Working environment in an automotive parts manufacturing factory with axial fan ventilation system

Axial fan ventilation system has been investigated in an automative parts factory, during summer. 54 axial were installed on ceiling. For the estimation of the improvement of working environment of the automotive parts manufacturing factory with the axial fan, the distribution of air velocity and temperature are investigated by experimental method. Besides, the surface temperature of the ceiling and windows is measured by thermal camera to investigate the thermal stratification. And in case of the axial fan operates, the air flow pattern in the factory is predicted by air flow visualization experiments. The results show an improvement of the IAQ after the axial fan ventilation system installation.
