Abstract

Recently the application of a thermally activated building system (TABS) integrating with the HVAC system in the office has been proposed for energy efficient heating and cooling system. The aim of this study is to analyze the characteristics of indoor thermal environment and the heat dissipation characteristics of TABS according to the cooling operating condition of TABS in the office building. For this, a 2D transient heat transfer program (Bistra) was used to simulate the cooling operation of TABS integrated with HVAC system in office building. The result shows that intermittent nighttime operation using night-time electricity has the little difference of indoor thermal environment compared to the continuous TABS operation. In comparison of the water temperature control methods of TABS, it is preferable to change the set-point temperature intermittently compared to the outdoor reset control with respect to the daily surface temperature distribution, initial cost and maintenance.
