The correct organization of air exchange in the bathhouse is a serious task that requires a professional approach. It is not enough to build a bathhouse, complete interior decoration, install heating equipment and furniture. It is important to ensure effective ventilation of the bath rooms, to form a favorable microclimate that allows you to enjoy water procedures and contributes to a long service life of the decoration, as well as the entire structure.

Bath ventilation is a guarantee of comfort

Relaxation in the sauna will be a pleasure if it is easy and comfortable to breathe in the room.

In a steam room, the air temperature is very high, so if there is no ventilation in it, you can suffocate or get heatstroke.

If the correct air exchange is disturbed or if there is no ventilation at all, it will be difficult to breathe in the steam room and it will be impossible to stay for a long time.

The ventilation system allows to create a comfortable microclimate, which ensures the supply of oxygen-saturated air and the removal of "spent" air masses.

The traditional layout of the bath complex provides for a dressing room, a washing compartment, as well as a relaxation room, and everywhere it is important to ensure effective air circulation.

Favorable microclimate in the relaxation room will allow you to relax after visiting the steam room

The increased concentration of moisture is not as enjoyable as in the process water treatments and during rest. The human body is sensitive to a lack of oxygen and high humidity.

The conclusion is unambiguous: in the bath, you need to make good ventilation so that it is pleasant and comfortable not only to bathe, but also to relax in it.

Disruption of air circulation or lack of ventilation causes:

Types and principles of ventilation arrangement

For any type of bath (Russian, Finnish sauna, Turkish hamam) ventilation is provided, which can be carried out in different ways.

Natural air exchange

The principle of the formation of convection air flows is based on the temperature and air pressure drop from the street side and inside the bathhouse.

The temperature difference promotes the movement of air currents

Maximum air exchange efficiency is achieved due to the correct location of the supply and exhaust ventilation lines.

The traditional arrangement of air ducts is used to ventilate the premises of the Russian bath and sauna. The supply air duct is located at a distance of 0.2–0.3 meters from the floor, and the exhaust pipe is located at the same distance from the ceiling. Control dampers in the room should be provided to optimize air flow and provide a comfortable temperature regime.

The damper allows you to regulate the flow of air into the room

Natural ventilation should provide air exchange, keeping the room temperature and not creating discomfort during rest. The advantages of natural air exchange are simplicity and low costs associated with the absence of the need to purchase expensive equipment.

Combined option

The method of organizing the movement of air masses in a room using a fan that circulates is called combined. At the same time, there is no regularity in the location of the ventilation ducts.

The ventilation scheme is determined individually and provides for the installation of an outlet and a duct equipped with a fan, which is mounted on the supply line or exhaust duct and creates the required pressure drop.

Providing air exchange in the premises of the bath using the combined method is convenient and economically justified.

Forced circulation

The forced air exchange system is also called mechanical. The system is equipped with automation elements that control the temperature regime, regulate humidity and the intensity of circulation of air masses.

Forced ventilation ensures maximum comfort.

The increased costs associated with the purchase and installation of equipment, as well as the complexity of maintenance, limit the use of a mechanical air exchange system in small bath rooms.

For rooms with an increased area, forced circulation is used if natural or combined air exchange is not effective.

If the premises of the baths have big sizes, you need to arrange in them forced ventilation

The following types of mechanical ventilation are used:

1. Exhaust, equipped with a filter element and a fan. This type of ventilation ensures effective removal unpleasant odors and polluted air masses from rooms with swimming pools, washing rooms and recreation areas. Application exhaust system needs to ensure the flow fresh air required to compensate for the vacuum generated by the fan.
2. Supply air, which supplies oxygen-rich air. Saturated with vapors Due to the increased pressure, air masses leave the room through the ventilation ducts, as well as through the existing gaps in doors and windows. Combining the supply line with a heating device allows fresh heated air to be supplied. The design of the supply air exchange is more complex.
3. Supply and exhaust, combining the principle of supply and exhaust ventilation. Using this ventilation principle in the sauna room requires preliminary execution calculations. The circulation rate is determined based on the fact that the volume of the incoming air must correspond to the volume of the displaced one. In order to prevent the penetration of air from the bathroom into the recreation area, the ratio is deliberately violated. This makes it possible to form a reduced pressure in the toilet room and direct additional flows into it.

Air exchange organization principles

When planning a ventilation device, be guided by the following recommendations:

It is important to correctly calculate the area of ​​the ventilation ducts. The section of the vent and the air duct is determined by the size of the steam room, for each cubic meter of volume of which it is necessary to provide 24 cm 2 of the area of ​​the ventilation duct.

For a comfortable stay in a heated steam room, provide the possibility of more than five times the air exchange (the air in the steam room must be renewed 5 times per hour). The layout of the supply duct and exhaust duct, as well as their number, should facilitate easy circulation of the masses in the steam room.

Effective air exchange will increase the service life wooden floors... To ensure it, you must:

The correct ventilation device will allow you to fully enjoy the steam room and get great pleasure from the sauna relaxation.

How to make ventilation in the bath with your own hands

The organization of air circulation in each room has individual characteristics.

Dressing room ventilation

The tambour room or dressing room is used as a changing room. The compartment is located away from areas with high humidity and temperature.

The ventilated changing room will always be dry and comfortable

The use of the front door promotes the flow of fresh air and reliable ventilation of the changing room.

The location of a ventilation grill with a valve in the upper part of the wall will ensure natural air exchange and control the volume of incoming air masses.

When constructing a building, a ventilation hole must be provided. If there is no air channel, then you must make it yourself:

Air exchange in the washroom

The washing compartment, in which the shower is installed, is ventilated due to the natural circulation of air flows moving from rooms with high humidity to ventilation vents or small vents.

The easiest way to ventilate the washroom is by using a window.

To improve ventilation efficiency and reduce humidity, it is advisable to equip the shower room with an exhaust fan.

Install the fan according to the following algorithm:

For ventilation of the washing room, use fans with an operating voltage of 220 volts, with a low power - 20–100 W.

When purchasing a fan, pay attention to the possibility of the device operating at high temperature and humidity, as well as the degree of protection, which should not be lower than IP44.

Organization of air circulation in the steam room

For ventilation of the steam room, make 2–3 ducts intended for air exchange. One line will provide fresh air, and the rest will allow the exhaust air masses to leave the room without hindrance.

