Ventilation Performance of Residential Kitchen Range Hood- Capture Efficiency of Island Hood

An island hood, which is often installed in anisland kitchen, is an exhaust range hoodmounted on a ceiling independently. Thecapture efficiency of the island hood is obtainedby experiment and CFD analysis. Examinedparameters are heat input, exhaust airflow rate,mounting height of the hood, and withlwithout abaffle plate. The Experimental results indicatethat the effect of the baffle plate is achieved inthe case of large exhaust airflow rate or smallheat input. Results of CFD analysis are higherthan that of the experiment in the all cases.
