Abstract

Abstract

For different industrial facilities, indoor air quality is a crucial factor in assessing the work environment as it relates to the health and comfort of the workers. Industrial ventilation is mandatory, as contamination emission rates are often much higher than in non-industrial facilities. Rather than industrial air quality and occupants' comfort, industrial buildings have other vital factors that must be considered, such as environmental impact and energy consumption. The movement of contaminants (e.g., dust, fumes, vapours, aerosols, etc.) depends on the source shape and temperature, which are classified as diffusion contaminants sources, buoyant sources, and dynamic sources. Commonly, an industrial building is equipped with a general ventilation system, a local ventilation system, or a combination of both. However, due to the variety of industries producing a wide range of contaminants, special attention is required to employ the appropriate system. Thus, this study aims to address common types of industrial ventilation systems and new innovative designs such as spray local ventilation, vortex ventilation system and other types. Ventilation evaluation including common indices to assess the performance of the system including capture efficiency and Air change per hour as the most common indices for local ventilation and general ventilation.
