SYSTEM FOR CONTROLLING AIR FLOW IN VENTILATION SYSTEM Russian patent published in 2024 - IPC G05B19/00 F24F11/00 

FIELD: ventilation.

SUBSTANCE: proposed invention relates to control of air flow rate in ventilation systems with two or more air supply (discharge) zones. System for controlling the air flow rate in the ventilation system includes a ventilation unit with air ducts connected to it, on which valves are located, made with flaps, on the shafts of which there are drives, wherein the system is additionally equipped with a control system, comprising a controller with a pressure sensor, an air speed sensor, valve drives and a frequency drive connected thereto, pressure sensor and air speed sensor are installed on the common section of the air duct and are configured to measure the total pressure and total flow rate in the system, and transmit data to the controller, frequency drive is made with possibility to change ventilation unit performance by changing ventilation unit fan revolutions, wherein the controller is configured to set the values of revolutions of the ventilation unit and control the position of the flaps of the valves, record and convert the measured values of pressure and air velocity into the data set, as well as with the possibility of executing the trained neural network.

EFFECT: possibility of calculating the position of flaps of valves to maintain the required air flow rate taking into account mutual influence of valves on each other.
