Project: Sound power measurements in free field according to norm UNI EN ISO 3746 accomplished in Fieni, Dâmboviţa County – Romania.
The source which was object of the measurements, is composed by an ORC unit based on thermodynamic cycle made up of organic fluid designated to the transformation of heat into work. The plant is situated inside a cement factory.
The ORC unit is placed inside an industrial space realized with steel supporting structure, metal sheet covering with only one layer, metal sheet vertical partitions and horizontal cement floor.
The aim of this investigation and the customer’s request, is the analysis of plant’s sound power level during the first start up but in determined points, for this reason the “intensimetric analysis” is chosen.
