Is there enough cooling air, and is it too loud? Every generator room, chiller plant and cooling tower raises those two questions. The Starduct engineering team answers them with GenRoom Acoustics — an in-house tool that brings calculation, simulation and documents into one seven-step workflow.
Seven steps
- Project & scope — room type and the noise paths to evaluate.
- Input documents — drawings, equipment catalogues, specification; checks what is missing.
- 3D model & layout — import STEP or place engines, louvres, silencers and radiators.
- Calculation — noise path from the source through the room, silencer and louvre to the receiver, with Starduct silencers and louvres from the Tool Hub (pressure drop, flow noise).
- Quick simulation in the browser — airflow and heat on the plan, sound waves through the louvre, sound field through the silencer per band 250–4,000 Hz (checked against FEM: within 1.1 dB up to 500 Hz, on the safe side at higher frequencies).
- Detailed simulation — CFD (OpenFOAM) and fine-mesh acoustics requests; results come back to the request table and the ERP design folder.
- Results & documents — technical report, presentation, calculation notes.
Example: Hanoi Parc, level-2 generator room. The detailed simulation showed uneven airflow between the supply silencers, and louvre bank LM-3+4 calculated at 78.1 dB(A) against a 78 dB(A) target — something a hand calculation could not reveal.
All simulation figures are calculated values, not tested, and are reviewed by a Starduct engineer before they reach the client.
