AIR MANIFOLD Russian patent published in 2009 - IPC F24F13/06 

FIELD: heating.

SUBSTANCE: invention relates to air ventilation engineering and allows for automatic reducing of temperature drops between plenum flows and room air and controlling plenum air flow rate by means of automatic control instrumentation. The threaded pins are fixed in the center of each choke provided with the shape of cylindrical inlet nozzle. The nuts are screwed in the threaded pins and rods are fixed to the nuts end surfaces. The opposite ends of the rods are fastened together by means of round plates. The output shafts of actuators are fastened to the centres of plates in coaxial alignment with pins. Besides rotation of actuator shafts together with the nuts ensure translational movement of pins and fastened to the pins chokes in either of directions depending on shaft rotation. The actuators are placed on brackets fixed to inlet nozzle surface and are electrically connected to air temperature regulator, which is connected with temperature sensor in the room. The axis of choke located before convergent insertion inlet is in axial alignment with output shaft of the actuator, which is also placed on the bracket fixed to inlet nozzle. The inlet nozzle has electrical connection with air flow rate regulator which is coupled with flow rate sensor being positions at air outlet from air manifold.

EFFECT: fast fading of plenum jets and their even distribution throughout room volume, prevention of actuators (chokes) position change due to air manifold vibration.
