1.1 INTRODUCTION—WHY ATTENTION TO INDUSTRIAL AIR TECHNOLOGY?

A young scientist said, "I have never seen a complex scientific area such as in-
dustrial ventilation, where so little scientific research and brain power has
been applied." This is one of the major reasons activities in the industrial ven-
tilation field at the global level were started. The young scientist was right.
The challenges faced by designers and practitioners in the industrial ventila-
tion field, compared to comfort ventilation, are much more complex. In indus-
trial ventilation, it is essential to have an in-depth knowledge of modern
computational fluid dynamics (CFD), three-dimensional heat flow, complex
fluid flows, steady state and transient conditions, operator issues, contami-
nants inside and outside the facility, etc.
In all ventilation, the condition of the indoor environment, called indoor
air quality (IAQ), and the exposures for the occupants are important. In in-
dustrial facilities, the contaminant emission rates may be 10-100 times higher
than in nonindustrial facilities, but for many contaminants the IAQ levels may
