Ventilation is the mechanical system in a building that brings in "fresh" outdoor air and removes the "contaminated" indoor air. In a workplace, ventilation is used to control exposure to airborne contaminants. It is commonly used to remove contaminants such as fumes, dusts, and vapours, in order to provide a healthy and safe working environment.
3 74 factories. 75 This paper reports our approach of using a combination of CFD modeling with limited on-site 76 measurements to study the ventilation performance in factories. Using several examples, this 77 investigation shows that our strategy should help designers to streamline their ventilation system 78 design process while maintaining acceptable indoor environmental quality in factories.
The volume of fresh air (make up air) required for a proper ventilation of a space is determined of the size and the use of the space - typical the no. of persons in the space, if smoking is allowed or not and pollution from processes.
Sometimes planned, powered general ventilation is an integral part of a set of control measures, eg the welding of large fabrications in a workshop; Local exhaust ventilation. Local exhaust ventilation (LEV), or extraction, is an engineering control solution to reduce exposures to dust, mist, fume, vapour or gas in a …

Zhang et al., Aerosol and Air Quality Research, 16: 442–452, 2016 443 Rohdin and Moshfegh (2007)studied ventilation performance by using different CFD models in a packaging factory and demonstrated that the RNG k-ɛ model was the best.
Factories in the Industrial Revolution were cramped and contained spaces. Often times, they were built without windows or proper ventilation and as a result the machines would quickly cause the inside temperature of the factory to increase dramatically. All of this combined to create a …
ventilation conditions in the existing garment factories of Bangladesh in terms of indoor air quality, thermal comfort; and, potentially, emergency smoke removal. These studies suggest that a methodology to develop passive ventilation strategies within existing garment factories is feasible in this tropical climatic context. INTRODUCTION
Jan 30, 2017· In small workplaces like a small office, for example, doors and windows may well be sufficient to comply with the regulations but in larger premises like industrial factories, mechanical ventilation will be required. Factory Ventilation. When considering the ventilation in a factory environment, you need to consider a number of aspects ...
Jul 23, 2014· However, industrial natural ventilation is a viable alternative. The "Green", Energy-Free Alternative. Unlike an industrial roof exhaust fan natural ventilation uses no power to operate. Furthermore, it is low maintenance and it will keep your industrial, commercial or factory building comfortable without electric fans or an air ...