The increased size of the exhaust duct allows for faster ventilation of the steam room

Place the channels according to one of the proposed ventilation schemes.

The intensity of air exchange depends on the location and size ratio of the supply and exhaust ducts.

Making holes during the construction phase will preserve the integrity of the finishing materials and facilitate work.

The area of ​​the inlet line must correspond to the size of the outlet duct. However, a more efficient convection flow can be achieved by making a slight increase in the diameter of the suction line.

A prerequisite is the installation of adjustable valves that allow you to change the intensity of air exchange.

In a wooden bath, it is better to make the valve from the same wood that was used for interior decoration

Implementation of measures for the arrangement of canals is not difficult:

Creating a microclimate in the recreation room

Comfortable temperature conditions and optimal air circulation in the relaxation room are achieved through natural air exchange.

Air duct in the upper part of the wall ensures sufficient fresh air flow

It is important to provide an air duct equipped with an adjustable damper or ventilation valve... This will, if necessary, increase the intensity of the movement of air masses.

To organize the access of fresh air, instead of a ventilation duct, you can use a window

Drilling a hole and installing the valve is easy.

Video: making a ventilation valve

Variants and layouts of ventilation ducts

In the bath you can use different variants the location of ventilation communications, providing for natural air circulation and the use of a fan.

Different variants of the ventilation device differ in the location of the channels, but provide high efficiency of air exchange

One of the proposed schemes of natural air exchange, which provides for the following options for the placement of ventilation ducts, will ensure a comfortable adoption of bath procedures:

To achieve a favorable temperature regime and comfortable humidity, air exchange schemes provide for the installation of a fan:

Remember that the determination of the performance of the fan unit is made by multiplying the volume of the steam room by the coefficient of air exchange.

For example, to determine the required air exchange in a steam room with an area of ​​10 m 2 and a height of 2 meters, it is necessary to multiply the volume by the air exchange coefficient equal to 5 (we have already said above that the air in the steam room must be completely renewed 5 times per hour). The obtained value of the fan performance is 10 x 2x 5 = 100 m 3 / h.

Heated air ventilation

Air exchange with simultaneous heating of the incoming air is carried out in the bath in different ways. They involve the use of a fan or natural air exchange. For example, by placing certain air channels in the immediate vicinity of a hot furnace, it is possible to simultaneously inflow oxygen-saturated air and increase its temperature due to the heated surface of the heating unit.

In order to create a favorable temperature regime, comfortable humidity and smooth heating of the incoming air masses, it is necessary to use plugs or slide dampers located on the air lines. Ventilation while simultaneously heating the air is a rather difficult task.

Each heating unit has its own individual "character". Only as a result of experiments, it is possible to select the optimal air exchange mode and ensure a comfortable temperature in the bath room.

To increase the temperature of the incoming air masses, you can use an electric heater that heats the air entering the room. This is another option for air ventilation with simultaneous heating.

The air entering through the ventilation ducts can be preheated by an air heater

Power electric heater is selected experimentally.

The electrical equipment used in the premises of the bath must withstand high temperatures and humidity, be reliably grounded and have a protection class of at least IP44.

Combining air ventilation with heating allows you to create comfortable conditions for vacationers, as well as reduce the costs associated with heating a room using heating equipment.

Acquaintance with the principles of organizing the correct air circulation in the steam room, as well as the rest of the rooms of the sauna and bath, will allow you to independently organize the process of effective air exchange. It is important to correctly calculate the dimensions of the air lines and to optimally place the inlets of the channels in the premises. Remember that the design of the heating device and the chimney additionally affects the degree of air circulation. By following the recommendations, you can avoid mistakes and enjoy the wellness procedures in the sauna with a comfortable microclimate.

For a long time, people believed that the bath is able to heal the body. It is not for nothing that a saying has appeared among the people: "The bathhouse soars, the bathhouse rules, the bathhouse will correct everything." To really get a charge of vivacity and health, it is necessary to create the most favorable microclimate for this with a sufficient oxygen content in it. This is what the ventilation in the steam room serves, where the air must be renewed at least 2 times during each hour. When we talk about a bath, it also means a steam room.

The quality of taking bath procedures and our well-being directly depend on whether the ventilation scheme in the steam room is performed correctly. Before we look at how to make ventilation in the steam room, let's take a look at its functions.

Functions of natural ventilation in the steam room

The bathhouse needs ventilation, because it has 3 main functions:

1. Steam room oxygenation.
2. Creation of optimal bath processes for steam and air exchange control.
3. Drying the bath after washing to prevent mold and mildew from damaging wooden structures.

For bathers to breathe easily, a constant supply of fresh air is required. Many argue that ventilation is unnecessary. after washing, ventilate the bath through the door and window.

In the human body, at the moment of vaping, the process of oxygen exchange in the blood increases several times. For one visit to the steam room (up to 2 hours or more), an adult produces 0.5-1.5 liters of sweat, which is a concentrated toxin. Without an influx of fresh air, we are poisoned by the products of our own vital activity. An air mixture that is low in oxygen and high in carbon dioxide can cause headaches, nausea, dizziness, and lethargy. People perceive this as intolerance to the bath, and do not realize that they themselves have created such conditions. The reason is that there is no ventilation in the steam room.

How are steam modes created? In order for the air flow to quickly heat up, it is introduced at the bottom of the oven, from which it heats up and, mixing with steam, rises to the ceiling and to the steam zone.

A layer of steam is created there, which, when cooled, begins to settle in the form of condensate. On the wall opposite the stove, opposite to the side below, under the bath shelf, a hole is made for the exhaust air to escape. Due to internal circulation, fresh air is actively mixed and unnecessary air is removed. Valves are installed on the channels in order to correct the air exchange in the steam room. This is how the steam is controlled, and the bath procedures take place in more comfortable conditions.

On the wall opposite to the inlet, in the upper part, another exhaust hole is made, which is closed for the period of heating and washing. Top exhaust not for steam operation. It is only needed to dry the bath after washing. After taking bath procedures, it is necessary to open both the upper hole and the lower one in order to thoroughly dry the room.

Many are mistaken, claiming that you can dry a bath with an oven at closed doors and windows. This is an illusion. In the absence of air exchange, it will not be possible to dry the bath well. When heated, air is able to retain a lot of water (steam). When it cools down, everything happens the other way around: the air cannot hold much moisture and begins to throw it out in the form of dew. As a result, a lot of dampness will remain in the bath. With organized ventilation, with each new stream, excess moisture is carried out into the street. Any steel furnace can handle this, because the cooling process takes up to 3 hours.

