June Lunch Meeting - Airflow Managment for Laboratory Facilities

TOPIC: Airflow Management for Laboratory Facilities

    BY: Distinguished Lecturer Kishor Khankari

(PLEASE NOTE WE ARE BACK AT BYRON'S)

Presentation Outline: 

Air is the primary carrier of heat, moisture, and contaminants in laboratory facilities. The flow path of supply air plays an important role in determining the air velocities, air temperatures, concentration of contaminants, and path of contaminants in laboratories. Often high airflow rates or air change rates per hour (ACH) for laboratory spaces are specified to cover the risk of chemical exposure. Although high supply airflow rates can reduce the overall concentration of contaminants  it may not ensure uniformity of concentrations at a low diluted level. Importantly, locations of high concentration , especially those in the breathing zone of occupants can pose potentially higher exposure risk. This presentation will focus on the importance of HVAC configuration on airflow distribution and flow path of contaminants in laboratories . In addition, this presentation will cover basics of air ventilation for laboratories and flow dynamics of fume hoods.
