GAS PURIFICATION SET WITH THE GAS FLOW RATE MEASUREMENT FUNCTION AND METHOD FOR MEASURING THE GAS FLOW RATE Russian patent published in 2022 - IPC B01D46/00 B01D46/46 B01D53/02 G05B19/42 F24F3/16 F24F11/39 

FIELD: treatment of gas.

SUBSTANCE: group of inventions relates to gas purification sets with the gas flow rate measurement function, used to ensure automatic adjustment of air exchange in the purified indoor area. Claimed system can be used in indoor air conditioning systems of any type, namely, in filtration units of such air conditioning systems. Gas purification set with a gas flow rate measurement function comprises an inlet, an outlet, an air duct formed by the body walls of the gas purification set, a fan, at least one filter including a filter membrane, and at least one pressure sensor. The filter herein is located in the air duct between the inlet and outlet. At least one hole and at least four grooves are made in the membrane on the side of the filter. One end of each of the grooves herein extends onto the edge of the inlet of the filter, and the other end is connected with each other groove along a circumference concentric to the inlet in the membrane, so that the membrane of the filter is configured to be used as a narrowing apparatus. Also claimed is a method for measuring the gas flow rate using the gas purification set.

EFFECT: automatic adjustment of air exchange in the purified indoor area, effective air purification, and highly precise gas flow rate measurement without additional hard-to-make elements.
