Ventilation in a room without windows - how to do it in a “dead” room?

It happens that in a building there is a “dead” room without windows. This situation can also be observed in apartments, for example, after redevelopment or on the first floors with access to a busy street (which is why they are covered with bricks). They are also made in private homes: these are boiler rooms, storerooms, garages, and basements.

Even more often, such rooms are found in non-residential buildings: in warehouses, in office premises, in shopping centers. Sometimes they are used as a dressing room or storage room. No matter how “unnecessary” such a room may seem, it is necessary to install a ventilation system in it.

The role of air circulation systems

Ventilation in a room without windows plays a big role.
Even if a room is rarely used, carbon dioxide accumulates in it. If more than one person is constantly in the room, 60 watts of heat per hour is generated and excess moisture is created, which settles on the walls in the absence of natural or artificial ventilation. As a result, it will be very stuffy, and fungus will form on the walls, the spores of which are dangerous to health. Transparent ventilation ducts are not always able to provide enough fresh air, even if there is a window in the room. The fact is that hollow plastic products reliably insulate the room. There are positive aspects to this, but there are also disadvantages, for example, the room is not ventilated. Using special equipment, you can solve the problem: the system will forcefully provide ventilation to the room.

Results and conclusions

The microclimate in the apartment and the well-being of everyone who lives in it depend on the ventilation in each room. Ventilation is most needed in rooms without a window, where there is always a high risk of air stagnation and mold development.

Using a modern range of equipment for organizing air exchange, you can easily organize normal ventilation with your own hands.

The variety of devices designed to solve this problem allows you to create an effective ventilation system without high financial costs.

Why is ventilation needed in a “dead” room?

Having a ventilation system in a room without a window is mandatory. This question should under no circumstances be questioned, since there are no other ways to maintain an optimal microclimate and air exchange in a “blind” room.

If the owner of the house thinks that without ventilation nothing terrible will happen, then he must be prepared for the consequences:

• musty and stagnant air in the room;
• the appearance of moisture and, consequently, mold.

Probably, not many people want to deal with such problems, so the question “To do or not to do ventilation?” disappears immediately. However, before you begin installing the system, you need to learn more about the ventilation options available.

Is a fan needed?

As has already been said, the natural ventilation of the dressing room does not always provide sufficient air movement speed and a musty smell still appears. This usually happens in the summer, when it is too hot outside and natural air movement is minimal or the draft generally reverses (air masses move in the opposite direction). In such cases, fans are installed on the exhaust openings. Their power is selected depending on the volume, but as a rule, the lowest power ones are sufficient - 10-50 cubic meters per hour. In this case, the main selection criterion is quiet operation. After all, many dressing rooms open onto bedrooms or other living spaces.

Fans may vary. You can even use computer coolers

Many people find it intimidating to install fans—they have to run almost 24/7. In general, not necessarily. It is quite enough if it turns on for 15-20-30 minutes every hour. This mode is provided by timers, controllers and other similar devices. All that is required is to select the operating mode and set the appropriate settings.

Yes, this is an additional expense, but the forced ventilation of the dressing room works constantly and does not depend on the vagaries of the weather.

Air exchange requirements

When designing an air exchange system, it is important to follow recommended standards.

The calculation is based on the use of the room, so the following factors must be taken into account:

• approximate number of people in the room;
• frequency of presence in the room;
• purpose of the room. In recreational areas, 30 cubic meters per hour per person is sufficient. For active recreation (eg sports) this number should be doubled;
• indoor humidity level;
• the presence of hazardous substances, for example, in paint shops or storage areas for household chemicals.

The minimum air flow in the rooms is 30 cubic meters per hour per person. In the presence of harmful factors, depending on the intensity of their impact, this number increases several times.

In other cases, it is recommended to stick to a value of 32 to 35 cubic meters per hour.

You should also take into account the level of carbon dioxide in the air. For small towns - 800 mg/m3, in polluted areas of a metropolis - no more than 1000 mg/m3, in rural areas - no more than 650 mg/m3.

When creating an influx of fresh air, do not forget about the comfortable noise level that a special fan can create. It should not exceed 35 dB.

Ventilation devices

Ventilation can also be achieved using special devices. They are divided into groups depending on the direction of air movement inside. In practice, the following classification is most often used:

1. Inlet.
2. Exhaust.

The installation specification directly depends on the type chosen. Additionally, system requirements and characteristics should be taken into account. For example, a ventilation valve is installed directly into the wall itself. That is why the layout of the building and diversion routes is of key importance here.

