The ventilation system in a residential building is an organized air exchange, as a result of which from the utility and residential premises, removes harmful components, various smells, unnecessary moisture, and so on.
The supply ventilation system in the house.
Until recently, the supply ventilation system in residential buildings of individual use was arranged due to the receipt of cool air through loosely closed holes in the windows and walls – this was even written in the corresponding norms.

The supply ventilation system in a residential building is carried out mechanically with a ventilation installation or in a natural way, through special wall and window valves. It should be noted that the periodic ventilation of residential premises, for example, through the window does not solve this problem quite fully, since the exchange of air in the house is constantly necessary.
Exhaust ventilation system in the house.
The natural ventilation system works using ventilation traction, which occurs due to different pressures between the street and the room. Different pressure are determined by different temperatures between the room and the street and various heights of the air intake grilles and the top of the extract of the extract.
In such a field, the natural ventilation system practically does not work in the summer and works much poorly on the last floors of a residential building.
Designing the ventilation system of a residential building is performed in a certain sequence:
1) The calculation of air metabolism is determined by the individual premises of the house
2) you need to choose a constructive circuit of the ventilation system
3) choose and place ventilation equipment
4) tracing of air bends
