4 CHAPTER I INDUSTRIAL AIR TECHNOLOGY-—DESCRIPTION
1. Industrial Ventilation
Air Conditioning Systems
Air conditioning systems control air quality and thermal environment for
both human occupancy and processes.
General Ventilation Systems
In general ventilation systems some indoor air parameters are controlled
only partially. Target levels are usually lower than for air conditioning.
Local Ventilation Systems
Local ventilation systems are used for local controlled zones. These systems
are based on local capture of contaminants.
Process Ventilation Systems
In process ventilation the target is to maintain defined conditions to ensure
process performance (e.g., paper machine hoods).
2. Process Air Technology
Cleaning Systems
Cleaning systems are used to remove contaminants, clean the resulting
fluid flows, and collect materials before discharge of exhaust air.

Pneumatic Conveying Systems
Conveying systems are used to transport captured pollutants from processes
to a collection point.

Drying System
Drying systems are used to remove moisture, gases, and vapors from a
product.

Safety Air Technology Systems
Air technology systems may be designed for control of smoke during fires
or to reduce risks of explosions.

1.4 DESIGN GUIDEBOOK (DGB)

1.4.1 History and State of the Art
A group of international specialists in the area of industrial ventilation have
decided to write a handbook (the "Bible") of industrial air technology. The
book, Industrial Ventilation Design Guidebook (DGB), will be written as a
major cooperation effort. People and organizations from the following
countries participate in the work of one or more international actions within
the scope: Belgium, Canada, Czech Republic, Denmark, Finland, France,
Germany, Hungary, Italy, Japan, the Netherlands, Norway, Russia, Sweden,
Spain, Switzerland, the U.K., and the U.S.A. Australia and Poland are also
interested.
