Effective ventilation in the country

The ventilation system determines the comfort of using a country house. Insufficient supply of fresh air leads to unpleasant consequences: odors stagnate in the premises, natural humidity is disturbed, mold and pathogens develop. Efficient ventilation in the country house creates an optimal temperature and humidity regime for a person and a building, regardless of weather conditions.

Ventilation in the country: types of systems and their capabilities

Ventilation in the country house is divided into:

1. Zonal and centralized.
   The centralized system covers all the premises of the country house: from the basement to the attic. Air masses alternately pass through the rooms and are removed through the ventilation openings. Zonal works in a specific room. For example, ventilation of the toilet in the country house or in the kitchen is arranged separately – in areas that need additional ventilation.
2. natural and forced.
   According to the method of organization, ventilation in the country is divided into natural and forced. Natural ventilation is created by the difference in temperature and pressure inside and outside the room. Fresh air enters the ventilation shaft through natural gaps, cracks, joints and is removed through the ventilation openings. The effectiveness of natural ventilation is directly dependent on weather conditions. The tightness of modern buildings makes it difficult for air to flow in sufficient volume. Therefore, forced ventilation systems are more often used. In them, air is pumped in by fans and removed through the provided mines. Forced ventilation allows you to control the volume of incoming air and maintains air exchange in any room.

Equipment for ventilation of the cellar in the country is able to solve additional tasks: to drain the room, heat the air masses, and prevent rooms from freezing during the cold season.

Sanitary requirements for ventilation of a country house

SanPin 2.1.2.2645-10 establishes strict rules regarding the arrangement of ventilation of residential premises, including cottages ^

• it is not allowed to combine the ventilation ducts of the kitchen and bathroom with the ventilation of living rooms;
• the speed of air movement in residential premises should not exceed 0.2-0.3 m / s (for the cold and warm seasons, respectively);
• at least 25 m3 of air should flow into a separate bathroom within an hour.

Forced ventilation system and zonal ventilation in the shower and in the kitchen of the cottage creates the conditions for a comfortable and healthy life, in accordance with hygienic requirements.

Equipment for forced ventilation in the country

The choice of ventilation equipment is the first task when creating a forced ventilation system. Alternative energy fans have proven themselves well:air solar collectors.

Solar energy is actively used to meet domestic needs. The general principle of operation of solar-powered equipment is as follows: the device automatically turns on when sunlight hits it. The air is heated and blown into the room with the help of a fan, and then removed either through natural gaps or through a ventilation shaft.The choice in favor of alternative fuel sources will reduce the cost of electricity consumption– the equipment is autonomous, does not require connection to the mains. In order for the ventilation in the cottage kitchen to work at full capacity, the device is installed on the sunny side of the house or on the roof – where there is no shading.

Since solar energy is ubiquitous, it is used to create ventilation in the country house in remote settlements, at non-electrified facilities, in buildings under construction, makeshift houses, and unheated houses.
