are an internal valve and an external lining that provides protection against dust and insects. Such a device allows you to adjust the level of flow of fresh air masses using the manual method. A clear example of a mechanically controlled design is the Vents window ventilator. Such a device performs several functions: adjustment and direction of air flow, as well as installationvalve to the on/off position.
Installation work can be performed by milling holes on the plane of the window profile, as well as without using this method. In the case of using the second method, the indicators of the flow of fresh air masses are reduced. When installing the ventilator, no dismantling is required.
Available in a variety of colors and low cost.
Automatic window ventilation
At the moment, automatic ventilators are produced in two versions, differing in valve type - pendulum and air:
- The action of the pendulum valve is carried out with the help of a supply air stabilizer that reacts to pressure drops both in the room and outside it. The use of this element makes it possible to penetrate the flow of fresh air constantly and non-stop weather conditions, without reacting to temperature changes in the street. Manual adjustment is also provided.
- The air valve performs its function with a hygrometer and polyamide sensor. The hygrometer determines the humidity of the air, and the polyamide sensor performs the function of adjusting the position of the valve. If the humidity in the room increases, then the valve passage area will be maximum, as a result, the air flow rate will increase.
Automatic ventilators are installed on installed window blocks. Their location can be the upper parts of the sash or window profile.
Window Ventilation Acoustic Systems
Acoustic ventilator - a design consisting of an internal damper, an external grille and sound membranes of different thicknesses. Such a window fixture is very popular among residents of large cities, as it performs the additional function of reducing the level of penetration of external sounds into the room. They are installed in the plane of the profile or double-glazed window.
Window ventilators PO-400 (supply valve)
Elements of the structural system: external visor, filter, adjustable internal grille.
The outer canopy of the PO-400 window ventilator, equipped with a mosquito net, is a barrier to water and insects entering the room. The filter performs complete purification of the air from contaminants, and also retains excess moisture. Internal grille regulates the volume and direction of airflow.
During the operation of the structure, dirty filters should be cleaned by using running water or a new filter should be installed. Judging by the reviews, the PO-400 window ventilator should be serviced at least once every six months.
Such a device is mounted at the top of the window unit. Available in white and brown.
Features of the choice and operation of the device
The window ventilation device must supply the standard air volume, as a result of whichand it should be chosen taking into account the established standards:
- supply valve for private housing construction is calculated at the rate of 30 m³/1 person;
- vent valve for multi-storey buildings - norm 3 m³/1 meter.
When choosing a design, it is necessary to take into account the area of the room and the number of people living in it, as well as the method of installation and recommendations for the operation of the ventilator. The quality indicators of their functioning are directly dependent on the presence of natural or mechanical ventilation in the room.
Window ventilators are used regardless of weather conditions. Their use is especially relevant in the cold season, when it is undesirable to open the doors. They should be mounted in the upper plane of the window. The distance from the floor to the location of the supply air device must be at least 180 cm. The device can be installed as one or more, depending on certain indicators.
Almost all types of window ventilation devices are mounted in rooms where gas appliances are located. Hygro-controlled ventilators are not mounted in kitchen spaces, as spontaneous automatic blocking of the air supply may occur.
According to user reviews, window ventilators can solve the problem of fresh air in any living space and create a favorable microclimate in it.
