چکیده

During the normalization phase of COVID-19 epidemic, it is gradually reverted to use building space, especially for office. Prevention airborne pollutant has emerged as a major challenge. Ventilation strategies can mitigate spread disease in indoor environment, such increasing ventilation rate, modifying mode, etc. The larger rate lead higher energy consumption may not effectively reduce infection risk. potential modes control should be explored. Furthermore, necessary adopt low-cost strategies, physical barrier, increase prevention efficiency while combining system. This study was investigate impact barrier on particles and risk an office with sufficient then compare different including mixing (MV), zone (ZV), stratum (SV) displacement (DV), optimal one. simulation model mainly used this work validated by experiment show good agreement prediction. results showed that (1) SV greater performance mitigating than MV, ZV DV, minimum 13%; (2) height at least 60 cm above desk surface needed prevent transmission viruses reduced about 72%. provide reference development well interventions public space oriented COVID-19.
