SPEAKER Kishor Khankari, Ph.D., Fellow ASHRAE, Distinguished Lecturer,
President, AnSight LLC.
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 CFD analysis. 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 has delivered more than 125 DL presentations worldwide on topics related to design and optimization of HVAC systems and made several presentation at various technical conferences and professional meetings.
Dr. Kishor Khankari is a Fellow member of ASHRAE. He is currently serving on ASHRAE Board as a Director-at Large. He is a recipient of Louise & Bill Holladay Distinguished Fellow Award, ASHRAE Exceptional and Distinguished Service Awards. He is the past President of Detroit ASHRAE Chapter, past Chair of ASHRAE Technical Committee TC9.11 Clean Spaces, and past Chair of Research Administration Committee (RAC). He is a voting member of Technical Committee TC9.10 Laboratory Systems and TC5.3 Air Distribution. He is a voting member of Standards committees SPC241: Control of Infectious Aerosols and SPC129: Air Change Effectiveness. He is also leading a Multi Task Group (MTG) on Air Change Rates.
Design and Analysis of Natural Ventilation Systems
A good design of a natural ventilation system maintains harmony between the local climates, space sensible heat loads, and the design of operable openings (windows). Poorly designed systems can perform miserably even in the best climatic conditions. Several factors such as building orientation, building massing, effective opening areas and their locations, relative height differences, internal heat loads, furniture and seating arrangement within the occupied spaces can affect the performance of natural ventilation systems. This presentation will discuss basics of natural ventilation and with the help of case studies demonstrate how basic analyses can help predict number of hot and comfortable hours for occupants and how to optimize the performance of natural ventilation designs.
Stratified Air Ventilation Systems
Displacement ventilation systems which are also referred as “stratified air distribution systems” work on the principle of thermal buoyancy – hot air due to lower density rises above the cold air. Stratified distribution systems are becoming popular due to their ability to provide better indoor air quality with low energy demand. Stratified air distribution systems come mainly in two flavors – traditional displacement ventilation (TDV) systems and the under floor air distribution (UFAD) systems. This presentation will cover the basics of stratified air distribution systems and discuss various design and operational parameters that affect their performance.
