Beschreibung
Zusammenfassung:	manufacture of ventilation devices; applicable in regulation of ejector ventilation plants in ventilation of sections of ventilation system. SUBSTANCE: method is characterized by the fact that air flow are regulated by variation of distance between sections of fan outlet and inlet of mixing chamber, and by variation of angle of setting of blades of guide vanes. EFFECT: increased range of aerodynamic parameters of ventilation plants with regulated fans and regulation of ejector ventilation plants with nonregulated fans. 1 dwg
