摘要/Abstract

摘要： 介绍了固体除湿转轮、热泵型内冷固体除湿床以及与热泵结合的多级固体除湿装置3种固体除湿装置的工作原理,建立了相应的传热传质模型,并通过实验验证了模型的准确性。通过模拟方法,对比了3种除湿装置的除湿效果。结果表明,热泵型内冷固体除湿床的传热传质过程最优,转轮的近似等焓的空气除湿过程最差,与热泵结合的多级固体除湿装置通过分级和内冷改进了转轮的近似等焓的空气处理过程。除湿转轮的再生温度一般在80℃以上,其他两种除湿装置的再生温度均在50℃以下;在达到相同送风含湿量时,除湿转轮的除湿与再生过程近似沿等焓线变化,送风温度很高;而其他两种除湿装置的送风温度比较低,COP能达到4以上。

Abstract: Three kinds of solid desiccant dehumidifier are compared, which are desiccant wheel dehumidifier, heat pump driven inner-cooling desiccant dehumidifier, and heat pump driven multi-stage desiccant dehumidifier.Mathematical models of desiccant wheel and multi-stage desiccant dehumidifiers are set up and validated by experimental results.The dehumidification performance of the three dehumidifiers shows that the inner cooling desiccant method gives the best heat and mass transfer process, while the desiccant wheel dehumidifier is the worst.Regeneration temperature of desiccant wheel is usually above 80℃, while that of inner cooling desiccant bed and multi-stage desiccant bed are both below 50℃.To obtain the same humidity ratio of the supplied air, air states of desiccant wheel is near isenthalpic line with high supplied air temperature, while the COP of inner cooling desiccant bed and multi-stage desiccant bed is above 4 with low supplied air temperature.
