Efficiency of general ventilation systems in closed parking areas
Annotation
The article presents a comparative analysis of the efficiency of traditional cross-channel and longitudinal jet systems of general ventilation. The features of the general ventilation of closed parking areas are considered. Analysis of numerical modeling (CFD modeling) results showed the advantage of the longitudinal jet ventilation system, which provides uniform ventilation of the parking area and the absence of dead zones. It is shown that separate removal of air from the upper and lower zones of the parking area, in accordance with the requirements, does not solve the problem of uneven CO concentration in the volume of the parking space, either in the case of longitudinal or transverse direction of the ventilation air flow. The advantage of jet ventilation, in addition, is the energy efficiency and the quality of the air environment, the ventilated room, which can be reflected in the rating according to the norms of green building.
