FIELD: heating.
SUBSTANCE: invention relates to methods of regulation of air flows in the ventilation system. The purpose of the invention is self-regulation of air flow during operation of the mechanical ventilation network due to creation of the torsional aerodynamic forces and torques in the pipeline and its branches. The effect of self-regulation of the air flow is automatic maintaining of the constant flow rate in the branch in change in its amount in the pipeline of the ventilation system by adjusting the area of the air free passage as a result of the emergence of the total aerodynamic control torque. When using the gas-dynamic method of self-regulation of the airflow in a ventilation system by cutting off a certain amount of air in the automatic regulator the outflow of heat is decreased, contained in the cut-off air, which can be used for recycling or other purposes.
EFFECT: cost savings for heating the air; in addition, due to self-regulation the constant air flow in the branch is provided.
