摘要
通过在太阳能集热再生器理论建模中考虑玻璃盖板的温度影响分别提出单向吸收、双向吸收及简化改进3种太阳能集热再生模型。通过对几种数值模型计算结果进行对比发现:玻璃盖板温度差异较明显但再生用空气温度相差较小且溶液和玻璃盖板之间的辐射换热对溶液再生性能影响较大。最后通过实验验证双向吸收模型的正确性及简化改进模型对双向吸收模型的可替代性。
Considering effect of the glazing temperature in the model of solar collector/regenerator （C/R）, the models of unidirectional absorption, bidirectional absorption and simplified improvement were put forward, respectively. Comparing the calculations of several models, it is found that the glazing temperatures have obvious difference, opposite to the less deviation of air temperature for kinds of models. Moreover, the radiation heat between the solution and the glazing has more effect on performance of solar C/R. At last, the bidirectional absorption model is validated by comparing with the experimental results and the simplified improved model can substitute for bidirectional absorption model.
