This study investigated indoor/outdoor ozone concentration ratio for infiltration, mechanical ventilation and natural ventilation. The following conclusions can be obtained from the study:
The simple model for estimating ozone I/O ratio was tested by measuring indoor/outdoor ozone concentrations and air exchange rates at two test chambers and an office space and by using the surface ozone removal rates obtained from the literature. Within the range of our study, the model can predict the ozone I/O ratio within 20% of error.
The model was then used to estimate quantitatively the ozone I/O ratios for different ventilation routes. Based on the ventilation rate and surface removal rate data collected from the literature, the most common ozone I/O ratio was 0.09, 0.19, and 0.47 for infiltration, mechanical ventilation, and natural ventilation, respectively
