Numerical Simulation of Displacement Ventilation in a Gymnasium in a Large Space Building
MetadataShow full item record
Since athletes' records can vary greatly depending on air velocities in sports halls, airflow patterns have played a very important role in HVAC design in gymnasiums. HVAC designers and researchers have paid more and more attention to this problem. However, there still remains a lot to do in providing a suitable airflow pattern for competitions, with less energy consumption. Recently the displacement ventilation (DV) system has been adopted in northern Europe. It is used in large spaces such as gymnasiums, but is still not commonly used in China. By using BusinessSoft, we analyzed the airflow, thermal comfort, the effects of ventilation and other parameters on the HVAC in two main zones of the gym, the competition zone and the stands zone. Results indicate that the DV can meet design requirements.
