Optimisation of fan performance for both airflow and noise is a major activity
of Vipac's Fan Development Laboratory. Vipac maintains several Fan Test Rigs
which comply with the requirements of AMCA, ASHRAE, ARI, BS and AS Standards
for centrifugal, axial, propeller and ceiling fans. This Fan Development
Laboratory is the only independent NATA registered fan facility in the Asian-Pacific area.
Twin Reverberation Chambers, 21m in length, allow the simultaneous measurement
of radiated and discharge sound power levels whilst the availability of AMCA
nozzles, BS orifice plates or pitot traverse enable any flow rate to be measured
at any static duty point. The availability of almost limitless power (up to 400kW)
and test laboratories up to 60m in length enable almost any fan in commercial
production to be tested.
Fan design for minimum noise is a major thrust in the laboratory and analytical
methods such as CFD (Computational Fluid Dynamics) and axial fan design using
the R.A. Wallis methodology are widely adopted. Workshop facilities for
prototyping and a hot test environment at 250°C complete a comprehensive
support facility.
Projects have been undertaken for many of the regions fan manufacturers
in a wide range of applications - from forward curved impellors in fan
coil units to large jet fans and smoke exhaust fans in vehicular tunnels
and mineshafts.
