FORUM 2 (INTERMEDIATE): Air Change Rates: Friend or Foe?
Track: The Great Debate
Sponsor: 09.11 Clean Spaces, TC 9.06, TC9.10
Chair: Kishor Khankari, Ph.D., Fellow ASHRAE, AnSight LLC, Ann Arbor, MI
Air Change Rates (ACR) or Air Changes per Hour (ACH) are often specified in many standards, codes and design guidelines as supply airflow requirements for healthcare, cleanrooms, laboratories and other similar facilities. A group of people who support such philosophy think it has been working successfully from several decades in making these spaces safe, comfortable and healthy. Another group thinks this legacy practice has a little scientific basis and is a burden on energy efficiency and cost of operation of HVAC systems. This session has an open debate on this issue. Active participation is required from the attendees.
