摘要
基于对太阳辐射的分析,研究了外层空间太阳能集热表面的转化过程与效率,并以获得集热表面转化效率最大为条件,理论计算了不同情况下太阳能集热表面的最佳工作温度,给出了转化效率与系统工作温度及最佳工作温度随环境温度的变化关系曲线,对影响最佳工作温度的因素进行了讨论.
Based on the exergy analysis of solar radiation,the efficiency and process of exergy transformation of solar collector surface in outer space are studied. Under the condition of achieving the maximum exergy transformation efficiency,the optimal operation temperatures on the solar collector surface are calculated theoretically for different circumstances. The relationship curves of the optimal operation temperature with environment temperature are given out and the factors having influence on the optimal operation temperature are discussed in the paper.
