The biggest savings can be achieved by replacing forward curved double inlet centrifugal fans with single inlet backward curved ‘plug’ fans or EC fans. These will usually have a smaller motor for the same duty requirement, and with inverter fan speed control or built in electronic control on EC fans there is the possibility of demand led control of the ventilation, or accurate commissioning with the minimum power requirement. Night setback and air quality monitoring are possible with inverter installation providing major opportunities for energy saving.
AHS Specialist Services can provide a spreadsheet illustration of the energy saving with the introduction of ‘plug’ fans into AHU’s.
