This course programme includes ductwork types & characteristics, sizing, velocities, diffuser grille & fan connections, bends, dampers, attenuators, system layout balancing and noise.
- Duct Sizing Methods: Relationship between volume, size, air velocity and resistance
- Static, velocity and total pressures and pressure diagram
- Constant friction, constant velocity and static regain methods
- Velocity Limits: Limiting velocity for noise in different applications
- Duct Distribution Systems: Tree system (mains, sub mains and branches)
- Octopus (modular plant)
- Ring main
- Plant Connections: Inlet and outlet connections to centrifugal and axial fans
- Connections to terminals
- Flexible connections
- Room Air Distribution: Limits for different terminals
- Effect of supply temperature
- Perforated ceilings
- Displacement ventilation
Ductwork Types: Circular and rectangular
- Damper Types & Characteristics: Opposed blade, parallel blade, iris and other methods of controlling volume
- Noise: Brief introduction to noise including sound power and sound pressure, Noise criteria and noise rating and Control of noise
- Attenuator: Square end, round end and aerofoil. Positioning of attenuators
- Commissioning: Brief introduction to good commissioning practice, Design requirements to facilitate commissioning and Interpretation of commissioning records
The delegates will gain the attention to detail at design stage to minimise problems when commissioning.
Who Should Attend
Delegates should have had a formal academic (B Eng.) followed by a few years of experience or have been working as Technicians/draftsmen/Cadd operators.