Steam room ventilation through the foundation

The design of the building affects the choice of the type of ventilation system.

An example of ventilation of a steam room through the foundation

Previously, there was no ventilation in chopped baths, or it was used in its simplest form. The air from the steam room came out through the blower of the stove, which was installed here. Fresh air was supplied through a door ajar 5 mm. The design of the bath was as follows: a steam room, a washing room and an oven in one room.

In order for the stove to function as a cooker hood, it must be installed so that the blower is below the floorboards. It should be borne in mind that ventilation through the furnace blower takes place only during the period of fire burning in the furnace. If you are using stoves with short-term operation, you cannot do without the use of an improved ventilation system.

Here is another diagram that will help those who have a metal stove. The ventilation of the steam room is based on the burning stove itself. It should ventilate not only the bath, but the entire foundation. Bad air with an unpleasant smell usually accumulates under the bath, if everything is not arranged correctly. A vent made in the foundation promotes the flow of air under the floor.

Ventilated underfloor

In the heating (heating) mode of the bath, the air circulates between the washing room, the steam room and the space under the common floor. To do this, a window with a latch is made in the partition between the steam room and the sink to regulate the ventilation mode.

From the chimney of the stove, there is a draft to the surface. For her, air comes from all possible cracks.

By metal pipe with a diameter of 115 mm, 5-10 l / s of flue gases pass, which is equivalent to the intake air of the furnace - 300-600 l / min, and this is 2-3 barrels of air in 1 min, the furnace pumps out into the chimney.

Therefore, if your stove cheerfully smokes with a chimney, it means that it absorbs the same amount of air through the blower from the bath, while giving off a colossal amount of heat.

If your stove takes air from your steam room with its blower, it first of all ventilates your steam room, then the underground and through it the air gets back, because has a total volume. There should be a common underground space under all sections of the bath. If the floors are made independent of each other, there will be no ventilation. Floor boards should not be laid tightly, 5-10 mm apart.

Within 15 minutes, the entire air of the bath completely changes, 100% air exchange takes place through the chimney. For additional thermoregulation, you can also open the door of the main room to the dressing room, so that the air goes out there and on to the street.

Optimal scheme for a steam room

There are many schemes with different benefits. Here is one common scheme according to which ventilation in a steam room can be arranged with your own hands. It also allows you to adjust the air flow to maintain one or another mode.

Let's take a closer look. Stove and door on the same side. Air supply behind the stove and through the lower slot of the door. Opposite there are two exhaust ducts (one under the ceiling, the other above the shelf), connected by a pipe or duct.

1. During the heating period of the steam room, both exhaust openings are closed, and the supply ones remain open.
2. During the vaping period, close the top exhaust valve, and the lower one is opened. The circulation of air masses begins: it rushes from the stove to the ceiling, resting against the wall, it goes down. Part of it is pulled out by the bottom flap, and the rest continues to move lower to the floor and back up.
3. After vaping, both exhaust valves are opened to dry the bath.

Application of mechanical and combined ventilation

In pair rooms, ventilation can be arranged in several options. In addition to natural, mechanical and combined ventilation is used in the steam room. It mainly depends on the layout, for example, if the bathhouse is attached to a residential building. When only one wall borders on the street and all the valves are installed on it, then ventilation in the steam room cannot do without mechanical induction.

In a mechanical and combined ventilation system, special devices are used that control air exchange.

The lower the ventilation holes are placed, the more heat will be stored in the steam room. To reach good result it is necessary to additionally equip the ventilation system mechanical devices... For this, deflectors or simple fans are used in air ducts. Air exchange proceeds according to the same scheme, only the removal of unnecessary air from the room is due to the fan. This is a combined system. With a mechanical type of ventilation, a fan is installed in the supply and exhaust ducts.
The type of system is selected individually for each room.

What conditions must be observed

• The temperature regime in the steam room should not be violated. Ventilation must properly distribute air flow without disturbing set temperature: Hot air at the top and cooler closer to the floor.
• To change the speed of air movement, valves with the ability to adjust should be installed on the channels.
• The entry of new air masses into the sweating room should be directly from the street. Based on the characteristics of the building, you can install air ducts.
• To avoid backdraft, make sure there is no difference in area between the exhaust and supply ducts.
• To protect the floors from fire, the underfloor supply duct is installed near the metal sheet of the furnace, blowing cold air around it.
• At the end of the bath, thoroughly dry the floors and all rooms.
• Cover ventilation openings on the outside with rodent-proof grills.

Measurements of the microclimate in the steam room

Each bather has individual requirements for temperature and humidity conditions. They are based on personal feelings. You can achieve the creation of certain parameters using instruments.

Measure the temperature in the steam room with an alcohol thermometer. Do not use a mercury thermometer. You can use an electric thermometer. The thermocouple is placed in the steam room, and the indicator is brought out to the dressing room or the rest room.

Air humidity can be measured with a hygrometer. Based on the individual preferences of the bather, you can use this device to set a certain mode.

What's the bottom line?

Comfortable vaping conditions and ultimately the degree of satisfaction are due to the balanced regime of humidity, heat and the presence of fresh air. To create such conditions, supply and exhaust ventilation... The main thing is to organize it correctly.

Suitable microclimate and correct scheme air ventilation create conditions for better vaping.

Bath procedures are not only one of good ways maintain hygiene, but also the ability to remove accumulated harmful substances and toxins from the body. However, for a visit to be comfortable and beneficial, a good one is necessary to exclude the possibility of the formation of fungi and mold due to high humidity... Ventilation in the bath, equipped by specialists or with your own hands, will allow you to ensure the flow of fresh air into the room and remove exhaust gases and vapors resulting from the operation of the heater and the use of hot water.

Read in the article

Do you really need ventilation in the bath or can you do without it?

The functions of bath ventilation are complicated by the fact that it should facilitate a fairly quick removal from the premises. humid air and qualitatively regulate the temperature in the steam room. It is especially important to have a good exhaust system for baths equipped with gas and solid fuel - to maintain the combustion process in such structures, an impressive volume of air is required. Failure to ventilate will result in an excessive concentration of carbon dioxide, which is harmful to human health and can lead to loss of consciousness.

