| 摘要: |
| 在太阳能溶液除湿蒸发冷却空调系统实验台上，以LiCl溶液为除湿剂，用空气进出口含湿量差和除湿效率作为除湿过程的性能评价指标，来研究叉流除湿器的除湿性能。通过实验数据分析了溶液、空气进口参数对除湿性能的影响，并利用实验数据建立适用于LiCl溶液的叉流除湿器的除湿效率和传质系数的实验关联式，发现与实验结果的吻合程度很好，误差在15%以内，能够利用这些关联式来准确的计算叉流除湿器的除湿性能，可供叉流除湿器设计参考使用。最后将实验结果与相关文献进行比较，结果表明：不同的除湿剂对叉流除湿器的除湿性能的影响基本相同。 |

| Abstract: |
| To describe the heat and mass transfer performance of the cross-flow dehumidifier, this paper measures the dehumidifier’s moisture removal rate and dehumidifier effectiveness on the test bed with liquid desiccant evaporative cooling air-conditioning system, which is driven by solar energy and uses LiCl solution as liquid desiccant. The effect of air and solution inlet parameters on the dehumidifier is analyzed by the experiment. The new empirical correlation is developed with the experimental data, and the error of the calculation is within 15% compared with the test value. It can be used to calculate the performance of the cross-flow dehumidifier and design the cross-flow dehumidifier. Compared with other results available in the literature, the impacts of air and solution inlet parameters show similar tendency among different desiccant. |
