SUPPLY VENTILATION DEVICE Russian patent published in 2018 - IPC F24F7/00 

FIELD: ventilation.

SUBSTANCE: invention relates to the field of ventilation and air conditioning, in particular to supply and exhaust ventilation devices. Supply and exhaust ventilation device for placement in the external wall of the building is made in the form of a predominantly cylindrical body, inside which there are separate channels for the formation of supply and exhaust air flows, the channels of the supply and exhaust air flows, in the center of which the axial fan is located, are X-shaped relative to each other. From the suction side to the fan, the air flows divided into two parts are divided into two parts: a stream of clean air from the street to the fan and a dirty airflow to the fan removed from the room. On the side of the injection, symmetrically with the opposite side, the air flows separated from each other into two parts – a stream of clean air from the street into the room and a polluted airflow from the room to the street. Fan axis is located perpendicular to the axis of the air flow, whose blades rotate, alternately touching the supply and exhaust flow, transmit heat energy from one flow to the other. Fan blades are made of a heat-conducting material, preferably aluminum, or copper, or heat-conducting plastic, or plastic with surface metallization.

EFFECT: technical result of the claimed technical solution is to increase the efficiency, increase the heat transfer coefficient and aerodynamic characteristics, and reduce energy consumption.
