It is difficult to overestimate the general health effect of systematically obtaining bath procedures. After all, this is connected not only with health promotion, but also with pleasant leisure activities in an attractive company with close friends.

And it is unpleasant when relaxed pastime is interrupted by fog in the room, which can occur if there is no exhaust. Therefore, the ventilation in the bath is so important, and the timely circulation of air depends on the circuit and device of which.

The general principle of ventilation in the bath

The type of exhaust is selected in each case separately and is determined by the dimensions of the building, the material from which walls and ceiling, as well as from its location.

Why does ventilation in the bath and sauna

In addition to the fact that the hood in the sauna room is necessary in order not to get angry, it is also necessary in other cases:

  1. Replenishment e level oxygen . When burning a fuel, oxygen is consumed, and its lack directly affects people's well-being.

  2. Circulation I air . Due to ventilation, there is an even distribution of hot air throughout the bath (sauna), and hence more comfortable conditions.

  3. The output of the "spent" polluted air . Human health is directly dependent on this. This is especially important when there are many visitors in the steam room.

  4. Drying and rooms . It is important for protection from decay of wooden buildings (shelves, benches, floors).

  5. Displays unpleasant odors , if any.

At the same time, the hood is designed to maintain thermal equilibrium, to keep hot steam indoors, otherwise the meaning of visiting the sauna is lost. At the same time, it is necessary to carefully approach the design, since due to incorrect ventilation, drafts can form in the steam room, and these are colds and other unpleasant moments.

The scheme of proper arrangement of ventilation in the steam room

It must be borne in mind that there is no definite recommendation on which ventilation system to use, so how much depends on the design of the bath and its layout, which has more than one dozen.

Types of ventilation, the method of calculating them

The principle of air exchange in any room consists in the movement of air flow from the area of ​​high pressure to the area of ​​low pressure. As the air expands when heated, its pressure increases and warm streams tend to go outside.

Polluted air is drawn out as a result, and in order to restore the balance of air masses, fresh air is taken.

There are several types of ventilation.

Natural extractor

Such air exchange is the most common option for many baths, it is the lowest in price and quite effective. At the time of selecting the exit gate, you need to pay attention to the places where they will be located on the walls outside. It is advisable to select them so that they do not stand out from the background of the wall surface.

It is important to remember! The cross-section of the holes for the hood is 350-400 cm 2 , and the output channel is 1.2 times larger than the inlet channel.

In case the air intake is enhanced, the inlet duct can also be covered with an adjustable gate. Holes in the walls are taken with decorative gratings.

On our website you can find contacts of construction companies that offer design and construction services baths. Directly to communicate with representatives, you can visit the exhibition of houses "Low-rise Country".

Separate several types of natural ventilation:

  • Channels are located at different heights, usually fresh air - 25 cm from the floor, and the output is 25-30 cm from the ceiling.

  • Exhausting fumes and carbon monoxide through a chimney.

  • Circulation of air through the grate or in advance provided slots in the floor.

As well as in addition to the vents, a gap of 4-8 cm is left in the doorway, through which fresh air flows.

Mechanical ventilation

Forced exhaust is characterized by the fact that it is connected with the device of electrical appliances. Therefore, special attention should be paid to the protection of equipment from moisture.

The connection must be made by experts, according to all standards of OLC (rules for electrical installations). This is due to the high temperature and humidity of the air - the inevitable "enemies" of any equipment.

When choosing this type of ventilation, you need to take into account its advantages:

  1. Heat transfer in the steam room is noticeably accelerated, which increases comfort.

  2. The parameters of the adjustments increase (it can be made even from the console with the appropriate equipment).

  3. Independence from climatic conditions. This is especially true with side wind. Natural ventilation in this case becomes an ineffective hood.

There are two types of forced extraction:

Controlled by electronics . This system automatically monitors the temperature and humidity of the air, and if necessary, opens the inlet channel to adjust the flow and purification of air masses.

Combined method of air inflow and air extraction . The main ventilation in such cases is natural, and if it does not cope with the air exchange, the forced one is additionally started.

