Acoustic comfort and energy efficiency of air conditioning systems

Noise and acoustic environment conditions affect health, well-being and performance inside and outside of work and living spaces. Therefore, standards have to be met in buildings just as for the other room features light, climate and air quality. While energy-saving lamps and energy-efficient air conditioning systems are obvious considerable reserves still exist in the sound-absorbing components. They are obstacles to the air transport and the effort to overcome this resistance has to be provided in terms of energy by increased power of fans. Thus, in its optimized configuration lies potential for energy savings while improving the acoustic quality. The article analyses the acoustic boundary conditions taking into account the effects of energetic consequences in the use of silencers. Solutions for their design will be presented and demonstrated with examples of achievable energy savings.
