DEVICE FOR INDICATION OF AIR FLOW DISTRIBUTION BY AIR FLOW REGULATOR OF GAS DYNAMIC TYPE Russian patent published in 2021 - IPC F24F11/00 

FIELD: ventilation.

SUBSTANCE: invention relates to the field of forced-type mechanical ventilation, namely to devices for indicating the amount of air flow. Self-regulating mechanical ventilation network with indicator automatic air flow control device, which contains a device for outside air intake, a fan, air distributors, air flow control devices, tees, main branch and branches. Instead of the existing devices and methods of control over the regulation of air flow in the main and in the branches of the air duct network, as well as control in the premises of the complex storage arsenal, an indication air flow controller of the gas-dynamic type is proposed, the principle of operation of which is based on the features of the distribution of air flows in the tee, which provides automatic control air consumption and the formation of a control signal, which is displayed on the dashboard.

EFFECT: objective of the invention is to display the air flow rate on the dashboard, when the mechanical ventilation network is operating, through the use of a device that allows generating a signal from the gas-dynamic type air flow controller.