Inexperienced craftsmen try to carefully insulate the premises, sealing up the smallest gaps in order to increase the heating rate of the steam room and keep it warm for a longer time. However, this is not the right approach, as ventilation holes are required. Competently arranged allows:

• create a healthy microclimate in the bath;
• reduce the concentration of moisture and quickly dry the premises;
• get rid of carbon dioxide;
• quickly warm up the steam room and other bath rooms;
• eliminate stagnant and unpleasant odor;
• get rid of pathogenic fungi and mold;
• keep intact interior decoration premises.

From the above, it becomes clear how important the device is in the bath of the exhaust system. Before making ventilation in the bath, you must first learn about its types and basic installation schemes.

Effective ventilation in the bath - scheme and device

Before you further deal with the exhaust system and start arranging it, you should know that ventilation is natural and forced. There are also differences in ventilation systems and their schemes depending on the location. Well, now about everything in order.

Natural ventilation

This option is optimal for most baths, since it is the cheapest and most effective. The location of the ventilation holes must be determined based on the size of the room, the location of the stove and shelves, as well as the material from which the bath is built. Whatever the ventilation schemes in the baths, there is one general rule - the inlet opening should be located at a height of 20-30 cm from the floor level, and the exhaust outlet at the same distance, but from the ceiling.

The dimensions of the vents should be approximately 300-400 mm 2. In case of too fast air exchange, which will cause a decrease in the temperature in the steam room, the ventilation openings must be covered with special regulating dampers. For improvement appearance it is advisable to mount decorative grilles on vents, which can be easily bought in specialized stores or made by hand.

However, this type of ventilation is not suitable for a steam room. All ventilation openings (inlet and outlet) must be at the same level from the floor. Thus, the incoming air flows are heated from the oven and rise upward, while the cooled air flows downward and fall into the exhaust vents. To preserve heat in the room, the openings can be closed with special shutters.

Forced ventilation

Air movement mechanically carried out by installing special devices on the ventilation openings (). This will allow you to quickly renew the air, which is very important, especially in the washroom. This ventilation option is well suited in cases where U is installed in the bath. forced scheme sauna hoods have a number of advantages over natural:

• there is the possibility of filtering incoming air masses;
• maintaining a given microclimate;
• even distribution of heated air.

For large volumes of fresh air to enter the steam room, it is necessary that the ventilation holes are located diametrically to each other. When installing, do not place the inlet and outlet vents at the same level in order to exclude the closure of air flows, which will cause the concentration of cooled air at the bottom, and on the contrary it will be very hot at the top.

Important! Since high humidity and high temperature are the main enemies of any electrical equipment, the fan case must have reliable moisture protection, and the connection must be made in full compliance with the PUE.

The advantage of forced ventilation is the accelerated air exchange and advanced control parameters. Such an exhaust system is equally effective regardless of the strength and direction of the wind, as well as weather conditions.

Floor ventilation device in saunas

Bath floors are used in extreme conditions. The effect of moisture on the floor is carried out both from the bottom from the side of the soil and from above. The most difficult conditions are created in the steam room, where hot steam is in contact with wood flooring floor, cooling and condensing. The resulting condensation penetrates into and creates a favorable environment for the development of mold and mildew.

Effective circuit Ventilation of the floors helps prevent the damaging effects of mold and remove excess steam. Ventilation of the floor can be carried out naturally or forcedly. However, for efficiency, when constructing a ventilation system, the following conditions must be adhered to:

• prevent the floor from cooling during the adoption of procedures;
• ensure fast and efficient drying, but it is important not to overdo it in order to prevent cracking of the wood;
• the arrangement of the ventilation system must be performed even at the construction stage.

When locating ventilation vents, take into account the climate, wind conditions, landscape, sources of pollution, as well as internal factors - the type and location of the heater, construction doorways, the presence of vents. Most often, ventilation vents are located at 3 different levels:

• under flooring or in;
• under the heating structure or at the level of its foundation;
• in the wall at a distance of 350-450 mm. from floor level (best done behind the heater).

Ventilation under the floors in saunas has a number of advantages. In addition to eliminating condensation and improving the quality of drying flooring, the air flow from below does not form drafts and, therefore, ventilation can be used in the process of taking bath procedures. For greater efficiency, it is important to correctly create drain system to remove drains outside the building.

Creation of air exchange in the basement of the bath

The creation of an exhaust system in the bath is extremely necessary, since it not only allows you to prevent the formation of mold, but also to protect the building from being damaged by rot. The characteristics of the ventilation system are calculated at the design stage. The type and location of ventilation in baths largely depends on the prevailing winds, relief and the presence of reservoirs, which often cause flooding of buildings.

You can ensure normal air circulation by arranging several holes, the number and dimensions of which are calculated in accordance with the dimensions of the bath. The diameter of the vents must be at least 110 mm. Ventilation openings are usually made opposite each other. In the event that a building is located in a lowland, densely surrounded by other buildings, or there are natural barriers to the free movement of air flows, then vents must be arranged on all sides of the foundation, since this is the only way to achieve high-quality ventilation.

Ventilation system in saunas in steam rooms

Traditionally, a stove is installed in the steam room, which forms the basis. The air from the steam room passes through the blower, which ensures good circulation. To obtain the maximum outflow of air masses, the stove should be installed below the level of the finished floor, and to start the ventilation process of the room, it is enough to slightly open the window or the front door. The disadvantage of such a ventilation scheme in the steam rooms of the baths is that when there is no combustion process, the air circulation stops.

In addition to the heater, ventilation in the steam room is provided by additional openings with special dampers to regulate air exchange. After each bathing procedure, you should open it for a while, otherwise the air in the room will be heavy and humid, and there is also a risk of carbon monoxide poisoning.

When the furnace is fired and the room is heated, the ventilation in the steam room must be closed. After the steam room has completely warmed up, the exhaust flaps can be opened. In order to exclude the formation of reverse thrust, it is necessary at the stage to make sure that the exhaust openings are larger in area than the supply openings.

