干燥剂系统应用于各种各样的工业和日常使用产品，包括新的HVAC装置。本文沿着介绍了液体除湿技术的概况，并以表格形式列出了液体除湿器的实验性能数据、经验除湿效率和传质关联式。这一领域的最新趋势表明，混合系统是当前暖通空调行业的兴趣，不仅用于高潜在负荷的应用，而且用于改善室内空气质量。本文提出了一个全面的比较参数分析的填充床除湿器的三种常用的干燥剂材料，即三甘醇，氯化锂和氯化钙，使用经验的相关性从文献中的除湿效果。该分析揭示了显着的变化和异常的趋势之间的预测不同的相关性相同的操作条件下，并强调需要基准的除湿性能的除湿器。
Desiccant systems find applications in a very large variety of industrial and daily usage products including the new HVAC installations. An overview of liquid desiccant technology has been presented in this paper along with a compilation of experimental performance data of liquid desiccant dehumidifiers, empirical dehumidification effectiveness and mass transfer correlations in a useful and easy to read tabular format. The latest trends in this area suggest that hybrid systems are of current interest to HVAC industry, not only for high latent load applications but also for improving indoor air quality. The paper presents a comprehensive comparative parametric analysis of packed bed dehumidifiers for three commonly used desiccant materials viz. triethylene glycol, lithium chloride and calcium chloride, using empirical correlations for dehumidification effectiveness from the literature. The analysis reveals significant variations and anomalies in trends between the predictions by various correlations for the same operating conditions, and highlights the need for benchmarking the performance of desiccant dehumidifiers.
