Normal air exchange is necessary for any room. However, it is not always possible to install a mechanical ventilation system. The best option is a ventilator for plastic windows. It provides housing with fresh air, which will flow constantly, which will eliminate drafts and condensation.

Ventilation of rooms

The easiest way to ventilate rooms is to open windows. However, it is not the most effective. Along with fresh air, they penetrate into the home harmful substances outside. This is dust and exhaust gases from road transport, and also cold. Near nearby industrial centers such ventilation is practically impossible.

Now they have begun to produce PVC windows with micro-ventilation mode. In them, it is enough to turn the handle 45 degrees so that a gap appears between the frame and the sash. Air from outside will pass through it. With this method there is almost no noise, and the amount of pollution is minimal compared to an open window. However, the volume fresh air With such ventilation it is not enough for the room.

Another good way to ventilate a room is to install a limiter (comb). The system is attached to window frame and makes it possible to adjust the ventilation gap. This is an inexpensive method, but it does not solve the main problem - access to fresh air. Cold and noise in ventilation mode penetrate into the living space.

They also produce designs with stepped ventilation mode. This ventilation system in plastic windows works like a comb. When you turn the handle, several positions open with different sizes cracks.

Self-ventilated windows

After installation modern windows Made of plastic, they provide almost complete sealing. For high-quality ventilation, self-ventilated structures were invented. They can be installed in almost all civil and industrial buildings.

In this option, ventilation holes are made in plastic windows. The holes in the profile are located at the top and bottom of the frame. Through bottom part air masses pass through, after which already heated air enters the room. The system works quite effectively, but it has some disadvantages. For example, apartments on the upper floors will receive insufficient air. For this reason, special ones were invented.

Optimal valve options

This device for window ventilation is considered relatively simple. However, it has design differences depending on the variety. To understand this, you should know the features of all valve options.

Seam valves are considered the most inexpensive and simplest. Holes in allow air to enter the room through small cutouts. The features of this design are as follows:

• low price;
• possibility of installation without dismantling PVC windows;
• simple and quick installation;
• guarantee of high sound insulation of double-glazed windows;
• possible automation.

Despite all the above advantages, this type of valve has one significant drawback - poor throughput. This can be felt well with the windows closed.

Air enters the slots through special valves. They are equipped with two blocks: inlet and regulating, and in more modern models only one block of universal type. Among the advantages of the technology are:

• thanks to the control unit there is complete protection against various external factors eg sediments and insects;
• good throughput;
• use without dismantling the glass unit.

A serious disadvantage in such valves can be called relatively complex installation. However, in some models this drawback is eliminated, for which they are very popular.

There are overhead models, but they are practically not used for residential premises. This is due to the major shortcomings of the valves. They significantly reduce the thermal insulation efficiency of windows, and sound insulation is also completely absent. Such valves are usually installed before installation begins. window designs. This is due to preliminary adjustment of the opening. In the manufacturing sector, this type of supply ventilation has found wide application. The demand is due to its excellent throughput.

Ventilators for plastic windows

Criterias of choice

During operation of a ventilated window, it is necessary for the supply ventilation to function effectively. Each valve option has its pros and cons. To do right choice, the following characteristics must be taken into account:

Experts advise not to consider options in which it is not possible to adjust the valve. During their operation, the need to change the air flow is mandatory. Usually they make mechanisms with manual, automatic and mixed settings. It is advisable to choose a tandem from the first two. Supply ventilation will be most effective if exhaust ventilation fulfills its function. any design is easy to maintain, and this is another advantage. The basic rule of maintenance is to clean the surface from dirt. which is done once a year.

Depending on the design mechanism, its structure varies. The air flow can be regulated or it will work in constant mode. To create an optimal microclimate in the room, it is advisable to give preference to models with the ability to adjust.