In the event that the stove is not installed in the steam room itself, then a different ventilation scheme is used in steam Russian baths. Nearby at a height of 300 mm. an inlet opening is made from the floor level, and an exhaust opening is arranged at a distance of 300 mm on the wall opposite to it. from the ceiling. Sometimes an inlet is made at the bottom of the wall behind the stove so that the air coming from the street heats up from the stove and the room cools down moderately. On the wall opposite from the heating device, 2 holes are made, which will form a single exhaust duct. The first opening is located at a height of 1,000 mm. from the floor level, and the other under the ceiling. With this ventilation scheme, the steam room warms up faster and, accordingly, saves fuel.

Air exchange device in the washing room

In the washing room, as well as in the steam room, there is high humidity, which contributes to the appearance of mold and mildew. To avoid this, it is necessary to create an effective ventilation system in washing baths... In the washing room a large number of moisture accumulates under the floor, therefore, to drain it, it will be enough to lay an asbestos pipe, one end of which is under the floor covering, and the other is led out to the roof and equipped with a deflector.

Creation of effective controlled ventilation in bath sinks will ensure dryness, moderate temperature, fresh air supply, carbon monoxide removal and fuel economy.

Ventilation scheme in dressing rooms

The proximity of the dressing room to the steam room leads to the fact that condensation settles on the wooden surfaces of the sheathing. To preserve the cladding and prevent decay processes, the room must be well insulated and drafts must be excluded. Most simple circuit ventilation for the dressing room consists in the removal of moist air through the washroom or. It is best to organize a forced-type ventilation system for this room.

How to properly ventilate the bath

Having more or less dealt with the ventilation system in the bath, you also need to take into account other important points. The hood must not:

• cause a violation of the temperature regime in the premises;
• allow cold air to rise to the ceiling;
• remove fresh air from the room.

The principles by which the correct ventilation of the premises is created in the bath depends on the architectural features of the structure of the building. In the event that special slots for water drain are provided in the floors, then fresh air can flow through them and there is no need to make additional exhaust openings.

Often, small windows are made, which, when opened, act as a hood. In addition, if the heater's firebox is located directly in the steam room, then ventilation is even easier - just open the combustion chamber and adjust the air exchange by changing the position of the damper. These are the simplest, but most effective and low-cost options for a ventilation system.

Features of air exchange in frame baths

If in or air circulation is carried out through the rows lower rims, then in frame-type buildings, sheathed big amount thermal insulation material, there is no natural ventilation and for this reason it is necessary to provide for the creation of special openings with dampers.

The most effective system for a bath there is a supply and exhaust ventilation. To organize high-quality air exchange, it is necessary to create two channels. One of them is located near the floor and serves to inflow fresh air into the room (if necessary, you can install a fan), and the second is located at a short distance from the ceiling and is necessary to remove hot and humid air masses and carbon monoxide. Ventilation openings in frame baths should be equipped with special control valves.

When designing a ventilation system, the size and shape of the steam room and the location of the heater must be taken into account.

Chopped sauna ventilation

In the Russian bathhouse, where steam was traditionally prepared by hand, forced air circulation schemes are not suitable. To in wooden baths ventilation natural type contributed to recovery, when creating it, you should adhere to the following schemes:

• to provide the possibility of ventilation (creation of windows, door and ventilation openings);
• the upper borders of doors and windows should be at the same level;
• for small steam rooms, simple ventilation is enough;
• a stove with a chimney is a natural extraction of exhaust air and gases;
• for normal air exchange, you can equip a ventilation inlet with a damper and an exhaust outlet under the ceiling next to the heater.

The device of good ventilation in the bathhouse from the log house is very important point, since it is necessary to exclude the accumulation of excess moisture, which negatively affects the wooden structure and can cause the development of pathogenic fungi and mold.

Ventilation system in a brick building

You should think about arranging ventilation in brick baths even at the construction stage. Since the presence of natural air circulation is not provided for in a brick building, the number and location of openings should be taken into account in advance.

Air exchange system naturally identical to the one that is arranged in the Russian bath - the inlet is located next to the stove, and the exhaust is under the ceiling. However, if the bath is designed for a large number of people, then you should think about creating a forced ventilation system.

The fan must be installed at the inlet of the master exhaust duct on. To speed up the air circulation, several exhaust pipes are installed, but it may be necessary to install supply valves so that the air masses are not discharged due to the difference in the volumes of the supply and extract air. A too powerful fan can lead to the same problem, and a device that does not correspond to the area of ​​the room in terms of power will not be able to perform its functions normally and the air exchange in the steam room will be rather weak.

Recently, new and more efficient solutions have been found to create ventilation systems. Such novelties include the ventilation scheme in the Bastu bathhouse. This system is very popular among Russians due to its ease of installation and high efficiency.

The ventilation principle according to Bast is as follows. The hot stove acts as a heat pump and draws in air from the supply duct. Cold streams, passing through, very quickly heat up and rise to the ceiling. Naturally, they push an equal volume of near-field air through the exhaust duct. In the ventilation system Bastu supply and exhaust openings are located at the bottom.

For the device of such ventilation, two stainless pipes- the lower one is installed diagonally from the heater at a height of 200 mm. from the floor, and the top above the stove. Both exits must be equipped with louvred grilles. However, like all natural ventilation systems, Bastu can only work when the oven is running or when there is a strong wind outside.

The main advantage of the Bastu ventilation installed in Russian baths is the ease of installation, which can be done independently, thereby saving your money.

Competent ventilation device in the bath

Normal ventilation can only be provided if the conditions for the inflow of fresh air and the removal of exhaust air are created in the room. Despite common concepts - ventilation is not entirely true, since it is always supply and exhaust. The principles of ventilation for any premises are practically the same - fresh air enters through the inlet and is discharged through the exhaust.

When calculating ventilation systems, it is necessary to take into account the volume and purpose of the premises, the presence or likelihood of the formation of carbon monoxide or other harmful to health chemical compounds. Normative acts set the frequency of air exchange within an hour, which can fluctuate 1-10 times or more. Next, the parameters and location of future air ducts are determined, taking into account the climatic zones and weather conditions typical for the given area. In the event that natural ventilation is not able to provide the required air exchange rate, then forced-type systems are used.

Where to place the window in the bath?

The windows in the bath are not only a source of light, but also a way of ventilation. There is a misconception that the window in the steam room adversely affects the safety of the steam in the room and the temperature. However, experienced bath attendants are advised to make even two windows in the steam room. One window is located above the shelves, and if the steam turns out to be too hot or someone feels unwell, then just open the window and everything will be in order. The second window is placed under the shelves, which allows you to dry the loungers quite quickly. It is made small and opaque.

