Eurovent 8/12 - 2008: Sound test method for ducted fan coil units

The purpose of this document is to describe the measurement method of Ducted Fan Coil Units sound power level, at speeds of choice with an available static pressure equal to 50 Pa at medium speed. The sound power levels are calculated in frequency bands from sound pressure level measurements in a double reverberation room. The test results describe the performance of the FC in the real condition of build installation where, as usual, the static pressure is fixed at medium speed.