The automatic setting mode is considered the most comfortable. In such a mechanism, when changing optimal parameters regulation occurs. The hygroregulation sensor in the room monitors humidity levels. It can change the air flow section in several modes and even completely close access. This type of control device can significantly reduce heat loss. When there are no people in the room, ventilation does not occur.

At manual way ventilation, you need to think independently about regulating the flow of fresh air. The valve operating time is selected manually by the person himself. Limit air flow With this setting, only strong winds are capable.

When operating such a system, drafts occur in the room, which is harmful to health and uncomfortable. Normal flow of fresh air from automatic tuning will relieve bad health and mood.

Helpful information

Installing plastic windows can lead to disruption of the microclimate in your home or office: increased humidity, lack of oxygen and stale air. Such problems can be easily eliminated with the help of supply valves on window openings.

The TBM-Market company has big choice window ventilators from leading Russian and global manufacturers. They normalize natural ventilation and stabilize air exchange in residential or non-residential premises.

Advantages of supply valves

The valve consists of an internal controlled grille with adjustment and an external visor. The last element blocks precipitation from entering the house and is equipped with a protective mesh against small insects. An internal controllable part allows you to set the amount and direction of movement of fresh air.

The features of window ventilators include the following:

• the light zone of the glass unit remains free;
• absence of drafts, like from an open window;
• the influx of street air occurs organically, in full;
• there will be no heat loss;
• maintaining sound insulation;
• you can set operating parameters, especially if it automatic systems;
• easy installation and use.

The ventilation valve looks like a narrow box that is attached to the crossbar of the window opening. The internal parts, called feathers, are responsible for the flow of air from the outside. In good weather, the device allows air flow into the apartment, and in strong winds, the feathers block the cold from entering the room. Due to the fact that the ventilation is automatically regulated, there is no need to open the windows for ventilation in the morning and evening.

Classification

When choosing a supply valve, you can rely on the following criteria:

1. Release material:

• metal;
• plastic.

• mechanical adjustment, where the desired level of ventilation is manually set;
• automatic option, when the element itself determines the period of opening/closing of the supply channel depending on humidity, pressure surges in the room, the number of people in the house, etc.

• Seam mechanism, when air flows pass through small holes in the shutter. There is no need to dismantle the window, but the valve's capacity is low, and sound insulation qualities may suffer.
• Slit systems, where air enters the room through an opening up to 16mm high. The outside of the system is covered with a protective block against small insects and moisture. The internal part is represented by a regulating flap. Installation is carried out on the upper vertical or horizontal crossbar.
• Overlay elements. Installation is not performed on an existing double-glazed window.
• Wall-mounted mechanism, where air exchange passes through a hole in the wall and plastic pipe. This expensive but effective device comes on sale with forced heating or filters for air purification.

• With built-in valves that come with PVC windows.
• With milling, when the element can be purchased after installing the double-glazed window.
• No installation.

• Russia;
• France;
• Germany.

TBK-Market consultants will help you choose window ventilation to create an ideal microclimate in your home, office or industrial premises.

Plastic windows help keep the room warm and keep cold and sound out. But at the same time, they significantly reduce the flow of fresh air. This omission of the designers can be corrected by installing a supply valve on the windows. The main task of the device is recovery natural ventilation in a commercial or residential area.

The need to use a supply valve on plastic windows

The benefits of using plastic windows have been appreciated by many residents of apartments and private houses. Comfortable, beautiful and practical windows can reduce heat loss and increase noise insulation of the room. However, along with the advantages, consumers also noted one significant disadvantage - lack of ventilation. This factor worsens the microclimate of the room - humidity rises, the air becomes stale, and people in the house begin to experience a lack of oxygen. As a result, mold appears on the walls and slopes of the room, and the concentration of toxic substances increases.

For normal existence it is necessary to restore sufficient air circulation. Ventilating an apartment by opening window vents nullifies all the advantages of sealed “plastic” and significantly reduces heating efficiency. Inlet valves can solve the problem.

