ICE BALL 내장 빙축열조내 열유동 특성 연구

The study on ice thermal storage system is to improve total system performance in actual air-conditioning facilities. To obtain the high efficiencies in ice thermal storage system, the improvement of thermal stratification is essential, therefore the process flow must be piston flow in thermal storage tank. Ice packing factor is batter on condition that the inflowing temperature is law, the flow direction in the thermal storage is upward and the cylinderical thermal storage type is used. This result shows that cylinderical ice storage tank has batter storage capacity than rectangular type in case of the same porosity.
