在太阳能溶液除湿蒸发冷却空调系统实验台上,以LiC1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LiC1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。
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 LiC1 solution as liquid desiccant. The effect of air and solution inlet parameters on the dehumidi- fier 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 simi- lar tendency among different desiccant.
