Fans

AHPHX Compact air handling units have supply andreturn air backward curved centrifugal plug typefans, direct driven by high efficiency EC motors.

This method of scroll free fan produces an optimallow loss flow of air through the impeller so thereare no longer any drastic cross sectional changes.

Fan Inlet Flow grids… By fitting an inlet flow grid to the supply fan it ispossible to achieve significant noise reductionfrom the fan.

The noise reduction is predominantly lowfrequency decay (i.e. 63Hz, 125Hz, 250Hz), whichcan help offer significant sound power loss. Thissound power loss is created by the reduction inturbulence hitting the rotating blades, with tonalfrequency components, known as impellor noise ortonal noise.

Tonal noise consists of the blade – passing noiseand its harmonics. The frequency of the blade –passing noise can be calculated as the sum of thefan speed and the number of blades.

A flow-grid fitted to the inlet of the fans willsignificantly reduce the low frequency noisegenerated disturbance. The vortex is split whenimpacting the grille as it is considerably weakenedwhen it flows through the flowgrid.

Sound pressure is reduced, particularly the lowfrequency. The chart below indicates the powerloss in octave bands.

Flowgrids

Dampers

All dampers are constructed from an aerofoilsection double skin aluminium blade profile withedge, blade and side seals to offer low leakage.

The blade rotation is performed by rigid nylon cogswhich operate out of Air Stream. The damperoperating mechanism is connected to an optionalfactory fitted and pre-wired actuator via a squarebrass drive shaft.

Thermal Insulated Dampers

Thermally insulated blades can be provided forfresh air and exhaust air shut off dampers whichadd protection to filters and coil freezing.

Electric Heater

Thermal Insulated Dampers

Fans

Motors operate via a 0-10V DC output from themotor, it provides infinitely variable speed control.

Backward curved scroll free fans are quiet runningwith optimised airflow through the impeller, givingsignificantly reduced tonal noise.

Multi fan wall arrangements are used to achievehigher air flow performance and efficiency.

Accreditation… In partnership with Salford University acoustictesting laboratory a range of composite acousticpanels have been designed and tested.To obtain the true casework noise breakout, theframe and panel assembly have to be tested with alarge enough area sample to give a truerepresentation of AHPHX Compact casework.In practice the framework can leak sound whichwill flank the panels. Therefore the frame must beacoustically insulated to the same standard as thepanels.

Assembling test frame and panels

Test set up during testing programme

Certification…All acoustic SRI tests arecertified by Salford UniversityTest Laboratories to BS EN ISO10140-2(2010) – Report No’s1429 & 2060.

Attenuator Performance…Insertion losses for different attenuatorlengths serving atmospheric and systemside, for both integral or bolt on style.

Attenuation… All attenuators are provided to match theAHPHX Compact unit and can be supplied as anintegral or bolt on arrangement. This isrecommended to prevent noise flanking theattenuators, or the need to acoustic lag theductwork.

If the attenuators are positioned away from thenoise source (i.e. AHPHX Compact), then ductnoise breakout will occur, unless the duct isacoustically lagged to the same high standard,as the AHPHX Casework.

Option 1

Splitter absorbers inbuilt into the AHPHX Compactunit Casework which provides a uniform caseworkappearance, as shown on Figures 2 and 3 on page 47.

Option 2

Duct style attenuators with bolt on arrangement asshown below. The splitter absorbers are containedwithin a galvanized flanged sheet steel duct. Purposedesigned bolt on type attenuators have mezz ordolby flanges to match the air handling unit frames,and can have optional inlet/outlet fairings.

Acoustic Louvre…As an option to attenuators or attenuator cowls onthe air intake and discharge of external AHPHX airhandling units, acoustic louvres can be used as analternative method of reducing the atmosphericside air noise. Four different depths are availablewith the noise reduction, dimensions and weightsas shown on pages 51 and 52.

Acoustic louvres have four depths, offering adifferent insertion loss for each depth. The chart onpage 51 gives the noise reduction for each depth300mm, 400mm, 500mm, 600mm.

External AHPHX compact with inlet and exhaust acoustic louvres on a Type 4 configuration unit (Fig 1).
