本文从固体吸附除湿的角度出发,对目前已有的除湿能效评价指标进行了分析,指出了所存在的问题,并在此基础上提出了2种新的评价指标:吸附能效和脱附能效。这2个评价指标综合考虑了吸附剂的吸附自由能和脱附活化能对材料特性的影响,突出了吸附材料对吸附除湿的影响,可为今后吸附剂的选型与优化、吸附除湿能耗的降低提供判别依据。
In this paper, from the point of view of solid adsorption dehumidification, the existing indicators of dehumidification and energy efficiency evaluation are analyzed, the existing problems are pointed out, and two new evaluation indexes are proposed: adsorption energy efficiency and desorption energy efficiency. The two evaluation indexes comprehensively considered the influence of adsorbent’s free energy of adsorption and activation energy of desorption on material properties, highlighted the influence of adsorbent on adsorption and dehumidification, which could be used for selection and optimization of adsorbents in the future, adsorption and desiccant energy consumption Provide a basis for determining the reduction.