Wall ventilators help eliminate unpleasant odors in office premises. They are also installed in the kitchen, toilet or bathroom. If necessary, the flow of fresh air can be organized in rooms of another type.

Ventilators for PVC windows

Window ventilators also help organize the necessary circulation of air masses. The most common installation method is a hole in a window opening or a special grille in plastic windows. In practice, another classification of all devices used is also used:

• Depending on the specification of the method of air penetration into the room: mechanical or natural.
• The service space plays an important role: local or general purpose.

Modern supply and exhaust systems help organize the flow of fresh air at any time of the year through the use of purifiers and filters. At the same time, they do not have a negative impact on the temperature in the room, since they use recuperators. Their choice is also preferred by institutions.

Natural ventilation

When designing an apartment with a “dead” room, install ventilation ducts in the walls for natural air exchange. They take the form of a small hole in the wall covered with mesh or grating.

If there is no such hole or if the draft through it is not very good, then the air in the “silent” room will be stuffy. In this case, installing a fan on the ventilation duct or installing special air intakes that force air masses to move, if the specified ducts do not exist at all, can help.

Another way to improve ventilation is to ventilate the entire apartment. However, this option is good only in the warm season; in winter, due to ventilation, condensation will form on all surfaces in the room.

Types of ventilation

The ventilation system is selected depending on the time of year. The duration and quality of air exchange directly depends on this parameter. SanPiN mentions two types for ventilation:

• Through. In this case, all available windows are opened and thereby ensure maximum circulation of air masses in a short period of time.
• Corner (one-sided). This type is used mainly in the warm season.
• Through the ventilation system shaft. This is the most common type of continuous air exchange, which increases when windows or air supply units are opened.

Forced ventilation

Natural ventilation is not always enough for proper air exchange in a “dead” room, therefore, to normalize the microclimate, a forced method is used - ventilation with fresh air.

Its system consists of an opening in the wall and a damper with a dowel. Often, the supply air exhaust in residential premises also has a fan, a heater and a filter for cleaning the air masses.

Self-installation of supply ventilation is not difficult, any homeowner can install it, the main thing is to know the stages of work. First, a hole is punched in the wall sheet; this can be done using a punch and a special nozzle. The hole is then filled with insulation and a piece of plastic pipe is placed over it. Construction work is completed by filling the empty spaces in the hole with ordinary polyurethane foam.

On the street side, the pipe must be covered with a special grill. This is an element that prevents dirt from entering the ventilation valve from the outside. From the inside of the room, the air duct is closed with a plug, which allows you to regulate the air suction.

It is worth noting that such a system is capable of creating a comfortable microclimate in the room. But in winter, homeowners will need additional ways to heat a “silent” room.

For those who want to save on heating costs in winter, prefabricated structures for ventilation are suitable.

Ready solutions

Manufacturers of split systems have taken care of simplifying the ventilation of “silent” rooms and offer consumers high-quality and efficient forced ventilation devices with climate control options.

Aerohydrohod is a convenient device that helps speed up the movement of air masses, while perfectly filtering the air from dust particles and allergens. The appearance of the aerohydrate is remarkable, so it will not spoil the facade of the building or the interior of the room, and its operation is silent, so the device can be installed even in a kindergarten.

However, the main advantage of this device is that the “dead” room is ventilated around the clock, and the air passing through it will no longer heat up.

An air conditioner is an appliance that many people are familiar with. As it turns out, this split system is ideal for room ventilation. Modern models are designed not only to dry air masses indoors, but also to bring in fresh air from outside.

Some conditioners also have ion enrichment and allergen purification features. Considering all these advantages, we can confidently say that split systems with air conditioning are an excellent replacement for natural ventilation in a “dead” room.

A properly selected and installed ventilation system already guarantees by 50% that a windowless room will become a comfortable living space.

How does Breezer keep the air in your home fresh and clean?

The freezer is a compact unit of supply air, equipped with a filter system and flow-through heating. In order to install it, you need to make a through hole in the wall, and then install the device itself on it. The principle of its operation is quite simple - an electric fan provides air flow from the street, and a filter system ensures deep cleaning of dust, pollen, odors, and microorganisms. In winter, the air flow is heated to a comfortable temperature, which eliminates drafts. The result of using the Tion o2 breather is fresh and heated air in your home.

