The effective operation of ventilation systems depends on how its components are correctly calculated and selected accordingly. However, it happens that the actual and calculated parameters of operation often differ, especially in cases where linear louver diffusers are used. Such a difference in characteristics arises from the fact that, usually, formulas and nomograms for the selection of linear diffusers are built for conditions when the jets are free, in actual operating conditions the jets are not free.
This article considers the influence of the enclosing structures of the room on the jet formed by a linear louver diffuser. Such devices have a small width with a significant length of the air outlet slots, which affects the characteristics of the jet. Such features of the operation of these diffusers must be taken into account at the stages of design, operation, and adjustment to ensure optimal microclimate parameters.
