The article considers the influence of local exhaust ventilation parameters on the quality of the room’s air environment. On the basis of experimental studies, dependencies were established that determine the effect of mass transfer processes occurring in the local exhaust ventilation shelter on air quality in a room working area. The influence of a flat plate installed in the lower part of technological opening of a shelter that prevents incoming air movement from a room to a source surface of convective jet is determined. This measure made it possible to reduce the air velocity above surface source and the amount of harmful emissions by 2.5 times, as well as to reduce their flow into a room through an opening a shelter. These measures allow to reduce energy costs for room ventilation and improve air quality in the serviced room.
