CFD Analysis and Accuracy Evaluation of Advanced Displacement HVAC System in a Large Factory Space

Abstract

Computational fluid dyanmics (CFD) simulations are widely performed in the design of heating, ventilation, and air conditioning (HVAC) systems. The swirling induction type (SWIT) displacement HVAC system has been proposed as more efficient ventilation system than ordinary displacement ventilation systems. We develop a CFD simulation model of an existing large factory equipped with the SWIT system and then numerical results are validated by on-site measurements at the large factory. It is confirmed that the developed simulation model is an effective and reasonable approach to predict the ventilation performance at design phase.
