Abstract Modern buildings, shopping malls, and supermarkets nowadays rely on
centralized systems to maintain the optimal air and water temperature. These units
often placed in the open areas affect the environment by generating a significant
amount of noise which influences acoustical comfort in residential areas, and reduces
the productivity of the people working in nearby office buildings. The main engineering challenge in performing the noise control of heating/cooling units is that a
significant amount of air has to be provided for its subsystem cooling, while at the
same time noise must attenuate. Here, a practical approach based on the simulation
is investigated, noise reduction system implemented and results observed. Combination of the custom made adsorption elements and the chosen geometry based on
simulations showed the promising results that can be applied to various types of
HVAC systems.
