TERMINAL DEVICE FOR AIR SUPPLY Russian patent published in 2014 - IPC F24F1/00 

FIELD: heating.

SUBSTANCE: invention relates to a terminal device for air supply. The fresh airflow (L1) is supplied from the air supply chamber through the nozzles into the annular mixing chamber. The circulating air flow (L2) is supplied from the room space into the cylindrical suction chamber in the annular heat exchanger. From the suction chamber the circulating air flow (L2) passes through the heat exchanger into the mixing chamber. The nozzles are located in the upper part of the mixing chamber at a distance from each other along the periphery of at least one circle, as a result the middle point (centre) of the circle is located on the vertical central axis of the terminal device for supplying air. The horizontal component of the directing vector of the flow (L1) of fresh air discharged from each nozzle forms an angle which is in the range of 45-135 degrees with a radius of the said at least one circle, and the directing vector is directed downwards relative to the horizontal plane at an angle which is in the range of 15-75 degrees, as a result in the mixing chamber a vortex air flow directed downwards is formed.

EFFECT: improvement of design.
