Performance Data Guide

The data on the following pages has been derived from tests undertaken at a third party acous�c test facility in

accordance with BS 4856: Part 4: 1997 “Determina�on of sound power levels of fan coil units, unit heaters and

unit coolers using reverbera�on rooms”.

A standard 200Ø spigo:ed fan coil unit was mounted in Reverbera�on Room 1 then ducted with 1000mm long

solid circular galvanised sheet steel ducts to a dividing wall / plate and into Reverbera�on Room 2. If solid

ducts are replaced by flexible ducts the discharge sound power levels (Lw) will reduce by:

Acous0c Reduc0on to Lw 125 250 500 1k 2k 4k 8k Hz

1000mm flexible duct 4 5 9 11 10 8 8 dB

Tes0ng Procedure

Guide NR levels are based on a number of assumed parameters and a typical office installa�on. We have listed

these parameters below, should these parameters not be applicable for a par�cular applica�on, then a

detailed acous�c assessment will be required.

Fan Coil Unit Size Room Size

Reverbera0on Time

Sizes 1 & 2 20m² 0.35 s

Sizes 3 & 4 30m² 0.45 s

Size 5 56m² 0.60 s

Ceiling Height

2.7m

2.7m

2.7m

The Guide NR level assumes that a single fan coil unit will be installed within a 600mm deep ceiling void above

a room with the aforemen�oned characteris�cs, and serving 1000 x 100mm slot diffusers with 50% free area.

A correc�on to the Guide NR level should be made where more than one unit is present in a room space.

Return air grilles should be located at least 1.5m from the fan coil inlet.

Representa�ve guide NR levels can be provided for Pres�ge units, based on a typical hotel bedroom

applica�on.
