A chiller system achieved a significant noise reduction of 25 dB, demonstrating effective sound management strategies.
Key metrics like transmission loss (TL), reflection coefficient (RC), and acoustic specific impedance (Z) were essential in reducing noise levels.
Modeling techniques, including fluid-structure interaction and boundary element method (BEM), were employed to analyze noise reduction effectiveness.
Results indicated a drastic drop in compressor vibrations to 1/20 and discharge pulsation pressures to 1/100, underscoring effective design choices.