A supply valve is a device installed on the top sash of a window in a horizontal position, which performs an exhaust function. The valve maintains an optimal microclimate in the room and eliminates condensation on the glass unit and frame.

Feasibility of application supply valve on plastic windows due to a number of advantages:

• the light opening of the window remains unchanged;
• there are no drafts in the apartment, as with normal ventilation;
• the flow of fresh air is at a sufficient level;
• there is no heat loss during valve operation, and the sound insulation of the room remains at the same level;
• ability to regulate valve operation;
• ease of installation and operation.

Design and principle of operation of the supply valve

Proper arrangement of window ventilation is possible only if you have a complete understanding of the mechanism of operation of the supply valve.

When installing the valve, a part is removed rubber seal on the window frame and sash. A thinner special seal is installed in this place. Together with the new seal, a supply valve is also installed on the window sash - the main element of passive ventilation.

Air from the street is sucked into the room, and warm air it is pushed out through the exhaust ducts. Air circulation occurs due to pressure differences. Natural air exchange works if the outside air temperature is not higher than +5°C. In hot weather, ventilation operates using forced exhaust.

The window ventilation valve consists of the following components:

1. The outer part is the “air intake”, installed with outside frames Required condition- the presence of a visor above the air intake, which prevents rain, snow, etc. from entering the valve.
2. Telescopic channel - passes through the frame. The element is milled into the plastic window frame and fixed with a sleeve.
3. An internal part installed from inside the room. The most complex unit, which is equipped with an exhaust nozzle, a simple filter and a mechanism for adjusting the throughput.

Basic conditions for the operation of the supply valve:

• proper exhaust ventilation in the apartment;
• air temperature outside the window from +5°С;
• free air exchange between rooms in the apartment - cracks under interior doors not less than 2 cm;
• sealed entrance door.

Advice. Job exhaust ventilation You can check the apartments yourself. Close the door to the room tightly and open the window in the room as far away as possible from ventilation duct. Attach a sheet of paper to the grill. If it does not fall and is held by the air flow, then everything is fine with the hood

Types of supply valves for windows

There are many different models and variations of window supply valves. They differ from each other according to different criteria.

According to the material of manufacture:

• plastic;
• wooden;
• metal.

By control method:

• automatic;
• manual.

When operated manually, the valve is equipped with a special rope. Automatic valve more convenient to use. The device independently determines the need to open/close the ventilation hole. The adjustment indicators are set in accordance with the humidity level and pressure differences in the room.

Important! Operating the inlet valve manually is a bit risky. Required level selected by trial and error. In addition, there is a risk of freezing if incorrectly adjusted winter time

According to the method of air entering the house:

1. Rebated inlet valves. One of the most economical options for PVC windows. Cold air supplied into the room through small cutouts in the vestibule. To install such a valve, the windows do not need to be dismantled. Seam valves have low throughput, sound insulation is at a sufficient level.
2. Slotted inlet valves. Air enters through a gap whose height is about 16 mm. On the outside of the window, the valve is covered with an inlet block (protection from precipitation and small insects). The inside of the device is closed by a control block. Installation of the slot valve is carried out in a horizontal impost or upper bar of the sash. The advantages of such a valve: high throughput and the ability to install without dismantling the window.
3. Overhead valves allow air to pass best. However, the size of the window opening and frame must be “adjusted” to the valve. The overhead valve cannot be installed on installed double glazed window. Such valves are usually used in production and warehouse areas.

An interesting variant of the valve-handle, which is installed instead of the usual one window handle. Such a device has a number of advantages:

• the appearance of the window does not change;
• the ventilation valve can be located in the place where condensation most often appears;
• effective removal of excess moisture;
• the valve does not freeze in winter (the device has a direct-flow design);
• The handle valve has a built-in filter that prevents dust from entering the room.

Selecting a supply valve: review of manufacturers

Choosing a supply valve from a wide range of models is quite a difficult task. Let's consider General characteristics products from the most popular manufacturers of fresh air ventilation. After all, conscientious companies in the vast majority of cases produce a high-quality product.