With the Tion o2 freezer, you don't need to open the windows at all - you have a constant source of clean air in your home. All microorganisms, vapors, allergens and odors remain on the filters, and you can breathe with your chest free from drafts, cold and dust.

The maximum noise level when the freezer is operating at the second speed is 40 dB. It should be noted that the freezer emits so-called “white noise”, with a constant frequency, to which the human ear gets used to after 10 minutes and stops noticing it.

MagicAir is a new level of comfort in creating an ideal microclimate. This is a high-tech device that evaluates the current air parameters in your home and provides autonomous control of air conditioners.

This problem can be solved in three simple steps:

1. The first step is to install a compact and “smart” MAC air diffuser Tion O2, which will provide a constant supply of fresh air, its thorough cleaning and heating.
2. The second is to connect and place a MagicAir station, which will establish a wireless connection to your freezer via the Internet. Now you can receive air quality data on your smartphone and remotely control the microclimate in your home.
3. Third, set your own CO2 levels and the cooler will automatically maintain the optimal ventilation level for you.

Ready-made solutions for your home

To simplify the ventilation of rooms without windows, forced ventilation devices were invented. Such devices are called aerogivers; they are easily mounted on a wall inside a room. Although air vents are expensive and can only provide fresh air in the room where they are installed, they are an excellent ready-made solution for organizing air exchange.

A good ready-made solution for apartments and houses with blind rooms is split systems with climate control.

Aerogivers

Aerogivers consist of devices that allow the flow of clean air into the room; filters to clean the air from dust, harmful impurities, and allergens; recuperators and dryers.

It is easy to install the airgiver in an apartment yourself; to do this, you will need to carefully study the instructions and prepare the device for making a hole in the wall.

The main advantage of such devices: the room is ventilated around the clock, but there are no unpleasant odors from the street in the room. Clean air enters the room already heated, because... Most of these devices are equipped with a recuperator.

When installed correctly, aerogivers do not create additional noise in the room, so they can be installed even in a nursery.

Air conditioner

Almost all modern air conditioners are made in such a way that they provide a flow of fresh air into the apartment from the street, and do not simply dehumidify the air inside the room. Therefore, split systems with climate control are a complete replacement for natural ventilation in rooms without windows.

Some air conditioners can additionally enrich the air with ions, warm it up and clean it of allergens.

But split systems with climate control capabilities are installed point-by-point and are not able to ensure the correct movement of air masses throughout the apartment. Therefore, to ensure a comfortable microclimate throughout the apartment, it will be necessary to install air conditioners in each room.

How much air do you need to provide?

It is important to calculate the amount of air needed for the room. The calculation should be based on the following factors:

• how many people and how often will they be in the room;
• what exactly will the room be used for (if for relaxation and quiet entertainment, then you can get by with a reserve of 30 m³/h per person, if heavy physical work is performed, 60);
• what conditions are specific to a given room (for example, if it is a basement, the likelihood of moisture getting inside is greater than in an above-ground room);
• whether harmful substances will be released (for example, if a windowless room is used as a workshop where painting work will be carried out).

In most cases, a simple calculation can be made. This means about 30 cubic meters of air per hour per person indoors. This is a minimum value, but in general it is advisable to raise it to 32-35 cubic meters of air per hour.

Finish: ceiling

Proper finishing of the ceiling will make the room more comfortable and add height to it. A light coating will relieve the visitor of the oppressive feeling of a hanging ceiling.

It is permissible to use suspended ceilings and plasterboard structures to create multi-level lighting. This technique will help to visually lift the ceiling and smooth out the boundary between it and the wall.

Walls

Light paint or wallpaper is usually used to cover the walls. The wallpaper may have a small, discreet pattern.

The technique of one contrasting wall is often used, on which photo wallpaper, wallpaper of a contrasting color, or mirrors are placed.

You can use striped wallpaper. Moreover, horizontal stripes increase the width of the room, and vertical stripes increase the height.

Floor

It is preferable to use light brown flooring. Laminate or parquet can be laid diagonally, which will help visually expand the space.

How to check the draft level in a room?

