Ventilation in a room without windows is an urgent problem, since if you do not organize automatic air purification, it will be uncomfortable to be in the room. It will become stuffy, it will be damp, a fungus will begin to form, it is elementary harmful to breathe such air. In order to avoid many problems, it is necessary to think over an artificial ventilation system.
How to check if a room is ventilated without a window?
Most often, in houses, especially multi-apartment buildings, the developer provides a natural ventilation system. It is structured as follows: the exchange of air takes place along vertically located channels that run from the roof of the house to the basement itself. The unventilated premises of the apartments are connected to the ventilation system via special outlets. For many reasons, ventilation in the room may not work.
In order to check the performance of the ventilation system, you need to set fire to a folded sheet of newspaper and bring it to the grate. It should be kept at a distance of 2 cm, if the paper is pressed against the grate, then the ventilation works correctly, and nothing interferes with air circulation. If smoke goes into the room or the sheet is not compressed by the air flow, then there is no hood.
Tip: When checking how the system works, do not use open fire. Newsprint should be smoking but not burning. Open fire can be dangerous, as flammable and various flammable substances can form in a clogged exhaust pipe.
The role of air circulation systems
Ventilation in a room without windows plays an important role. Even if the room is used infrequently, carbon dioxide builds up in it. If more than one person is constantly in the room, heat is generated in the amount of 60 W per hour, it creates excess moisture, which, in the absence of natural or artificial ventilation, will settle on the walls. As a result, it will be very stuffy inside, a fungus will form on the walls, the spores of which are dangerous to breathe.
Clean ventilation ducts may not always provide the right amount of fresh airflow, even if the room has a window. The fact is that deaf plastic products reliably isolate the room. There are positive aspects to this, but there are also disadvantages, for example, the room is not ventilated by itself. With the help of special equipment, the problem can be solved: the system will forcibly ventilate the room.
Arrangement of forced ventilation
Knowing how to make ventilation in a room without windows or with blind structures, you can do the work yourself. This requires two fans with approximately the same power. In addition, you will need to purchase a heater and a filter; one device will be enough for the system to work.
In order for the air to be taken from where, ducts for ventilation are punched in the walls. Pipes will be inserted there: to arrange the holes for them, you will need to use a puncher.
Ventilation duct diameter
It is not enough to punch a through hole of any size: you need to act on the basis that for 1 m 2 the hole should be 1.5 cm in diameter; if the room is 20 meters, you will need to punch a 20 cm hole.
In order for the ventilation to work well and at the same time not interfere, the hole must be placed slightly above the floor level. The air duct should extend to the street by 40 mm. It must be directed upward: this will ensure optimal air intake, return of polluted air from the room. To prevent debris from entering the pipe, it is protected with a special canopy and mesh.
Ventilation in a room without a window is performed in the form of an air duct with perforations on the walls; it can be positioned either vertically or horizontally. This device is needed so that the air is evenly distributed in the room. To ensure the exhaust of stale air, an exhaust hood is installed. It is located in the upper part of the wall, about 50 cm from the ceiling, if the house is private, the pipe must be raised above the roof to a height of at least 30 cm. In an apartment, you can run it along the wall to the same height. In both cases, the pipe must face up.
Ventilation in a room without windows will be more effective if the exhaust pipe is also equipped with a jig canopy and a mesh. This will prevent it from clogging up with various debris.
In order for air to be efficiently drawn into the duct, a sufficient fan must be used. Outdoor air enters the room after passing through a filter.

Selection of ready-made solutions
If the bedroom does not have a window, ventilation can be provided using factory-supplied fresh air devices: these are called airgivers. Most often, such a device is installed outside the window. The system will not spoil the appearance of the facade, since it has a small size, is placed in a special box, the color of which can be chosen, the outside is closed with a practical and attractive outwardly grating through which air is drawn in.
The average cost of an imported airgiver is 25 thousand rubles. The device is suitable for use in rooms with an area not exceeding 35 meters. Some airgivers have a heating function: this is convenient in winter, since warm air will flow into the room, there will be no feeling of draft, the room will not cool down. As a result, the operation of the system provides a decrease in heat loss and savings on heating.
Depending on the model and manufacturer, the airgiver can operate in different modes: for example, you can set the desired fan speed. More expensive devices show how dirty the filter is and when it is time to change it, which greatly facilitates maintenance, avoids productivity loss and breakdowns. Details about ventilation systems.
Conclusion: if you have a room without a window, ventilation is necessary in it. It will make the room comfortable and safe for health. What type of ventilation to choose depends on the preferences and financial capabilities of the owner of the premises.
