Application of computational fluid dynamics to HVAC and indoor air environment design
Abstract
In the past, use of Computational Fluid Dynamics Technologies (hereafter CFD) waslimited to specialist engineers using supercomputers. However, as desktop computing power has
increased and software costs have decreased, CFD can now be routinely performed by ordinary
M&E engineers using commercially-available software packages on personal computers.
Over the same timeframe, customer demands during the design process of building
HVAC systems have become more sophisticated and complex, and communication between
customers and designers using drawings alone is often insufficient. As a result, CFD has become
an important visualization tool for indoor thermal conditions and airflow during the designprocess. CFD is just a computational simulation method based on limited input and configuration
data, which cannot represent real world situations, such as boundary conditions and otherinformation derived from past performance and experience. Nevertheless, as long as theselimitations are understood, CFD can still be very useful as an HVAC system design support tool.
In this report, several CFD application examples to HVAC system and indoor airenvironment design process are shown, and the final goal of this report is to show theeffectiveness of CFD to HVAC system designers who use CFD.