The French company Homearea produces supply valves Aereco. Operating principle air supply devices is based on a change in the flow area depending on the level of humidity in the room. Air circulation is carried out under the condition of mechanical or natural exhaust operation.

The most common manufacturer models:

1. Aereco valves of the EMM series are moisture-sensitive, hygro-adjustable. The valve has two mounting methods, which characterize the air supply options - with an inclined or vertical jet direction. It can operate in two modes: “minimal ventilation” and “automatic”. Air consumption up to 35 cubic meters/hour at 10 Pa.
2. Aereco valves of the EHA series are equipped with a hygroscopic sensor-drive, which ensures a healthy microclimate in the room. The set includes acoustic accessories that perform noise-absorbing functions. Air consumption - up to 50 cubic meters/hour at 10 Pa.
3. Aereco valves of the EHA2 series are available in a stylish slim body. The device guarantees sound insulation of the house up to 42 dB. The inclined air flow is directed to the ceiling area. This ensures progressive heating of the street air. The device has three operating modes: minimum, automatic and maximum air flow.

Inlet valve for window Air Box Available in three trim levels: Standart, Comfort without milling and Comfort-S.

The Comfort model is installed in two ways - with/without milling. Milling - drilling or sawing at the top of the ventilation duct sash.

Important! Milling doubles the performance of the supply valve. But usually a standard installation - without milling - allows you to solve the ventilation problem

The Comfort-S damper is designed for installation on fixed windows. Installation of such a valve is quite labor-intensive, as it requires drilling a reinforced steel profile. Typically, the Comfort-S valve is installed at the factory.

Passive ventilation supply valve - installation Regel-air. Ventilation of the room occurs automatically. Depending on the temperature in the room and outside, the device independently regulates the degree of ventilation.

The Regel-air climate valve has the following advantages:

• affordable price;
• hidden installation - when the flap is closed, the valve is not visible;
• the incoming air circulates inside the frame - the air temperature rises;
• high maintainability;
• The sound insulation of the room does not deteriorate.

How to install a supply valve on a window: step-by-step installation

The ventilation valve can be installed on the window in two ways: with or without perforation. Let's consider both options.

Installation sequence of a climate valve with perforation:

1. Preparation of tools:
   • electric drill;
   • jigsaw;
   • file;
   • drills 5-10 mm;
   • construction knife;
   • template for marking valve contours;
   • sealant.
2. Using a template, outline the location of the supply valve. The marker must be attached to the top sash. For this work, it is better to remove the window sash, since the marking is carried out from the outside and from the outside. inside details.
3. Drill several according to the markings through holes 5mm drill bit. This row will serve as the base for larger perforations.
4. Drill the prepared holes with a 10 mm drill. For convenient location of the valve, holes are drilled from the inside of the window sash.
5. Expansion of the supply valve. Between the pair of outer holes, use a jigsaw to cut out the remaining material. As a result of the work done, a through gap should be obtained. Sand the edges of the hole with a file.
6. Install the valve mounting strip on the flap surface and secure with self-tapping screws. The part must first be treated with sealant.
7. Mill a groove in the frame overlay. Mark the position of the supply valve according to the template, and then cut out the groove using a jigsaw and file.
8. Install the outer part of the climate valve with a visor on the outer surface of the frame. The part is fixed with self-tapping screws and sealed with sealant.
9. Assemble the sash and install it in place - on the hinges of the frame.
10. Check the position of the holes in the sash and frame overlap.
11. Commit inner part valve on mounting plate. Use clips and latches as fastening elements.
12. Adjust valve operation.

