The installation of plastic windows and doors negates the possibility of the functioning of the natural ventilation of a private house. Ventilation equipment in a home starts with air exchange calculations. Based on these data, ducts of suitable diameter are purchased, the type of ventilation is determined. The scheme of natural ventilation of the house contains the places where air is removed outside the house, the places where fresh air is drawn into the house, the scheme of exhaust pipelines.
Natural ventilation of a private house
Natural ventilation of a private house is arranged regardless of the number of storeys of the cottage. Unfortunately, this ventilation system has its drawbacks: flies and mosquitoes, dust, tree fluff can fly into the room through open vents and air ducts. Therefore, they are covered with nets. An inflow of fresh air is provided and special ventilation valves mounted directly on a plastic window from the inside or on a wall.
Air movement around the house is provided by:
- Open vents (valves);
- Doorways;
- Ventilation ducts.
The natural ventilation scheme of the house divides the entire area into three zones: air inflow, overflow and exhaust. In the inflow zone, air enters the house, passes through the entire area, which is the overflow zone, and goes out. To make the movement more intensive, a fan with dampers is installed on the inlet channel, which control the air flow. The valve is mounted near the windows and behind the radiators so that the air entering the house is warmed up and only after that it enters the room.
Natural ventilation at home is the cheapest and easiest to install type.
Exhaust duct
The exhaust duct is designed at the stage of wall construction, as it is equipped with brickwork. It should go out at least 1 meter above the roof of the building. Moreover, the more floors in the cottage, the better the traction will be.
The optimum height is 5 - 6 m. The diameter of the channel should be 10x10 cm. Its cross-section can be square or round. But the circular section hinders the movement of the air stream less.
Most owners of private houses equip a mine for natural ventilation of the house in the wall. The laying should be done carefully, as even mortar scraps can interfere with the passage of air. A small door should be equipped to clean the ventilation.
To prevent snow or rain from falling into the ventilation pipe, an "umbrella" is installed on top. And you can monitor the intensity of natural ventilation in a private house using an insulated valve.
