| Abstract |
In order to analyze the thermal performance of a hydronic radiant floor heating system, a hydronic analysis as well as a thermal analysis should be conducted for more accurate results. Room air temperature (determined by thermal simulation) and is influenced by water flow rate (calculated by hydronic simulation), and vice versa. Nevertheless, thermal and hydronic analysis have been conducted separately because of the difference in analysis method. In general, a thermal simulation used to assumed constant flow rate to each room. In this study, the conditions for coupling thermal and hydronic simulation together were investigated. Based on these conditions, a coupled model was developed using Matlab/Simulink. And a thermal simulation for a multi-zone residential building was complemented by using the developed a coupled model. |
