Abstract

This study aims to experimentally demonstrate a liquid desiccant systems effectiveness by using thermo-chemical fluid, such as aqueous solution of calcium chloride. This study evaluated the effect of operating temperatures on air properties (temperature, relative humidity, and moisture content) and system effectiveness by varying air flow rates. The system's functionality was influenced by the operational temperature and air flow rate, and the dehumidification effectiveness was higher at low operating temperatures and low airflow rates. An ANN metamodel-based control strategy is also proposed for implementation in hybrid thermo-chemical networks with the help of system performance data and real-time data. The suggested ANN model's results were validated using a variety of measuring techniques, including the RMSE, MAPE, correlation (R), and coefficient of determination (R²). The proposed ANN analysis achieved an excellent correlation between predicted and experimentally measured data.

先进空调液体干燥剂系统优化的实验与数值研究。

本研究旨在通过实验证明液体干燥剂系统使用热化学液体（如氯化钙水溶液）的有效性。本研究评估了操作温度对空气特性（温度、相对湿度和含水量）的影响，以及通过改变空气流速对系统有效性的影响。系统的功能受运行温度和空气流速的影响，在低运行温度和低空气流速下，除湿效果更高。在系统性能数据和实时数据的帮助下，还提出了一种基于 ANN 元模型的控制策略，以便在混合热化学网络中实施。利用各种测量技术，包括 RMSE、MAPE、相关性 (R) 和决定系数 (R2)，对所建议的 ANN 模型的结果进行了验证。所建议的 ANN 分析在预测数据和实验测量数据之间实现了极好的相关性。

期刊介绍： We publish original research from all areas of the natural sciences, psychology, medicine and engineering. You can learn more about what we publish by browsing our specific scientific subject areas below or explore Scientific Reports by browsing all articles and collections. Scientific Reports has a 2-year impact factor: 4.380 (2021), and is the 6th most-cited journal in the world, with more than 540,000 citations in 2020 (Clarivate Analytics, 2021). •Engineering Engineering covers all aspects of engineering, technology, and applied science. It plays a crucial role in the development of technologies to address some of the world''s biggest challenges, helping to save lives and improve the way we live. •Physical sciences Physical sciences are those academic disciplines that aim to uncover the underlying laws of nature — often written in the language of mathematics. It is a collective term for areas of study including astronomy, chemistry, materials science and physics. •Earth and environmental sciences Earth and environmental sciences cover all aspects of Earth and planetary science and broadly encompass solid Earth processes, surface and atmospheric dynamics, Earth system history, climate and climate change, marine and freshwater systems, and ecology. It also considers the interactions between humans and these systems. •Biological sciences Biological sciences encompass all the divisions of natural sciences examining various aspects of vital processes. The concept includes anatomy, physiology, cell biology, biochemistry and biophysics, and covers all organisms from microorganisms, animals to plants. •Health sciences The health sciences study health, disease and healthcare. This field of study aims to develop knowledge, interventions and technology for use in healthcare to improve the treatment of patients.
