A re-circulation installation of aerodynamic air heating includes body, main centrifugal rotor, movable guides. Additionally a heat-insulated body is included to installation, in this one an additional centrifugal rotor with larger diameter is installed, this is installed concentrically with respect to the main one. The main and additional centrifugal rotors are installed with possibility of connection to separate independent outer electric motors that are arranged with possibility of rotation to different sides. On the front section of the heat-insulated body a suction opening is placed, and the inner supercharge cavity is connected with openings at its side surface to the inner re-circulation chamber and the long and cross air ducts and the outer re-circulation chamber inner cavity of which has openings that connect it to long and cross air ducts. |
