Mitigating Disease Transmission with Germicidal UV-C

When:  Apr 21, 2021 from 2:00 PM to 3:00 PM (ET)

This presentation will briefly discuss the basics of Germicidal UV-C technology and its ability to inactivate infectious diseases, such as MRSA, TB (drug-resistant), Ebola, SARS, MERS and even the flu. As the SARS-CoV-2 virus evolved into a worldwide pandemic, UV-C has become a go-to technology in the battle against the spread of COVID-19.

This presentation will provide engineer-level guidance for the use of UV-C energy to continuously reduce and even prevent the spread of dangerous microbes in HVAC systems and the circulation of infectious pathogens in airstreams. It will also examine the operating conditions that increase or decrease the required minimum UV-C dose for pathogen inactivation, including UV-C fixture placement, air temperature, air velocity and AHU material reflectivity. The presentation will also review ASHRAE’s position documents relative to the transmission of airborne pathogens, as well as maintaining HVAC maintenance and efficiency.

Learning Objectives:

  1. Basic understanding of germicidal ultraviolet light and how it is used to mitigate airborne pathogens.
  2. How to properly apply and size Ultraviolet systems for HVAC equipment.
  3. Learn how to apply Upper Room germicidal fixtures for source control of airborne pathogens
  4. Updated information from ASHRAE's epidemic task force on COVID-19.
