Abstract
Over the past century, integrated adsorption desalination (AD) systems have gained significant interest as sustainable solutions to the increasing global freshwater demand. Although many hybrid AD systems are presented, ample energy efficiency improvement still exists by integrating humidification de-humidification (HDH) and air conditioning (AC) for water production and thermal comfort cogeneration. In this regard, a comprehensive mathematical model is developed to evaluate key performance metrics for two AD/HDH/AC proposed system configurations. Additionally, multi-objective optimization is employed to identify optimal operating conditions. The results reveal that the hybrid system (Scheme #2) demonstrates high productivity and GOR. At a heating water temperature of 50 °C, it produces up to 181.4 kg/h of water with a maximum GOR of 3.74. This productivity increases to 216.2 kg/h with a GOR of 1.69 under maximum output conditions. For Scheme #1, maximum productivity is 115 kg/h at a GOR of 1.67, while the peak GOR is 3.86 at 65 kg/h. The specific cost per kilogram of water (SCPW) varies between $0.015 and $0.0165, depending on the operating conditions. Key parameters affecting system performance include chilled and heating water temperatures, flow rates, and the mass ratio of the humidifier. The findings show that integrating AC with HDH and AD provides superior performance, offering dual benefits of thermal comfort and water desalination.
期刊介绍：
Thermal Science and Engineering Progress (TSEP) publishes original, high-quality research articles that span activities ranging from fundamental scientific research and discussion of the more controversial thermodynamic theories, to developments in thermal engineering that are in many instances examples of the way scientists and engineers are addressing the challenges facing a growing population – smart cities and global warming – maximising thermodynamic efficiencies and minimising all heat losses. It is intended that these will be of current relevance and interest to industry, academia and other practitioners. It is evident that many specialised journals in thermal and, to some extent, in fluid disciplines tend to focus on topics that can be classified as fundamental in nature, or are ‘applied’ and near-market. Thermal Science and Engineering Progress will bridge the gap between these two areas, allowing authors to make an easy choice, should they or a journal editor feel that their papers are ‘out of scope’ when considering other journals. The range of topics covered by Thermal Science and Engineering Progress addresses the rapid rate of development being made in thermal transfer processes as they affect traditional fields, and important growth in the topical research areas of aerospace, thermal biological and medical systems, electronics and nano-technologies, renewable energy systems, food production (including agriculture), and the need to minimise man-made thermal impacts on climate change. Review articles on appropriate topics for TSEP are encouraged, although until TSEP is fully established, these will be limited in number. Before submitting such articles, please contact one of the Editors, or a member of the Editorial Advisory Board with an outline of your proposal and your expertise in the area of your review.
