Abstract

Revolutionizing energy-efficient air conditioning, this study unveils a breakthrough in baffle plate falling film dehumidification by integrating 0.5 wt% nanocarbon tubes (NCTs) into a LiCl/H₂O solution. Through a validated numerical model, we rigorously analyzed six pivotal inlet parameters air velocity, liquid flow rate, air humidity, liquid concentration, air temperature, and solution temperature across 86 simulation cases designed via central composite design (CCD). Employing response surface methodology (RSM), we developed highly accurate regression models (R² > 0.99, P < 0.0001) to predict outlet air humidity, liquid concentration, air temperature, and solution temperature. The incorporation of NCTs boosted the moisture removal rate (MRR) by an impressive 27 % compared to conventional LiCl/H₂O, with peak performance at air velocities of 3.5 m/s and solution temperatures of 25 °C. Multi-objective optimization pinpointed ideal conditions, maximizing dehumidification efficiency while slashing energy demands. This pioneering work showcases NCT-enhanced desiccants and optimized baffle designs as a game-changer for sustainable, high-performance liquid desiccant systems, paving the way for greener climate control solutions.

利用纳米碳管增强LiCl/ h2o溶液优化折流板降膜除湿机的性能

通过将0.5 wt%的纳米碳管（nct）集成到LiCl/ h2o溶液中，这项研究揭示了在挡板降膜除湿方面的突破，从而彻底改变了节能空调。通过一个经过验证的数值模型，我们严格分析了6个关键入口参数-空气速度，液体流量，空气湿度，液体浓度，空气温度和溶液温度-通过中央复合设计（CCD）设计的86个模拟案例。采用响应面法（RSM），我们建立了高精度的回归模型(R2 >；0.99, P <；0.0001)来预测出口空气湿度、液体浓度、空气温度和溶液温度。与传统的LiCl/H₂O相比，nct的加入将除湿率（MRR）提高了27%，在空气速度为3.5 m/s、溶液温度为25°C时达到峰值。多目标优化确定理想条件，最大限度地提高除湿效率，同时削减能源需求。这项开创性的工作展示了nct增强的干燥剂和优化的挡板设计，作为可持续的高性能液体干燥剂系统的游戏规则改变者，为更绿色的气候控制解决方案铺平了道路。

期刊介绍： International Communications in Heat and Mass Transfer serves as a world forum for the rapid dissemination of new ideas, new measurement techniques, preliminary findings of ongoing investigations, discussions, and criticisms in the field of heat and mass transfer. Two types of manuscript will be considered for publication: communications (short reports of new work or discussions of work which has already been published) and summaries (abstracts of reports, theses or manuscripts which are too long for publication in full). Together with its companion publication, International Journal of Heat and Mass Transfer, with which it shares the same Board of Editors, this journal is read by research workers and engineers throughout the world.