Important! According to safety precautions, bath windows must open inward.

It is also worth installing a window in the washing room. It will not only help to ventilate the room, but also to urgently evacuate in case of fire. The dimensions of the window must be such that an average-sized adult can crawl through it. Some bathhouse owners are interested in the question: is it possible to install? If in the washing room, then yes. However, in the steam room, where the temperature reaches a hundred and above, the material from which the windows are made will begin to emit toxic substances and warp. It is best to use non-resinous wood for windows to the steam room. You can easily do the installation of a window in a bathhouse with your own hands, since the technology is no different from its installation in a residential building.

On a note! Sauna windows for greater heat preservation are best done with double glazing and good sealing.

Fan in the air exchange system of the bath

To create a high-quality forced ventilation system, you will need the following parts:

• duct box;
• and lattice;
• damper;
• fan;
• net;

A grate made of wood or heat-resistant plastic and a metal mesh will prevent insects and pets from entering the room. A corrugated hose or galvanized pipe is usually used as an air duct. Experts do not recommend installing in a steam room plastic pipes as they are not designed to withstand high temperatures.

It is advisable to install the fan only on one, for example, on the supply air. The fans used for baths must be made of heat-resistant materials and have good sealing.

A video on how to make a fan with your own hands will more clearly show the process (a bladeless version is presented):

Vent valves

The ventilation valve for the bath is mounted in the supply and exhaust ducts. There are two types of this device - KIV (air infiltration valve) and KPV (forced ventilation valve). Outwardly, they practically do not differ from each other, and the principle of their work is the same. The outer part of the damper is equipped with inclined louvers to exclude the ingress of water from the outside, and the inner part is equipped with a head and membranes for sound and thermal insulation.

When installing valves, several recommendations should be followed:

• for bath ventilation, it is necessary to install dampers made of heat-resistant materials;
• installation must be carried out on the bearing walls of the bath;
• it is not advisable to mount the valves on the walls overlooking the trash can or.

Outlets in the baths

The vents, or as they are also called, vents, can be round, rectangular or square. They are located at the base of the building and on the roof. In the baths, the vents are placed at a distance of 2 meters from each other, and if there are any in the basement, then holes are made in them. These elementary ventilation ducts must also be fitted with rodent-proof grilles.

How to make a hood in a bath

The device of an exhaust hood in a bath with your own hands is a simple matter, but nevertheless it is necessary to approach it with calculation and without haste. First of all, you need to decide on the scheme, the choice of the appropriate materials and calculate the diameter. The supply air volume must be equal to or less than the extracted air. To comply with this condition, it is necessary to know the volume of the room and the rate of air exchange. The air speed in the main line should be no more than 5 m / s, in the steam room - 2 m / s, in the branches - 3 m / s and natural ventilation - 1 m / s. In the table, you can find the pipe diameter most suitable for obtaining the required air volume at the indicated flow rate.

Now, knowing the diameter, it remains to take the corresponding pipe or corrugation and fix one end in the room, and bring the other outside. Self-tapping screws, metallized tape and polyurethane foam... A damper is placed at the entrance, and a grate at the exit. The ventilation ducts should be cleaned at least once a year.

Baths have always been famous for their healing properties. But in order to obtain a healing effect, it is necessary not only to listen to the advice of doctors, but also to organize own bath the correct ventilation system.

Those who have been in the classic village baths made of wood will hardly remember the presence of such steam exhaust holes. In fact, they are not there. After all, a small amount of fresh air entering the bath from cracks in the floor, window or doorway can meet the needs of 2-3 people.

But a bathhouse designed for a large capacity, and even more so a brick one, must necessarily be equipped with a ventilation system to fulfill the following important points:

• the supply of fresh air, which prevents the accumulation of carbon dioxide in the steam room and preserves the health of people in the bath;
• air circulation, which allows you to dry the room after bath procedures. This prevents the appearance of unpleasant odors in the bath, the growth of mold fungi and contributes to an increase in the service life of the building without the need to replace wood elements;
• uniform distribution of heated air in steam room baths.

Moreover, if the hood is arranged correctly, it should not lead to the following unpleasant consequences:

• to a drop in temperature in the steam room during bath procedures;
• violation of the correct stratification of air by temperature - the coolest layer should be at the bottom;
• removal of clean air from the steam room, and not saturated with carbon dioxide.

In a well-ventilated steam room, breathing is easy and relaxing.

How sauna ventilation works

The ventilation system of the bathhouse should be properly foreseen even at the construction stage, because it is at this moment that the hood can be made correctly and independently with the lowest labor and material costs. In addition, the process of making holes in finished structure can lead to a decrease in the strength of the walls.

Air exchange in the bath is provided by means of two openings.

1. The inlet is located at the bottom and provides fresh air to the bath.
2. The air outlet is located at the top on the opposite wall to the inlet. The exhaust air is removed from the steam room. However, if the opening is very close to the ceiling, then hot air is quickly removed from the room, which leads to a decrease in the temperature of the steam room.

This design allows you to adjust the direction of the air flow. At the moment when the bath is heated, all three openings are closed. When people are steaming, the supply and bottom exhaust openings are open. After bath procedures, all ventilation is open, which allows the bath to dry well.

Bath ventilation can be mechanical. In it, the air in the steam room circulates thanks to the pressure equipment. In a more complex and expensive option the air supply process is monitored by special devices that, if necessary, start the ventilation system. The use of a mechanical hood allows you to position holes on any of the walls, as well as correct errors in the organization of natural ventilation.

In any case, to ensure air exchange in the bath, there are several exhaust schemes that differ from each other in the location of the holes.

Methods for ventilation in the bath

We will describe several of the most popular and simple ways of arranging ventilation in a steam room. They can be either with the use of fans or carried out in a completely natural way.

Method 1

This is described above scheme of natural ventilation with one inlet and two outlets. An inlet in such a system is made in the wall immediately behind the stove at a distance of 0.3 m from the floor surface.

To connect the outlet holes with each other, a box is used, which is made of wooden planks, they are laid in it corrugated pipe about one meter long. The holes themselves are fitted with plugs to adjust the air flow as described above. In addition to the plugs, you will also need grates to prevent insects and rodents from entering the bath through the ventilation.

This system is applicable for small baths.

