Abstract

Low temperature heating and high temperature cooling systems have proven to be an energy efficient solution for conditioning building. Thermally activated building system (TABS) has become established as innovative systems for radiant heating and cooling system, and utilizes the building structure to store the thermal energy, reduce the peak loads and decrease primary energy demand in buildings. However, room acoustic performance should be of concern for the use of TABS. For this, free hanging acoustic panels (FHAP) were generally designed to reduce the overall sound intensity and reverberation time. This study aims to investigate the long-term effect of FHAP on cooling performance characteristics of TABS through two dimensional heat transfer simulation. In results, the coverage ratio up to 50% of the ceiling area by using horizontal FHAP has no significant influence on the cooling performance characteristics. And the vertical FHAP does not affect the cooling capacity from the ceiling at all.
