Study on Stratification according to Diffuser Shape of the Thermal Storage Tank in Integrated Energy

집단에너지 공급 축열조의 디퓨져 형태별 성층화 연구

The stratification effect was investigated with four different types of diffuser shape in a thermal storage tank. For this study, experimental facility was constructed, which was composed of experimental thermal storage tank, hot and cold water storage tanks, boiler, chiller, data acquisition system, etc.. Visualization and lab scale experimental result showed that radial curved type diffuser was the highest degree of stratification among the four diffuser shapes.
