Presentation Summary
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.
Speaker Bio
Dr. Kishor Khankari, Ph.D. is President at AnSight LLC in Ann Arbor, MI. He provides engineering solutions and insights through Physics based simulations and analyses. Kishor has several years of experience in providing optimized HVAC solutions to a wide variety of applications involving external wind engineering, plume dispersion, smoke exhaust, displacement ventilation, natural ventilation, radiant heating and cooling, and indoor air quality and thermal comfort optimization for office spaces, patient rooms, operating rooms, cleanrooms, justice facilities, data centers, and warehouses. Dr. Khankari has developed a patented technology of a wind band design of exhaust fan assembly systems. He has developed several easy-to-use analytical software tools which are regularly used by design engineers in a variety companies including those in HVAC industry, critical facilities, and automotive industries.
A noted expert in his field, he has a Ph.D. from the University of Minnesota and has been regularly published in several technical journals and trade magazines. Dr. Khankari is an eloquent speaker and has made several presentations worldwide on topics related to design and optimization of HVAC systems at various technical conferences and professional meetings.
Dr. Kishor Khankari is a Fellow member of ASHRAE. He is a recipient of ASHRAE Exceptional and Distinguished Service Awards. He is the past President of Detroit ASHRAE Chapter. He is past Chair of ASHRAE Technical Committee TC9.11 Clean Spaces and Chair of Research Administration Committee (RAC) at national level. He is currently leading a new ASHRAE Multi Task Group (MTG) on Air Change Rates.
Distinguished Lecturer Program
The purpose of the ASHRAE Distinguished Lecturers (DL) Program is to provide ASHRAE Chapters with lecturers equipped to speak on relevant subjects of interest to ASHRAE members and guests without incurring huge costs by covering travel expenses to and from the host city. Distinguished Lecturers are nominated by ASHRAE members and presentations are evaluated. The Distinguished Lecturer Program is supervised by the Chapter Technology Transfer Committee. For the 2018-19 Society Year, 195 visits are allocated to the 15 ASHRAE Regions. The CTTC Regional Vice Chair for each Region allocates visits to the Chapters.
