In recent years, the popularity of country houses and cottages has increased sharply as places for permanent residence during the year. In this regard, the ventilation problem has become more urgent. Ventilation of cottages is a complex communication system that should interact with air conditioning and heating systems and create, regardless of the season, more comfortable conditions of the microclimate of the premises.
In summer, the parameters range from 22 to 24 degrees, in winter from 20 to 22 with the mobility of air flows from 0.2 to 0.15 m/s. The concentration of substances and impurities harmful to humans (kitchen evaporation, tobacco smoke, gaseous discharge from synthetic materials), which the ventilation system should be cleaned and removed by the perimeter of the building, should also be taken into account. In cottage-type buildings, mechanical supply and exhaust ventilation was widespread, since it allows you to provide fresh air in the building with unlimited area and number of storeys, as well as equipped with metal-plastic windows, which make it difficult for the natural ventilation process. This is an automated ventilation system, in the principle of operation of which includes ensuring the optimal ratio of the flow of fresh air and the removal of exhaust gases.
