Abstrakt

The purpose of this study is to evaluate the indoor environmental conditions for comfort and cooling performance of the capillary tube using geothermal energy. The experiments are performed to evaluate the cooling performance of the capillary tube radiant cooling and to confirm the possibility of continuous cooling through the actual field experiments. The results of this study are as follow. In peak load, the Capillary Tube Radiant Floor Cooling System using geothermal energy can be satisfied with the indoor setting temperature without other heat sources. The set room air temperature is maintained while the floor surface temperature, vertical temperature distribution and PMV remain within the comfort range.
