6                                      CHAPTER I INDUSTRIAL AIR TECHNOLOGY—DESCRIPTION
                      4. Physical Fundamentals
                         This chapter introduces the important topics of fluid flow, properties
                      of gases, heat and mass transfer, and physical/chemical characteristics of
                      contaminants. The aim is to assist all engaged in industrial air technology
                      in understanding the physical background of the issues involved,

                      5. Physiological and Toxicological Considerations
                         This chapter introduces fundamentals of human physiology and health re-
                      quirements relevant to the control of indoor environment within industrial
                      buildings.

                      6. Target Levels
                         The chapter presents a new concept called target levels. It outlines the role
                      of target levels in the systematic design methodology, the scientific and techni-
                      cal grounds for assessing target levels for key parameters of industrial air tech-
                      nology, and the hierarchy of different target levels, as well as some examples
                      of quantitative targets.
                      7. Principles of Air and Contaminant
                      Movement inside and around Buildings
                         This chapter presents the basic processes of air and contaminant move-
                      ment, such as jets, plumes, and boundary flows.

                      8. Room Air Conditioning
                         This chapter describes the room air conditioning process, including the in-
                      teraction of different flow elements: room air distribution, heating and cooling
                      methods, process sources, and disturbances. Air handling equipment, including
                      room air heaters, is discussed in the form of "black boxes" as far as possible.

                      9. Air Handling Processes
                         This chapter describes the fundamentals of air handling processes and
                      equipment and gives answers to questions relating to the theoretical back-
                      ground of air handling unit and ductwork dimensioning and building energy
                      systems optimization.

                      10. Local Ventilation
                         This chapter describes the aerodynamic principles, models, and equations
                      that govern the flow and the contaminant presence and transport in a desig-
                      nated volume of a work room. The purpose of local ventilation is to control
                      the transport of contaminants at or near the source of emission, thus minimiz-
                      ing the contaminants in the workplace air.

                      11. Modeling Techniques
                         This chapter describes calculation models for building energy demand and air
                      flow in and around industrial buildings. Special attention is paid to simulation of
                      airborne contaminant control.
                         Four methods for industrial air technology design are presented: computa-
                      tional fluid dynamics (CFD), thermal building dynamics simulation, multizone
