A CFD ANALYSIS OF VENTILATION SYSTEM OF LAVATORY IN OFFICE BUILDING
In present lavatory in Japan, the following are being tried for the purpose of further improvement in the amenity : washable seat, heated seat, deodorization with function stool. In this study, the examination was carried out on the usefulness of the local ventilation system using CFD analysis method on the assumption of the lavatory in office building. In the analysis, it is examined by changing the volumetric exhaust flow rate on ceiling ventilation, local ventilation and ceiling and local ventilation combined use. On each case, it is examined by changing air ventilation balance and outlet position. The result showed that the local ventilation could reduce the indoor pollutant quality concentration in comparison with the ceiling ventilation at little ventilation air volume. And, it was shown that diffusion range of the pollutant to the near human head was reduced.