Before installing ventilation systems, it is necessary to know the level of sediment, for which a strip of paper 2 cm wide is sufficient. It is exposed to wind on both sides. However, it is not recommended to test air circulation using flammable devices due to the risk of explosion. A sheet of paper is applied to the ventilation grille, in the kitchen or bathroom. Then you have a few minutes to observe his behavior.

The more the paper oscillates, the better the ventilation works. If it remains stationary, it needs to be upgraded. If one person lives in a room without windows, about 60 watts of heat is generated. If there is a natural ventilation system, holes are made in the lower part of the wall. If there is access from the outside, then a ventilation hole is installed.

Modern ventilation in closed spaces can work very effectively if it is properly designed taking into account all the features.

No. 11. Light colors

The ability to reflect light varies among different colors . For example, dark, saturated shades absorb a significant portion of the radiation, while light shades, on the contrary, mostly reflect it. White works best in this regard , which is why designers fell in love with it, actively using it in all small rooms. It is better to choose it for the ceiling. If it doesn’t quite fit into your interior plans, then choose another light shade. It is important that the ceiling is lighter than the walls.

unobtrusive light and pastel shades of for walls and furniture . Beige, cream, light blue and light peach will make the room cozy, create a feeling of open space and much-desired natural light. Do not forget about shiny finishing materials: metallic wallpaper, glossy plaster, etc.

To prevent the interior of the room from being completely boring, it can be complemented with several bright accessories. Natural shades are preferred. Two or three bright colors will be enough - otherwise you can overload the room.

How to organize

There is one universal rule in solving the problem of ventilation in a room without windows. Rooms with heavily polluted air must be equipped with an exhaust device. These include: bathrooms, kitchens.

For potentially clean rooms, it is sufficient to ensure good air flow through ventilation grilles or small gaps under internal doors.

The first thing that can bring air into a windowless room is a small gap under the door. Special overflow grilles built into the door are another option.

They can also be installed at the bottom of the wall. If there is insufficient air exchange, you can also use exhaust fans.

In the dressing room

Cabinets are usually installed in small rooms without windows. In this case, you cannot count on air flow through the gaps:

• the gap between the bottom edge of the door and the floor;
• special design of cabinet doors (with slots or plug-in ventilation grilles);
• holes in the walls that are located no further than 20-30 cm from the floor (you can go down, just above the baseboard);
• technological gaps arising from the construction of partitions;
• in private houses - through a ventilation hole in the floor (from the lower floor or from the basement, if there is normal humidity).

The dimensions of the air intakes depend on the cubic capacity of the room and the speed of the air masses. Standards for storage cabinets require one air change. For example, if your closet measures 1.5*2.0*2.8 (width, length, height), then its volume (obtained by multiplying all numbers) is 8.4 cubic meters. Within one hour, 8.4 cubic meters of air must be “pumped” to maintain a normal atmosphere. Thus, ventilation of the dressing room will prevent the formation of foreign odors.

With proper ventilation of the apartment, an air intake of 100*100 mm is sufficient for this. The cross section - round, square, rectangular - does not matter. The main thing is that its area remains the same or larger. And, as a rule, this parameter is calculated or found in accordance with the table. However, the tables show much larger volumes.

But closet ventilation will work well as long as there is an exhaust duct. It could be a similar grate in the wall. It should be placed on the wall opposite the air intake, closer to the ceiling. You should aim to keep these holes as far apart as possible so that the air flow covers as much of an area as possible.

If the air intake is made in the door, and the door is located in the middle of the width of the room, then it is worth installing two exhaust grilles - on the right and on the left, at a distance of 15-25 cm from the corners.

Where should the vents be placed? At best, to the ventilation duct. A possible option is outside, if one or more wardrobe walls face the outside. In this case, the air supply can be vented outside and the exhaust into the ventilation system or into adjacent rooms.

Closet

A common option both in an apartment and in a house is instead of installing regular wardrobes and/or chests of drawers.

The location of the air exchange depends on the number of walls (partitions) in the cabinet and the size of the cabinet. Typically, such cabinets are not huge: most of them are “simple” cabinets with shelves and drawers, simply not free-standing, but “attached” to the wall.

