| 摘 要： | 本文对抛物面G型辐冷器,在水平视场角变化的情况下不同工况下的制冷性能进行了计算。通过数值计算发现,视场角的减小导致辐冷器制冷性能的明显下降,虽然视场角影响辐冷器的因素很复杂,但最后的结果是两者呈现出良好的线性关系。其次,通过对辐冷器降温特性的研究,提出了通过改变辐冷器外壳控温方式来减小视场角变化对辐冷器制冷性能的负面影响,计算结果表明这种解决措施是非常有效的。 |
| 关 键 词： | 视场角 辐射制冷器 制冷性能 |

| Abstract: | The performance of a parabolic G style radiant cooler under different conditions was computed by numerical method with the view angle of the radiant cooler as a variable parameter. It is found that the reduction of view angle significantly deteriorates the working performance of the radiant cooler. Although the inner heat exchange of a radiant cooler is very complicated, the cold stage temperature can be expressed as a linear function of the view angle in its variation range studied. A method is proposed to reduce the negative effect of the decrease in view angle. The major idea of the method is to change the temperature-controlling mode of the ambient housing. Numerical results show that the method is very effective. |
| Keywords: | view angle radiant cooler working performance |
