传统极限工况有最大制冷量工况和最大制冷系数工况,在此其间,必存在一特殊工况,使得既具有较大的制冷量,又具有较小的功耗,此工况即为“最优工况”。本文首先对半导体最优工况进行了理论分析,推导出最优电流的理论公式;再对一小型半导体制冷箱进行实验,通过调节电流改变工况,分析了8种工况实验下的性能参数变化情况,对实验数据进行回归分析,得出回归方程,从而找出最优电流对应的最优工况。在此工况下进行工作,即可获得较大的制冷量,又可消耗较小的功率,从而提高了半导体制冷器的制冷性能。实验结果与理论分析结果基本吻合。
In the traditional extreme working condition, there is a maximum cooling capacity case and a maximum refrigeration factor case, in the meantime, there must exist a special working condition, which not only has a larger cooling capacity but also has a smaller power consumption, which is “Optimal conditions ”. In this paper, the theoretical analysis of the optimal operating conditions of the semiconductor is carried out firstly, and the theoretical formula of the optimum current is deduced. Then a small semiconductor refrigerator is tested. By adjusting the operating conditions of the current, the performance parameters Changes, the experimental data regression analysis, regression equation was drawn to find the optimal current corresponding to the optimal operating conditions. Working in this condition, you can get a larger cooling capacity, but also consume less power, thereby enhancing the semiconductor cooling performance of the refrigerator. The experimental results are in good agreement with the theoretical analysis.
