Aims of an Air-Handling System, Including the Unit and Ductwork
The main objectives are
• Contaminant removal from the indoor space and associated processes
• Supply of safe cleaned and/or treated air for the occupied spaces
• Control of thermal and pressure conditions in treated spaces in a safe, reliable, and energy-efficient manner
Aims of ductwork design are
• Transport of air to and from treated (conditioned) spaces
• Distribution and control of airflows to and from the treated spaces with optimum life-cycle costs.
The air-handling processes should be arranged to take into account the thermal, aerodynamic, and acoustic factors; air quality; moisture control; and cleanliness and other hygiene aspects.
These issues relate certain requirements of the layout of the air-handling system and individual units, including the question of whether to select centralized or decentralized systems, and the number of units required in the building.
