Seminar 41 -- Displacement vs Mixing Ventilation: How to Use Them to Mitigate Indoor Virus Transmission

This product is a zip file that contains files that consist of PowerPoint slides synchronized with the audio-recording of the speaker, PDF files of the slides, and audio only (mp3 format) as noted.

The airborne transmission of viruses (including COVID-19) via aerosols is a reality that will affect the way ventilation systems are designed for years to come. This seminar evaluates the impact of mixed and displacement ventilation methods on mitigating indoor virus transmission for different indoor environments. Some novel improvements over the conventional design are also proposed to improve the indoor air quality.