Let's look at how to install a supply valve on a plastic window without resorting to perforation:

1. For installation work prepare:
   • a regular cross-head screwdriver;
   • stationery knife;
   • marker and ruler.
2. Open the window sash and remove part of the seal that seals the gap between the frame and the sash. The old gasket is cut off with a knife from the frame overlap. Stick a special gasket, which comes complete with the supply valve, onto the free space.
3. Direct valve installation:
   • install three plugs with the “skirt” down in the grooves from the seal;
   • fix the valve on the flap of the sash - the device is attached from above in the direction of the brackets to the window;
   • secure the valve with self-tapping screws passed through the brackets;
   • Install a seal in the groove between the brackets.

In this case, the gap between the valve and the seal on the frame acts as a ventilation duct.

Adjustment and operation of the supply window valve

The supply valve can be controlled manually or automatically. Automatic is more convenient and is usually supplemented with a hygroregulation sensor. When humidity decreases, air flow decreases, and vice versa - air circulation increases when humidity in the room increases.

With manual control, you can make mistakes, which sometimes lead to overcooling of the room and freezing of the climate valve.

Important! IN very coldy the inlet valve cannot be completely closed

Maintenance of the ventilation valve is limited to cleaning every 6 months. Dust from the external visor can be removed with a vacuum cleaner, and the body can be wiped with a damp cloth.

Cannot be used for cleaning chemicals. In addition, you should refrain from cleaning the device under running water. running water. When carried out indoors repair work the valve must be covered - this will protect it from dirt and dust.

Supply valve for PVC windows - practical and necessary purchase, which improves the microclimate in the house. You can install the supply valve on plastic windows yourself. The installation method depends on the valve model and its configuration.

The installation of PVC windows, invented in Germany in the post-war years, has become widespread. At the same time, a tendency has emerged to install ventilation in apartments with plastic windows. What are the reasons?

Residents appreciated the advantages of windows not by chance. The apartments have become warmer, since the windows are sealed and have no cracks. They look more impressive and neater than glass predecessors, and are more convenient and easier to clean. Closed windows They protect well from street noise and polluted dusty air.

Glass frames, unlike PVC windows, allowed air flow through the cracks in the openings; in winter it was necessary to fight drafts, insulate, caulk, and seal with paper. This deficiency was compensated by fresh air; I could breathe easily and freely.

Air exchange of an apartment with plastic windows

Owners of modern windows soon felt the inconvenience:

• especially in winter, when it is impossible to open a window or window sash for ventilation;
• in summer the plastic heats up, the heat and stuffiness intensify;
• from condensation causing mold and allergic reactions on her;
• lack of oxygen, resulting in poor health and sleep.

The acute question arose of how to additionally ventilate the room.

Natural ventilation

Air exchange in the home removes unsuitable air from carbon dioxide, microbes and fungal spores from the apartment, exchanging for air flow from the street.

The street flow naturally enters the apartment through the open windows. In winter it calls colds, in the summer, pollution particles come from the street.

In old-style houses, exhaust vents were installed in the most polluted places. The trouble is that utility services are not always responsible for cleaning ventilation shafts, the exit hatches of which are located at the top. It’s easy to check the operation of the hood; place a piece of paper on the hole; if it doesn’t fall, it means the exhaust air is escaping.

Ventilation is carried out by another in a simple way. A hole is made in the wall next to the heating battery to the street with a channel for the circulation of an air stream heated inside.

Forced ventilation

IN modern houses Numerous manufacturing companies install ventilation structures during construction or renovation.

The principle of operation of any device is that a fan supplies air to the filter system for cleaning. Forced ventilation brings supply air into the home.

1. The air supply unit is usually equipped outside; air that has passed through the filters enters the home through a special channel. It can be supplied to certain areas of the apartment by branching from the main air duct;
2. Exhaust fans are often installed in kitchens, bathrooms, and toilets to eliminate odors, excess moisture, and smoke. A way is needed to restore the atmosphere inside to supply oxygen instead of waste carbon dioxide.
3. The supply and exhaust mechanism is installed on the ceiling, on the floor, in hanging form, in any part of the apartment;
4. The supply and exhaust unit operates in recirculation mode when using a recuperator (cooling the internal air in summer and heating it in winter when passing through the air conditioning unit).

