Thermal Performance Evaluation on Direct and Indirect Solar Thermosyphon System

직접 및 간접식 자연순환형 태양열 온수급탕시스템의 열적성능 해석

A preliminary study has been done to investigate the thermal performance of an indirect system. Direct systems are also analyzed and the results are compared with those of the indirect system where possible. Values from the numerical simulation show very good agreement with the measured data. Although the indirect system is generally expensive and not as efficient as direct systems, it is more reliable in frigid weather conditions like the winters in Korea.