Let's consider how it can be ventilated in accordance with various schemes:

1. If there is only one partition in the closet - the front one, and on the other 3 sides there are walls of the apartment bordering the living rooms. Simply cut inlet holes at the bottom and top of the baffle.
2. If the wardrobe has only a partition, then on the other 3 sides there are living walls, one of which borders the bathroom/kitchen. In this case, a perimeter grille can be cut in the lower partition (through which air from the room will be sucked into the cabinet). To remove air, you can drill a hole in the wall between the cabinet and the kitchen/bathroom and cover it with a grill. This option is not the most convenient: in the future, you may want to change the layout and move the cabinet, but the hole in the wall will remain in the same place.
3. If the cabinet has 2 or more compartments. In this case, a bypass grille is cut into the partition located closer to the window from below. The second bypass grille is cut from above (closer to the ceiling) in the partition, which is closer to the door.

Generally speaking, venting in cabinets is not necessary—in most cases, simply cutting overflow holes in the doors will do the trick.

Separate room with window

The simplest option is to do nothing: all conditions have already been met.

In this case, air flow can be ensured in the following ways:

1. Leave the window cracked. Suitable if the window sash can be fixed in several positions and if there is no source of loud noises or odors under the window.
2. Install the window comb and keep the window tilted. Suitable when the window sash does not have its own methods of fastening. As for the cost: the simplest comb can cost up to 1000 rubles.
3. Install windows in micro ventilation mode (if the apartment is under renovation, or it’s time to replace the windows). This option is so much better than the previous ones that the window does not need to be opened all the time. This means that sounds and smells from the street, insects, rain or snow will not penetrate it.
4. Install the window valve. Suitable in cases where it is impossible to leave the window open (for example, due to noise) and there is no ventilation mode. The disadvantage is that not everyone can install the valve themselves. The product itself will cost about 3-5 thousand (depending on the model), installation by professionals can cost about the same.
5. Install a window fan. If you have a large closet or will store expensive items in it, then this option is worth considering. Natural ventilation (all of the above methods indicate it) has an unstable power, while a fan can maintain constant air exchange.

There should be a break under the cabinet door to allow air to flow in and out of the cabinet. If this is not possible, a bypass grille (or valve, for example Domvent) can be installed in the door leaf.

A more expensive and somewhat unknown option: you can install a miniature Aeromat unit in the window. Inside the rectangular housing there are fans that supply both supply and exhaust air. This means that they can freshen the air even in a sealed room. The disadvantage is that such products cost tens of thousands of rubles, and only a specialist can install them.

Separate room without window, street through the wall

Organizing a ventilation system in such a room will itself be more difficult than if the room had a window. However, there are many possibilities for implementation.

An example of a ventilation system for this layout: 1 – air intake through the gap under the door; 2 – connection point for the exhaust fan

In the previous paragraph, we looked at a scheme in which air enters the dressing room only from the outside - after all, in a room with a window this is the simplest option. If you don't have a window, you'll still need to make a hole in the wall for ventilation. Can be used for both inputs and outputs.

First let's look at how air is supplied through the wall. To do this, drill a hole in it and insert a wall valve. This option is the simplest and cheapest (the valve itself can be bought for 3-5 thousand, installation will cost the same).

There is another option, but it is not feasible: a power supply is placed instead of the valve. This device is more expensive: such equipment will cost more than 10 thousand rubles. The main thing: the units have a large air capacity - which is not needed for a small room, for example, a dressing room.

As mentioned above, you can arrange for the exhaust pipe to be removed from the cabinet rather than brought in from it. In this case, drill a hole in the wall and insert an exhaust fan (which will not blow into the room, but from outside). This is a good solution if the dressing room is located far from the kitchen/toilet.

The general rule for both methods is that there must be airflow between the closet and the hallway (or room). This requires either a gap under the door or a bypass grille in the door leaf.

Separate room, surrounded by other rooms

The most inconvenient and difficult option to implement. Such layouts are common: owners often create their dressing rooms in closets that are located “inside” the apartments. Additionally, when houses are built with walk-in closets, they are typically built to this type of plan.

In this case, it will be more difficult to complete the task, especially on your own (without specialists). There are several solution schemes:

1. A hole is made in the wall bordering the living room with a window - if the room is further from the kitchen/bathroom than the dressing room - and covered with bars. Air will pass through it. The air is exhausted through the gap under the door into the hallway and then into the nearest ventilation pipe or eaves. If there is no gap, a bypass grille is installed in the door.
2. If there is a kitchen or bathroom opposite a closet or room with a hood, a hole is made in this wall and covered with a grill. The air will be exhaled through this hole. Fresh air will enter through the gap under the door grille/overflow grille.
3. If the house/apartment is undergoing renovation and suspended ceilings are installed, you can organize a system of air ducts through which air will be taken from each room. In this case, a separate line is drawn to the cabinet. The influx of fresh air will pass through the gap under the door. The exhaust duct can go either to the nearest hood (as in the photo above), or through the wall to the outside (in this case, an exhaust fan is placed in the duct).

