Thanks to the new Belimo Fan Optimiser, fans can in future be controlled based on demand according to the damper positions of the downstream VAV units. Supply pressure regulation – presently the standard method – can thus be dispensed with and fan energy consumption cut by as much as 50%. Costs will be cut substantially and the convenience for users increased.
Unnecessary energy consumption
Until now, constant regulation of the fans has ensured that even the most inaccessible VAV unit receives sufficient supply pressure. Since the remaining units are provided with too much air as a result, they have to eliminate the excess pressure by closing the dampers. This means noisy operation, inferior control characteristics and a lot of unnecessary energy consumption.
Demand based system solution
Belimo MP technology allows fan output to be selectively controlled based on actual demand. The actual damper positions of the VAV controllers and the demand signals of the room temperature controller are transferred to the COU24-A-MP Fan Optimiser via the MP-Bus. They are then passed on to the fan control.
Energy and cost savings
The massive energy savings are a practical way to achieve better values with regard to the new EU energy efficiency directives. By additionally doing away with the costs for the pressure regulation system and significantly reducing wiring expenses through networking via the MP-Bus, this solution guarantees rapid payback – in new, retrofitted or renovated systems.
