Title Air diffusion in sorting rooms at domestic waste treatment centres - Study of the ventilation characteristics of four air input systems

Abstract The INRS recommends that an overhead air supply island be placed above each workstation in domestic waste sorting premises. In this study, the aerological performance of various types of air supply islands were evaluated based on measured air velocities at the exit of the unit and at the breathing level of potential operators. It was found that a system comprised of a simple casing with a single perforated grill (perforation ratio above 45%) is insufficient to ensure a properly- directed flow. Acceptable performance can be obtained with two grills (perforation ratio below 32%) or with a casing fitted with a filter.
