Air Handling Systems
Air handling may be defined as the ‘science of moving air from one point to another’. The question then, of course is, why would we do this? There are many uses of moving air in both industrial and building scenarios:
• heating and cooling for comfort;
• ventilation of living spaces;
• fume extraction;
• dust extraction; and
• transfer of materials
In its very simplest form, an air handling system could comprise a propeller type fan operating in open space, directing a flow of air at an object or objects. This could be to provide cooling or to dispel fumes or to promote burning. At the other end of the scale an air handling system could comprise many components such as inlet louvres, an air handling unit (AHU), fans, a complex ductwork system, control dampers, various types of terminal unit and outlet louvres etc.