Kitchen

It is important that the ventilation system is equipped with a ventilation duct. This will act as an exhaust system and the used air will be removed through it. Another option is to exhaust air through a kitchen hood (which can be directed into a ventilation shaft or directly outside through a wall or duct).

Air will come from other rooms either through the cracks under the door or through the overflow grilles (if there are no cracks).

In this case, it is necessary to check the draft of the ventilation shaft. To do this, take a strip of thin paper and apply it to the ventilation grill.

If the paper is attracted, the air roller is working properly. If it doesn't work or has very little pull, it means the air roller is either not working at all or not working well (it may be clogged and needs to be cleaned). If for some reason cleaning is impossible now, it makes sense to install an exhaust fan in the wall with access directly to the street.

The fan's performance must be capable of completely extracting an amount of air equal to the number of people living in the apartment, multiplied by 30. For example, if 3 people live in an apartment, then the fan must exhaust at least 90 cubic meters of air per hour.

Ventilation in a blind bedroom without a window

If there were no windows when the bedroom was built, there is one reliable way to ensure proper air exchange.

For this purpose, a mandatory type system will be installed, which will consist of:

• several fans;
• air heating device;
• supply air filters;
• ventilation grates;
• air channels.

Installing a ventilation system in a bedroom without a window is done by creating several holes in opposite walls where the above equipment is installed.

The completed system must pass incoming air through filters, heat it, and release it through vents.

In a room that borders the street

There is an effective option, which is possible if the room bordering the street through the wall is not dirty (kitchen or bathroom).

In this case, it is recommended to create an air flow in one of three ways:

• using a power supply;
• use of wall dampers for air supply;
• from a fan installed in the fan.

To ventilate the air, it is necessary to create an inlet inside the living space through grates in the wall or doorway so that air can freely flow into the room in which the hood is installed.

If the room borders the street through at least one wall, then a specially designed hole with a fan is sufficient for normal air exchange.

In this case, air is removed outside while air is brought in from other rooms.

In a room that does not border the street

The first option is to lay a separate ventilation duct. This is possible if the building has at least one air exchange system that supplies or extracts air masses.

In addition to the existing system, a ventilation system must be installed (if there is an input, sort the output and vice versa).

If the room is located between the supply room and a room equipped with an exhaust hood, then the air flow will pass through several openings with special grilles (which can be supplemented with fans).

This option is suitable in cases where intensive air exchange is not required. Usually the rooms are small in size. A necessary condition is the filtration of incoming air.

In large rooms or rooms that are very far from the ventilation shaft, it is necessary to install separate air ducts to provide supply and exhaust air for the exhaust. In this case, a fan must be installed for each of them.

Ventilating a room with plastic windows

Plastic windows are beautiful and practical. They do not allow noise from the street to pass through, and in winter they reliably protect from the cold. But this also has a clear disadvantage. They interfere with natural air exchange. Therefore, a room with plastic windows needs additional supply equipment.

Plastic windows are practical and popular, but they interfere with natural air exchange

All plastic windows have a micro-ventilation function. But it does not solve the ventilation problem. In winter, you cannot open the window, because frosty air will enter. The air supply cannot be controlled; drafts are created.

The ideal option for a room with a plastic window are supply valves. It is better to give preference to wall units: you can install filters in them and make the air warm or cool.

If natural exhaust ventilation in the apartment does not work well, an exhaust fan is installed in the room

It is important to ensure that the room is connected to other rooms - through cracks in doors or bars

You can ensure the normal operation of the supply and exhaust air exchange system in any room yourself. Selecting equipment is easy. To create a normal microclimate in the apartment, air conditioners with air flow, kitchen hoods, fans and valves are installed.

The common house ventilation shaft must be cleaned to maintain its normal operation. It is forbidden to do this on your own, so you need to call specialists.

