GenRoom Acoustics: plant-room noise and ventilation in one workflow

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

1. Project & scope — room type and the noise paths to evaluate.
2. Input documents — drawings, equipment catalogues, specification; checks what is missing.
3. 3D model & layout — import STEP or place engines, louvres, silencers and radiators.
4. 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).
5. 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).
6. Detailed simulation — CFD (OpenFOAM) and fine-mesh acoustics requests; results come back to the request table and the ERP design folder.
7. 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.
