摘要

与传统空调系统相比,干燥剂冷却机制是控制空气湿度的替代方法之一。本文对混合干燥剂在液体干燥剂除湿系统中的应用进行了实验研究。采用三甘醇(TEG)与不同比例的氯化镁(MgCl2)混合作为杂化干燥剂。用除湿率和焓效率等参数对除湿机的性能进行了测试。与100% TEG相比,TEG和MgCl2的共混物具有更好的除湿率(MRR)。随着干燥剂流量和空气流量的增加,各配比的MRR和水分有效性均有所增加。25% MgCl2和75% TEG浓度的共混物具有较高的MRR和除湿效果。研究表明,如果使用一种优化的TEG和MgCl2的混合物代替纯TEG作为干燥剂,它将克服TEG的高粘度问题,成为有希望的可持续能源候选之一。

Experimental Analysis and Parametric Study on the Dehumidification System Using Liquid Hybrid Desiccants-A Source of Sustainable Energy
The desiccant cooling mechanism is one of the alternate methods to control the air humidity compared to the conventional air conditioning system. An experimental investigation has been carried out in the current research using a hybrid desiccant in a liquid desiccant dehumidification system. Triethylene glycol (TEG) mixed with different proportions of magnesium chloride (MgCl2) has been used as the hybrid desiccants. The performance of the dehumidifier was measured using the parameter moisture removal rate and enthalpy effectiveness. The blends of TEG and MgCl2 gave a better moisture removal rate (MRR) as compared to 100% TEG. The MRR and moisture effectiveness increased with the increasing desiccant flow rate and air flow rate for all of the blend ratios. The blend with 25% MgCl2 and 75% TEG concentration had relatively high MRR and dehumidification effectiveness. The study reveals that if an optimized blend of TEG and MgCl2 is used as the desiccant instead of a neat TEG, it will overcome the high viscosity problems of TEG and become one of the promising candidates for sustainable energy sources.
