The Combined Convection-Radiation air conditioning system using building structure is a system that combines the strengths of the TABS and convection systems. The purpose of this study was to investigate the specification of this system and determine its thermal performance. For the experiment, two concrete test specimens were prepared assuming this system and general TABS. The placement method for the pipes and the airflow conditions around the test specimens were varied, and a comparison of the changes in the thermal performance. This paper indicates the strengths and weaknesses of this system compared with general TABS.
