Natural ventilation in a private house

Ventilation in a residential building. Previously, ventilation was provided due to the flow of clean air through the cracks in the windows of wood. But in our time, the buildings are collected in plastic windows, which is characterized by great impermeability — here natural ventilation is not possible. And systematic ventilation of the premises does not always make it possible to resolve the issue of air cleaning. It is spectacular in winter, and in the summer, dust and various allergens fall from the street along with the air. All these problems can be solved using the design of air ventilation and air conditioning.