Operating principle of the device:

1. Dust and recycled air accumulate inside the room. It is removed from the room through an indoor duct exhaust system.
2. Contaminated air masses enter the roof and are removed to the street using a device - a deflector.
3. To bring fresh air into the room, the following devices are used: air masses enter the intake container located on the street. They pass through several stages of filtration and are purified.
4. Clean air is pumped into the room through air ducts.

Modern air circulation devices are equipped with additional filters to increase operating efficiency. Thus, they may contain useful substances and minerals that have a beneficial effect on health. Can help humidify or dry a room. They also produce filters that prevent insects from entering the room.

Has the apartment become too stuffy, the windows started to fog up, and the characteristic kitchen and toilet odors remain in the rooms for a long time? The cause of all troubles is the same - insufficient ventilation.

Ventilation in the apartment with your own hands

This problem requires an urgent solution. Otherwise, you risk saying goodbye to wallpaper, furniture and other apartment furnishings, which will simply begin to rot in conditions of excessive humidity.

You can install an effective and reliable ventilation system in your apartment on your own. It is absolutely not necessary to have any specialized skills to perform such work - you just need to have basic knowledge of carrying out the relevant activities and be able to work with basic construction tools.

Poor ventilation in the apartment

Poor ventilation

Read the presented guide, do everything in accordance with the recommendations given, and you will forever forget about the problems that arise when the ventilation of the apartment is insufficient.

How to make ventilation indoors below ground level

If even a small part of the basement is above ground level, an air intake opening must be made in the basement. Exhaust gases are discharged through the manifold ventilation shaft. If there is no ventilation shaft, the exhaust air is directed through the wall opposite the suction opening. Grilles are installed on ventilation openings to protect against rodents, precipitation and dirt.

If the basement is completely underground, then the supply and exhaust air ducts pass through the basement.

Fans are installed inside air ducts for more efficient air exchange.

Ways to simulate windows

A well-designed lighting system almost completely solves the problem of lack of sunlight in a bedroom without a window. However, experts prefer to show their imagination and create the illusion of the presence of windows in the bedroom. Why is window imitation necessary:

• A positive effect on a person’s psychological state, because a confined space has a depressing effect on many.
• The ability to correct and disguise some wall imperfections.
• Visual increase in space.
• An unusual detail that will decorate the room.

An artificial window can be of any shape and size; for greater realism, you can insert glass, a liquid crystal screen or photo wallpaper with a realistic landscape.

What are the options for artificial windows:

• Photo wallpaper. An image of an open window or exit to a balcony, behind which a landscape with a noticeable perspective is drawn. It is advisable to completely cover one of the walls with photo wallpaper, and use interior details that can increase the degree of realism of the picture.

Diameter of ventilation channels

It is not enough to punch a through hole of any size: proceed on the basis that 1 m2 of hole should have a diameter of 1.5 cm; if the room is 20 meters, then you need to punch a hole with a diameter of 20 cm.

For ventilation to work effectively and not interfere, the hole should be located slightly above floor level. The air duct should extend 40 mm outwards. It should be directed upward: this ensures optimal supply and exhaust of polluted air from the room. To prevent dirt from entering the air duct, it is protected by a special roof and mesh.

Ventilation in a room without a window is made in the form of an air duct with perforations on the walls, which can be placed vertically or horizontally. This device is necessary for uniform distribution of air in the room. To ensure the exhaust of used air, it is necessary to install a hood. Installed at the top of the wall at a distance of about 50 cm from the ceiling. In private houses, the exhaust pipe must be at least 30 cm above the roof. In an apartment it can be placed along the wall at the same height. In both cases, the pipe should be directed upward.

Ventilation in a windowless room will be more effective if the exhaust pipe is also equipped with a condensate separator and grille. This will prevent it from clogging with various impurities.

To effectively suck air into the duct, you must use a fan of sufficient power. Outside air enters the room, first passing through a filter.

Kitchen hoods

The hood is an important element of ventilation in the kitchen. Today, the hood is a fashion accessory. It rids the kitchen atmosphere of moisture, unpleasant odors, gas and grease fumes.

Today, kitchen hoods perform not only practical, but also aesthetic functions.

Based on the principle of operation, there are two types of hoods:

1. Active. They are connected to a common house ventilation shaft or lead directly to the street.
2. Passive. Serves as a filter. They absorb air from the kitchen, clean it of impurities and release it back. They are not connected to ventilation.

Hoods vary in power. If the kitchen is large and food is prepared frequently and in large quantities, you need to purchase powerful equipment. The hood is powered by power. You can turn it on and off yourself and adjust the traction.

