The project of ventilation of the frame house is the key to a healthy microclimate of your home and the confidence that the house will not rot in a couple of seasons due to high humidity.
For what reason does high humidity occur in the house? People breathe, use the bathroom, cook food. All these processes, as you know, are accompanied by the evaporation of moisture. In addition, at a plus temperature in the house, humidity is always higher than outside. Moisture always seeks to go out through the walls of the house. In order to prevent this process, there is a vapor barrier film in the frame of the frame wall that protects the insulation and the frame of the building from destruction. However, the problem of increased humidity in the room itself arises. To minimize this problem, you should think in advance how the flow of fresh air will be carried out into the room, and how humid will go out. For this, the ventilation system is installed. The absence of this system will be manifested by the appearance of condensate and mold on the walls of the frame house. Increased humidity also provokes an increase in the frequency of diseases of the upper respiratory tract in residents of this house.
The flow of fresh air is carried out through the window valves, and the outflow through the fans reacting to the change in humidity in the room.
Currently, the production of duct fans to order does not represent any difficulties, and therefore, at the design stage, the places of laying of the ventilation system channels should be provided, and ventilation equipment. Otherwise, there will be a need to lower the ceilings or cross the lags of the ceilings. The project also needs to provide for the presence of ventilation mines, in which the ventilation pipes will be located, as well as a chimney from a stove or fireplace.
For example, in North America, the ventilation of the frame house is combined with the air heating system and the air conditioning system. If you also want to use this option, then you should discuss this issue with the process engineer-designer of heating and ventilation systems.
