Ventilation Effectiveness of Ceiling-Supplied Displacement Ventilation System for Office Room (Part 2) A Parametric Study on the Indoor Environment Examined by CFD Analysis

We propose the ceiling-supplied DV system. In this system, inlet and outlet are both set at the ceiling, so improves design and construction issues. In this paper, the result of the CFD analysis was compared with the experimental result shown in the previous paper to prove the validity of the result of CFD analysis. Also, the impact of supply airflow rate, supply air speed and heating wall assumed skin load of the building in summer on the temperature and contaminant concentration profiles is studied by CFD analysis to investigate the factors influencing the indoor environment under this ceiling-supplied DV system.
