Dish형 태양열 집광시스템의 집열성능에 관한 실험적 연구

Dish type solar thermal energy system can collect the solar energy upto 800℃. It has a concentration ratio of 800 and total reflector area of 49㎡. To operate the dish type solar collector, optimal design of the absorber is very important, then we evaluate thermal performance of solar receiver and obtain the efficiency plot of system. The efficiency of receiver test and collected energy tests were carried out to evaluate the thermal performance of the system. We find that system efficiency is stable in case of flow rate of above 61pm. The thermal efficiency of receiver is 68% and the ratio of collected energy is 65.7% in flow rate of 81pm. The performance showed that the maximum efficiency and the factor of thermal loss is 66%, 72% and 0.0658, 0.0045 in flow rate of 61pm and 101pm, respectively.
