| Abstract |
The thermally activated building system (TABS) is a thermal storage that uses the concrete slab to reduce the peak cooling load. A radiant cooling/heating system is typically designed with consideration on a peak load in a steady state to size the capacity. However, the design of the TABS should consider the time-lag effect due to the high heat capacity of the concrete slab in an un-steady state. Temperature of the concrete slab cannot be changed instantly, which may cause overcooling, overheating and condensation. This paper analyzed the design method considering the un-steady state using building simulation for more effective application of TABS. In order to achieve the objective, applicable range of the load handled by TABS should be determined. And the design method to operate the TABS with steady supply water temperature and operation period is proposed. |