For system equipment it is important to know:

• the dimensions of each room of the apartment;
• humidity;
• ecological space around the house, street pollution.
• number of residents and children in the apartment;
• presence of patients with allergies and asthma.

Conclusions are taken into account when planning the estimate ventilation units, quantity, traction force and energy costs.

For ventilation in an apartment with plastic windows, install:

• electric fans connected to the air duct in the kitchen and bathroom;
• ventilation valves small sizes mounted at the joints of frames, allowing limited air exchange;
• two-way supply valves are often installed above the top panel; through plastic pipes, the air stream passes through cleaning filters from the inside;
• Exhaust fans pull unsuitable air out of the apartment, while blocking the street inflow.

It is advisable to construct a ventilation system during the renovation of an apartment or the installation of plastic windows. Experts calculate the indicators and add ventilation systems premises of the apartment to a common air duct, install supply and exhaust valves on all windows. The most economical and a budget option, perfectly cleanses the atmosphere of the house

For an additional fee, you can equip the structure with sensors that can automatically regulate the level of pollution in the air space of the apartment, heat exchange and noise penetration.

Types of ventilation devices

Inflow clean air ventilation mechanisms are provided in the apartment different types presented on the market in a wide variety.

A device with an exhaust hood and an influx of heated air at the same time is in demand. It looks like a small box with two fans, a filtration system, a recuperator and a control unit. Mechanical device hangs on the wall, does not require energy consumption.

There are mechanical and electrical devices based on their operating principle.

Hoods installed above kitchen stoves, fans, air purifiers with heat exchange in the bathroom, toilet, and other rooms can be turned on automatically along with electricity or by mechanically pressing a button.

Electrostatic ionizers saturate the purified air of the apartment positive properties for good health.

Example of an air purifier with ventilation method internal space premises through the passage of several filters.

1. The primary pre-filter consists of foam rubber or plastic mesh that are easy to wash and dry. Detains coarse dust, particles of pet hair, fluff, and hair. The better its quality, the longer the service of subsequent filters.
2. Filters are installed behind it for smaller dust particles with bacteria and fungi, which, when breathed, enter the lungs and cause significant damage to human health, especially those with asthma and allergies. Nera filters capture the smallest dust particles and purify the air up to 99%. The more filters, the better system cleaning.
3. The last filtration is with activated carbon, in which volatile microparticles settle and are retained, and unpleasant odors go away along with them.

Instead of activated carbon air can be filtered by passing through water.

Mechanical devices do an excellent job of cleaning the microclimate inside an apartment; they are economical to use, but are expensive and require additional action to clean the primary filter, replace water, etc.

A correctly selected method of ventilation of an apartment with plastic windows should be silent, without temperature changes, with normal humidity, air environment maintain a cheerful mood and health.

Windows with ventilation valve: advantages and disadvantages

To eliminate window fogging and allow fresh air into the room, supply ventilation valves were developed. They are installed directly into the frame of a plastic window or into the wall next to it. Among the advantages ventilation valves:

Ability to regulate air flow, including in automatic mode;

High level of noise protection;

Original design;

Possibility of installation on existing windows.

Among the disadvantages of the ventilation valve is its freezing, which in winter leads to disruption of its operation. This is due to the fact that most products on our market are presented European companies, who developed valves for countries with milder climates.

The disadvantages of ventilation valves include the relatively high cost of the equipment, which significantly increases the price of a regular window. When using PVC windows with ventilation, you should remember that positive effect will be possible only with proper operation hoods

Ventilation systems for plastic windows

If there is a lack of funds or doubts about the effectiveness of ventilation valves, you can provide supply ventilation due to the installation of special fittings.

An alternative to windows with a ventilation valve can be window combs, handles with child protection or handles with a micro-ventilation function.