Method 2

This is another simple and most common ventilation scheme for the bath space. In it, the inlet is located behind the stove just above the floor (about 0.3 m). The hood is at the same height, but on the opposite wall, and is equipped with a fan that forcibly draws out the exhaust air.

Method 3

Method 3 is somewhat similar to the previous one. Only the air inlet is arranged at a height of half a meter from the heater, and the outlet is just above the floor (about 0.2 m). The hood is equipped with a fan.

Method 4

Method 4 is used for baths in which the steam room has only one wall facing the street. In this system, the air inlet and outlet openings are located on the same wall opposite the stove. Air enters the lower hole, located at a height of 30 cm from the floor, and exits into the upper one, which is located 30 cm below the ceiling and is equipped with a fan.

Clean air enters the room, collides with the oven, heats up, rises and is directed through the outlet to the outside.

Method 5

Method 5 is suitable for baths in which there are small gaps of half a centimeter between the floorboards. The inlet is located behind the stove. The cooled and exhaust air descends to the floor and exits through the cracks in the underground, where there is an exhaust hole in the wall of the basement, connected to a ventilation pipe that removes air flows above the roof.

Method 6

If the stove in your steam room is heated for the entire period of operation of the bath, then the blower can itself perform the function of ventilation, or rather, an exhaust hood. In this case, only an air intake hole is needed, which is located near the floor opposite the stove. The blower should be slightly lower than the finished floor.

Step-by-step instructions for installing ventilation

When arranging a bath with ventilation, it is important to observe the following conditions:

• if the bathhouse is adjacent to a residential building, then the air flow should go in the direction from the residence to the steam room;
• the exhaust hole is connected to a box or pipe, which must be taken out above the roof of the bath;
• the hood should not be done above the shelves in order to exclude the action of a draft on steamed people.

Generally, the ventilation installation process can be described as follows.

Step 1

In the selected places, the inlet and outlet openings are provided at the construction stage or they are prepared after construction, the cross-section of which should be 10-20 cm.

Step 2

Prepared holes are equipped with boxes made of metal, plastic or wood.

Step 3

Install, if necessary, a fan on the hood.

Note! For baths, it is necessary to use ventilation equipment made of heat-resistant material and with a protection class of at least IP-44.

Step 4

They are mounted on lattice holes and plugs.

Step 5

The outlet is connected to a pipe that is led out above the roof.

Note! In addition to ventilation of the room, it is necessary to ensure air circulation under the floor. For this, at the construction stage, holes are made in the basement on opposite sides, which are closed with gratings to protect against rodents.

In such simple ways, you can arrange a bath ventilation, providing long term steam room service and a comfortable stay in it.

Video - Ventilation scheme in the bath

High quality ventilation system- an obligatory element of the steam room. The absence or improper organization of ventilation in the bath is dangerous to human health. A properly equipped system will protect people from carbon monoxide and improve the comfort of staying in the room. We will talk further about the features and technology of installing the ventilation system in the bath.

Characteristics of proper ventilation for the steam room

Proper ventilation in the bath, it performs several functions at once:

• provides the room with oxygen;
• improves the comfort of being in the steam room;
• removes carbon monoxide;
• allows you to economically use firewood;
• evenly distributes air flows;
• protects the building from the formation of mold or mildew.

The most the best option ventilation in the bath is a supply and exhaust. For these purposes, equip:

• inlet - through them, the flow of fresh air into the steam room is organized, a fan with a ventilation tube is installed, additional air flow is provided by open vents or through the door;
• exhaust hole - removal of heated air from the room, through the firebox, blower or devices that improve traction.

For improvement supply and exhaust system ventilation use different ways... We offer you to familiarize yourself with one of the most efficient ventilation systems:

1. The inlet openings are located at the bottom of the room, next to the firebox.

2. Exhaust holes strictly on the opposite side from the top. It is possible to arrange two openings at once for better air control.

3. The height of the exhaust outlet determines the draft level. If the ventilation opening is low, reinforce the system additionally with a ventilation pipe.

4. With the help of special dampers, air supply from the room is controlled.

5. Air renewal in the steam room is done every 2-3 hours.

In addition, the individual parameters of the ventilation system are determined by the type of room, the version of the bath. For example, in a Russian bath, periodic ventilation will help to renew the air. In addition, the size and place of installation of the furnace are taken into account; in relation to this parameter, two types of ventilation are organized.

How to make ventilation in a steam room with a separate firebox

We offer the option of organizing ventilation in the steam room, the firebox of which is located in the adjacent room. This scheme is popular in ordinary Russian baths. A combustion tunnel is used to bring the firebox into an adjacent room. Among the advantages of such an arrangement of the furnace, we note:

• no garbage in the steam room;
• the door to the room opens only at the entrance;
• the possibility of installing heat-resistant glass for admiring an open flame.

Two methods are used to mount the supply openings indoors:

1. Arrangement of a ventilation duct in the underground space. Removing it in front of the furnace room, installing ventilation grilles on the channel.

2. Floor ventilation supply.

Install the hood on the opposite wall, diagonally in relation to the inlet.

The main quality of the organization of proper ventilation is that the supply openings must coincide in area with the exhaust openings.

Ventilation scheme in a steam room with a firebox inside the room

If the stove is located directly in the steam room, then the ventilation is organized differently. In this case, the air flow through the blower will solve the problem with natural ventilation... This method is appropriate if the fire is constantly in the stove.

If chimney there is no bathhouse, and the stove operates in a short-term mode, a more advanced ventilation system is used. Check out the technology for arranging the ventilation system in the steam room:

1. Build a special brick podium on which the stove will be installed. With its help, a ventilation box is brought to the furnace.

2. Lay the ends, build another box of bricks. As a result, the first structure was installed at the top of the stove channel, and the second - to the steam room door.

3. On a wall adjacent to an ordinary room, build doors in the places where the masonry passes. They heat up the next room, if necessary.

4. A stove is installed on the podium, it is possible to mount it on a corner or on steel pictures. Finish the oven with bricks, install brick screen, with two convection valves.

5. The exhaust ventilation system operates at the expense of the furnace firebox.

Correct installation of the ventilation system is based on its correct adjustment. General rules for controlling the ventilation system:

• at the beginning of the furnace, all openings and supply and exhaust openings are closed;
• wait until the temperature increases, then adjust the ventilation holes with the valves;
• if it is necessary to increase the volume of oxygen in the room, open the inlet;
• upon completion of work, open the doors for better ventilation of the steam room.

