STULZ and Merford Develop Integrated Noise Reduction System for Chiller in Italy

STULZ and Merford have introduced a noise reduction system for a new chiller designed for a project in Valeggio sul Mincio, Italy. This system aims to meet strict noise regulations while ensuring efficient cooling. The project required compliance with a maximum nighttime noise limit of 80.2 dB(A). Extensive acoustic testing was conducted under realistic conditions, utilizing advanced modeling and measurement techniques, confirming that the system met regulatory requirements.

Acoustic validation was conducted per EN ISO 9614-2:1997, with a detailed analysis performed using SoundPLAN software. Two noise reduction concepts were tested, both involving steel frame constructions with integrated acoustic dampers. The effectiveness of the system was confirmed through comparative measurements, showing compliance with the stringent noise regulations.
