Numerical Simulation on Mechanical Ventilation for Odor Removal Efficiency in a Bathroom
This paper numerically studies the effect of ventilation rates and bathroom equipment locations on the odor removal efficiency in a modeled bathroom. Simulation results agree well with previously published experiments such that moving exhaust air vent from ceiling to wall and addition of one supply fan would significantly improve odor removal efficiency. In addition, by doubling the area of exhaust vent under a fixed air change rate, odor removal efficiency (ORE) can be greatly enhanced to 16-30% while previous experiment showed only a moderate 4% increase in ORE when doubled the flow rate of supply air.
