| Abstract |
The objective of this study is to analyze the performance evaluation of the Radiant Floor Cooling through field experiments. The experiments are performed to evaluate the performance of the radiant floor cooling and confirm the possibility of continuous cooling through the actual field experiments, moreover, analyze specific characters of the radiant floor cooling system according to varying the load conditions which is able to happen to field. Experiment results show that the permissible ambient temperature range was determined by cooling load calculations, and the cooling capacity was calculated from steady-state heat transfer equations. Under these conditions, experiments were performed for an actual apartment building assuming two occupants. During 80% of the cooling period, radiant floor cooling provides sufficient and continuous cooling. The results of analyzing the indoor thermal environment in the actual apartment building show that the set room air temperature is maintained while the floor surface temperature, vertical temperature distribution and PMV remain within the comfort range. |
