CFD Simulations – Efficient Tool for Designers of Industrial HVAC Applications

Abstract

The aim of this study is to design industrial ventilation in the production hall. With respect to the many parameters which influence the appropriate proposal of industrial ventilation that need to be considered, there is a good chance for miscalculations when design the industrial ventilation. Especially when the heat loads from technology threaten the stability of construction of the building. There are two different ways of solution of aeration in the aluminium plant. There is only a natural ventilation using outside air in case of melting of aluminium and an adiabatic cooling for air inlet combined with natural ventilation. The results and practice has shown, that to use only an outside air is not sufficient and the temperature in the hall is really very high. Adiabatic cooling decreases the air inlet temperature in the production hall and improves the working conditions. A thermovision mapping of the technology was used prior to start the CFD modelling. The simulation emphasize the important effect of design and location of different elements on the functionality of ventilation proposal.
