The outpatient department of General Hospital A was selected as the study building, and the particle count of infectious microbes was analyzed according to the three outdoor air induction ratios. In the recirculation mode (OAir: 0%), the numbers of infectious microbe particles in the waiting room and examining room were not reduced by the direction of indoor airflow and recirculation. In the general air-conditioning method (OAir: 30%), the reduction in the numbers of infectious microbe particles in the waiting and examining rooms were slow due to lack of ventilation and congestion of indoor airflow, and slightly affected the doctor’s office through the corridor. In the case of 100% outdoor air system (OAir: 100%), the number of infectious microbe particles was reduced rapidly compared with the cases of recirculation and general air-conditioning, and it was shown to be suitable for preventing airborne infectious microbe diffusion. When the waiting room pressure was adjusted to -1.5pa based on the general air-conditioning method, airflow merged from the examining room toward the waiting room, increasing the number of infectious microbe particles in the waiting room but not leading to external diffusion and intra-diffusion. When the examination room pressure was –1.5pa, airflow was stagnated in the direction of the corridor or the nursing desk instead of air being induced from the waiting room to the examination room, which was not suitable for indoor airflow induction.
