Optimization of Work of Ventilation System in the Building with "Warm Attic"

The article is devoted to the optimization of the ventilation system of a residential house with a warm attic. A new technical solution was proposed for the installation of an industrial fan in the space of a warm attic. The operation of such a system is provided by the phenomenon of ejection. The article presents the proposed method for calculating the ejection stream of an industrial fan. The advantages of this ventilation system were listed on the basis of the analysis. There is a table comparing the centrifugal exhaust fan with individual exhaust fans in the conclusion of the article. (paper)
