Ability have invested heavily in a new Fan Coil specific acoustic test suite and various analysing hardware and software packages. All of our FCU ranges have been fully acoustically tested in the new facility in accordance with the Real Room Acoustic Test Procedure published by the HEVAC Association. Using room volume, reverberation and background corrections, the Sound Pressure Levels measured under test conditions have been converted to Noise Rating (NR) Levels. In addition to this, Sound Power Level calculations have been undertaken from Sound Intensity measurements made in accordance with ISO 9614-1:2009. These SWLs have been correlated and verified with testing at the Institute of Sound and Vibration Research, University of Southampton, to BS EN ISO 3741:2010, with further corroboration against testing at Sound Research Laboratory. Tests have also been conducted in the new suite in accordance with BS 4856:Part 4.
Full setup and details available upon request.
Thermal performance selections based on Summer: 23°C 50% RH / Winter: 21°C 50% RH
All testing performed using standard units, featuring integral discharge plenums with circular connections. Units are fitted with G3 filter media and (unless specifically mentioned) include heat exchangers with 12FPI fin pitch.