Installation of a wall ventilation valve

Such a dressing room layout, where only one room is adjacent, will not allow connecting supply and exhaust ventilation. Currently, this problem can be solved by installing a power valve in the wall.

This device is a plastic pipe through which air from the street flows directly into the locker room.

It is worth remembering that installing a ventilation valve in the wall interferes with the architectural appearance of the building. However, this activity, like the installation of air conditioners, is currently not regulated by law.

The inlet valve consists of the following components:

• external ventilation grille, which prevents moisture, dirt, large solids and insects from entering the structure;
• a filter that cleans the outside air of small particles, directing the purified air into the locker rooms;
• a valve that allows you to continuously regulate the air flow in the room.

More expensive models have a noise reduction system, automatic humidity control, and a special design where air coming from the street through a valve enters the radiator, where it is heated to room temperature, and then enters the dressing room.

The installation of a wall vent must be carried out by a professional as the external part will be installed at a certain height. Work at height must be carried out in compliance with all safety requirements.

What happens?

Ventilation for dressing rooms can be of various types. Let's look at some of them individually.

• Forced ventilation. This option is used when natural air circulation becomes insufficient. However, it is better to organize such a system already at the stage of designing a house. In this case, it will be necessary to bring a chimney from the common system. It will also be necessary to install a special fan of the required power.
• Doors with ventilation. Such products are doors equipped with special ventilation grilles. They can be of different sizes. The mesh itself can be installed from below and from above. These products allow you to control the level of humidity and temperature differences inside the room, provide good circulation of air flow, and also remove toxic components from the room. The ventilation holes themselves can be round, oval or square. Decorative rings are usually additionally attached to such structures. Doors often have not only aesthetic qualities, but also increase the level of sound insulation in the dressing room.
• Design with air intake system. This option is most suitable for dressing rooms that do not have window openings. In this case, several small horizontal holes are created at the border with the adjacent room where the system is already installed.
• Combined ventilation. This option is used when the dressing room is combined with the rest of the living spaces in the house. But in such rooms the system must be strong enough. Sometimes several powerful fans are used simultaneously, as well as several filtering devices. Sometimes special ventilation shafts are also used.

Without external wall

Leaving a room's door open to allow fresh air in from another room is a simple solution, but not always ideal. For example, if a windowless room is being used as a workshop, you will need a locked door to keep children and pets away from fragile parts or dangerous tools. A door with bars at the bottom or ventilation holes in the wall can help in this situation.

If it is not possible to provide ventilation for each room, then the amount of air entering the ventilated rooms must be sufficient for the volume of all rooms.

When installing ventilation during reconstruction or repair, one of the walls in a room without windows is not completely closed, i.e. there remains 10-20 cm between the top of the wall and the ceiling. Through this hole, air movement will be directed towards the cornice.

If your home has a ventilation system, you can try running a separate duct into the room. This option is more suitable for rooms that have not yet been decorated, otherwise installing additional air ducts in the ventilation system may ruin the renovation.

To ensure silence

When installing regular grilles on both opposite walls in the locker room, noise will penetrate through them. Clothes and space will dampen them a little, but some sounds will be heard. If you don't mind this prospect, then that's okay. But if you want silence, you can install special grilles or valves in the openings.

They barely block air flow, but they block light and noise. These grilles aren't cheap, but there's no other way to ensure that cabinet ventilation is efficient and sound-proof.

Installation nuances

Before carrying out ventilation in the dressing room itself, you need to know the features of its location, as well as some rules for its installation. Including:

1. The need to choose a place to supply fresh air. The main condition is that the wall must border the street.
2. Select a location to install the chimney. It is best to use the wall opposite the air intake (if it also borders the street). The air duct can also be made in the gap between the door and the floor.
3. Use of exhaust and intake valves or grilles with adjustable air flow.

Natural ventilation of dressing rooms is installed in pre-prepared openings in the walls.

The exhaust and discharge valves are mounted in designated locations opposite each other. Some models of these units are equipped with mechanical retaining washers. If there are none, attach the flaps or grilles using glue or caulk.

With the correct choice of the position of the socket windows and power supply, the device will work efficiently. In addition, the simplicity of this design allows you to supplement the ventilation system with a fan. With this device, the air flow moving in and out of the locker room will be more efficient.
