Abstract： For traditional bathroom ventilation systems,the exhaust air vent is arranged in the ceiling of the bathroom.In this study,a bathroom mockup with a hybrid ventilation system, which comprises ceiling-supply and wall-exhaust air vent,is efficiency.The toilet and urinal dummy are arranded in the bathroom.Ceiling-supply air vents are installed in nine locations to evaluate the airflow pattern and temperature distribution of the ventilation system.The influences of ceiling-supply air vent arrangement and ventilation flow rate on the air flow fields and thermal efficiency are examined using both experimental and computationl fluid dynamics(CFD) methods,In the experiments, the velocity and temperature levels are monitored at 18 measurement points within the bathroom.The signals obtained are transmitted through a chip module in serial communication to a PC computer for further analysis.The simulation results are compared with experimental findings.Both experimental and simulation measurements show that the flow field and the ventilation efficiency are affected apparently by the arrangement and the ventilation by the ceiling-supply system.According to the experimental and simulation results a quantitative assessment of odor removal and ventilation efficicncy in the bathroom is addressed in this paper.
