환기시스템 급배기용 덕트설계 및 소음 예측 S/W의 개발

초록

As the indoor spending of time and awareness about interior air pollution have been increasing the issue of IAQ becomes important. To provide an energy-efficient ventilation we have developed a software which enables the design and analysis for duct layout by considering the pressure losses and the noise from a flow in the duct. We calculate the pressure loss in the duct using the friction coefficient of each duct segment and the various loss coefficient and predicted the noise levels generated with the characteristic spectrum in terms of the Strounal numbers. Also, we developed the software GUI for user's convenience called AeroVent that users can design the duct.
