Aeroacoustics in HVAC systems

Efficiency must not be loud

Ventilation systems, air conditioning systems, fans – they ensure comfort and a pleasant indoor climate. But often a topic goes unnoticed for too long: sound.

Aeroacoustics is the key to not only making HVAC systems efficient, but also quiet.

Noise caused by flow, turbulence and interaction with housing parts has a significant impact on acceptance – be it in the office, in the hotel or in the living area.

What we do:

• CFD-supported flow simulations for prediction and optimization of airways
• Design optimization of fan geometries and air ducts
• Balance between air performance, energy efficiency and acoustic comfort

General: With the help of a scale-resolving CFD simulation, the transient pressure fluctuations are mapped in such a way that the sound sources can be defined. This allows the identification and optimization of the sound generation. To take into account installation effects and to assess the frequency-dependent sound levels at certain locations, the sound propagation can be simulated after identifying the sources.

The goal: systems that not only work, but are hardly audible. Because: Good technology is quiet technology.
