INSTALLATION FOR ASSESSING DISTRIBUTION OF AEROSOL CONCENTRATIONS OF HARMFUL SUBSTANCES IN AIR OF VENTILATED CHAMBER WITH INTERNAL PARTITIONS Russian patent published in 2021 - IPC G01N35/08 G01N1/22 G01D21/02 

FIELD: ventilation systems.

SUBSTANCE: invention relates to assessing the distribution of aerosol concentrations of harmful substances in the air of a ventilated chamber. Installation for assessing the distribution of aerosol concentrations of harmful substances in the air of a ventilated chamber with internal partitions consists of a stationary frame object with the internal volume of 760 m³ made in the form of a parallelepiped with a gable roof, ten windows on the sidewalls and two doors on the end walls. The installation contains internal partitions dividing it into separate rooms with the internal volume from 20 m³ to 150 m³ and a hall. The installation also includes devices for air sampling, which are model 822 aspirators with sampling tubes connected to the device with vacuum hose, four filter-ventilating devices fixed with bolts and nuts on the chamber walls, which allow performing the specified ventilation modes.

EFFECT: invention provides a possibility of air sampling using technical means of control located at different heights of the object with functioning filter-ventilating devices providing the specified air ventilation mode inside of multi-room stationary objects.