Steam room ventilation photo:

To determine the temperature and humidity in the room, use special devices. A thermometer of an alcohol or electric type will help to measure the temperature. Please note that the use of the mercury version is strictly prohibited. Use a hygrometer to check the humidity level.

The principle of operation of the ventilation system is based on the following factors:

• melting the oven, the air gradually heats up and escapes through the convection door;
• the lower door remains open until the oven is fully warmed up;
• close the door from the bottom and work with the top hatch;
• in the process of soaring, only the blower installed on the box opens;
• after using the steam room for its intended purpose, ventilate the room well.

DIY ventilation device in the steam room

The main functions of the ventilation system in the bath:

• air supply during bath procedures;
• high-quality drying of the room.

The ventilation system in the bath should not:

• violate the temperature of the room, in the process of taking bath procedures;
• separate temperature streams, that is, cool air is closer to the floor, and warm air is from above;
• remove unused air from the steam room.

In addition, the lack of ventilation leads to the appearance of unpleasant air in the room, the formation of mold and mildew, which are harmful to human health.

There are three main types of ventilation in the steam room:

• a natural option is the supply of air flows through the pressure difference;
• mechanical version - air supply using special mechanisms, when measuring these characteristics with instruments;
• the combined option is the creation of artificial pressure by fans and hoods.

Indoors, there are two types of air transportation: supply and exhaust. For these purposes, a hole is equipped, located diagonally, in relation to the supply.

It is not recommended to install an exhaust vent in the steam room on the ceiling, this ventilation system increases the heating time of the room. It is rational to install the hood under the ceiling, additionally equipping it with a damper to adjust the draft.

Also, provide a ventilated floor in the bath. This extends the life of the floor covering as it is in constant contact with water. Recommendations for arranging floor ventilation:

1. During the installation of the foundation, provide ventilation of the floors, build vents from the basement part.

2. Install ventilation openings on opposite walls to allow air flow. Install grates on them to avoid rodents.

3. The level of the finished floor should be slightly higher than the blower is located. Thus, it will function as a cooker hood.

4. Install wooden planks with a small gap, at least half a centimeter.

5. After taking bath procedures, ventilate the room well and dry the floors.

Another way of organizing the ventilation system in the bathhouse is “Po Bastu”. In this case, fresh air enters the room from the baking space, and exhaust comes from an opening located near the door. For these purposes, build a wooden exhaust box lined with foil inside.

Build under the floor ventilation duct, next to sheet metal preventing heat from entering it. The size of the structure should not exceed twenty percent. Adjusting the fresh air flow with such a system is quite simple. It is enough to open the ventilation hole and the blower. In addition, it is possible to avoid the accumulation of unpleasant odors in the steam room. This method of organizing ventilation is appropriate if the firebox is located directly in the steam room.

How to organize ventilation in the steam room with your own hands

We offer the five most popular schemes for organizing supply ventilation in a steam room:

1. Scheme No. 1.

Place the inlet under the stove 50 cm from the floor and the outlet on the opposite side thirty centimeters from the ceiling. The forced movement of air masses is provided by a fan. Thus, it is possible to ensure uniform heating of the air. The height of the first opening adjusts the draft force of natural ventilation.

2. Scheme No. 2.

Two ventilation holes are located on the same wall, always opposite the stove. The inlet is set at a distance of thirty centimeters from the floor, and the outlet is thirty centimeters from the ceiling. Install a fan in the outlet, cooled air entering the room collides with the stove, heats up and comes out.

3. Scheme No. 3.

Place the inlet behind the stove, about twenty centimeters from the floor. The inlet is installed at the same height, only close to the ceiling of the opposite wall. A hood is installed in the second hole. The principle of operation of the system is based on the ingress of cooled air into the steam room, passing through the oven and pulling it out with the second hole.

4. Scheme No. 4.

This method is relevant for a steam room with a floor that has holes for water drainage. The inlet is installed behind the furnace, and the outlet is a drain pipe through which air is removed to the outside.

5. Scheme No. 5.

Relevant for a bath with a constantly working stove. The inlet is arranged opposite the stove, and the blower with chimney function as an outlet

If it is necessary to increase the temperature in the steam room, it is enough to close all the plugs. After taking bath procedures, they are removed. It is quite possible to organize these ventilation schemes on your own, without buying expensive devices and special material investments.

How to vaporize a steam room with your own hands

The vapor barrier in the steam room allows you to maintain optimal temperature premises. Special materials in the form of vapor-proof films, insulation and waterproofing will help to create a high-quality vapor barrier. The film protects the insulation from the penetration of water vapor, while not allowing moisture in the hot air to pass through.

A well-equipped vapor barrier and ventilation system increase the service life of the room itself and its exterior decoration... Since hot air rises upward, first of all, qualitatively vaporize the ceiling.

For these purposes, use lacquers, boards, about 6 cm thick. From above, they are covered with aluminum-based foil, cardboard with increased density or wax paper impregnated with linseed oil. After fixing one of these materials, the ceiling is finished with clay and insulated.

In addition, it will help to vaporize the ceiling edged board... On the boards, cardboard impregnated with linseed oil is installed, which is then sheathed with wooden clapboard.

Plates made of expanded polystyrene are a modern replacement for soft clay, they are distinguished by good thermal insulation and operational characteristics.

The following are used as vapor barrier materials for the walls of the steam room:

• roofing material;
• aluminum foil;
• glassine;
• polyethylene based film.

Glassine and roofing felt are rarely used for thermal insulation of a steam room. This is due to the fact that when heated strongly, they emit toxic substances and unpleasant odors. The steam room is vapor-insulated with special foil materials. Combined methods of steam and thermal insulation are distinguished. For example, NPP polypropylene, among its advantages, we note:

• excellent moisture resistance;
• resistance to temperature rise;
• laminated coating prevents the development of mold and mildew;
• combined heat and vapor insulation.

In addition, it is possible to use roll vapor barrier in the form of roll foil or fiberglass plates. For sealing joints between vapor barrier materials, use foil tape.

The boards are installed on the ceiling with a small expansion gap of 20 mm. Thus, the impact of moisture on these areas is reduced. Please note that the vapor barrier in the steam room must be safely hidden behind the main finishing material, and a high-quality ventilation system is its complement.
