ANÁLISE DE UM SISTEMA DE VENTILAÇÃO NATURAL DE UM GALPÃO INDUSTRIAL

Abstract

An efficient ventilation system in the workplace is necessary to promote the thermal comfort of employees, enabling them to perform their activities efficiently and safely. The efficiency of a natural ventilation system in a building dependent on the number, position, type and size of openings for airflow as well as the combined action of wind forces and temperature differences between indoors and outdoors. The work environment always carries some types of risks, which may be physical, chemical, biological or ergonomic. The activities in environments with heat in uncomfortable level, although not characterized as unhealthy environments deserve attention because it affects the performance and efficiency of employees. This paper presents an analysis of a natural ventilation system of a medium sized industrial shed (960m2), used as a warehouse by a sanitation company of Minas Gerais. The operating efficiency of the current ventilation system was verified. The purpose of the study is to analyze the existing natural ventilation system, to verify the natural ventilation system due to wind action, due to the difference in indoor air temperature and the ventilation due to the combination of these two processes. Because it is a medium-sized shed and whose activity within it does not pose any risk to neighboring communities, all air removed from the interior of the shed can be released into the atmosphere without any prior treatment. For industrial activities that generate waste that may cause risks to neighboring communities and the environment, environmental licensing is required for its operation.