Fundamentals of calculation of exhaust

When performing calculations of air exchange, many different factors should be taken into account: the volume of the steam room or the washing compartment, the results of air, and the likelihood of carbon monoxide formation.

Attention! Standard specifications regulate the rate of air exchange for one hour. For baths it is 2-4 times per hour.

After performing the calculations, the experts determine the parameters and the location of the holes for the desired circulation, taking into account the region and weather conditions.

If the necessary air circulation cannot be provided by natural exhaust, artificial ventilation is calculated, taking into account the specific features of the planning of a particular bath.

stages of installation, types, scheme and device

Ventilation can be calculated for different air exchange schemes.

All ventilation is calculated to prevent sudden thermal drops in the steam room. To avoid such a phenomenon, in which the body is under the action of heat, and cold air is blowing along the legs.

A difference in degrees of air flow will occur, and this, of course, but there should be no inconvenience. This is another ventilation task - to equalize the air temperature by mixing it.

General rules for installation of an exhaust hood in a bath

Standards for ventilation of premises are regulated in SNiP 41-01-2003. These documents talk about the establishment of air exchange rate in different rooms, depending on their purpose and the characteristics of the application.

For a bath, these tasks are hampered by the fact that the ventilation system must quickly displace humid air, and at the same time maintain the optimum temperature in the double compartment.

In addition, it is necessary to take into account that bath procedures are accepted by people of different ages. In addition to the steam room itself, there may be situations when the stove still gives off heat, and children need to be washed. To adjust the temperature here without ventilation is not enough, because without it you will not be able to quickly ventilate the room and reduce the temperature to the desired values.

Obviously about the ventilation in the Russian bath, look in the video:

The dependence of the ventilation system of the bath on the type of construction

In the log and assembled from the bar bath justifies natural exhaust, but provided that the vents are properly located and they correspond to their specified dimensions.

If the bath is a frame, then it is assumed that it is airtight. Therefore, to ensure the flow and uniform circulation of air, a fan should be installed in such a room.

Bath and sauna, built of brick, cinder block or foam blocks, provided only by artificial ventilation.

Installation of ventilation systems

In the baths, both the intake and exhaust ventilation systems are calculated. Their work is balanced by the influx of not only fresh air from the street, but also taking into account the flow or outflow of air from adjacent rooms.

In the steam room ventilation for the bath is also allowed exhaust or intake. In this case, the air circulation occurs from the waiting room through a special opening or flows into the adjacent room.

Natural air exchange in a wooden bath is the cheapest option. This is due to the fact that in the walls, already during construction, you can simply leave the holes of the required diameter.

They contain metal or plastic air ducts, and on the outside are installed air circulation grilles . At the same time, such a hood must be equipped with an adjustable damper.

It is covered to a greater or lesser degree, depending on the season of the year, or when the room is warming up.The installation site of the ventilation duct should provide a stable air flow, on the one hand, and free access to it, on the other.

In the baths, the forced ventilation equipment is installed from the outside in through holes, and the control is located in a room with low humidity: a waiting room or in a rest room.

During operation, all the structural elements of the bath are influenced by high humidity - this is especially true for wood products. In order to neutralize the effects of humidity, there is an outlet in the basement through which fresh air penetrates to the wooden floor, drying the room.

Sometimes such an element is an integral part of the air flow in the general ventilation system.

About the varieties, operation and installation of ventilation, see the video:

Important! When choosing a ventilation scheme for a steam room in the bath, you should look to the intake channel It was placed closer to the furnace, and the exhaust port was located in the far corner. This is justified by the fact that fresh air, when released into the oven zone, heats up quickly and does not cool the floor, which is important in the bathing procedure.

In a small room of the Russian bath sauna, proper ventilation is a guarantee of not only your health, but also of safety in general, without any difference what the bath is heated with: wood, coal or electricity. .

The purification of the air environment from harmful impurities directly depends on it, a comfortable heat exchange and only then the bathing procedure will be favorable.
