When sizing ventilation ductwork, the maximum air velocity should be limited to avoid noise whilst minimum velocities must be maintained for effective particle suspension in fume extract and local exhaust ventilation (LEV) systems.
When sizing heating and chilled water pipework, the maximum water velocity should be limited to avoid noise and prevent erosion or corrosion damage occurring and the minimum water velocity should be sufficient to prevent suspended matter settling out leading to system deterioration.
Install a deaerator at the system hottest point: outlet from a boiler or inlet to a chiller.
Furniture, fixtures and equipment are categorised into 5 groups to identify supply and fit responsibility.
